Investment Casting
Investment casting is a manufacturing process in which a wax mold is coated with a refractory ceramic material. Once the ceramic coating material has dried and hardened, the wax melts and leaves the final product geometry in the internal cavity. Molten metal is poured into the cavity where the wax mold is located. The metal solidifies in the ceramic cavity, cools, and then the ceramic is removed from the metal casting. The result of this process is net-accurate to near-net-accurate metal parts that can be used in a wide range of applications in a variety of industries.
The process of investment casting
Investment casting is a manufacturing process in which a liquid material is poured into a ceramic mold that contains a cavity of the desired shape and then allowed to solidify. The solidified part is the casting, which is removed from the ceramic mold to complete the process. The steps in the investment casting process are as follows:
Step 1: Engineering Review
The first step in the manufacturing process is a complete Design for Manufacturing (DFM) review with the customer.
This will include an evaluation of the print dimensions associated with the investment casting process, wax injection pattern build considerations (e.g., gate locations), backshell material requirements and expected tolerances for part fit, form and function, and final inspection criteria to determine a mutually acceptable part.
Step 2: Mold Design and Fabrication
The process begins with a precision-designed wax injection mold to produce a wax mold representative of the final part.
These design considerations are discussed with the mold maker and a mold design is created.
Molds are designed and built to replicate millions of wax parts over their lifetime.
