Why choose hot runner?

1. shorten the cycle

The molding cycle of the part is shortened. Because there is no limitation of the cooling time of the runner system, the part can be ejected in time after it is formed and solidified. Many thin-walled parts produced with hot runner molds can have a molding cycle of less than 5 seconds

2.save plastic

There is no cold runner in the pure hot runner mold, so there is no production cost. This is especially important for applications where plastics are expensive. In fact, the major hot runner manufacturers in the world have achieved rapid development in the era of expensive oil and plastic raw materials in the world. Because hot runner technology is an effective way to reduce material cost and material cost

3.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. Plastic flows more uniformly into the cavities, resulting in consistent quality parts. The gate quality of the parts formed by the hot runner is good, the residual stress after demolding is low, and the deformation of the parts is small.

4.Production automation

Elimination of subsequent processes is conducive to production automation. The finished product is the finished product after being formed by the hot runner mold, and there is no need to trim the gate and recycle and process the cold runner. Conducive to production automation. Many foreign product manufacturers have combined hot runner and automation to greatly improve production efficiency. Many advanced plastic molding processes are developed on the basis of hot runner technology. Such as PET preforming, multi-color co-injection in the mold, multi-material co-injection process, STACK MOLD, etc.
