Low-pressure casting is a casting method in which liquid alloys are pressed into the mold cavity from bottom to top under pressure, and solidified under pressure to obtain low pressure die casting parts.
The casting formed by low-pressure casting has a dense structure, and it is easy to cast a thin-walled and complex casting, which is generally used for casting non-ferrous alloys. The metal recovery rate of the low-pressure casting process reaches 95%, which is pollution-free and easy to automate.
Low-pressure casting was first used in industrial production. Nowadays, low-pressure casting is mainly used to produce aluminum alloys and magnesium alloy parts, such as automobile wheel hubs in the automotive industry, cylinder blocks of internal combustion engines, cylinder heads, and other castings with complex shapes and high-quality requirements.
The production process of low-pressure die-casting automobile wheels includes the following basic processes:
● Metal smelting
● Preparation of low-pressure die-casting automotive wheel hub molds or LPDC wheel mold tools
● Preparation before pouring: including sealing test, mold matching, fastening low-pressure die-casting automobile wheel mold or mold, etc.
● Pouring: Liquid liter, filling, pressurization, solidification, pressure relief, cooling, etc.
● Demoulding: demoulding and taking out the casting
Using low-pressure die-casting automotive wheel molds to produce wheels has become the most common way of wheel manufacturing.
The LPDC wheel mold design is improved on the basis of gravity casting. The molten metal is pressed into the mold cavity and cooled by water or air cooling.
LPDC wheel mold tooling allows for more complex shapes, improved defects of gravity wheel tooling, better quality, and more reasonable prices.
1. LPDC wheel mold tool can accelerate the solidification speed of thick parts and eliminate casting defects.
2. Improve the casting performance of key parts.
3. Improve the yield rate and reduce the production cost.
4. High-quality LPDC wheel mold can save energy and reduce consumption.
5. LPDC wheel mold installation improves the productivity of your production line.
Low Pressure Die Casting Automotive Wheel Mold
Low-pressure cast hubs are common and high strength. Low-pressure cast wheels are safe as long as they are used within reasonable limits.
The low-pressure casting wheels are made of low-pressure casting aluminum automotive wheel molds. The entire production process of the low-pressure casting wheels is mechanized, and the process level is very stable.
The output and yield rate will be higher when using low-pressure cast aluminum automotive wheel molds compared to wheel manufacturers. This is the casting method chosen according to the actual situation of the wheel manufacturer, and there is essentially no difference in quality.
Superband mold has made outstanding contributions to Chinese aluminum wheel industry and has been rated as one of the top 20 die-casting mold manufacturers in China in terms of comprehensive strength.
