Technoplast (Thailand) performs precision plastic (resin) machining in Thailand. Resins are sensitive to environmental factors like heat and humidity. By combining cutting with annealing, we can achieve higher-precision resin parts. In this article, we will introduce “annealing,” a type of heat treatment.

What is “Annealing”, an Essential Heat Treatment for High-Precision Resin Processing?

In resin processing, warping and distortion have long been challenging issues, primarily caused by residual stress* within the resin. Annealing is a heat treatment process used to remove this residual stress from the material and product, thereby preventing deformation of the processed parts.
*Residual stress: Forces that continue to act inward or outward within an object even after external forces are removed
