Aluminum casting mold manufacturing follows standardized complete processes, covering design, processing, assembly and trial-test to ensure consistent mold quality.
The whole manufacturing process includes 6 core steps: design review, precision machining, mold assembly, trial test, comprehensive inspection and packaging delivery.
Design review stage completes 3D modeling and Procast CAE simulation, optimizing structure to control casting mold porosity shrinkage below 0.8%.
Precision machining adopts CNC and gantry equipment, controlling overall mold dimensional tolerance within ±0.03mm.
Mold assembly stage completes cavity, cooling and exhaust system fitting with assembly accuracy controlled within 0.02mm.
Casting mold trial-test conducts 3–4 batch pouring verification to confirm stable forming of aluminum castings.
Comprehensive inspection uses CMM and 3D laser scanner to verify full-size and surface quality compliance.
Packaging delivery adopts professional anti-rust packaging with complete technical documents for export transportation.
LPDC casting mold, gravity casting mold and CPC counter-pressure casting mold all adopt this unified standardized process flow.
Aluminum wheel mold and EV structural part mold adjust partial process parameters according to structural complexity.
Full in-house processing without outsourcing ensures 100% process controllability and stable delivery cycle.
Standardized process control improves mold qualification rate to 99.2%, far exceeding the industry average of 95%.
Standardized manufacturing process is the core guarantee for stable quality of aluminum casting molds. All customized LPDC casting mold, gravity casting mold and CPC counter-pressure casting mold follow unified six-step production specification. The design stage relies on UG/CATIA 3D modeling and professional Procast CAE simulation to eliminate casting mold porosity shrinkage and structural defects in advance. Precision CNC and gantry machining equipment ensure high-precision molding of mold cavity and cooling channels. Strict assembly accuracy control ensures the coordination of cooling, exhaust and locking structures. Multiple batches of casting mold trial-test verify the actual production performance of the mold to avoid unqualified products entering the market. CMM coordinate measuring machines and 3D laser scanners complete full-size precision detection to ensure dimensional compliance. The final standardized packaging and document delivery meet international export standards. For complex-structured EV structural part mold and high-precision aluminum wheel mold, targeted parameter optimization is carried out on the basis of unified processes. Full in-house production mode avoids quality differences caused by outsourcing processing, realizes full-process quality controllability, and significantly improves mold qualification rate and delivery stability, providing reliable mold products for global aluminum alloy foundries.
