Tooling design – keys to success
Proper Gating Selection
 
  •Select a compatible gating style for the selected resin. Most conventional cold gating styles work well with copolyesters. For hot runner systems, valve gates should be used.
 
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.
 
Design Tooling with a plan for ejection
 
  •Parts should be adequately supported during ejection to avoid part deformation/breakage
