What is a Cold Chamber Injection Molding Machine?
Cold chamber injection molding machine is a type of injection molding machine used to perform the injection molding process of thermoplastic materials. This type of machine is ideal for high-volume production and is often used to manufacture precision and complex parts such as auto parts, electronic equipment and medical devices.
A cold chamber injection molding machine has less control over the temperature of the material in the mold, hence the name "cold chamber". Instead of keeping the temperature high to pre-melt the material to be injected into the mold, this type of injection molding machine keeps the temperature of the material lower. This saves energy in the production process and extends mold life.
Cold chamber injection molding machines offer a fully automated production process that includes automatic injection, clamping and cooling functions. Such machines also have the ability to control material flow and injection speed using pre-programmed parameters. This facilitates quality control during the production process and improves the quality of the parts.
In conclusion, a cold chamber injection molding machine is an efficient injection molding method used for the production of high precision parts. This type of machine offers a fully automated production process, with the advantages of saving energy and extending mold life.

How Does a Cold Chamber Injection Molding Machine Work?
A cold chamber injection molding machine produces plastic parts by melting plastic granules and injecting them into a mold. However, unlike a conventional injection molding machine, a cold chamber injection molding machine performs the melting process in a cold chamber.
The working principle of a cold chamber injection molding machine is as follows:
- Mold preparation: The first step is mold preparation. The mold should have a pre-designed shape.
- Preparation of plastic granules: The plastic granules are placed in a special hopper.
- Melting process: The granules from the hopper are transported to the melting zone. In this zone, the granules melt slowly. The melting process takes place in a cold chamber.
- Injection process: The melted plastic is injected into the mold. In a cold chamber injection molding machine, the plastic is not affected by the temperature of the mold as it melts. This minimizes the stress built up in the plastic and ensures better quality results.
- Cooling process: After the injection process is complete, the mold is moved to the cooling zone. Here, the mold allows the plastic part to cool.
- Part extraction: After the mold has cooled completely, it is removed from the mold. The plastic part can be easily removed from the mold.
Cold chamber injection molding machine, can result in a longer production time of the plastic part due to the mold remaining cold. However, this type of machine is ideal for the production of precise, complex parts, resulting in higher quality results.
