Precision Casting For Automobile

 Precision Casting for Automobile has a good content of carbon, so it is easy to casting, especially A216 WCB. Silicon and manganese can be added in amounts greater than those required strictly to meet these criteria so that arbitrary upper limits for these elements have to be set, usually, 0.60% for silicon and 1.65% for manganese are accepted as the limits for Auto Parts Castings.  In wax pattern process, we mix stearic acid and paraffin wax. In wax pattern making, as you know, it is better than polyethylene, and the wax deformation is small. In dipping slurry process,most of the suppliers adopt water glass technics in domestic area, but we adopt compound technics or silica sol technics. As you know, carbon steel castings will be much smoother with compound technics (compound of water glass and silica sol technics), this method is so popular with our customers, and the quality is higher than water glass technics, the cost is lower than silica sol technics.  In shell making, we adopt automatic sand-covering production line, which was invented under the guidance of our general manager. The indoor temperature was controlled by air-conditions, keeping the temperature at  24℃±1℃, which can make the castings much more stable,the internal tissues much more well-proportioned.  Our Automobile Parts Castings have quality assurance in accordance with ISO9001: 2008, strict material inspection and exact dimension control
