Process: Plastic Injection Molding
Plastic injection molding is the most common process for production of plastic parts and products. In this process a plastic injection molding machine injects thermoplastic resins at high speed and high pressure into a steel mold.
Design Guidelines
When designing your injection molded part abide by the following guidelines where possible:
- Keep wall thickness constant throughout the part.
- Use a wall thickness not too thick or too thin for the kind of plastic material used.
- Use rounded corners instead of sharp corners where possible.
- Add draft to surfaces parallel to the direction of part ejection from the mold. This will ease part ejection.
- Limit the use of undercuts to reduce the required number of slides or side cores in the mold.
