The process of injection molding is used for producing large scale of identical plastic articles through the technique of high precision engineering. The China plastic auto mould manufacturers injection molding machine transforms granular plastic into final molded parts, followed by the process like melting, injecting, packing and cooling. The most common materials used in this process are Acrylonitrile-Butadiene-Styrene ABS, Nylon PA, Polycarbonate PC, and Polypropylene PP. Injection molding is well known for the wide range of applications like car bumpers, battery boxes, wheelie bins, truck body panels, etc. After getting the outline about injection molding machine, now it is the time to know the components.  
A typical injection molding machine encompasses the below listed major components. Injection systemHydraulic systemMold systemClamping systemCooling SystemControl systemInjection System- This equipment comprised of a hopper, barrel assembly, a reciprocating screw and an injection nozzle. In the process of manufacturing the plastic, it helps in confining and transporting the plastic when it flows through the feeding, compressing, degassing, melting, injection, and packing stages.Hydraulic System- It actually provides the power to open and close the mold. Integrated in the machine, it is responsible to build and hold the clamping tonnage. In addition to this, it drives the reciprocating screw and fuel ejector pins and moving across mold cores.  
A wide array of hydraulic equipments such as hydraulic motors, hydraulic fittings, hydraulic tubing, pumps, valves, and hydraulic reservoirs are required to fuel up the process. Mould system- This set up involves stationary, tie bars and moving platens that accommodate cavity, sprue and runner systems, cooling channels and ejector pins. Most importantly, it is a heat exchanger in which the molten thermoplastic takes the solid state as per the desired shape and dimensional properties defined in the cavity. Clamping System- This system takes care of opening and closing of mold. Also, it carries the constituent parts of the mold and drives enough force to prevent mold from opening contours. The clamping pressure can be generated either by a mechanical (toggle) lock, hydraulic lock or a combination of both. Cooling System- In the complete cycle of injection molding technique, it is the most time consuming process. A long time implies that molder must charge more for the same part of article design. At the time of product design process, you should consider thermal analysis capabilities to structure the cooling design for the tools. The result produced will be a low cost tool that runs steadily and keep your cost low. Control System- It governs consistency and repeatability in the machine operation.  
All the parameters like temperature, screw speed, position, pressure, injection speed, and hydraulic position are monitored through the control system. It has a direct impact on the quality of final part and the cost-effectiveness of the process. These are the basic parts of an injection molding device that regulates the comprehensive process of manufacturing plastic parts, producing the most precise and definite shape of the object.
