Injection Molding Plastic Parts

Designing Plastic Parts for Injection Molding

Designing Plastic Parts

Designing plastic parts is a complex task involving many factors that address application requirements. “How will the part be used?” “How does it fit with other parts in the assembly?” “What loads will it experience in use?” In addition to functional and structural issues, processing issues play a large role in the design of an injection-molded plastic part. How the molten plastic enters, fills, and cools within the cavity to form the part largely determines what form the features in that part must take. Adhering to some basic rules of injection molded part design will result in a part that, in addition to being easier to manufacture and assemble, will typically be much stronger in service.

Dividing a plastic part into basic groups will help you to build your part in a logical manner while minimizing molding problems. As a part is developed, always keep in mind how the part is molded and what you can do to minimize stress.

Injection Molding Applications

Plastic injection molding is the preferred process for manufacturing plastic parts. Injection molding is used to create many things such as electronic housings, containers, bottle caps, automotive interiors, combs, and most other plastic products available today. It is ideal for producing high volumes of plastic parts due to the fact that several parts can be produced in each cycle by using multi-cavity injection molds.

Some advantages of injection molding are high tolerance precision, repeatability, large material selection, low labor cost, minimal scrap losses, and little need to finish parts after molding. Some disadvantages of this process are an expensive upfront tooling investment and process limitations.

Common Use Cases

  • Packaging
  • Electronics & Telecommunications
  • Consumer goods
  • Mechanical parts (including gears)
  • Medical devices
  • Most other plastic products used
