Unlike soft silicone molds, a hard plastic mold is typically machined from steel or aluminum and is designed to withstand the high pressures and temperatures involved in injection molding cycles. Surface polishing or texturing is applied to influence part appearance and release characteristics.

Cleaning protocols must remove residual material without damaging precision surfaces. Manufacturing the Mold Components Rough machining removes excess material to bring the steel close to the final shape.
This virtual testing phase reduces costly iterations and ensures that the hard plastic mold will perform as expected before metal cutting begins. Alignment pins and precision machining ensure that the halves meet cleanly without flash.

The cavity, core, and supporting structure must be engineered to distribute pressure evenly while minimizing cycle time and material waste. Initial testing, often called tryout, involves injecting real material under controlled conditions to validate fill patterns, part quality, and cycle efficiency.
