From design and tooling, to quality control and assembly, to packing and fulfillment, SPI supports your success by delivering quality parts on time, at a fair price.

From concept to completion

In this competitive market, companies seek every opportunity for cost savings. Maintaining high levels of quality while meeting increased demands for faster turn offers a competitive edge. Working with one experienced plastic molding company instead of working with multiple companies at different stages of the manufacturing process ensures consistency and accuracy for your plastic parts. Selecting full service manufacturing from SPI Industries helps you breathe easy.

Benefits of Full Service Manufacturing of Plastic Parts

Shorter production times

Keeping all phases of the plastic part manufacturing process with one company, reduces production time. Once production begins, each step in the process is set and scheduled. With full service manufacturing, all communication and coordination is streamlined into a proven system and managed by a team of professionals. Each part moves smoothly from tooling to delivery.

Reduced plastic part manufacturing costs

At our full service manufacturing facilities, engineers, designers, and manufacturers work together on each project. The close proximity of the departments allows them to communicate quickly and efficiently. If there are adjustments needed throughout the manufacturing phase they will be identified and addressed at each step. This level of quality control can’t be obtained when each phase of production is outsourced to different companies.

Streamline communication

Working with one company decreases errors caused by inefficient communication. We’ve all encountered issues when changes have not been explained accurately or in a timely fashion. Whether in business, or in our personal lives, limiting the amount of people involved in a process reduces the chance for miscommunication. With full service manufacturing you contact one team. There is no need to schedule meetings with multiple teams or determine logistics for communicating across different time zones.

Time is money.

Each step in the manufacturing process that can be eliminated saves time and money. Because a full-service manufacturing provider is accountable for all aspects of a project, often a higher level of personalized service will result. The buck stops with the full service manufacturing provider. There is no blaming other vendors. Ensuring all processes are correct in the very beginning helps projects move smoothly through each stage. Additional cost savings are returned through discounted rates offered by many full-service manufacturers that niche companies do not offer.

Keeping everything under one roof also eliminates the need to allocate additional funds for packaging and transportation between manufacturing facilities. Staff training, estimating, billing, reports, and correspondence is streamlined when all phases of a product are completed by one company.

How To Get an Accurate Estimate for Plastic Molded Parts

Accurate Estimate for Plastic Molded Parts

Are you a developer, designer or inventor of products that requires blow molded or injection molded plastic parts? Do you think you are ready to bring your new idea to market? Are you looking for a price quote for blow molding or injection molding for your new product?

SPI is regularly contacted by developers, designers and inventors, who’s products are at varying stages of development. More sophisticated and experienced customers may have 3D CAD files or prototype molds built before calling us. Some customers may have 2D drawings or a homemade prototype mocked up. While, still others bring only sketches or concepts. We have examples of each maturing into successful product launches.

While the appearance of the product or the visible parts may be well thought out, the function, material and plastic molded part design requires a great deal of exploration. Below, we discuss some of the design questions we consider to deliver Quality Parts at a Fair Price.

We have specific questions that need answers before SPI can provide an accurate estimate on part pricing. We look at ways to help design for ease of manufacture at both the part design as well as the tool design. Producing a clear and thorough estimate for plastic molded parts design and development requires a great deal of communication and expertise.

Before you are ready to manufacture your idea, these questions are important to consider:

What is the end use of your product?

  • Will the part be exposed to chemicals?
    If a product is going to be exposed to bleach, or ammonia or other chemicals, there are specific resins that we will recommend to used that will ensure the integrity of the plastic part over time and use.
  • Will your product hold food or beverages for human consumption?
    There are specific guidelines required for food safe storage products. Because of the stringent guidelines, not all injection molding or blow molding companies offer food safe plastic solutions.
  • Will your part be exposed to extreme temperatures or other environmental conditions?
    These considerations will allow your molder to offer recommendations of resins and special additives that may be used to allow your part to function under extreme conditions.

Specific Design Elements will determine best processing technology for Plastic Molded Parts

  • What are the dimensions of your plastic molded parts?
    The size and annual demand of your part will dictate which plastic molding process is required. SPI can help you determine the best processing technology for your product. Typically, small, complex parts such as handles for tools or pens are ideal for injection molding. Hollow objects such as bottle and beverage containers are best suited for blow molding. Where does your product fit? We can help.
  • How complex is your part? Will your part need to be flexible?
    Is your part a simple rectangle with one notch that will connect with another part? Does your part have multiple levels, notches, clips or bellows? Does your part start large and get progressively smaller? Do any elements of your part need to move or be removable? Is a portion hard, while another component pliable such as a clip that must be squeezed into a hole to later expand? The complexity of the design will dictate the type of material, time needed for the mold development and tooling.

