138T Hot Chamber Die Casting Machine Car Key Shell Diecast Machine Car Key Fob

Purpose-built for manufacturing original equipment zinc alloy car key fob housings with strict automotive-grade dimensional tolerances, this 138-ton hot chamber die casting machine delivers exceptional part consistency and precise mating performance, making it an ideal production solution for automotive Tier 1 suppliers and OEM key system manufacturers.

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, effectively minimizing mechanical vibration and mold deflection. For car key housing production, this translates to consistently accurate internal snap-fit dimensions, precise mounting hole positions and uniform wall thickness across every production batch, ensuring seamless automated assembly and reliable long-term performance of finished key fobs.

At its control core is a genuine German PLC system paired with a full-color human-machine interface touch screen, enabling precise real-time monitoring and adjustable control over injection speed and injection pressure. Advanced closed-loop control technology enables ultra-fine regulation of injection speed throughout the entire filling cycle, ensuring complete, uniform formation of intricate internal features and tight dimensional tolerances required by automotive specifications. The control panel also features a built-in fault display function that quickly indicates electrical system abnormalities, helping operators resolve issues efficiently and minimize downtime, even in sustained high-temperature production environments.

The hydraulic system operates on dual-proportional control architecture to realize fully programmable multi-stage injection and low-pressure mold clamping, which protects precision mold cores and delicate snap-fit features from impact damage and extends tooling service life. All hydraulic seals are sourced from premium European or Japanese brands to ensure long-term reliable, leak-free operation. The machine is fitted with a hydraulic die height adjustment system, making mold installation and changeover faster and more convenient to save time and labor for multi-model key housing production runs. It is also equipped with an automatic pressure relief energy-saving function that effectively reduces system energy consumption during operation and minimizes unnecessary energy loss.

The clamping and die height adjustment mechanism ensures uniform stress distribution and stable mold positioning, while the injection unit with high-flow valves and a precision piston accumulator delivers accurate, consistent injection performance that adapts to various car key housing mold designs. A high-efficiency oil cooling system maintains stable hydraulic temperature during extended production runs, supporting an overall service life of 15 to 20 years. An optional mold sweeping robotic arm is available for further automation upgrade.
