850x1350mm vacuum laminating machine

6,000 N × 5 Fixed Multi-Cylinder Press — ~30,000 N Total Force Five AirTac cylinders simultaneously deliver 6,000 N each, distributing approximately 30,000 N of total press force uniformly across the 850 × 1,350 mm bonding area. Five-point pressure distribution at this scale is essential: any fewer contact points on a panel of this size would create pressure gradients that translate directly into adhesive thickness variation, uneven cure, and edge delamination defects in production.

Zone-Controlled Upper Platen Heating — ±2 °C Across 850 mm Width The upper platen heating is managed by zones (per the specification document: “upper platen heating by zones”), with Japan Omron temperature controllers maintaining ±2 °C uniformity across the full 850 × 1,350 mm bonding surface. Zone control allows independent compensation for heat loss at the edges and corners of a wide platen — a requirement that single-zone heating cannot meet at this scale. Lower platen heating is independently controlled for full dual-zone operation.

Three-Phase AC 380 V / 11.8 kW — Full-Scale Industrial Power Operating at 11.8 kW on three-phase AC 380 V provides the power headroom to drive the five-cylinder press system and dual-zone heating simultaneously at full rated capacity. Three-phase balanced load distribution eliminates the voltage instability risk that would affect heating precision and cylinder response under simultaneous high-load operation on single-phase circuits at this power level.

98 kPa Vacuum in ~25 Seconds The large sealed chamber evacuates to approximately -98 kPa in about 25 seconds. SMC digital negative-pressure gauge monitors chamber vacuum in real time; automatic alarm activates if the set vacuum level is not reached before the press cycle begins, blocking defective cycles caused by seal degradation or vacuum pump faults.

Vacuum-Optional Lamination Mode The specification document notes the lamination method as “Vacuum first and then laminating — Can be set without vacuum lamination.” This optional non-vacuum mode supports process development and testing scenarios where vacuum pull-down would damage fragile assemblies or where the adhesive system does not require vacuum assistance — providing process flexibility not common at this machine scale.

AirTac Precision Back-Pressure Regulation The back-pressure regulating valve provides controlled counter-force on all five cylinders as the platen descends, ensuring smooth, balanced contact with the display assembly surface across the full 850 mm width. This prevents sudden impact on large, thin-glass cover panels and enables controlled press speed adjustment to suit different adhesive systems.

40 mm Bonding Height Clearance The 40 mm clearance between the laminating platform and the fitting frame accommodates display assemblies including large-format backlight modules, framed industrial panels, and multi-layer wide-format display constructions.

Automatic Platform In/Out — 700 mm Ergonomic Work Height The laminating platform extends and retracts automatically under PLC control. The 700 mm work surface height — slightly lower than on mid-size models — is calibrated for comfortable standing operation when loading large, heavy panel assemblies that require two-person handling.

7-Inch PLC Touchscreen — Bilingual, Password-Protected The 7-inch colour touchscreen (Chinese/English switchable) provides access to all process parameters: vacuum time, aerate time, press time, decompression time, vacuum delay mode, and pressure-rise delay. Administrator password (9595) protects settings in multi-shift production environments.

Complete Industrial Safety Architecture Emergency stop button (immediate full-stop), buzzer alarm, leakage protection switch (CHINT automatic tripping), dual-button start interlock, optional safety grating (touch alarm, non-standard optional) — meeting standard industrial machinery safety requirements for heavy-load floor-standing production equipment.
