Foundry Pattern Making
Pattern making is one of the first and most important steps in the casting process. Though many factors can have an impact on quality, a casting is only ever as good as its tooling.
For efficient and cost-effective castings, high-quality foundry pattern making is of vital importance.
The process of putting liquid metal into a mould, where it cools and solidifies, is known as casting. Everything from art pieces to engine parts can be made using the casting method. The mould cavity determines the shape, but something must shape the mould, which is where the pattern comes in.
Patterns are used to create a model for the object that will be cast. A pattern is imprinted on the mould, then liquid metal is injected into it and hardens in the shape of the original pattern.
Patternmaking is not as straightforward as the definition implies. A pattern must offer correct dimensions, have a way of departing the mould cavity without breaking it, compensate for solidification shrinkage and distortion, and contain a feeding system of gates and risers to transport liquid metal into the mould, in addition to sculpting the mould cavity. A failed casting might originate from any defect.
