Annealing – We Relieve Your Stress

Annealing is the process of relieving stresses built up in the materials during processing. Annealing plastics can increase the longevity of your machined plastic parts and components, saving you time and money!

At Miller Plastics, we carefully analyze each part to determine the best annealing method for your application requirements.

We understand the success of your plastic parts depends on the success of our processes.



Eliminates Crazing


Improves material rigidity


Prevents stress fractures


Increases chemical-resistance


Provides ability to sustain high temperatures without deflection


Thermoforming is the process of heating and forming many of today’s modern plastic materials into highly useful and cost effective parts such as control panels, displays and many others.

The automated process achieves faster cycle times than in other forming processes.

Only thermoplastic sheet can be processed by this method.

The plastic sheet is softened at the heating station. It then indexes to the forming station where the mold tools are located. The forming of the sheet is by a combination of air pressure and vacuum.

Many thermoplastics can be thermoformed; they include Polystyrene, Kydex®, Apet, Lexan®,  PVC, and more.
