Molding technology of hot runner precision mold factory

The hot runner is a part of the runner, which refers to the use of heating or heat preservation to keep the rubber in the gate always in a fluid state. Due to the injection of the gate after the rubber is cooled and solidified, it becomes recycled waste. It can be seen that the two are the most advantageous The hot runner forming mold saves raw materials, especially for the high price of raw materials, which can reduce the cost the most. Now you turn your attention to improving the accuracy of hot runner molding products, light, thin, short, small electronic and electrical parts are very important. Here we introduce hot runner precision molding technology and expand its application range.

Two: maintain temperature conditions

Maintaining a constant mold temperature and injection temperature for injection molding is a prerequisite for maintaining dimensional accuracy, especially for hot runner molding, where high temperature molten resin is in a low temperature mold, and it is more difficult to maintain mold temperature. This is an important issue in order to realize the precision forming of the hot runner.

1. Control the temperature to maintain that the athlete is still liquid natural rubber material without curing, the rubber temperature has a low limit, low pressure filling. But the actual work is usually to increase the temperature of the material. If the rubber temperature range is too wide, the molding shrinkage will be uneven, that is, the main work of controlling the temperature.
