Description of injection molding parameters   1、 Drying temperature Definition: temperature required for drying polymer in advance to ensure molding quality Functions: 1. Remove water from raw materials 2. Ensure the quality of finished products Setting principle: 1. The polymer will not decompose or agglomerate (polymerize). 2. The drying time should be as short as possible and the drying temperature should be as low as possible without affecting the drying effect 3. Drying temperature and

Injection molding, also known as plastic injection molding, is an injection molding method. The advantages of the injection molding method are fast production speed, high efficiency, automatic operation, a wide variety of patterns, shapes from simple to complex, and sizes from large to small. Moreover, the product size is accurate, the product is easy to be updated, and it can form parts with complex shapes. Injection molding is applicable to mass production, products with complex

Description of basic elements of injection molding   1. Pressure The action pressure provided by the pressure system (oil pump) of the injection molding machine or the driver’s motor is mainly used in various action programs such as the injection device, the Plastic melting device, the mold opening and locking device, the ejection device, the shooting table device, and the core pulling device. After the control panel of the injection molding machine inputs relevant parameters,

What is injection molding? Injection molding, also known as injection molding, is an injection molding method.

How to deal with bubbles in injection molding According to the causes of bubbles, the countermeasures are as follows: 1) When the wall thickness of the product is large, the cooling speed of its outer surface is faster than that of the center part. Therefore, as the cooling proceeds, the resin in the center part shrinks while expanding to the surface, resulting in insufficient filling in the center part. This condition is called a vacuum
