The injection unit of injection molding machine is much like an extruder. The injection unit melts the polymer resin and injects the polymer melt into the mold. It consists of a barrel that is fed from one end by a hopper containing a supply of plastic pellets. The unit may be: ram fed or screw fed.

The injection unit consists of a granulate hopper, cylinder, screw, nozzle, heating bands and hydraulic drives and serves the purpose of melting and injecting the moulding material.

The reciprocating-screw machine is the most common. This design uses the same barrel for melting and injection of plastic.

The alternative unit involves the use of separate barrels for plasticizing and injecting the polymer. This type is called […]

Sincere Tech is professional China gas assist injection molding company, offer gas assisted injection molding products and other molding tooling and parts.

Gas-assist injection molding is a process that utilizes an inert gas (normally nitrogen) to create one or more hollow channels within an injection molded plastic part. At the end of the filling stage, the gas (N2) is injected into the still liquid core of the molding. From there, the gas follows the path of the least resistance and replaces the thick molten sections with gas-filled channels. Next, gas pressure packs the plastic against the mold cavity surface, compensating for volumetric shrinkage until the part solidifies. Finally, the gas is vented to the atmosphere or […]

Why Injection Molding in China?

Injection Molding in briefly explaining is a method that mold is gotten by cooling and solidifying the heated and melted material injected into the cavity via high pressure. The method is suitable for the mass production of parts with complex shape and is one of the important processing methods.

The injection molding process can be broadly divided into the following six stages of “combining mold – injection – packing – cooling – opening mold – product removal “, and once the above process is repeated, products can be continuously produced.

Asia’s biggest and world’s second, the “12th China intercontinental Injection Molding technology and products Exhibition” in Shanghai ended, in the getting together with […]
