138T Zinc Alloy Die Casting Machine 3D Embossed Medal Diecast Machine Sports

Built for producing thick-wall, 3D-styled and irregularly shaped zinc alloy sports medals and commemorative awards that demand dense internal structure and consistent mechanical strength, this 138-ton hot chamber die casting machine delivers powerful, stable injection performance to ensure complete filling and void-free formation of heavy, complex medal geometries.

The machine adopts a newly reinforced frame structure, together with high-strength tie bars, enlarged steel pins and thickened machine platens, greatly improving overall rigidity and load-bearing capacity. This heavy-duty structural design gives the machine stronger impact resistance and better load stability during high-pressure die casting, which is essential for producing thick, robust 3D medals that require high injection pressure and dense internal structure. The design reduces mechanical deformation, extends the machine’s service life to 15–20 years and makes it especially suitable for heavy-duty continuous production of complex sports awards.

Control is handled by a German PLC system with an intuitive color touch screen HMI that provides precise real-time monitoring and adjustment of injection speed and pressure parameters. Closed-loop control technology ensures accurate, repeatable injection speed regulation and optimized packing pressure, resulting in fully dense, void-free medal castings with consistent weight and uniform internal structure, eliminating shrinkage defects common in thick-wall zinc alloy parts. The built-in fault display function allows quick diagnosis of electrical system issues, minimizing downtime and supporting uninterrupted production for bulk custom medal orders, even in high-temperature environments.

The dual-proportional hydraulic system delivers smooth multi-stage injection and controlled low-pressure mold clamping, and is fitted exclusively with high-quality European or Japanese oil seals for dependable, low-maintenance operation during long continuous production runs. The hydraulic die height adjustment system makes mold installation and adjustment fast and convenient, saving time and labor for factories producing multiple sizes of thick-wall medals. An automatic pressure relief energy-saving function effectively reduces system energy consumption during operation.

The clamping and die height adjustment mechanism ensures uniform stress distribution across the mold and highly stable mold positioning, while the injection unit with high-flow valves and a precision piston accumulator delivers strong, consistent shot performance that fully fills thick-wall and irregular medal geometries without porosity or cold shuts. A high-efficiency oil cooling system maintains stable hydraulic temperature during extended production shifts for consistent part quality. An optional mold sweeping robotic arm is available for customers seeking to automate their medal production lines.
