Working pressure forging is commonly known as aluminum die casting. Aluminum die casting is the whole process of using abrasive tools and mechanical equipment to quickly fill the die with metal material liquid under working pressure, changing from liquid to solid, and producing the necessary products.
From the injection chamber method, it can be divided into hot chamber aluminum die casting (common for zinc alloy materials) and cold chamber aluminum die casting (common for aluminum alloy profiles), and can be divided into: low pressure casting (such as car wheel shell) and working pressure forging (such as All companies use working pressure forging), from the exhaust pipe method is divided into: general aluminum die-casting and vacuum pump aluminum die-casting.
Common suitable raw materials for aluminum die-casting are: zinc alloy material, aluminum alloy profile, die-casting aluminum and alloy copper. They have the following characteristics:
Generally speaking, there are under-casting (unsatisfactory material), cracks, deformation, cold insulation, cold streaks, shrinkage, air vents (sand holes), mechanical equipment contusion, stick mold contusion, layers, misplaced molds, welding bumps, surface air pockets, blistering, succulents, lack of meat, etc.
Generally 650℃~720℃
The aluminum die-casting machine is mainly composed of a composite structure, an injection structure, an ejection structure, a driving force (hydraulic machine) system software, an automatic control system, an air intake system, and a refrigeration system.
The tonnage of the aluminum die-casting machine is named after the larger clamping force (clamping force). For example, the 180T aluminum die-casting machine has a larger clamping force of 180 tons.
The function of the joint structure is to install the fixed abrasive and push a part of the movable die of the die casting mold to eject or lock the mold.
Generally 12MPa (or 120kg/cubic centimeter).
The injection structure is an important part of the casting process, so that the metal material liquid is filled into the mold cavity of the abrasive tool from the injection chamber at a certain rate and working pressure.
