88T Hot Chamber Die Casting Machine for Precision Embossed Zinc Alloy Medal

88T Hot Chamber Die Casting Machine for Precision Embossed Zinc Alloy Medal Production

Purpose-built for manufacturing precision embossed zinc alloy medals for corporate awards, school honors and event commemorations, this 88-ton hot chamber die casting machine delivers accurate forming of raised relief designs, engraved text fields and medal border structures. Medals require crisp, sharp relief detail, perfectly flat back surfaces and consistent edge finishing to faithfully reproduce logos, names and decorative motifs; any detail blur, dimensional distortion or surface defect will undermine the prestige and perceived value of the award. This 88T equipment realizes one-piece high-precision forming of zinc alloy medal bodies, relief designs and attachment loops, ensuring every finished medal meets the detail fidelity and surface quality expected by award and event organizers.

The machine adopts a reinforced medium-tonnage frame structure equipped with high-strength tie bars, enlarged wear-resistant steel pins and thickened machine platens engineered for stable 88-ton clamping force. This rigid architecture delivers exceptional vibration resistance and load stability during high-speed hot chamber die casting, minimizing mold micro-jitter during precision forming of medal relief designs. For zinc alloy medal production, it guarantees consistent relief depth, uniform edge thickness and accurate attachment-loop 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-sized zinc alloy award items.

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, clean formation of fine relief patterns, engraved text areas and medal border details without cold shuts, flash or burr defects. This guarantees crisp detail reproduction and smooth surface quality for every zinc alloy medal. 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 delicate relief mold inserts and fine-texture cavities from impact damage. All hydraulic seals are sourced from premium European or Japanese brands, ensuring long-term leak-free, stable performance under continuous 88-ton operation. A hydraulic die height adjustment system enables fast, labor-saving mold installation and changeover, reducing setup time for different medal designs and event types. 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 platen and stable mold positioning, avoiding relief distortion and edge inconsistency in zinc alloy medals. The injection unit with high-flow valves and a precision piston accumulator delivers consistent injection performance that fully fills complex relief-detail medal molds. 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.
