Modern automotive industry development, casting techniques proposed new requirement that is lighter, thinner walls, complex shapes, in casting production in order to ensure the quality of the casting mold temperature control is also very important. The importance of die-casting mold temperature control: the die-casting mold temperature is too high will cause the product: thermal cracking, warping, surface pores, voids, flash, top of the other issues; die-casting mold temperature is too low will cause the product: not full filling, cavities excessive contraction, cold lines and other problems. Die casting die casting temperature is an important process parameters affect the casting quality, impact on productivity, the impact of the casting costs. The company launched the "casting molds point cooler" can well control the temperature of the mold. Using the "casting molds point cooler" to completely avoid cold tube blockage due to frequent point, causing huge human, material and financial losses.
