Electrical discharge machining (EDM) creates intricate details and tight corners that conventional milling cannot achieve. Alignment pins and precision machining ensure that the halves meet cleanly without flash.

Material and Tolerance Specification Choosing the right steel grade for the mold cavities and cores is critical for longevity and performance. Continuous monitoring of key indicators such as fill time and part weight ensures ongoing optimization.
This virtual testing phase reduces costly iterations and ensures that the hard plastic mold will perform as expected before metal cutting begins. Surface finishes are specified in micro-inches, with polishing or coating applied to meet cosmetic or functional requirements.

Assembly and Testing Once individual components are completed, they are assembled into a complete mold set, including ejection systems, cooling channels, and locating mechanisms. Initial testing, often called tryout, involves injecting real material under controlled conditions to validate fill patterns, part quality, and cycle efficiency.
