Injection molding, also known as injection moulding, is a molding method that combines injection and molding. At a certain temperature, the completely melted plastic material is stirred by a injection moulding screw, injected into the mold cavity with high pressure, and cooled and solidified to obtain a molded product. This method is suitable for mass production of parts with complex shapes and is one of the important processing methods. The process of injection moulding step by step can be roughly divided into the following 6 stages: Mold clamping, injection, pressure keeping, cooling, mold opening, and product removal. By repeating the above process, products can be produced periodically in batches. The molding of thermosetting plastics and rubber also includes the same process, but the barrel temperature is lower than that of thermoplastic injection molding, and the injection pressure is higher. The mold is heated. After material be injected, it needs to undergo a curing or vulcanization process in the mold, and then release the film while it is hot .

Plastic Moulding Processes Characteristic

The combination of easy formability and flexibility of resin and rigidity, strength and heat resistance of metal can be combined to make complex and exquisite injection molding machine parts.
In particular, using the combination of the insulation of resin and the conductivity of metal, the molded products made can meet the basic functions of electrical products.
The pre-molding combination of multiple inserts makes the post-engineering of product unit combination more rational.
Insert products are not limited to metals, but also cloth, paper, wires, plastics, glass, wood, coils, electrical parts, etc.
For rigid molded products and bending plastic molded parts on rubber gaskets, after injection molding on the substrate to make an integrated product, the complicated operation of arranging the sealing ring can be omitted, making the automatic combination of subsequent processes easier.
Because it is the joining of the molten material and the metal insert, compared with the press-in molding method, the gap of the metal insert can be designed to be narrower, and the molding reliability of the composite product is higher. .
Choose appropriate resin and molding conditions, that is, for products that are easily deformed and damaged (such as glass, coils, electrical parts, etc.), they can also be sealed and fixed by resin.
Choose an appropriate mold structure, and the insert product can also be completely enclosed in the resin.
The combination of a vertical injection molding machine, a manipulator, and an insert product alignment device, etc., most of the insert molding process can realize automated production.
After the insert is molded, it can also be made into products with hollow grooves after core hole processing.

Injection Molded Plastic Parts Advantages

The advantages of injection plastic mold parts are fast manufacturing speed, high efficiency, operation can be automated, variety of colors, shapes can be from simple to complex, size can be from large to small, and the size of the product is accurate, the product is easy to update, and it can be made into complex shapes. Parts and injection molding are suitable for mass production and molding processing fields such as products with complex shapes.
