  Operation method of plywood hot press

①Turn on the power of heat press to check whether the equipment parameters are within the specified range.②Put the hot-pressed product into the hot -pressing fixture to fix it, and do not touch the hot pressed aluminum plate with your hands to prevent burns.③Leave both hands out of the aluminum plate range of the hot press, check that there is no abnormal condition and press the hot press switch to press it down.④The heat pressure will rise automatically after the specified time. In case of abnormal situation, press the emergency switch quickly.⑤Do not put any debris on the top of the heat press or next to the switch to prevent danger.

   Precautions for hot pressing of plywood

①  Hot press time: there is 16-24% resin glue in the backstage of veneer dipping, polycondensation reaction occurs during the hot pressing curing process, which will release a lot of heat. The thickness of the product is too large, and the greater the heat released. Therefore, when the product thickness is greater than 25mm, press for 4 minutes/per/mm of product thickness. When the product thickness is less than 25mm, press for 5 minutes/per/mm of product thickness. The hot pressing time is calculated only when the unit pressure and the temperature of the hot pressing plate reach the specified value. ②Heat pressing temperature: hot pressing temperature during loading:40-50 degrees Celsius; hot pressing temperature:145-150 degrees Celsius; hot pressing temperature when slab unloading:40-50 degrees Celsius. ③The time required for the temperature of the board to rise to the  hot pressing temperature: when the product thickness is greater than 25mm,30-40 minutes; when the product thickness is less than 25mm:20 to 25 minutes.
