400T Cold Chamber Die Casting Machine Aluminum Alloy Office Chair Five-Prong Base Machine

Specialized in manufacturing lightweight, high-rigidity integrated aluminum alloy office chair five-prong bases, this 400-ton cold chamber die casting machine targets modern minimalist office furniture and ergonomic chair products. Modern office chairs pursue lightweight design for easy movement and transportation, while requiring sufficient structural strength to ensure user safety; traditional welded assembled bases have poor consistency and low strength. This equipment realizes one-piece thin-wall high-density forming of aluminum chair bases, reducing product weight without compromising load-bearing rigidity, perfectly matching the upgrading trend of modern lightweight office furniture.

Featuring a newly enhanced rigid frame design, paired with high-strength alloy tie bars, enlarged thickened anti-wear steel pins and extra-thick high-load platens, the machine delivers greatly improved overall rigidity and ultimate load-bearing capacity at 400 tons of clamping force. The high-stiffness structure minimizes thin-wall mold deformation and molten aluminum splashing during high-pressure forming, ensuring uniform thin-wall thickness and ultra-low internal porosity of chair bases. It achieves the perfect balance of lightweight appearance and high structural compactness, and supports long-term continuous production of high-standard lightweight furniture bases with extended equipment service life.

Equipped with an imported German PLC core and full-color HMI touchscreen, the machine supports real-time precise monitoring and dynamic adjustment of injection speed and pressure. Advanced closed-loop control technology enables ultra-fine graded adjustment of the injection process, ensuring fast, uniform filling of large-area thin-wall base legs and reinforcing rib structures, completely eliminating internal porosity and loose structures. It significantly improves surface flatness and structural compactness of finished lightweight chair bases, reducing subsequent trimming and polishing work. The optimized electrical circuit is simple and stable, adapting to high-temperature industrial production environments, and the intelligent fault display system quickly locates equipment faults to reduce production downtime.

The hydraulic system adopts dual-proportional intelligent control to achieve fast multi-stage thin-wall filling and low-pressure buffered mold clamping, balancing lightweight forming efficiency and mold protection. All hydraulic sealing components are imported from Europe and Japan, with excellent wear resistance, high temperature resistance and leak-proof performance, ensuring long-term stable hydraulic operation under 400-ton clamping force. The hydraulic die height adjustment system enables convenient, efficient mold installation and debugging, saving labor and time costs for lightweight chair base mold changeover. The automatic pressure relief energy-saving function reduces system operating load and invalid energy consumption for green, efficient lightweight part production.

The professional clamping and die height adjustment mechanism ensures uniform mold stress and stable positioning accuracy, preventing thin-wall base deformation and edge warping caused by high-pressure injection. The high-flow valve and precision piston accumulator injection device provides stable, adjustable injection speed and pressure, perfectly adapting to various streamlined lightweight five-star chair base mold designs. The built-in high-efficiency oil cooling system stabilizes hydraulic temperature and ensures consistent lightweight forming quality in long-term production. The equipment has a long service life of 15 to 20 years, and an optional mold sweeping robotic arm is available for automated production upgrade.
