    How Can I Prevent Molding Stress on Polycarb

    Greeting fellow professionals. I was wondering if you could share some ideas on some process techniques that can be used to effectively reduce molded in stress on PC parts. How can one effectively ameliorate molded in stress that could take away from PC's impact resistance?

    Thank You All

    Make the gates bigger
    Make the gates even bigger yet
    Slow the injection speed
    Anneal the parts after molding
    Round off any sharp corners in the mold cavity
    Raise the mold temperature
