The previous blog entry covered five top questions when researching a Michigan plastic blow molding company. This blog entry covers some of the other considerations when looking for a local plastic blow molding company. We have specified Michigan blow molding company because that is where we are located. However the information isn’t specific to any one state or province. Blow molding companies in southwest Michigan and blow molding companies in China and elsewhere can held to the same standard.
- Combine molds for a variety of plastic shapes – Separate mold pieces combined for many different sizes & shapes. Blow molding may not be the best option for your part, or possibly one element of you part requires blow molding and another part is best suited for injection molding. A consultation with an experienced engineer can offer the most efficient applications to produce a high quality product.
- Location – Finding a plastic blow molding manufacturer that has submitted the lowest cost but is located out of state or the country can quickly lose its’ advantage when packaging, freight costs and lead times increase. If the facility you choose has a considerable cost advantage but is located in a nearby state and once freight and shipping is determined still results in a cost savings and meeting shipment scheduling is guaranteed to meet turn around times, close proximity may not be a concern. Many Michigan manufacturers require tier suppliers to be within a specific mile radius which limits options in some cases. If for instance, you are an appliance manufacturer you may not have rules for suppliers location but the convenience of having your parts manufacturers close can reduce cost and valuable lead time.
- Turn around – As noted above with the location, turn around time can be critical in the manufacturing industry. The more time required to manufacture parts the more cost per part, thus increasing the cost of the final product. When comparing press capabilities, a penny difference per part of one million parts on a slower press adds up quickly. Considerations must be taken with the speed of design, prototyping, changes, production and fulfillment. If molded parts can be completed within other facilities at the same level of quality at a much faster speed it can reflect in a huge cost savings to the customer and more sales to the manufacturer.
- Assembly and Packaging – Often times blow molded or injection molded parts are just one piece of a larger item. For instance blow molding for manufacturers would include the tires on the 4-wheeler tote-a-long in the photo above . However, in this example the body of the product also requires blow molding. Bringing the components together to a completed product in one facility instead of shipping parts to be blow molded in one spot then assembled in another, then packaged in another location is time consuming and expensive. SPI Blow Molding and SPI Industries in Michigan produce the plastic molded parts, assemble, package and ship to the manufacturer or directly to the wholesaler or distributor. Other items such as food bins that need micro sized parts added and attached can be assembled in SPI blow molding and injection molding facilities. All products will need to be packaged whether products are individual parts, partially assembled or complete products ready for sale. Determining packaging is an important step in the final stages of the manufacturing process. How products will be packaged, from large boxes that will be transported on skids, to small items placed in plastic bags and then into cardboard boxes for shipping or individually into customer provided point of purchase packaging all adds cost and time.
- Warehouse direct shipping – Once the plastic molded parts are complete and packaged what is the best method to get products to the next stage? Options from the blow molding manufacturer and injection mold manufacturer for shipping or delivery of items include shipping to warehouses, production facilities, or customer’s business. Some blow molding companies like SPI Blow Molding, offer warehousing and factory direct shipping, and even direct to retailer or end user shipping. This is a valuable service for companies who do not have a fleet of delivery trucks or a fleet service they retain. Keeping manufacturing, assembly, packaging and shipping within one facility reduces cost, staff, and liability. Time savings include, reduced order tracking, order placement, product receiving, staff management, reduced time monitoring and tracking of spending and payroll.
