What are the advantages of Hot Runner Plastic Injection Mold?

Apr 23, 2018

Compared with the conventional molds, the molding cycle of the Hot Runner Plastic Injection Mold is relatively short, because it is a mold that mainly does not solidify the melt in the flow path by means of the heating device. At the same time, it saves more raw materials, so the hot runner injection mold has been widely used in industrialized countries and regions in the world today.

With the continuous promotion and application, the proportion of hot runner injection molds in the market continues to increase. Next, we will briefly introduce the main advantages for everyone, as follows:

1, shorten the cycle.

Can significantly shorten the molding cycle. Because it will not be limited by the cooling time of the runner system, the parts can be ejected in a timely manner after being cured. In fact, there are many thin-walled parts that can be produced using hot runner injection molds. The molding cycle can be controlled within five seconds.

2, save material.

This is because there is no cold sprue in the hot runner injection mold and no waste is generated. This is particularly significant for plastics expensive applications. Because hot runner technology is an effective way to reduce material costs and material costs.

3, reduce waste.

Reduce waste and increase product pass ratio. Normally, the plastic melt temperature is accurately controlled in the runner system during the hot runner injection molding process. Plastics can flow into the mold cavities in a more uniform state. The result is consistent parts. Hot runner molding parts have good quality, low residual stress after demoulding, and small part deformation. Because of this, there are many high-quality products that are produced from hot runner injection molds.

4, production automation.

The entire production process is simpler and more reasonable, providing favorable conditions for automated production. After the hot runner injection molding mold, the finished product will be the finished product without the need to trim the gate and recycle the cold runner.
