How to Use This Calculator
- Enter part weight (g), nominal wall thickness (mm), and flow length from gate to farthest point (mm).
- Select material viscosity class (low, medium, or high-viscosity resin).
- Review recommended gate thickness, gate width, gate cross-section area, and gate land length.
- Ensure gate thickness is 50–75% of nominal wall thickness to allow clean gate removal.
- Compare estimated fill time to your target — undersized gates cause excessive shear and fill problems.
