Hydraulic Tank Part

The hydraulic tank part's blank is cast using the sand casting lost foam vacuum casting process.

The white mold is pressed with a mold. 

We use high-strength raw materials to make the white mold.

Four layers of paint are applied to increase the mold's surface strength.

Molding sand is then filled for the reinforcement.

We finally use the vacuum casting process, the casting saturation has been improved to a great extent. 

The product is comprehensively processed by a five-axis machining center.

The accuracy of related dimensions can reach 0.02mm, and the machinable size is 1500mm.

We design a reasonable maching process to gain high accuracy of the hydraulic tank part. 

We manage to ensure multiple hole positions and sizes are processed in one clamping.

By this way, we reduce the accuracy error caused by multiple clampings.

First the datum plane of the bottom surface is machined.

Then the datum plane is used as the basis for positioning to perform other precision processing.

Shot blasting and sand blasting are carried out after casting.
