How do I eliminate material stress

To ensure stable dimensions and a long life for precision component parts, it is essential that plastic materials are correctly heat treated or normalised to remove all material stress. On materials such as acrylic, these initial heat treatment processes can result in material shrinkage of between 2% and 4%.

All plastic materials used by Carville are heat treated before any machining operations take place. Subject to the component size, these heat treatment processes can require for 2 to 3 days.
