The most used manufacturing process for the plastic mold spare parts fabrication is Injection molding. With the use of injection molding, a wide variety of products been manufactured which vary in their complexity, applications, and sizes. Injection molding machine, mold, and raw material are the main things used in the injection molding process. In the injection molding machine, plastic firstly melted then injected into the mold then it cools down and hardened into the final part.
Melting the raw plastic and guide it into the mold is the purpose of the injection unit. Reciprocating screw, hopper and the barrel are the mold spare parts.
1. First, dry the polymer granules and then keep it in the hopper, where the coloring pigments are mixed with these granules.
2. The granules are kept into the barrel, where they are all together heated, mixed and moved towards the mold by a variable pitch screw. The screw and the barrel build up the pressure and melt the material. The ram then moves forwards and with the help of the runner system, the melted plastic is injected into the mold where it fills the whole cavity. As the material cools down, it re-solidifies and takes the mold’s shape.
3. Finally, a solid part is pushed out by the ejector pins as the mold opens. The process repeats as the mold closes.
The repetition of the whole process is very fast as the cycle takes only 30 to 90 seconds depends on the part’s size. After the part ejection, it is allocated on a conveyor belt or in a holding container. Injection-molded parts require little processing and are ready to use right away.
The working principle of the injection molding machine is similar to the syringe used for injection. It uses the thrust of the screw (or plunger) to inject the melted plastic into the closed cavity and then obtains the process of the product after curing and setting.
