The features of hot runner mold
Jan 25, 2018


1. Shorten the molding cycle.

Because there is no cooling time limit of runner system, the molding can be cured in time.Many thin-walled parts made of hot runner molds can be formed in less than 5 seconds.

2. Save plastic materials.

There is no production cost in pure hot runner mold because there is no cold runner.This is especially important for the application of expensive plastics.In fact, the world's major manufacturers of hot runner have developed rapidly in the world of expensive oil and plastic materials.Because hot runner technology is an effective way to reduce the cost of materials.

3. Reduce waste products and improve product quality.

In the process of hot runner mould, the melt temperature of plastics is controlled accurately in the runner system.Plastic can flow into each cavity more evenly and uniformly, and the result is a uniform component.The parts of hot runner forming are of good quality, low residual stress and small deformation.Therefore, many high quality products in the market are produced by hot runner mold.Many of the plastic parts on the MOTOROLA phone, the HP printer, and DELL laptops are made with hot runner molds.

4. Eliminate the following process and facilitate production automation.

The finished product is finished by hot runner mold, no need to trim the gate and recycle and process cold runner.Conducive to production automation.Many foreign product manufacturers combine heat flow and automation to improve production efficiency greatly.

5.Expand the injection molding process application 

Many advanced plastic molding processes are developed on the basis of hot runner technology.Such as PET preforming, multi-color co-injection in MOLD, multi-material injection process, STACK MOLD, etc.
