Experience has shown us that very few machined plastic parts require annealing after machining to meet dimensional or performance requirements.
Annealing plastic sheet.

Annealing acrylic thermoform plastics annealing is the process of relieving stresses in molded or formed plastics by heating to a predetermined temperature maintaining this temperature for a set period of time and slowly cooling the parts sometimes formed parts are placed in jigs to prevent distortion as internal stresses are relieved during.
Annealing is the process of relieving stresses built up in the materials during processing.
This white paper covers the factors that make necessary the annealing of polycarbonate a plastic material and highlights the problems that may arise if materials are not annealed.
Many of the high quality materials including engineering plastics and high performance materials are run through a specific annealing process by the manufacturer to reduce internal.

Rod and sheet present with different stress characteristics due to their unique geometric shapes.
Stress can be caused by any process that intrudes heat to a plastic.
The annealing process is performed on plastics to remove stress that could potentially result in cracking wearing poor chemical resistance or degradation of the performance of the material.
At miller plastic products we carefully analyze each part to determine the best annealing method for your application requirements.
Stress relieving of engineering plastics also known as annealing can play an important role in the quality of machinable plastics and machined plastic parts.
The importance of annealing plastic rod and sheet.
Annealing is a secondary operation specifically a heat treatment and isn t typically done for all plastics parts or even in most plastic industries but it is an important technology here at elite plastics.
Proper annealing of your plastic rod or sheet is directly related to the quality of the finished machined plastic part.
For example plastic rod reacts in a radial fashion since turned diameters.
Annealing plastics can increase the longevity of your machined plastic parts and components saving you time and money.
Generally speaking most stock shapes are annealed after molding using a proprietary stress relieving cycle to minimize any internal stresses that may result from the manufacturing process.
