The beautiful looking plastic products are produced by injection machines. Injection molding machine is a machine for manufacturing plastic product by injection molding process. This machine will convert the solid raw plastic materials into molded part through melting, injecting and cooling process. Injection molding is the process of manufacturing parts by injecting materials into a mold. Mold is a hollow metal block into which molten plastic is injected to form a specified shape. Plastic injection machineries are widely used for manufacturing variety of parts from small elements to entire body parts of car. Plastic injection machine is divided into two units. They are clamping unit and injection unit. The three main function of clamping unit are opening, closing a die and ejecting a product. To melt the plastic by heat and then injecting the molten plastic into the mold are the function of injection unit. The two kinds of plastic injection machines are horizontal injection machine and vertical injection machine. Vertical injection machine are versatile and horizontal machine are very popular.Plastic injection machine

Horizontal injection machine consist of hopper, barrel, clamping unit, molding screw and heater bands etc. The hopper is like a funnel in shape, it is a place where plastic resin is placed for injection. The plastic can be fed into the hopper either automatically or manually. This machine consists of a series of heater band around the barrel, in order to maintain an even temperature throughout the injecting process. The screw has a dual function in plastic injection machines. They are, melting the plastic and injecting into the mold. After getting the required amount of molten plastic, the injection process will be started. To get a deep knowledge about Plastic injection machine, please go through my website .
