The advantages for Hot Runner Mold

 The hot runner mold refers to a mold that uses a heating device to keep the melt in the flow passage from solidifying at all times. Because it is shorter than the traditional mold shot cycle and saves raw materials, hot runner molds are widely used in various industrialized countries and regions in the world today.

Shorten cycle
The molding cycle is shortened. Because there is no restriction on the cooling time of the sprue system, the parts can be ejected in time after curing. Many thin-walled parts produced with hot runner molds have a molding cycle of less than 5 seconds.

Save material
In the pure hot runner mold, there is no cold runner, so there is no production material. This is especially significant for applications where plastics are expensive. In fact, the major hot runner manufacturers in the world have experienced rapid development in the world when oil and plastic materials are expensive. Because hot runner technology is an effective way to reduce material costs.

Reduce waste
Reduce waste and improve product quality. During the hot runner mold forming process, the plastic melt temperature is accurately controlled in the runner system. Plastics can flow into the cavities in a more uniform state, resulting in consistent quality parts. The hot runner molding parts have good gate quality, low residual stress after demolding, and small deformation of parts. Therefore, many high quality products on the market are produced by hot runner molds.

Production automation
Eliminating subsequent processes is conducive to production automation. There is no need to trim the gate and recycle the processed cold runner. It's conducive to production automation. Many foreign manufacturers have combined hot runners with automation to significantly increase production efficiency. Many advanced plastic molding processes have been developed based on hot runner technology.