What materials are best for your plastic molded part design?

  • Which polymers or resins are best for your product?
    If you are not familiar with the many types of plastic materials on the market, a qualified plastic molder can help you make the best selection. Once a molding engineer knows the end use of your product, the size, quantity, and processing technology, they should be able to offer options for the best material selection for your plastic molded parts.

As you can discern from the many questions posed above, there are many variables that will determine the best solution to manufacture, assemble and deliver your product. The manufacturing company you choose should be a partner in the success of your product. Give SPI Blow Molding or SPI Industries a call, we look forward to partnering with you to help launch your new product. We will support your success by delivering Quality Parts, On Time at a Fair Price.

Why Choose Injection Molding?

Injection molding is the most commonly used type of plastic product manufacturing in use today.  The process can be used to manufacture items that consist of over 18,000 different types of plastic materials, such as thermoplastics and some types of thermosets and elastomers.

The injection molding process has existed since 1872; the first products manufactured by this process were billiard balls made by John and Isaiah Hyatt. However, injection molding can be used to manufacture almost any solid or open-ended object, from hair combs to the dashboards of cars.  The plastic injection molding process consists of injecting a molten plastic material into a metal mold and letting it cool and dry.  Designing molds for injection molding requires a lot of expertise; a mold must be designed so that the part will be of uniform thickness and allow it to be easily ejected from the mold.  SPI Industries is experienced in designing molds for injection molding. We will sample the mold and make minor adjustments until they are just right for manufacturing before we begin mass producing your products.

Often creating prototype parts will help in both part design as well as tool design. Having a prototype part for more complicated designs will generally help to reduce the amount of adjustments during the sampling process.

Why Choose Blow Molding?

In contrast to injection molding, blow molding is the process used for making hollow plastic parts.  It is also required when making items that vary in thickness in different parts of the object, such as gas tanks.  Blow Molding is commonly used for higher volume parts that are currently being roto-molded, due to a faster cycle time when compared to roto-molding. However, the nature of blow molding usually has longer cycle times and more processing variation than injection molding.

Temporary Plastic Safety Barricades

plastic safety barricades - the boyz or the boys

Plastic safety barricades are used to block off areas from automotive or pedestrian traffic. From a single barricade to a continuous, obstruction free, fencing system, safety barricades provide clear guidance through work zones. Highly visible barricades prevent people from entering dangerous work zones.

Plastic safety barricades have increased in popularity

Safety barricades are used in emergencies and in situations when accidents have occurred or have the potential to occur. To ensure timely response, safety barricades that are lightweight, easily assembled, and easy to break down and store are very popular. Using plastic safety barricades meet these demands.

Plastic safety barricade uses

Plastic safety barricades are used heavily in road construction. Those of us in the midwest know orange barrel season all too well! The ever present orange plastic cones used to keep people in their driving lanes and out of off-limit areas are universal indicators of caution.

Most A-frame barricades traditionally constructed of wood are now entirely constructed of plastic. From the A-frame sides to the 2 x 4 rails with reflective caution stripes, these temporary plastic safety barricades are weather resistant, easy to install, break down, stack, and store until they are needed again.

Plastic safety systems also include temporary barricades for use inside buildings. The U.S. Occupational Safety and Health Administration offers guidelines for proper placement of barricades for protection of employees in all circumstances. From blocking off spills in cafeterias, closing off construction areas, blocking areas with limited access, warning of wet paint or wet floors, and many other precautionary instances, plastic safety barricades are in demand.

Benefits of Plastic Safety Barricades:

  • lightweight
  • durable
  • weather proof
  • damage resistant
  • color can be added during manufacturing process
  • stickers / labels can be applied
  • reusable – recyclable

free standing barricade -the boyzSPI Blow Molding manufactures plastic safety barricades in a product for both interior and exterior safety situations called, “The Boyz”. The Boyz are a unique plastic safety barricade. Each ‘boy’ is all one piece and is 80% larger than the standard tent sign at 31” wide by 41” high. There is no set up time or any additional parts needed for use. If the area requires sectioning off, multiple boys can be used to form a temporary, solid wall, maintenance barricade by joining them at the hands. The unique ‘boy’ shape is 1,271 square inches of bright yellow plastic.

