Hot Chamber Die Casting Machine Car Key Shell Machine Zamak 3 5 Car Key Fob Housing Die Casting Machine

As a highly versatile production solution for automotive key manufacturers with diverse product portfolios, this 138-ton hot chamber die casting machine covers the complete range of zinc alloy car key housing production for sedans, SUVs, new energy vehicles and commercial vehicles. It is the ideal all-in-one machine for key system suppliers that need flexible production capacity across multiple vehicle models 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 key housing types from compact smart key fobs to traditional flip key shells. 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 key housing model. Closed-loop control technology enables flexible, on-the-fly adjustment of injection parameters, allowing quick and seamless changeover between different vehicle model key housing 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 key housing 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 car key housing 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.
