88T Hot Chamber Die Casting Machine for Precision Zinc Alloy Watch Bezel

88T Hot Chamber Die Casting Machine for Precision Zinc Alloy Watch Bezel Production

Purpose-built for manufacturing precision zinc alloy watch bezels for analog watches, dive watches and fashion timepieces, this 88-ton hot chamber die casting machine delivers accurate forming of circular bezel frames, engraved scale markers and inner crystal-seating grooves. Watch bezels require perfectly circular geometry, consistent scale marker positioning, flat crystal-seating surfaces and accurate inner diameter tolerance to ensure proper crystal fitment, smooth rotating action and precise time-marking alignment; any ovality, scale distortion or surface defect will compromise watch accuracy and premium appearance. This 88T equipment realizes one-piece high-precision forming of zinc alloy watch bezel frames, scale markers and crystal seats, ensuring every finished bezel meets tight dimensional and cosmetic standards.

The machine adopts a reinforced medium-tonnage frame structure equipped with high-strength tie bars, enlarged wear-resistant steel pins and thickened machine platens engineered for stable 88-ton clamping force. This rigid architecture delivers exceptional vibration resistance and load stability during high-speed hot chamber die casting, minimizing mold micro-jitter during precision forming of circular watch bezels. For zinc alloy watch bezel production, it guarantees consistent circularity, uniform scale marker depth and accurate crystal-seat flatness across every production cycle. The robust construction suppresses long-term mechanical deformation, extends equipment service life and fully supports non-stop high-volume production of small precision zinc alloy watch components.

At its control core is a genuine German PLC system paired with a full-color human-machine interface touchscreen, enabling real-time precise monitoring and adjustable control of injection speed and pressure. Advanced closed-loop control technology delivers fine graded regulation throughout the entire filling cycle, ensuring complete, clean formation of thin bezel frames, raised scale markers and inner crystal-seat grooves without cold shuts, flash or burr defects. This guarantees smooth rotating action, accurate scale alignment and reliable crystal seating for every zinc alloy watch bezel. The simplified electrical circuit design maintains stable, reliable operation even in high-temperature workshop environments, and the built-in fault display function quickly identifies electrical system abnormalities to minimize unplanned downtime.

The hydraulic system operates on dual-proportional control architecture to realize fully programmable multi-stage injection and low-pressure buffered mold clamping, which protects delicate scale-marker cavities and crystal-seat mold surfaces from impact damage. All hydraulic seals are sourced from premium European or Japanese brands, ensuring long-term leak-free, stable performance under continuous 88-ton operation. A hydraulic die height adjustment system enables fast, labor-saving mold installation and changeover, reducing setup time for different watch bezel sizes and scale designs. An automatic pressure relief energy-saving function effectively cuts unnecessary hydraulic energy consumption during continuous operation.

The clamping and die height adjustment mechanism ensures uniform stress distribution across the platen and stable mold positioning, avoiding bezel ovality, scale distortion and crystal-seat warpage. The injection unit with high-flow valves and a precision piston accumulator delivers consistent injection performance that fully fills precision circular watch bezel mold designs. A high-efficiency oil cooling system maintains stable hydraulic temperature during long-shift production, supporting a reliable service life of 15 to 20 years. An optional mold sweeping robotic arm is available to upgrade production automation.