Each boy has ‘Caution: Out of Order’ emblazoned across the chest and a stop sign on the helmet. Quick deployment of the wire stand on the back of each boy allows it to be free-standing. The wire doesn’t get in the way when multiple boys are joined together to form a solid pedestrian barricade. Once the area is secure again the lightweight ‘boy’ folds flat for convenient storage.

Use of ‘The Boyz’ and other plastic safety barricades in manufacturing plants, schools, offices, shopping centers and stores help keep visitors, children, personnel, contractors, and everyone in the facility safe. If you, or your organization, are looking for plastic safety barricades to alert people of hazardous situations with maximum visibility, ‘The Boyz’ may be a good solution. As the manufacturer of ‘The Boyz’ SPI is presenting them for purchase and delivery. Contact us today with any questions.

Made in Michigan – Oversized Blow Molded Plastic Tooth

Made in Michigan Art and Parts

Did you read about the oversized blow molded plastic tooth design that was created for an art installation? Did you know if was made in Michigan? SPI Blow Molding, Coloma, Michigan constructed the teeth for a toothquake. The toothquake resulted from the Tooth Fairy choosing to relocate from her gold dome in the sky to Northville, Michigan. IN case you missed it, the toothquake incident occurred during the Arts & Acts Celebration in Northville, Michigan on June, 17, 2016.

In advance of the celebration Dr Demray and his team researched blow molders from all over, including China. Thankfully, their research led them to SPI Injection Molding who then lead them to their sister company, SPI Blow Molding. Upon meeting the owners and engineers at SPI Blow Molding Dr, Demray and his team knew if they were going to get their oversized blow molded plastic tooth produced, SPI Blow Molding was the shop to do it. After the meeting Dr. Demray affirmed, “What great people” and a wonderful relationship was formed.

The Made In Michigan Toothquake Was a Success

Because the oversized blow molded plastic teeth were made in Michigan the art installation will be a significant addition to the Buy Michigan Now Festival to be held in Northville August 5th-7th. The structure is schooled to be in place for viewing at 371 E. Main St. – Northville, MI for the annual 4th of July parade, during the summer long Friday night Concert series in Town Square, for the Great Lakes Food, Art & Music Festival, the Heritage Festival, October in the ‘Ville and the Salute to Summer Festival. The Acci-DENTAL Masterpiece will come down in November, 2016.

The Acci-DENTAL Masterpiece is the cornerstone of an 8-month public awareness campaign focusing on children’s dental health. Dr. Demray is committed to educating parents about the importance of limiting sugar – exposing foods that have high hidden sugar content plus the importance of good oral hygiene… brush 2 x a day for 2 minutes and visit the dentist 2 x a year. This practice will contribute to a chid’s overall good health. In addition to the 3,333 teeth on display – Dr. Demray asked SPI to make 1,111 more – for an art exhibit to be held in February, 2017 – Children’s National Dental Health Month. Beginning July 1st parents, educators, heath care providers and anyone with an artistic flair can donate money to acquire a tooth,design it, return it temporarily for the exhibit and a chance to win. The suggested donation is $20. Details will be available are at toothfairyoverstock.com. A portion of the proceeds will go to the University of Detroit Mercy (UDM) Dental School Community Outreach Program. UDM has a mobile dental clinic that can go to the children, if they can’t come to the dentist.

SPI Industries is proud to have been a part of Dr. Demray’s life mission to share the message of preservation to children early in life. If you have a plastic product or part that you would really like to have made in Michigan and it needs blow molded please give SPI Blow Molding a chance to review the scope of your project. We pay attention to all of the details and design each plastic piece so each molded cavity is filled and will meet or exceed the highest quality standards and tolerances. Give us a call today.

AcciDENTAL Masterpiece – New Product Inventions as Art

New Product Inventions as Art Blow molded Plastic Teeth

At SPI Industry molding facilities we are fascinated with the creativity and ingenuity of new product inventions.  Product developers create new designs of existing products as well as completely new products that are designed to make life easier, more efficient, safer, or more attractive for everyone. We see all new product inventions as art!

