Things you need to know about CNC machining injection molding

Injection molding is a manufacturing process of mass production parts.

This method can process the products with complex shape, precise size or inlay, and has high production efficiency Since the 1970s, there has been a kind of injection molding with chemical reaction, called reaction injection molding, which has developed rapidly.

Injection molding (injection molding) is a method to make thermoplastic or thermosetting molding plastics uniformly plasticized in the heated barrel, and then pushed into the cavity of closed mold by plunger or moving screw.
CNC machining
Injection molding is applicable to almost all thermoplastics. Injection molding has also been successfully used to form some thermosetting plastics. The molding cycle of injection molding is short (seconds to minutes), and the quality of molding products can be from several grams to dozens of kilograms. It can mold products with complex shape, accurate size, metal or non-metal inserts at one time. Therefore, this method has strong adaptability and high production efficiency.


Another significant advantage is that compared with the traditional manufacturing process (such as CNC machining), the rejection rate of injection molding is lower.Therefore it’s a top choice when trying to produce brand consistency and part reliability in high volume production
