650T Cold Chamber Die Casting Machine Chair Bases Machine ADC12 Office Chair Leg

Specialized in manufacturing plating-grade aluminum executive chair bases for high-end office furniture and boardroom seating, this 650-ton cold chamber die casting machine targets the premium appearance and large-size demands of executive seating. Executive chair bases require flawless, pore-free surfaces to support polished chrome plating, brushed finishing or powder coating, plus generous leg dimensions and high load capacity to match large executive chair designs; surface pinholes, flow lines and subsurface porosity will directly ruin final appearance and increase polishing labor. This 650T equipment realizes large-size high-density forming of aluminum executive chair bases with smooth plating-ready surfaces, achieving premium appearance quality and robust structural performance in one casting step.

Featuring a newly enhanced ultra-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 load-bearing capacity at 650 tons of clamping force. The high-stiffness structure minimizes mold micro-vibration and molten aluminum splashing during high-pressure forming, ensuring uniform wall thickness and ultra-low surface porosity of large executive chair bases. It achieves the ideal combination of smooth plating-grade surface, generous dimensions and high structural compactness, and supports long-term continuous production of high-end office 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 smooth, uniform filling of large curved leg surfaces and rounded edges, completely eliminating surface pinholes, flow marks and subsurface porosity. It significantly improves plating adhesion and surface finish quality of finished executive chair bases, preventing coating blistering and surface defects in high-end furniture. 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 smooth multi-stage filling and low-pressure buffered mold clamping, balancing plating-surface quality and mold protection for large-size molds. 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 650-ton clamping force. The hydraulic die height adjustment system enables convenient, efficient mold installation and debugging, saving labor and time costs for executive chair base mold changeover. The automatic pressure relief energy-saving function reduces system operating load and invalid energy consumption for efficient high-end furniture production.

The professional clamping and die height adjustment mechanism ensures uniform mold stress and stable positioning accuracy across the large platen, preventing surface blemishes and edge flash caused by high-pressure injection. The high-flow valve and precision piston accumulator injection device provides stable, powerful injection speed and pressure, perfectly adapting to various large-size executive chair base mold designs. The built-in high-efficiency oil cooling system stabilizes hydraulic temperature and ensures consistent surface 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.
