 Custom Cast Urethane Parts Manufacturing


Custom cast Urethane have excellent physical properties, such as, high abrasion, good load bearing characteristics, excellent tensile strength and tear resistance. Cast Urethane are tough and durable materials which facilitate significant advantages over metals or plastics.


Urethanes may be cast with fiber or glass reinforcement material to enhance the load, flexure and EMI characteristics of the final part. Additionally, cast urethanes may be post mold processed using milling and other processes to enhance feature tolerances, such as size and location.


Urethanes are processed initially from a hot liquid, therefore mold pressures are low,  reducing tooling cost and mass. Molds may be manufactured from steel, aluminum, or even wood. Creating a reverse engineered tool made from Urethane for plastic, or metal parts is simplified due to the low viscosity of the urethane.
