88T Precision Hot Chamber Die Casting Machine Zamak 3 5 Earphone Housing Diecast Machine

Engineered specifically for producing thin-wall, lightweight zinc alloy TWS earbud charging case housings with internal rib structures and compact fitting features, this 88-ton hot chamber die casting machine delivers exceptional mold filling capability, ensuring complete, uniform formation of thin walls and fine internal details without cold shuts or incomplete fill.

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, maintaining accurate mold alignment even under fast, high-pressure injection conditions required for thin-wall parts. For thin earbud case shells, this precise alignment is critical for preventing flash in thin gaps, ensuring uniform wall thickness and maintaining consistent structural strength across every part.

It is equipped with an advanced German PLC control system and a high-resolution color touch screen, which allows operators to precisely monitor and control injection speed and pressure throughout the casting cycle. Closed-loop control technology enables ultra-precise multi-stage adjustment of injection speed, ensuring fast, smooth filling of thin-wall sections and fine internal ribs while avoiding excessive flash or part deformation. The integrated fault display function on the control panel rapidly identifies electrical system abnormalities, helping operators resolve problems efficiently and maintain uninterrupted production.

The hydraulic system uses dual-proportional control to achieve multi-stage injection and low-pressure mold clamping, which protects delicate thin-wall core pins and fine internal mold inserts from damage. High-quality European or Japanese oil seals are used throughout the hydraulic circuit for long-lasting, reliable sealing performance even under high-pressure operating conditions. The hydraulic die height adjustment system enables fast, convenient mold installation and adjustment, saving setup time when switching between different earbud case models. An automatic pressure relief energy-saving function effectively reduces energy consumption during operation.

The clamping and die height adjustment mechanism ensures even stress distribution and highly accurate mold positioning, while the injection unit with high-flow valves and a precision piston accumulator delivers fast, steady injection performance suitable for various thin-wall earbud case mold designs. A high-efficiency oil cooling system maintains stable operating temperature and consistent hydraulic oil viscosity for reliable filling performance, and the machine is engineered for a service life of 15 to 20 years. An optional mold sweeping robotic arm is available as an automation upgrade.
