Seamless Equipment Integration: Designed with standardized mounting interfaces, the mold allows for rapid installation and alignment within major industrial low-pressure casting machines, reducing setup downtime.
Tackling a 21-ton, ultra-large complex mold requires a foundation of predictive engineering. We emphasize upfront Design for Manufacturability (DFM) combined with advanced Computer-Aided Engineering (CAE) mold flow analysis. By meticulously simulating the pouring system and molten metal flow dynamics, we proactively identify and eliminate forming risks before cutting a single piece of steel. This guarantees that the massive dimensions of the battery housing achieve exact structural strength and dimensional precision.
Comprehensive CAE fluid and thermal simulation to eliminate cold shuts and misruns.
Intelligent gating design tailored specifically for large-surface-area aluminum flow.
Rigorous stress-testing of the 21-ton mold structure to ensure longevity under high clamping forces.
New energy battery housings feature expansive surface areas and thin walls, making heat dissipation during the casting process a monumental challenge. To combat this, our mold incorporates a highly sophisticated composite "Water + Air" cooling system. This precise thermal balancing acts quickly to extract heat from critical zones, effectively shortening the molding cycle while preventing common casting defects.
Dual-media cooling (water and air) for targeted temperature control across different mold thicknesses.
Significant reduction in shrinkage porosity and thermal warping in the final cast part.
Dynamic thermal equilibrium maintenance, which directly extends the operational lifespan of the mold components.
Prevention of hot spots that could compromise the mechanical properties of the aluminum alloy.
The e-mobility sector places zero tolerance on moisture intrusion. Battery housings demand extreme high density and flawless airtightness. The Low Pressure Die Casting (LPDC) process is uniquely suited for this, utilizing a smooth, bottom-up filling mechanism under controlled pressure. This methodical filling prevents the turbulent mixing of air and molten metal, resulting in an exceptionally dense internal structure.
Achieves an ultra-low porosity rate of less than 1%, ensuring maximum structural density.
Guarantees exceptional hermetic sealing, passing the strictest waterproof and leak-proof tests.
Enhances the overall mechanical yield strength and elongation properties of the battery base under complex driving conditions.

Q: How does the dual water and air cooling system specifically improve the casting of such a large battery housing?
A: Large surface areas like the 1859x1440mm battery base are prone to uneven cooling, which causes warping and internal stress. Our dual system uses water channels for rapid heat extraction in thick-walled sections and air cooling for gentle temperature regulation in thinner, delicate areas. This precise thermal balance ensures uniform solidification, drastically reducing cycle times while preventing dimensional distortion.
Q: Can this LPDC mold accommodate different high-strength aluminum alloys required for EV lightweighting?
A: Yes, the mold is specifically engineered to handle advanced, high-fluidity aluminum alloys such as A356 and AlSi10Mg. The gating system and thermal management controls are calibrated to accommodate the specific melting points, shrinkage rates, and flow characteristics of these lightweight, high-strength materials, ensuring optimal mechanical properties in the final cast.
Q: What precise steps are taken to ensure the dimensional accuracy of a massive 21-ton mold?
A: Maintaining accuracy on a 21-ton block of steel requires extreme precision. We utilize heavy-duty, 5-axis CNC machining centers to cut the cavities with micron-level precision. Post-machining, the entire mold assembly undergoes rigorous CMM (Coordinate Measuring Machine) inspections to verify that every contour, mounting point, and cavity dimension aligns perfectly with the original CAD data.
Q: How does the low-pressure die casting process benefit the hermetic sealing of the battery base?
A: Traditional high-pressure casting can trap air, creating microscopic pores. LPDC forces molten aluminum upwards against gravity at a slow, controlled pressure. This laminar flow pushes air out ahead of the metal, resulting in a highly dense, non-porous microstructure (porosity <1%). This density is what guarantees the battery housing remains completely leak-proof and waterproof under severe conditions.
Q: What exactly is included in the full-process turnkey service for this tooling solution?
A: Our turnkey service is a complete, risk-free package. It begins with collaborative product design and CAE mold flow analysis to optimize the part. We then handle the complete mold design, CNC manufacturing, and assembly. Crucially, it includes in-house mold trials where we actually cast sample parts to prove the mold works flawlessly. You receive a fully validated, production-ready mold along with the optimized casting process parameters.
