Tips for tooling design with Tritan


 
What makes for effective molding of Eastman Tritan™ copolyester? Reviewing all aspects of design-from concept to secondary operations-early on in the process is crucial to end-stage success.
 
Tooling design review is one important step in the process that will help determine what type of gating system is right for your device. Here are four quick tooling design tips for injection molding with Tritan:
 
  • Proper gating selection
    Select a compatible gating style for the selected resin. Most conventional cold gating styles work well with Tritan copolyesters, including sub, pin, fan, edge, sprue, and diaphragm gates.
 
  • Design tooling with good cooling/thermal control
    Copolyesters require good thermal control throughout the cavity for optimal processing.
 
  • Design tooling with a plan for venting 
    Poor venting can result in burn marks and incomplete fill. Suggested vent depths for Tritan copolyesters are typically 0.0005-0.0015 in.
 
  • Design tooling with a plan for ejection 
Parts should be adequately supported during ejection to avoid part deformation/breakage.
