88T Hot Chamber Diecast Machine Zinc Alloy Bluetooth Earbud Shell Diecast

Tailored for manufacturing high-strength zinc alloy TWS earbud charging case shells with precision internal slots, hinge mounts and positioning features, this 88-ton hot chamber die casting machine delivers exceptional internal structure forming accuracy and consistent mechanical strength, making it ideal for premium earbud case products that demand reliable drop resistance, stable hinge function and precise internal component assembly.

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 reducing mechanical deformation and maintaining consistent mold clamping precision over long production runs. For earbud case shell production, this stable clamping performance translates to uniformly dense internal structure, accurately formed snap slots and hinge mounting positions, and consistent wall thickness that ensures reliable drop resistance and long-term opening/closing durability of the finished charging case.

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, clean formation of small internal ribs, snap features and mounting bosses without cold shuts or dimensional drift. This guarantees consistent assembly fit between the case shell and internal battery, circuit board and magnet components, reducing assembly rejection rates significantly. 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.

The hydraulic system operates on dual-proportional control architecture to realize fully programmable multi-stage injection and low-pressure mold clamping, which protects delicate internal core pins and small mold inserts from impact damage and extends mold service life. All hydraulic seals are sourced from premium European or Japanese brands to ensure long-term reliable, leak-free operation even under sustained high-pressure production conditions. 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 earbud case production. It is also equipped with an automatic pressure relief energy-saving function that effectively reduces system energy consumption during operation and lowers per-unit production costs.

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 fully fills complex internal feature geometries without porosity or shrinkage defects. A high-efficiency oil cooling system maintains stable hydraulic temperature and consistent oil viscosity 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 as production volume scales.
