Although injection molding is the most popular plastic molding process, there are many other processes available for manufacturing plastic products. Most 3D rapid prototyping is optimized for injection-molded parts, since the tooling investment and part complexity are the most extreme for this process. Other processes like blow molding, vacuum forming, rotational molding, and extrusion are also specified for processing plastic parts. Each process has its own set of unique design criteria, choice of materials, and type of part geometry.
Blow-molded bottles, for example, are typically manufactured in polyethylene (PE), polyethylene terephthalate (PET), or polypropylene (PP). Prototyping a PE blow-molded bottle in a 1-mm wall utilizing any of the rapid prototyping methods is not available today. However, a blow-molded PE bottle can be prototyped by creating an SLS or FDM blow mold and molding a few samples. There are several vendors offering this type of service. The same is true for other plastic molding processes, where the mold is either 3D printed or CNC machined, and a small quantity of parts are molded in the actual material. Prototyping plastic parts based on the actual material and molding process provides you with the most accurate representation of the final production part. Injection-molded prototype parts in the actual material will be almost identical to the production parts. They can be tested and evaluated based on the performance of the specified resin, molded-in stresses, as well as the part tolerances. Large structural foam molded parts are best suited for CNC fabrication or FDM, with a 70% to 80% part density. Since structural foam molded parts are typically large, you may be required to split them into smaller pieces that are printed and assembled into one larger piece.
