What is the die casting technology

Die casting process is a die casting factories of the technical level of the reflected, he can put the die casting machine characteristics, mould characteristics, casting characteristics, die-casting alloy characteristic factors of production such as TAG:LianTiaoShi oil case wrench ReZuo pieces semi-solid metal

  Die casting process is a die casting factories of the technical level of the reflected, its main effect is:
  1. He can put the die casting machine characteristics, mould characteristics, casting characteristics, die-casting alloy characteristic factors of production such as the right to combine up to the lowest cost, production to meet the requirement of customers die-casting products. The die casting technology engineer must attach importance to the selection and training. Die casting process engineer is the die casting technology is always in charge, in addition to formulate correct die casting process, according to production elements variation revised timely die casting technology outside, still is responsible for DiaoZhengGong, die casting die mounting operatives, training and improve the mold repair.
  2. To improve productivity, provisions each injection cycle cycle time. Low productivity is unfavorable to improve economic efficiency, high productivity often at the expense of the die life and casting percent of pass is the price, calculate general ledger details: may be more bad economy.
  3. To determine the correct die casting parameters. Assures casting meets the customer in quality standards, under the premise of should make injection speed, injection pressure, the lowest temperature alloy. So, which helps reduce machine, mould load, reduce faults, improve life. According to the characteristics of die casting machines, mould characteristics, casting characteristics, die casting aluminum alloy characteristic triangle, determine the quick shot speed, injection pressure, boosting pressure, slow injection schedule, quick shot schedule, with the distance, launched the punch trip, the holding time, pushing the reset the time, alloy temperature, mold temperature, etc.
  At the same time in the die casting technology should also pay attention to the following:
  1. Use water-based coating, must be rigid formulate detailed spraying process. The coating brand, coating and the proportion of water, die every parts of the spraying amount (or spraying time) and spraying order, compressed air pressure, spray gun and moulding surface distance, spraying direction and moulding surface Angle, etc.
  2. According to die casting die actual to determine the correct mold cooling scheme. The correct mold cooling scheme on production efficiency, casting quality, die life, have the enormous influence. Plan should provide for the cooling water accounts method, die casting die several times first cooling, between the several times to die time cooling water valve opening open to provisions. Some cooling system, cooling strength should by die casting technology engineer field the setting, with spraying to mold heat balance.
  3. The die casting process engineer must attach importance to the selection and training. Die casting process engineer is the die casting technology is always in charge, in addition to formulate correct die casting process, according to production elements variation revised timely die casting technology outside, still is responsible for DiaoZhengGong, die casting die mounting operatives, training and improve the mold repair.
