Draft Angles: Apply a taper (usually 1 to 2 degrees) to all surfaces parallel to the mold opening direction to ensure easy part ejection. Injection Molding Part Design for Dummies: A Comprehensive

Chapter 5: Gate Placement – Where the Plastic Enters

The gate is the tiny opening where molten plastic squirts into the mold cavity. Where you put it changes everything. [ ] Wall thickness is uniform (±25% max)

  • [ ] Wall thickness is uniform (±25% max)
  • [ ] All vertical faces have at least 1° draft (check with draft analysis tool)
  • [ ] Inside corners have radius ≥ 0.5x wall thickness
  • [ ] Rib thickness ≤ 60% of wall thickness
  • [ ] Undercuts are eliminated or designed for side-actions (slides or lifters)
  • [ ] Nominal wall is between 1.5mm and 3.5mm (unless using engineering resin)
  • [ ] Gate location is marked on the model (optional but helpful)
  • [ ] Parting line is clearly defined

External Radii: Should be 1.5 times the wall thickness to maintain that all-important uniform wall thickness. 5. Selecting the Right Material
