Before you can manufacture a plastic part you need to have a solid design in
place. Once done, you can build an injection mold to meet the product
The role of the Design Engineer is critical in this process. They assess the
part design and make modifications and recommendations based on key product
requirements including product usage and function. The engineer will need to
² How will the part be used? Is it a standalone product or a component of a
² What are the dimensional and tensile requirements?
² Does the part need to withstand elements, pressure, chemicals?
A plastic injection mold design is built with these criteria in mind. Mold
cavities, vents and gate placement will vary based not only on the part design
but the type of resin as well. Taking all of these manufacturing factors into
account is a challenging task and one that requires a strong knowledge base, not
only of mold design but the injection molding process as well.
