The initial step in the process of creating a custom metal mold is the design phase. This involves a detailed analysis of the part requirements, including dimensions, tolerances, material properties, and production volume. The design must take into account the manufacturing process that will be used, such as injection molding, die casting, or forging. It is crucial to work closely with engineers and designers to ensure that the mold design is feasible and can produce the desired results. Utilizing advanced CAD software can help in creating accurate 3D models of the mold, allowing for simulations and optimizations before the fabrication begins.
