Low Pressure Casting Compared to Gravity Casting
In low-pressure casting the method in which the metal is forced into the mould is the main difference/advantage over gravity casting and is absolutely controlled. As explained above it results in a low turbulence or turbulence-free mould filling with little to no corrosion.
The molten metal in the furnace is in a closed container under protected atmosphere. Because of this the metal absorbs less hydrogen and any other impurities as well as the oxide formation being greatly reduced. As opposed to gravity casting, the metal surface is not interrupted constantly since it is been forced from under the metal surface. What you get is a very clean quality metal.
◪ We not only have the traditional low-pressure casting technology, but also have the high strength and light weight manufacturing technology of "low-pressure casting + spinning". We always maintain various advanced technology advantages in aluminum alloy wheel manufacturing to meet customers' needs and lead the industry development.
◪ The formula has perfect testing equipment, including material testing machine, hardness tester, solid aluminum alloy containing slag quantitative tester, X-ray diffractometer, bending fatigue tester, radial fatigue tester, biaxial fatigue tester, 13° impact tester, 30°/90° impact tester, salt spray test chamber, humidity and heat test chamber, etc., which can carry out the four major testing areas of wheels (dimensional testing, alloy material performance, reliability and safety, coating and We have formed a complete testing system from the incoming inspection of raw materials to the factory inspection of finished products, and our testing capabilities range from material and performance to dimensional and impact and fatigue testing, and then to the testing of the coating performance of finished wheels.
◪ The company has obtained a number of patents by virtue of its strong technical strength: Patent for a clean grinding table based on aluminum alloy wheels.
◪ The company has been focusing on quality, management and environmental protection, and has passed. ISO 9001:2015, IATF 16949, Germany KBA, Japan VIA association certification (laboratory certification).
