Product Details

85HP Screw Type ChillerWater Cooled Industrial Chillers Water Chiller unit For Plastic mold

Plastic extrusion processing is a commonly used plastic processing method.

It can melt plastic and extrude it through a die to make tubes, plates, rods and other materials of various shapes. During the extrusion process, the plastic raw material needs to be heated and melted first, and then the molten plastic is sent to the die through the screw.

The shape of the extruded material is then determined by the shape of the die.

The importance of plastic cooling rate

1.In plastic injection molding processing, the cooling of plastic materials is a major factor affecting production efficiency and product quality.

2.Cooling rates that are too fast or too slow can have negative effects on plastic products.

The impact of too fast cooling rate on product quality

1.In plastic processing, rapid cooling can improve production efficiency, but it will cause problems such as product deformation and shrinkage.

2.Rapid cooling will produce high stress on the surface of the plastic, which will affect the internal structure of the plastic, leading to problems such as shrinkage, dimensional deviation and surface smoothness of the product.

3.In addition, too fast cooling rate will cause bubbles, cracks and other defects inside the product, affecting the service life of the product.

The impact of too slow cooling rate on production efficiency and cost

1.Too slow a cooling rate will reduce production efficiency and lead to increased costs.

2.Because slow cooling causes the molecular structure inside the plastic to gradually form, it prolongs the entire processing cycle and increases costs.

3.In addition, a too slow cooling rate will increase the shrinkage of the product, resulting in substandard product dimensions.
