TOP 10 TIPS FOR DESIGNING INJECTION MOLDED PLASTIC PARTS

Nov 22, 2016·1. Uniformity is best. Constant wall thicknesses throughout your part will provide the best flow. Nominal wall thickness should be between 2-3mm. The recommended minimum is 1mm and the maximum is 4mm for conventional injection molding processes. 2. Smooth trumps sharp. Use radii when possible and avoid sharp transitions between wall sections. 3.

Part Design Guidelines for Injection Molded Thermoplastics

Plastic threads used for joining parts can be machined or molded-in. • When designing molded-in threads, avoid feathered edges and include radiused roots in order to minimize stress concentrations P and to keep the walls uniform. •Sharp edges can …

Design More Effective Clips on Plastic Injection-Molded Parts

Stress and Flexibility on Plastic Clips. There are three factors affecting the stress caused by flexing a clip. The first is the length of the flexing arm. A longer arm creates less stress for a given deflection of the end. If your design limits the length of the clip’s flexing arm, you can increase the arm’s effective length in several ways.
