Introduction of die casting
PANDE provides total solution aluminium die casting service from 3D drawings to finished parts.
Aluminium pressure die casting is a casting method in which a liquid or semi-solid metal or alloy, or a liquid metal or alloy containing a reinforcing phase, is filled into the cavity of a die-cast type at a higher speed under high pressure and causes the metal or alloy to solidify under pressure to form a casting.
1. Advantages of pressure casting
1) High productivity, easy to mechanize and automate, can produce thin-walled castings with complex shapes. The minimum wall thickness of die-cast zinc alloy is only 0.3mm, the minimum wall thickness of die-cast aluminum alloy is about 0.5mm, and the minimum casting pore diameter is 0.7mm.
2) The casting size accuracy is high, and the surface roughness value is small. Die casting dimensional tolerance grades up to CT3 ~ CT6, surface roughness is generally Ra0.8 ~ 3.2 μm.
3) Die casting parts can be embedded in the casting parts, which not only saves valuable materials and machining man-hours, but also replaces the assembly process of the components, which can eliminate the assembly process and simplify the manufacturing process.
2. Disadvantages of pressure casting
1) When die casting, the liquid metal filling speed is high, the gas in the cavity is difficult to completely eliminate, the casting is prone to defects such as porosity and cracks and oxidation damage debris, and the die casting usually cannot be heat treated.
2) The structure of die-casting die-casting die is complex, the manufacturing cycle is long, the cost is high, and it is not suitable for the production of small batch castings.
3) The die casting machine has high cost and large investment, which is limited by the clamping force and the size of the die casting machine, and is not suitable for the production of large die castings.
4) The type of alloy is limited, zinc, magnesium, copper and other non-ferrous alloys.
Fields of application
Due to the advantages of die casting, it has been widely used, mainly used in mass-produced non-ferroalloy castings. In the output of die castings, the largest proportion is aluminum alloy die castings, which are 30% to 50%; followed by zinc alloy die castings; copper alloy die castings account for 1% to 2%. The most used die casting parts are the automobile and tractor manufacturing industries, followed by instrument manufacturing and electronic instrument industry, and then agricultural machinery, national defense industry, computer, medical equipment and other manufacturing industries. Parts produced by die casting include engine cylinder blocks, cylinder heads, transmission boxes, engine covers, housings and brackets for instruments and cameras, pipe fittings, gears, etc.
