Finishing Service for Your Die Cast Blanks
We offer CNC machining of die castings as a specialized service. We do not produce the die castings themselves. You supply the die cast blanks. We do the precision finishing. Die castings have good surface finish and high production efficiency. But the dimensional accuracy from the die casting process is often not enough for assembly. The critical areas like holes, sealing surfaces, and mounting faces need further machining. That is where we come in. We take your die cast blanks and machine them to your drawing requirements.

Accurate Finishing of Critical Features
The dimensional tolerance for die castings under 500 millimeters is plus or minus 0.01 millimeters. The center distance tolerance is also plus or minus 0.01 millimeters. For die castings over 500 millimeters, the tolerance is plus or minus 0.02 millimeters. The center distance tolerance is also plus or minus 0.02 millimeters. The fit surfaces have a roughness of Ra 1.6 micrometers or less. The general machined surfaces are held to Ra 3.2 micrometers or less. We machine sealing surfaces, mounting faces, and threaded holes to your specifications.

Experience with Aluminum Die Castings
We have extensive experience with common die casting materials like ADC12 and A380. These aluminum alloys machine well. But they have specific challenges. Die castings often contain internal porosity. We adjust the cutting parameters to avoid pulling out the porous surface layer. Die castings also have thin walls. We control the clamping force to prevent distortion. These are lessons we have learned through years of practice. We apply this knowledge to every job.
Clean Parts and Good Finish
We remove all burrs and break sharp edges. Thread holes are chamfered. The parts are cleaned and washed. There are no metal chips or sharp edges on the finished parts. We inspect every batch before shipping. Critical dimensions are measured one by one. We take photos for our records. We support third-party inspection. Our warranty is 6 months. The minimum order quantity is 1 piece.
