Quality Die Casting

Suitable for die castings with higher requirements on hole positions, assembly surfaces, threads, appearance and batch consistency.

Part stability can be controlled from die/mold design, die casting parameters, post-machining and surface treatment stages. According to the part application, inspection can cover porosity, shrinkage, flash, deformation and surface treatment defects.

CNC post-machining can improve the accuracy of mounting holes, sealing surfaces, positioning surfaces and assembly datum areas. These die castings are suitable for industrial equipment, automotive accessories, electronic housings, heat dissipation parts and structural parts orders.

For Quality Die Casting projects, die casting forming, post-machining and inspection standards should be controlled within the same project process. During the die/mold stage, the review should focus on the parting surface, gate, venting, cooling, ejection and post-machining datum. During die casting, the key points are filling condition, temperature, pressure, flash and deformation control. Post-machining inspection should cover hole positions, threads, sealing surfaces and assembly surfaces. For surface treatment, adhesion, color difference, scratches and masking positions need to be checked according to the part requirements.

The inspection focus should be adjusted according to different part structures. For housing pcs, inspection usually focuses on appearance surfaces, interface holes, screw bosses and internal assembly space. For bracket pcs, the main checks are mounting holes, load-bearing edges, flatness and reinforcing ribs. For heat dissipation parts, inspection should focus on the base plate, fins, thermal contact surface and post-machining datum.