Recently, we received the most unique new plastic molding product request yet. SPI Injection Molding and SPI Blow Molding have produced a full gamut of new product inventions from plastic game pieces, plastic home decorations, plastic parts for appliances, molded parts for healthcare, and many more but this new plastic product concept was a first.  It wasn’t too unusual when the SPI Injection plant in South Bend, Indiana received a request to produce a large plastic tooth. What was unusual was the story behind the tooth.

plastic blow molded teethNew Product Inventions as Art Installations

The over 3000 molded plastic teeth were needed to create a toothquake! The toothquake was represented in the form of a 23’ x 26’ wide waterfall from the second story windows of an old Victorian that is home to the dental office of Dr. Demray. The tooth quake, we learned, was a result of the seismic activity that arose from the relocation of everybody’s favorite childhood messenger, the Tooth Fairy. The Tooth Fairy was staying at Dr. Demray’s offices temporarily while her new warehouse was being constructed. As each night passed, the increase in children’s teeth could no longer be contained and caused a toothquake Friday, June 17, 2016.

Dr. Demray was the most obvious choice when the Tooth Fairy was in need of temporary living quarters. Throughout his over 40 year career Dr. Demray’s mission has been to educate kids about good oral care. Demray’s commitment to share the message of bone preservation and dental care to children is also demonstrated in his cast of characters such as Betsy Floss and Miss Ginger Vitis. These characters participate in parades and school presentations sharing the importance of good oral care for kids. Ever seeking new ways to bring dental care education to the forefront, Dr. Demray decided an art installation of thousands of teeth in a cascading waterfall from his second story offices would be impactful. As a long time Art & Acts supporter, Dr. Demray planned the art exhibit reveal for the opening day of the 2016 Northville Arts & Acts celebration.

When the concept was conceived Dr. Demray and his staff hoped the teeth would be made in the United States. When Dr. Demray’s staff contacted SPI Industries they called SPI Injection Molding plant in South Bend, Indiana. After a short discussion it was determined SPI Blow Molding plant in Coloma, Michigan would be the best approach for the production and molding of the plastic teeth.

SPI Blow Molding understood the teeth would be used to help educate kids on the importance of dental care. The SPI team quickly learned their efforts would also be paramount in the relocation of the Tooth Fairy to Northville, Michigan. This was no ordinary plastic tooth to be used in dental displays or for training for the dental industry!

Fulfillment of the order in time for the Arts & Acts Celebration in Northville set to begin June 17, 2016 was a fun and rewarding experience for the SPI Industry team.

Do you have new product inventions, art installations or even a new twist on an old product that needs attention to detail and experienced engineers to construct? Give SPI Injection or SPI Blow Molding a call today. We’d love to sink our teeth into it.

Read more about how Dr. Demray’s future plans for the teeth to benefit dental care awareness in future blogs.

Benefits of Thermoplastic Elastomers for Injection Molded Goods

Benefits of Thermoplastic Elastomers

Also referred to as thermoplastic rubber, thermoplastic elastomers (TPE) have become increasingly popular for a wide spectrum of products and applications. Below we cover some of the benefits of Thermoplastic Elastomers and how they have changed the look and feel of many products on the market today.

The speed and the ease of processing for plastic injection molding and plastic blow molding also makes it a popular choice for manufacturers and molders. Thermoplastic elastomers can be used in countless extrusion and injection molded applications. When compared to traditional resins, thermoplastic elastomers can be molded in shorter cycles to allow for quick turn round of molded goods.

TPE is also a solution for products that need to perform in a variety of temperatures including plastic products that will be exposed to the outdoors.

ADVANTAGES and BENEFITS OF THERMOPLASTIC ELASTOMERS INCLUDE:

  • Processing ease and speed
  • Design flexibility
  • Lower fabrication and production costs
  • Lower energy consumption
  • Resistance to solvent and abrasion
  • Resistance to weathering
  • Improved product performance
  • Shorter cycle time
  • Lower part costs per finished piece
  • Broader range in product density
  • Product consistency
  • Environmentally Friendly – recyclable scrap
  • Resistance to heat and cold
  • Can be injection molded, blow molded and thermoformed

These benefits of TPEs are just some of the reasons SPI Blow Molding and SPI Injection Molding recommend thermoplastic elastomers for a wide range of products and part design applications customers bring to us. Molding custom plastic parts with top grade TPEs that can save time and money as well as stand up to seasonal climate change is important to our customers.

Do you have a product or part that could benefit by incorporating thermoplastic elastomers? Give us a call today. SPI Injection Molding and SPI Blow Molding experts will consult with you and your team to determine if thermoplastic elastomers could save you time and money on your next part design project.

There are many plastic resin options available when injection or blow molding manufactured parts. The considerations vary depending on the end use of your product. For the highest success, research the properties of each plastic, the expense, life span, heat capabilities, and strength before you hit the injection molding or blow molding manufacturing phase.

