Plastic deep moulding fills a part of the total moulding category that is dominated by injection and blow moulding. The process is adaptable both in its material and design capabilities and is generally restricted to the production of polyvinyl chloride (PVC) mouldings. However, it offers advantages such as modest tooling cost and the ability to produce small or large quantities in complex or simple shapes without size restriction. Because of modest tooling costs, fast prototypes are produced within a matter of days. Small product lots become economical with the process and a wide range of colors and finishes are available. Post operations (punching, printing, and decorating) are also available.
