Die casting process knowledge summary

In die casting process, thermosetting resin material to join a single material cavity, often called materials trough, and then forced into one or more closed modules in polymerization (curing). TAG:belt filter wrench buckle type oil case wrench Die casting machine

  Die casting process is will die casting machine, die casting die and alloy three elements organically and make a comprehensive process, and the metal mold casting by filling process, and is will pressure, speed, temperature and time get unified process technology factors. At the same time in the die casting technology, thermosetting resin material to join a single material cavity, often called materials trough, and then forced into one or more closed modules in polymerization (curing), here is simply introduce the:
  Material way, also called note way and flow, material flow from materials trough cavity, into the cavity before or after fault current limiter gate. A lot of the cavity with a single material slots. The air is in material cavity of material replacement, and through a special place vent discharge. When the material feeding trough into when in a compact measurement device feed measurement, and then preheat to nearly the polymerization temperature. A only add enough of an injection quantity.
  After the raw material of the material to preheat slot force again will be sent to a note feeder, this note device installed in material notch in immediately, in order to prevent from the piston and materials trough the gaps between the leakage of the material. Usually will seal to the collection into note to further prevent leakage feeder.
Feeding trough, note bar, gate, port and the cavity surface maintain can make the raw material of curing temperature must be quickly, according to the material properties, mould design and drawing of geometric shapes the temperature of 280 ~ 380 ° F.
  In die casting objects to curing period's end, will this time complete die-casting, conduct patterns, including removal from the gate, port, note way and material formed in the curing material cushion tank (called residual material). In die casting, preheat material is very important. Cold material flows slowly, first into the cavity of the material has not been to the end, namely may polymerization. If has the condition, the poor quality of the products, not only is the appearance, also reflected in mechanical properties. Some exceptions, such as injection times is very little, or some low viscosity materials. Can be used a heating lamp or stove heating, but effective and commonly used method is to use designed for plastic molding making dielectric heater.
  Above is my share with you about ReZuo a knowledge, we want to have the problems people help, our main production related components, welcome interested parties to choose.
