Fine point gate nozzle mold common point gate, point gate nozzle for fine mold. When the appearance of the gate does not allow a clear traces of products is relatively large, the structure is more complex gate usually point the way into the plastic. Advantages: automatic gates and products at the top of the separation process; selecting gate location is more flexible, small gate mark; small stress generated gate premises. Cons: not easy to process the gate; in two plate mold mold can not be used in this way; requires the use of a larger injection pressure. Elongated plate-shaped retaining ring when the height dimension larger abs, if conventional retaining ring abs-170, the greater the length of the gate bushing, causes during the injection molding sprue through the shunt path length is large, the pressure losses. Therefore, you should consider using a mold shaped retaining ring lengthened. Cooling system cooling system is to control the mold temperature. Mold temperature has an impact on shaping the quality and efficiency of plastic molding, when the high mold temperature, molten plastic material flow better, help quickly filled cavity, to obtain high-quality products. But the temperature is too high plastic material curing time lengthened, while the top of the process is easily deformed. When the mold temperature is low, liquidity will deteriorate the plastic material, the material is difficult to fill the mold cavity abs-141, leading to increased stress, poor surface gloss molded articles, prone to crazing and weld marks and other defects . To understand the mold temperature is too high and too low to the product's pros and cons, the only reasonably be seen mold temperature in order to ensure product quality stability. Different plastic materials with different techniques, appearance requirements and structure of each product is different, in order to be able to produce products that meet the quality requirements of the products in the shortest period, the mold temperature is very important. The more stable mold temperature, the higher the quality of its size and appearance after injection products. abs-131 | Jieyang abs | Gary Paffett trade provided by the Shenzhen Municipal Trade Limited.
