Skim Gates and Core Plates

    

Skim Gates are manufactured using tin-coated steel sheet or non-ferrous sheet, depending on the metal being cast. Standard perforation is #6 (.075" hole on .125" centers). Standard material thickness is .015". For special applications, the size of perforation holes, the perforation pattern, and thickness of material can be modified to meet your specifications. They are used to control the flow of metal and remove impurities as molten metal enters the mold. Core Plates are manufactured using mild steel, usually 1" (25,4 MM) or smaller.

These are generally tinned and used in the gating system to restrict the flow of metal, or to create larger bearing surface for chaplets against cores or molds. Because of their application(s), no standard material thickness applies. It is determined based on your specifications.

The information listed in the chart details general characteristics of dimensional design for Skim Gates and Core Plates.
