Advantages: 1, can produce parts of complex shape, especially for complex lumen blank; 2, wide adaptability, commonly used industrial metal materials can be cast, a few grams to several hundred tons; 3, a wide source of raw materials, low prices drag cable trough mold, such as scrap, scrap, chips; 5, widely used agricultural machinery 40% to 70%; 4, the shape and size of the part of the casting is very close to reducing the amount of three cutting grooves, are no cutting Machine 70% to 80% by weight of all castings. Disadvantages: 1, the mechanical performance than forged, such as organizing coarse deficit; 2, sand casting streamers groove pressing, single-piece, small batch production, high labor intensity; 3, casting quality is unstable, multi-process, influence factor complex, is easy to produce a number of drawbacks. Casting defects casting quality has a significant impact, therefore, for the selection of the cast alloy and casting methods to lay the foundation, we should start with the quality of the casting, and combined to form a casting major defects prevention. . After pouring the cooled casting from the mold is removed, a gate, riser and metal burrs Phi seam streamers groove, 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 choice modeling method, should be taken into account for the sand to create convenient conditions for clean-up. 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, 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. _ Chen Hua-slot machine (certified) _ streamers groove provided by the China Machinery Equipment Co., Ltd.
