Machine tool castingsalso be calledheavy castings,the standard is GB9439-88, the material is HT200-300, it’s divided into sand mold casting and special casting. The machine tool castings’ production is that the metal mixture is heated to melt, so that it has the fluidity, and then poured into the mold cavity with a certain shape, under gravity or external force (Pressure, centrifugal force, electromagnetic force etc.) the mold cavity is full filled by the liquid, form the machine tool casting (parts) after the liquid is cooled and solidified.

Our company can design drawings and produce according to the customer requirements.

We can design and meet actual application drawings according to customers’ requirements.

Thelathe bedshould to be the annealing treatment which can reduce the hardness of metals and improve the plasticity and eliminate the residual stress to prevent the deformation and crack.
