Cold runner

The company "Rosplast" produces molds with cold runner and hot runner systems.

Cold runner system in the process of casting is not exposed to heating. After completion of the intake cools down and falls (which can happen when you open a form, and after).

The most significant advantage cold runner system are:

- Low cost
- Ease of maintenance
- High reliability

However, it should be noted that currently, the ratio of mass plastic gate and mass production. When large numbers of small-scale mass production plastic gate can match or even exceed their mass. When a big weight plastic gate productivity decreases due to the increase of time casting. Also, a lack of cold runner system is constantly combo gate.

When designing cold runner systems specialists are closely related to its balance and indicators to improve the productivity of the installation.
