88T Hot Chamber Die Casting Machine for Durable Zinc Alloy Sports Medal

88T Hot Chamber Die Casting Machine for Durable Zinc Alloy Sports Medal Manufacturing

Engineered specifically for producing durable zinc alloy sports medals for marathons, running races, triathlons and school athletic events, this 88-ton hot chamber die casting machine focuses on robust structural forming and consistent relief detail for event award programs. Sports medals must withstand bulk production, include a ribbon attachment loop, reproduce event logos and course details clearly, and maintain a premium finish for award ceremony presentation; inconsistent relief detail or weak attachment loops will compromise event quality and participant satisfaction. This 88T equipment produces high-density, well-finished zinc alloy sports medals with reinforced ribbon loops and crisp event artwork, supporting race organizers in delivering memorable finisher awards.

Robust Structural Design

Built on an upgraded medium-tonnage integral frame matched with high-strength tie bars, precision steel positioning pins and thickened load-bearing platens, the machine delivers outstanding overall rigidity and anti-vibration stability at 88 tons of clamping force. This high-stiffness structure suppresses equipment vibration and mold micro-jitter during high-pressure injection, preventing relief detail blur and ribbon-loop weakness in sports medals. It ensures consistent relief depth, uniform medal thickness and reliable ribbon-loop strength across every zinc alloy sports medal, perfectly meeting the demands of bulk race award production.

Advanced Digital Control System

Equipped with an imported German PLC programmable control system and high-definition color HMI touchscreen, the machine realizes visualized digital control of full-process injection speed and pressure. Advanced closed-loop speed regulation technology performs ultra-fine adjustment of molten zinc filling speed, ensuring smooth, steady filling of event artwork, course map details and ribbon-loop structures without surface defects. The optimized electrical circuit simplifies complex control logic, maintaining stable operation in high-temperature industrial environments. The real-time fault display function quickly locates equipment anomalies, ensuring uninterrupted production of high-quality sports medals.

Efficient Hydraulic System

The hydraulic system adopts mature dual-proportional control technology to achieve flexible multi-stage variable-speed injection and gentle low-pressure mold clamping. It effectively protects fine relief mold cavities and ribbon-loop core pins from impact damage. The entire hydraulic circuit uses premium European and Japanese imported oil seals, ensuring long-term leak-free operation with stable pressure output. The flexible hydraulic die height adjustment system simplifies mold installation and debugging, saving time and labor costs for multi-event sports medal production. The automatic pressure relief energy-saving system intelligently optimizes hydraulic operating pressure to reduce unnecessary energy loss.

Precision Clamping and Injection

The uniform-stress clamping mechanism and precise die height adjustment device ensure stable mold locking force and accurate mold positioning, effectively eliminating edge flash, thickness inconsistency and ribbon-loop deformation in sports medals. The high-flow valve and precision piston accumulator injection system delivers balanced, steady injection volume, adapting to various round, rectangular and custom-shaped sports medal mold designs. Matched with an efficient oil cooling system, the machine maintains long-term stable hydraulic performance and consistent forming quality, with a durable service life of 15 to 20 years. Customers can optionally add a mold sweeping robotic arm for semi-automated production.
