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

Engineered specifically for producing plating-grade zinc alloy car key shell bodies that require flawless surface quality for electroplating, spray painting and PVD coating processes, this 138-ton hot chamber die casting machine delivers defect-free casting surfaces that dramatically reduce polishing labor and improve final finishing yield for automotive key manufacturers.

The machine features a newly reinforced frame structure with high-strength tie bars, enlarged steel pins and thickened machine platens, delivering greatly improved overall rigidity and load-bearing performance. This high-strength structural design provides superior impact resistance and load stability during high-pressure die casting, minimizing machine vibration that could cause surface blemishes and flow marks on visible key shell surfaces. The stable casting platform ensures consistent surface quality batch after batch, which is critical for achieving uniform, high-quality plating and coating results on automotive key housings.

At its control core is a premium 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, effectively eliminating flow lines, cold shuts, gas pores and surface blemishes on exposed key shell surfaces. This results in smooth, defect-free cast surfaces that require minimal polishing before finishing, significantly reducing labor costs and improving overall production yield. The control panel also features a fault display function for fast troubleshooting and minimal production interruption, with reliable performance even in high-temperature working environments.

The hydraulic system operates on dual-proportional control architecture to realize fully programmable multi-stage injection and gentle low-pressure mold clamping, which protects highly polished mirror mold cavities from impact damage and preserves fine surface texture over extended production runs. All hydraulic seals are sourced from premium European or Japanese brands to ensure long-term reliable, leak-free operation with no risk of oil contamination that could ruin plating and coating quality. The hydraulic die height adjustment system enables fast, convenient mold setup, and an automatic pressure relief energy-saving function effectively reduces operational energy consumption.

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 optimized for plating-grade automotive key production. A high-efficiency oil cooling system maintains stable hydraulic temperature for consistent process performance, and the machine is engineered for a service life of 15 to 20 years. An optional mold sweeping robotic arm is available for further automation upgrade.
