The development of the modern automobile industry, casting proposed new technical requirements, namely 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, burrs, the top of the other issues; die-casting mold temperature is too low will cause the product: filling is not full, the cavities , excessive contraction, cold profiling and other issues. Die casting temperature is die-important process parameters affect casting quality, affecting productivity, the impact of the casting cost. The company launched the "casting molds point cooler" can well control the temperature of the mold. Use "Die casting cold spot" can be completely avoided due to the cold tube blockage point frequently, resulting in huge human, material and financial losses.
