All prototype tools are inspected and validated through sample molding prior to beginning any batch molding. This tooling method is widely used by the automotive and consumer durables industries to obtain real components within days for crash testing or pre-production builds.

Precision molding is the latest technology in the field of plastic injection molding. Precision molding is a type of plastic molding that is the most expensive and complex mold design process on the market. Polymer optics in precision injection molding are the key to developing high-precision molds, giving various unique advantages to the plastic injection molding development process. The process of precision molding causes the plastic to shrink. If the molding material has a high shrinkage capacity, the material will shrink during processing and the entire product will be destroyed.

The central part of the process is the mold, or the mold that contains the cavity and cooling system. A mold is made by a mold maker (or tool maker) from metal, usually steel or aluminum, and is precision machined to form the features of the desired part.
