The introduction of lathe bed casting

The introduction of lathe bed casting.
Casting is one of our main products, today I will introduce the knowledge of lathe bed casting:
The advantages of using the resin sand mould to cast machine tool lathe bed casting. The resin sand mould has good stiffness. The high strength of casting sand in pouring early is conditional to use graphitization expansion in the cast iron solidification process to effectively eliminate shrinkage, shrinkage defects and realize the less riser, no riser casting of ray cast iron andnodular iron casting.
Solid mold casting production uses polystyrene foam plastic shape used feed resin self-hardening sand molding.When the liquid metal is poured into the mold,foam plastic shape repidly gasifies,burns and disappears under the effect of high temperature metal liquid.The molten metal takes place of the position of the foam and cools solidification into the same type and shape solid type casting.
Respectively Speaking,lost foam casting has bigger advantage for the large mold, such as production of single or small batch automobile covering parts and machine tool lathe bed than traditional sand mold, that not only saves the expensive wood type,but also it has the advantage of convenience of operation, shortage of the production cycle, improving the production efficiency and high dimensional precision, small machining allowance and good surface quality. In addition, the casting machine has better wear resistance,shock resistance and good process performance.
We are with zero defect management concept all the way. At the same time,we continue to perfect the service system and care about your every needs in pursuit of perfect quality. you have need for our products, please visit our company or contact us for enquiry.
