1600mm insulated glass hot press for double glazing

In modern double glazing production, the right hot press determines edge seal quality, flatness, and overall unit durability. Our range addresses different factory automation levels and budget requirements. The automatic 1600 insulating glass hot press machine handles loading, pressing, heating, and unloading with minimal operator input, making it ideal for high-output insulated glass lines. For heavy-duty applications that require stable force distribution, the hydraulic 1600 insulating glass hot press machine uses a four-cylinder hydraulic system to deliver even pressure along the entire 1600mm platen. The PLC controlled 1600 IG hot press machine offers recipe storage, touch screen operation, and precise temperature control for consistent double glazing and triple glazing units.

The 1600mm insulated glass hot press for double glazing is designed as a standalone hydraulic press that bonds two or three panes of glass with an aluminium or warm-edge spacer frame into a rigid, sealed insulating glass unit. It accommodates glass sheets up to 1600mm in width and 2200mm in length, with automatic platen gap adjustment for insulating glass thicknesses from 12mm to 60mm. The heating platens are made of high-grade steel with embedded electric heating elements and independent temperature zones. A PID temperature controller maintains the working surface between 30°C and 200°C with an accuracy of ±1.5°C, which prevents overheating of Low-E coatings and ensures butyl sealant flows evenly around the spacer. The hydraulic station uses a low-noise vane pump and a pressure relief valve, delivering adjustable press force from 5 to 16 metric tons. Four chrome-plated guide rods keep the upper platen parallel to the lower platen during movement, minimizing the risk of glass breakage or uneven sealant thickness. Operators program the press cycle through a PLC color touch screen, where they can set closing speed, pressing pressure, heating time, and cooling time. The control system supports multiple user levels and stores up to 100 production recipes for quick changeover between different product sizes.

The press cycle begins with manual or conveyor loading of the pre-assembled glass unit onto the lower platen. Once the operator confirms the recipe on the touch screen, the upper platen descends at a slow approach speed until it contacts the glass. The PLC then switches to high-pressure mode and maintains the set press force for the programmed dwell time. During this dwell period, the heating plates soften the primary butyl sealant and press the spacer frame into the sealant, eliminating air pockets and visual distortion. At the end of the dwell time, the hydraulic pressure is released, the platens separate, and the pressed unit is transferred to the sealing line. Below are the key technical parameters of the 1600mm insulated glass hot press for double glazing.

Standard equipment and functions include:

• Automatic platen heating with independent upper and lower temperature zones
• Hydraulic pressure holding function to maintain constant force during the dwell cycle
• PLC timer for pre-set heating and pressing time
• Automatic return stroke after completion of the press cycle
• Emergency stop buttons on both sides of the machine
• Oil temperature display and low-oil-level alarm
• Adjustable leveling feet and fixed anchor holes for installation

The hydraulic unit is separated from the heating zone to prevent thermal degradation of hydraulic oil, and the electrical cabinet is sealed to protect against dust and moisture. Routine maintenance is limited to checking the hydraulic oil level, cleaning the platen surfaces, and inspecting the guide rods every 500 operating hours. The machine can be customized with a top closing conveyor, automatic roller table, or vacuum lifter for integration into existing double glazing lines. Optional features include a barcode scanner for recipe recall, a temperature recorder for quality traceability, and a servo-controlled hydraulic pump for reduced energy consumption. The frame is powder-coated after shot blasting, and all electrical components comply with CE and ISO standards. These features allow the 1600mm insulated glass hot press for double glazing to maintain stable output in busy insulating glass workshops, producing flat, well-bonded units ready for secondary sealing.
