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.

What are aluminum die-casting alloy products? What characteristics do they have?

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:

• Good fluidity in the case of liquid;
• There are relatively fixed melting points and freezing points;
• Small shrinkage rate;
• Have a certain high temperature compressive strength;
• With excellent production and processing characteristics and corrosion resistance.

What are the key components of die-casting aluminum alloys? What are the residue components?

• The key ingredients are: aluminum, silicon, copper, magnesium, manganese, zinc, etc.
• Residue components are: iron, zinc, copper, tin, aluminum, sulfur, phosphorus and so on.
• Different aluminum alloy models have different regulations on key components and residue components.

What are the key disadvantages of castings?

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.

How much is the temperature of the aluminum alloy profile liquid suitable for aluminum die casting production?

Generally 650℃~720℃

What are the key parts of the aluminum die casting machine?

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.

What are the tons of aluminum die casting machines named?

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.

What is the function of the combined structure of the aluminum die casting machine?

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.

How much is the pound level of the hydraulic transmission system of the aluminum die casting machine?

Generally 12MPa (or 120kg/cubic centimeter).

What is the function of injection tissue?

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.
