Reduced replacement of venting plugs
Reduces Casting Defects
Drastic decrease of pin hole, mis-run and gas run defects
Other Benefits
Works in all types of injection molding applications
High Casting Productivity
Fast and easy exchange of venting plugs, Easy cleaning of molding dies.
Ready of Custom-Made
Pore sizes range from 0.03 to 0.5mm; length and diameter of vent to meet your needs

Application Recommendations for Injection Molding

The variety of plugs offered fit a wide spectrum of polymer needs.  Vent diameter should be chosen to correspond to these needs.  Examples are listed below.

  1. 0.03mm diameter for use with polyethylene and polypropylene
  2. 0.05mm diameter used in Nylon, ABS and polycarbonate.
  3. 0.10mm diameter vents for highly viscous polymers.
