In addition to being super-flexible, Plast-O-Wax offers excellent fill and flow. Plast-O-Wax is known for its extraordinary memory -- injections won't break despite the roughest handling. That means that your injection failure rates can be sharply reduced and productivity sharply increased. Plast-O-Wax also offers easy release from rubber molds, wax patterns with smooth, glossy surfaces and minimal shrinkage.
