Webbrecessed to reduce gate scars, long gates, and the possibility of impact directly on the gate. Filled materials require special consideration in gate location. Weld line formations can be weak if they fall in areas that will bear stress or impact. This is particularly true if the wall thickness in the weld is thin – i.e., less than 0.080 inches. WebbRubber products shrink after molding and during post molding processes. The rate at which they shrink varies, but is mostly determined by the compound. Operating parameters also affect shrinkage, but usually to a lesser extent. Rubber molds are cut to compensate for shrinkage, but shrink rates vary so that parts may be
