The granuals form of Thermoplastic material purchased from BHEL approved suppliers is fed through feed hopper of injection Moulding machine. The material under in to the barrel and machine through hopper which is kept at the temperature ranging from 130oC to 265oC for various Thermoplastic material such as LDPE, HDPE, PVC, ABS, HIP, Nylon, Glass filled nylon, Arnite and Polycarbonate. The barrel is heated through set of heater creating a profile of temperature in respective feed zone. The granuals material passed through combination of screw rotating in side the barrel and appear at the other end i.e. in to the nozzle in the form of Homogeneously mix and uniformly viscous melt. The melt is injected according to the weight of component in to the mould tightly hold closed with the help of suitable clamping devices. After injection of melt the pressure is kept on till the heat is conducted and through temperature control media. After the article get cool and solidified in the mould the mould is opened out and subsequently the component is ejected from the mould.
