What is Processing and Drying Temperatures of Plastics

All people working in the plastic profession should know that plastic drying while manufacturing is a normal phenomenon. Someone working at a plastic processing factory should clearly know the processing temperature of all plastic material. Let’s dive into our article talking about polymer processing temperature.

The Importance of Processing and Drying 

As we all know, processing material should be done perfectly to produce quality products. Inaccurate processing can lead to the production of faulty and deficient products and can also sometimes cause damage to the mold and also the molding machine.

The importance of drying temperature is also an essential part of the process, as too much moisture can cause several processing problems. Most polymers exhibit some level of polarity and absorb some amount of moisture from the air. The impact moisture will have depends on the polymer and its applications.

Before preparation of resin for injection or production in injection molding, the material should be properly dried according to the manufacturer’s recommendations. Not doing that, a manufacturer is risking the quality of the part. Common issues are brittleness, bubbles, sink marks, irregular moldings, and lower mechanical properties.

Adequate drying can also significantly lower the risk of hydrolysis and part failure. Hydrolysis is a chemical reaction in polymers that ruptures the covalent bonds in its chain, reducing its mechanical properties.

However, using a drying system and not always do the job of improving the quality and consistency of the injection molding process. On the shop floor, consistent monitoring of the dew point and moisture content of resins is necessary to ensure they’re meeting manufacturers’ recommendations for dryness.

Final Thoughts 

That’s all I wanted to say about the processing and drying temperature of plastics. The data published in the article is well researched and comes from reliable sources. However, the data is shared just for information purposes. Consulting your material supplier about the processing and drying temperature of the material you want to work with is the best way to go.
