Molding Wax Patterns

The characteristic of investment casting wax pattern depends on not only the properties of wax itself but also the injection molding condition greatly. SHINWA SANGYO Co., Ltd. has two injection machines. The wax patterns are made with these machines and are examined on the shrinkage rate, strength, surface smoothness and other properties.