Give us a call today to discuss best options for your custom product. SPI Injection Molding located in Indiana and SPI Blow Molding in Michigan provide engineering and molding services throughout the mid-west. Our mold and production experts understand the advantages of Kostrate® for food safe products and the advantages and disadvantages of many other plastic resins best suited for specific products and their use.

BPA Free Kostrate or Polycarbonate for Plastic Bottles and Containers?

BPA free Kostrate or polycarbonate BPA free low BPA for food storage

BPA free Kostrate or polycarbonate (PC) for packages and containers?  Polycarbonate has become a standard in the plastics molding industry. For many years it couldn’t be beat for home and kitchen applications that involved direct contact with food and beverages. Clear polycarbonate’s inherent shatter-resistance, lightweight, and optical clarity are advantageous for any product that will be shipped and displayed for purchase. Combine those qualities with heat resistance and low BPA, it became a popular choice for tableware, refillable bottles, and reusable food containers that can be stored in the refrigerator and heated in a microwave. Now with BPA free Kostrate sharing similar characteristics, manufacturers have even more options when it comes to food safety.

Examples of clear polycarbonate packages and containers:

  • Reusable 5-gallon water bottles
  • Baby bottles
  • Bulk food containers
  • Tableware such as plates and cups
  • Food storage containers for storage and microwave heating

Clear polycarbonate is also popular in the construction industry. Because it is lightweight and transparent it is often used as a glass replacement. Available for purchase in corrugated or smooth panels, clear polycarbonate is used in greenhouses, as enclosures and as roofing material. A popular brand that has become synonymous with clear polycarbonate is Lexan®. Panels can be cut to size and are available at many big box hardware stores.  If transparency is not desired polycarbonate plastic is available in a variety of colors too with as many or more applications.

Since 2003 the new plastic in town is Kostrate®. For blow molding and injection molding purposes the requests we receive most these days are for clear, BPA free plastics for food storage and containment. Bottles and packages of all shapes and sizes are created as well as office products, hardware products, healthcare and cosmetics packaging to toys, outdoor products, digital media and computer components and devices. For the food industry Kostrate® is most desirous for its safe BPA free status. Bisphenol A (BPA) is a key building block of polycarbonate plastic, and although studies show very low migration of BPA from polycarbonate, Kostrate® BPA free status makes Kostrate® the safer choice for items that have direct contact with food or any product or substance that may be ingested.

BPA free Kostrate or polycarbonate packages and containers for food products and packaging?

Many researchers have studied the potential for trace levels of BPA to migrate from polycarbonate into food and beverages. Under typical use, studies show that the potential migration of BPA into food is extremely low. In these studies, the level found is more than 4000 times lower than the maximum acceptable or “reference” dose for BPA of 0.05 milligrams per kilogram body weight per day established by the U.S. Environmental Protection Agency. Essentially, an average adult consumer would need to ingest about 1300 pounds of food and beverage that is in contact with polycarbonate every day for an entire lifetime to exceed the level of BPA that the U.S. Environmental Protection Agency has set as safe.

These studies were conducted by government agencies in the US, Europe and Japan, as well as studies conducted by academic researchers and by industry professionals. However, other studies are cited that claim polycarbonate transfers more BPA than the aforementioned studies claim. Because of this there are a number of states seeking to ban the use of PC in some food packaging and beverage containers, including California. In these states a polycarbonate ban would be placed on baby bottles and beverage containers for kids three and younger and possibly other plastic containers, toys, etc. that come in contact with children of certain ages.

So, should you choose BPA free Kostrate or polycarbonate for your product? If BPA free is critical for the safety of your product we would recommend Kostrate® to you. If  you’re looking for product with heavy strength and it’s important but not critical to consumer safety, you may find polycarbonate suitable. If you are manufacturing a product that requires high impact strength PC wins against Kostrate in a wide temperature range roughly from below 0 to 300 F for PC and Kostrate is below 0 to 180 F.

If you have a product that requires a transparent, strong, but lightweight, plastic component or package give SPI a call today. We specialize in blow molding and injection molding of clear polycarbonate for use in many plastic products and product packaging. If you have food or beverages requiring transparent plastic packaging we have experience in both our blow molding and injection molding facilities for colored and clear Kostrate® packages and containers for food and most any other product you are producing to take to market. Give us a call today to determine which plastic will be the best choice for you product.
