Hot runner molds are widely used in various industrialized countries and regions around the world today. This is mainly because the hot runner mold has the following significant characteristics:

Forming cycle

Due to the lack of cooling time limitations in the runner system, the parts can be ejected in a timely manner after forming and curing. Many thin-walled parts produced using hot runner molds can have a forming cycle of less than 5 seconds.

Saving plastic raw materials

In pure hot runner molds, there is no production waste due to the absence of a cold runner. This is particularly significant for expensive plastic application projects. In fact, the major international hot runner manufacturers have achieved rapid development in the era of high prices for petroleum and plastic raw materials in the world. Because hot runner technology is an effective way to reduce material costs and reduce material costs.

Improve product quality

During the hot runner mold forming process, the temperature of the plastic melt is accurately controlled in the runner system. Plastic can flow into each mold cavity in a more uniform and consistent state, resulting in parts of consistent quality. The parts formed by hot runner have good gate quality, low residual stress after demolding, and small deformation of the parts. So many high-quality products in the market are produced by hot runner molds. Many plastic parts in familiar MOTOROLA phones, HP printers, and DELL laptops are made using hot runner molds.

Beneficial for production automation

The finished product is formed by a hot runner mold, without the need for trimming gates or recycling cold runners. Beneficial for production automation. Many foreign product manufacturers combine hot runner with automation to significantly improve production efficiency.

Expand application scope

Many advanced plastic forming processes have been developed based on hot runner technology. For example, PET pre molding production, multi color co injection in molds, multi material co injection process, STACK MOLD, etc.
