Steel investment casting foundry uses SLA Rapid Prototypes.

PA Precision Cast Parts, Inc. (PPCP), a steel investment casting foundry in central PA, has recently utilized a new technology, called SLA Rapid Prototypes. The prototypes aid customers in bringing a concept into a usable casting.

Investment casting is often the most practical and cost effective method of creating steel components. The lost wax casting process will yield a net or near net shape that can meet the design needs of end users of castings. The drawback, however is that the capital cost of building permanent tooling to replicate the patterns in wax on an ongoing basis can be challenging due to costs. Costs increase when the engineer is attempting to verify that the end product will work as predicted. Often times, a tool to create a 20 pound investment casting can approach nearly $10,000. The most effective solution to keep costs down is rapid prototyping.

Rapid prototyping exploits a SLA Pattern, which can be generated using a CAD file. SLA is a pattern used in place of a wax pattern for the lost wax process of investment casting. The investment company utilizes the SLA pattern and processes it through the foundry in the same manner as the wax pattern. The result is a casting that can be put into use to prove the process without the heavy investment in permanent tooling. Since PPCP has created castings for a customer using SLA Patterns, the result has allowed the customer to evaluate the effectiveness of their overall design. Once verified, a decision can be made on investing in permanent tooling with the security of knowing the design functions properly with no additional changes needed.
