Description
Overview
New vacuum glass laminating oven with 4 working layers, for laminated safety glass, including bent laminated glass.
Maximum glass size: 2,800 x 6,000 mm (110 x 236 in) per layer.
Bent glass: maximum curvature (arc height) 360 mm (14.2 in); maximum glass thickness 36 mm (1.4 in).
Production capacity: about 201 m² (2,164 sq ft) per furnace load, in about 3 hours.
Two independent processing systems (Area A and Area B, 2 layers each).
Voltage and frequency are built to the buyer's requirement.
Specifications
Rated power: 136 kW
Net weight: 6,300 kg (13,889 lb)
Five-stage temperature control; temperature difference held within 3 to 5 °C (5 to 9 °F)
4 thermocouples
Heating Furnace
Nickel-chrome stainless steel heating tubes, set closer together near the door
Four power regulators working independently, with temperature compensation; the front 8 heating tubes and the rear 6 heating tubes of each area are on separate regulators
Turbo blowers circulate hot air through the furnace for even heating
50 mm (2 in) rock wool insulation board; seamless welded heating-insulation shell
Frame of 8 mm (0.3 in) angle steel, CO2-shielded welding, electrostatic spray finish; galvanized inner liner with insulation between the inner and outer walls
Heating cuts off automatically when the furnace body exceeds 180 °C (356 °F)
Control
Double Siemens PLC control systems with vacuum control
Siemens 10 in touch screen, multiple languages
Panasonic digital vacuum meters and voltage meter
Memory for 10 parameter sets; power-off memory
Adjustable vacuum degree; real-time display of vacuum pressure and temperature
Timed start, timed shutdown and automatic door opening
Alarm messages that name the cause
Piano-style control cabinet with a cabinet cooling fan; the vacuum pumps sit in a separate pump cabinet, away from the electrical parts
Vacuum System
2 vacuum pumps, each with a vacuum buffer tank that holds the vacuum through a power cut; rated for 24-hour continuous work
One vacuum line and one digital vacuum meter per silicone bag
Each line is monitored in real time: a leaking bag is cut off automatically and the other bags keep their vacuum
Power protection, oil and water separation, pressure-relief alarm and pump maintenance reminder
Silicone Bags
4 vacuum silicone bags, 3 mm (0.12 in) silicone, rated to 300 °C (572 °F)
Tear-resistant and aging-resistant, with Teflon mesh to protect the bags
Lifting Platform and Cooling
Automatic lifting platform, double scissor-fork structure, one-button lifting; lifts a full glass load without deformation
3 glass cooling tables with 3 industrial cooling fans (glass cooling station): fast cooling for better transparency
Scope of Supply
Heating furnace, control cabinet and vacuum pump cabinet
1 automatic lifting platform
4 vacuum silicone bags
2 vacuum pumps and 2 vacuum buffer tanks
4 stainless steel high-temperature trays with high-temperature bearings
4 circulating air motors
8 Teflon mesh sheets
3 glass cooling tables and 3 industrial cooling fans
Heavy-duty plug connectors between the control cabinet, the furnace and the lifting platform; all wiring in conduit
Packing
Plywood cases; ships in one 40 ft high-cube container (split design)
