Plastic Injection Mold is mainly used in the production of thermoplastic parts. The corresponding processing equipment is injection molding machines. The plastics are first heated and melted in the heating cylinder at the bottom of the injection molding machine and then melted in the screw or screw of the injection molding machine. Driven by the plunger, it enters the mold cavity through the nozzle of the injection molding machine and the pouring system of the mold, the plastic is cooled and hardened to form. Its structure is usually composed of molding parts, pouring system, guide parts, push-out mechanism, temperature control system, exhaust system, support parts, and other parts, and it is made of plastic mold steel. The injection molding processing method is usually only suitable for the production of thermoplastic products. The plastic products produced by the injection molding process are very wide. From daily necessities to various complex electrical appliances and auto parts, they are all molded by injection molds. It is One of the most widely used processing methods in the production of plastic products.

Which is better, metal fan mold or plastic fan mold?
Metal blades with the same capacity (occupying space) can be made more than plastic.
The same number of metal blade tails can be shaped into winglets to provide better air volume in the aerodynamic theory.
The same power, well-made metal blades have more air volume than plastic blades. Well-manufactured refers to the use of metal characteristics to be plastic or to increase fan blades.
