In general, injection molding refers to the process of pressing plastic resin melted with high pressure in a mold, and cooling and solidifying it to create a molding.
Injection is classified into a multicolor or general injection machine. In case of a multicolor injection machine, two colors (red and transparent) or three colors (red, transparent, and another color) are emitted simultaneously.
In case of a general injection machine, only one color (gray or transparent) is emitted.
The injection process is an important factor when deciding about the exterior quality of a product.
Thus, high-level technology is needed.
Configuration of Injection Molding
Classified into Thermoplastic resin and Thermosetting resin
Thermoplastic resin -
Thermosetting resin -
|Injection mold||A frame to make a product of a desired shape with melted raw material.|
|Injection machine||It is a piece of mechanical equipment that allows a plastic material to be melted and injected into a mold from a high-pressure nozzle to produce a desired product.|
The general conditions of an injection machine and an injection mold to make a product of a desired shape.
(e.g., pressure, speed, distance, time, temperature, etc.)
Other facilities connected to an injection machine or an injection mold to meet proper molding conditions.
(e.g., dryer, chiller, water heater, etc.)
