Design Considerations for PPSU
Optimize your PPSU injection molded parts with these critical design guidelines for superior performance and manufacturability.
Wall Thickness
Recommended: 1.5-6.0mm for optimal flow and strength
Maintain uniform thickness to prevent warping and sink marks
Draft Angles
Minimum 0.5° per side, preferably 1-2°
Essential for easy part ejection and surface quality
Radii & Corners
Inside radius: 0.5-1.0mm minimum
Avoid sharp corners to reduce stress concentration
