In addition, the cooling effect of traditional high-pressure spot coolers is not good, leading to increased costs.
A heating box and drive system are added to the high-pressure cooling machine. The drive motor drives the rotation of the drive shaft and rod, and the kinetic energy is converted into electrical energy by the conduction column and heating wire. The cooling water temperature is kept constant at 20°C, and the thick wall area of the product is directly cooled through the core cooling box.
It improves the yield rate and core life of high-pressure die-casting products, reduces production costs, and ensures temperature stability and internal quality of products during the die-casting process.
