Carbon steel casting includes carbon as the main alloying element and a small amount of other elements. As the carbon content increases, the strength of cast steel increases and the hardness increases. Cast carbon steel has higher strength, plasticity, toughness, and lower cost, and is used in heavy machinery to manufacture parts that are subjected to heavy loads. Precision casting is the general term for obtaining precision-size castings. Compared to the traditional sand casting process, precision casting products are more precise in size and have a better surface finish. China precision casting is also called lost wax casting. Casting products are precise, complex, and close to the final shape of the parts, which can be used without processing or with little processing, so It is an advanced technology. 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), and this method is so popular with our customers. The quality is higher than water glass technics, and the cost is lower than silica sol technics. Carbon Steel Precision Casting divedes auto parts casting, Train Parts Casting, railway parts casting and mechanical precision casting. The main casting steel material is No.25 steel, No.35 steel, and No.45 steel.
