400T Cold Chamber Die Casting Machine for Die-Cast Aluminum Stock Pot & Casserole Stew Pot Production

Purpose-built for manufacturing die-cast aluminum stock pots, casserole stew pots and Dutch ovens for household and commercial kitchen use, this 400-ton cold chamber die casting machine delivers stable, high-precision forming of deep-wall aluminum cookware with uniform wall thickness and integrated thick-base heat-distribution structures. Aluminum stew pots require perfectly round body geometry, consistent wall thickness for even heat retention, flat sealing rims for lid fitment, and smooth interior surfaces ready for non-stick or ceramic coating; any ovality, warpage, porosity or dimensional inconsistency will directly affect lid sealing, cooking performance and coating quality. This 400T equipment realizes one-piece high-pressure forming of deep aluminum pot bodies, thickened induction-compatible bases and dual side-handle mounting bosses, ensuring every finished die-cast aluminum casserole pot meets consistent functional and quality standards.

The machine adopts a heavy-duty reinforced frame structure equipped with high-strength tie bars, enlarged wear-resistant steel pins and extra-thick machine platens engineered for stable 400-ton clamping force. This rigid architecture delivers exceptional impact resistance and load stability during high-pressure cold chamber die casting, minimizing mold deflection and micro-vibration during precision forming of deep-draw pot bodies. For aluminum stock pot production, it guarantees consistent roundness, uniform wall thickness, flat rim sealing surfaces and accurate handle-boss positioning across every production cycle. The robust construction suppresses long-term mechanical deformation, extends equipment service life and fully supports non-stop high-volume production of medium-to-large aluminum cookware vessels.

At its control core is a genuine German PLC system paired with a full-color human-machine interface touchscreen, enabling real-time precise monitoring and adjustable control of injection speed and pressure. Advanced closed-loop control technology delivers fine graded regulation throughout the entire filling cycle, ensuring complete, smooth formation of deep pot interiors, thickened heat-distribution bases and dual handle mounting structures without cold shuts, porosity or flow marks. This guarantees reliable cooking-surface quality, stable lid-rim flatness and consistent non-stick coating adhesion for every die-cast aluminum stew pot. The simplified electrical circuit design maintains stable, reliable operation even in high-temperature workshop environments, and the built-in fault display function quickly identifies electrical system abnormalities to minimize unplanned downtime.

The hydraulic system operates on dual-proportional control architecture to realize fully programmable multi-stage injection and low-pressure buffered mold clamping, which protects deep-draw pot mold cavities, side-core mechanisms and precision core inserts from impact damage during cookware production. All hydraulic seals are sourced from premium European or Japanese brands, ensuring long-term leak-free, stable performance under continuous 400-ton operation. A hydraulic die height adjustment system enables fast, labor-saving mold installation and changeover, reducing setup time for different stock pot capacities and casserole pot styles. An automatic pressure relief energy-saving function effectively cuts unnecessary hydraulic energy consumption during continuous operation.

The clamping and die height adjustment mechanism ensures uniform stress distribution across the large platen and stable mold positioning, avoiding pot-body ovality, rim warpage and base flatness deviation in aluminum stew pots. The injection unit with high-flow valves and a precision piston accumulator delivers powerful, consistent injection performance that fully fills deep-wall pot body molds with complex thick-base structures. A high-efficiency oil cooling system maintains stable hydraulic temperature during long-shift production, supporting a reliable service life of 15 to 20 years. An optional mold sweeping robotic arm is available to upgrade production automation.
