Paper clip mold opened in molding machine; the nozzle is visible at right A injection molding machine with a robot. An injection molding machine (also spelled as injection moulding machine in BrE), also known as an injection press, is a machine for manufacturing plastic products by the injection molding process. It consists of two main parts ...
The critical components of a liquid injection molding machine include: [3] Injectors. An injecting device is responsible for pressurizing the liquid silicone to aid in the injection of the material into the pumping section of the machine. Pressure and injection rate can be adjusted at the operator's discretion. Metering Units.
Injection moulding (U.S. spelling: injection molding) is a manufacturing process for producing parts by injecting molten material into a mould, or mold. Injection moulding can be performed with a host of materials mainly including metals (for which the process is called die-casting ), glasses , elastomers , confections , and most commonly ...
Plastic forming machines, or plastic molding machines, were developed on the basis of rubber machinery and metal die-casting machines. After the inception of the polymer injection molding process in the 1870s, plastic-forming machines were rapidly developed up until the 1930s.
In hobby injectors injection pressure is generated manually by the operator, with a lever [1] [2] [3] or gear [4] [5] translating the operator's effort to the required pressure. The most common hobby injection machine uses a handle to press down with.

The basic concept of the micro injection molding process is quite similar to the regular injection molding process. In this process, a micro injection unit is integrated in the injection molding machine. When it comes to the production of micro components the machine and process technology mainly depend on the below points: [citation needed]
The metal injection molding market has grown from US$9 million in 1986, to US$382 million in 2004 to more than US$1.5 billion in 2015. A related technology is ceramic powder injection molding, leading to about US$2 billion total sales. Most of the growth in recent years has been in Asia. [2]
