138T Zinc Alloy Die Casting Machine for Commemorative Medal Zamak Sports Medal Machine

 

As a highly versatile production solution for medal manufacturers with diverse product portfolios, this 138-ton hot chamber die casting machine covers the complete range of zinc alloy medal production: marathon medals, ball game awards, cycling event souvenirs, school sports medals and various custom commemorative awards. It is the ideal all-in-one machine for factories that need flexible production capacity across multiple product lines and frequent design changeovers.

The machine adopts a newly reinforced frame structure, paired with high-strength tie bars, enlarged steel pins and thickened machine platens, which greatly improves overall rigidity and load-bearing capacity. This robust structural design delivers stronger impact resistance and better load stability during high-pressure die casting, ensuring consistent forming quality across all medal types from thin decorative awards to heavy 3D commemorative medals. The heavy-duty construction reduces mechanical deformation over time and supports a service life of 15 to 20 years under normal industrial production conditions.

Equipped with a genuine German PLC system and intuitive color human-machine interface touch screen, the machine provides precise, repeatable monitoring and control over injection speed and pressure for every medal category. Closed-loop control technology enables flexible, on-the-fly adjustment of injection parameters, allowing quick and seamless changeover between marathon, ball game and commemorative medal production without sacrificing casting quality or process stability. The control panel features a built-in fault display function that quickly indicates electrical system abnormalities, helping operators identify and resolve issues efficiently to minimize downtime, with reliable performance even in high-temperature workshop environments.

The dual-proportional hydraulic system achieves fully programmable multi-stage injection and low-pressure mold clamping, and is fitted with high-quality European or Japanese oil seals for long-lasting, leak-free reliability. The hydraulic die height adjustment system makes mold installation and changeover fast and convenient, saving valuable setup time and labor when switching between different medal styles. An automatic pressure relief energy-saving function effectively reduces system energy consumption during operation and minimizes unnecessary energy loss.

The clamping and die height adjustment mechanism ensures even stress distribution and accurate mold positioning regardless of mold size, while the injection unit with high-flow valves and a precision piston accumulator adapts seamlessly to different mold designs, gating layouts and part geometries across all sports medal categories. A high-efficiency oil cooling system maintains stable hydraulic temperature during extended production runs for consistent part quality. An optional mold sweeping robotic arm is available for customers looking to upgrade to automated production cells.
