What is annealing process: The so-called annealing process is actually baking the material in an oven or dryer. This is a process that polymer materials need to be treated.

We all know that steel is a material with good extension properties. All must be treated by annealing process, the purpose is mainly to eliminate or reduce the prestress of the material, improve or enhance the comprehensive performance of the material properties.

PEEK material annealing process of different manufacturers is not consistent with the type of material and physical properties have a certain correlation, the advantages of annealing treatment: PEEK sheet is a polymer, semi-crystalline thermoplastic engineering plastics, the glass transition temperature is close to 150 ℃.

Earlier had been considered an expensive plastic; PEEK sheet is generally made by extrusion, baking. Oven-heated baking, just extruded PEEK sheet due to a sudden drop in temperature out of the mold, will cause slight deformation or bending of the surface of the sheet, affecting the final use of the profile experience. Therefore, it is necessary to heat the rear channel to make the sheet more flat; because the PEEK material is a special high-temperature resistant polymer plastic, after extrusion molding, the molecular pre-stress and the rigidity of the material is not eliminated, which will affect the use of the sheet and processing.

If the baking time is short, the molecular stress is not eliminated cleanly, which will leave a danger to the subsequent cutting and processing; even a certain part may appear functional defects, and the length of the control time will affect the performance of the PEEK sheet. It plays a vital role; through the treatment of good annealing process, the molecular stress of the material is basically eliminated, which plays a great role in the processing and deep processing of the rear plate, as well as the carving of shaped materials.

Mainly embodied in: the annealing processed plate surface is flatter, superior toughness and strength; secondly, PEEK plate will not appear in the cutting of irregular cracks or cutting collapse, cracking, processing will not appear larger fluctuations in the deformation and cracking.
