Tungsten hot runner and nozzle

Short Description:


Product Detail

Product Tags

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 demolishing, and small deformation of parts. So many high quality products on the market are produced by hot runner molds.

Since tungsten-molybdenum and its alloy materials have high thermal conductivity, high-temperature strength, creep resistance, wear resistance, and high corrosion resistance, they are suitable materials for making hot runner nozzles in injection molding equipment such as injection molding machines.
