Cylinder Block

Cylinder block
*Material: Vermicular cast iron RT400, RT420
*process technique: Sand faced iron mould casting process
*Body strength: ≥ 450Mpa
*Body's wall thickness: 4~6mm

*Advantages of sand faced iron mould casting process:
From above table we can see that the product's size has a good stability and a high precision; The compactness is good, the casting has a good self-compensated feeding during the solidification process, this improves the compactness effectively; The reliable is high, because the cooling speed is quickly, subcooled temperature is large, grain becomes tiny, the strength is enhanced, ensure that the product is more reliable; Such technique approaches to rigid cast, it fulfills self-compensated feeding effectively, increases the rate of finished products and reduces the cost.

*Advantages of vermicular cast iron we apply:
At the same productivity, the investment of green sand casting production line is 2~4 times higher than the sand faced iron mould casting process production line; The sand faced iron mould casting process apply with resin sand, the bulk sand treatment work is canceled, the depreciation cost decrease a lot; We use the vermicular iron RT400 instead of the grey iron HT250, the wall thickness of the casting is reduced from 6 mm to 4.5 mm, realizes the product's light weight, then materials are greatly reduced.
