Art, making the core is based on the requirements of the casting process, in good shape determining method 150kn bollard, molding materials prepared on the basis of well conducted. Economic effect precision castings and all production processes, depending on which procedure. In many modern foundry, casting, making the core are realized mechanization or automation. Commonly used sand molding core equipment of high, medium and low pressure molding machine, air impact molding machines, flaskless shoot squeeze molding machine, cold box core and hot box core machine, coated sand core making machine. Since the casting mold in cooling pouring out, with a gate, riser, metal burrs, Phi slit, sand casting sand casting also adhesion, it must be clean processes. Such work equipment grinder, shot blasting machine, pouring riser cutting machines. Sand casting off the sand clean-up is a process of poor working conditions bollard, so the choice modeling method, should be taken into account to create convenient conditions for the sand clean. Some castings for special requirements, but also after the casting process, such as heat treatment, shaping, anti-rust treatment, roughing, etc. . After pouring the cooled casting from the mold is removed, a gate, riser and metal burrs Phi slit, sand casting sand casting also adhesion, it must be clean processes. Such work equipment shot blasting machine, gate riser cutting machines. Sand casting off the sand clean-up is a process of poor working conditions, so the bollard 150kn in the choice of modeling methods, should be taken into account to create convenient conditions for the sand clean. Some castings for special requirements, but also after the casting process, such as heat treatment, shaping, anti-rust treatment, roughing, etc. Casting is more economic methods of rough shape 750kn bollard, the shape of complex parts can show its economy. Such as automotive engine blocks and heads, ship propellers and exquisite works of art. Somewhat difficult to cut parts, such as gas turbine parts nickel-based alloy can not be formed without casting method. 250kn bollard | Chen Hua Machinery (certified) | bollard provided by the China Machinery Equipment Co., Ltd.
