Hot Chamber Die Casting Machine for Lightweight Zinc Alloy Fashion Jewelry

Specialized in manufacturing lightweight, high-strength zinc alloy fashion jewelry accessory clasps including pendant bails, scarf rings and bracelet connectors, this 25-ton hot chamber die casting machine targets the performance demands of modern fashion jewelry. Fashion accessory clasps must be lightweight to ensure wearing comfort while retaining sufficient clamping strength and structural toughness to avoid cracking, bending or slipping during daily use. This 25T equipment realizes thin-wall integrated high-density forming of zinc alloy jewelry clasps, cutting component weight without sacrificing functional rigidity and durability, perfectly matching the upgrading trend of lightweight fashion jewelry hardware.

Featuring a newly enhanced rigid compact frame design paired with high-strength alloy tie bars, enlarged thickened anti-wear steel pins and thickened high-load platens, the machine delivers greatly improved overall rigidity and load-bearing capacity at 25 tons of clamping force. The high-stiffness structure minimizes thin-wall mold deformation and molten zinc splashing during high-pressure forming, ensuring uniform thin-wall thickness and ultra-low internal porosity of jewelry accessory clasps. It achieves the ideal balance of lightweight profile and high structural compactness, and supports long-term continuous production of high-standard fashion jewelry parts 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 thin-wall clasp bodies and internal reinforcing structures, completely eliminating internal porosity and loose structures. It significantly improves structural toughness and clamping strength of finished lightweight accessory clasps, preventing fracture and deformation under daily wearing stress. 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 25-ton clamping force. The hydraulic die height adjustment system enables convenient, efficient mold installation and debugging, saving labor and time costs for lightweight jewelry clasp 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 clasp 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 hollow-out lightweight fashion jewelry clasp 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.
