Plywood Cold Bonding Line for Plywood Production
Plywood cold bonding line, is the necessary step for making plywood board. With glue machine /glue spreader for coating glue on veneer surface, then workers using these glued veneer to form the sandwish plywood panel according to the required plywood size and thickness. Then will convey the formed plywood panel into cold press machine, to pre-press glued veneer plywood through suitable pressure, make inside plywood veneer stick together.
For Glue spreader, its working way very simple, it includes four rollers, two pieces are rubber roller, for coating glue; another two pieces are steel rod, mainly for squeeze glue, help rubber roller to spreading glue on veneer surface.
After start glue spreader, put the veneer on the entrance between two rubber rollers, it will automatically convey and through the rubber roller, thus the veneer surface will be coated with balance glue.
So worker will form them into sandwich plywood panel through lay out pieces of veneers according to the required plywood thickness and size.
After lay out them, convey the panel into cold press machine, start the cold press machine, it will press the panel, press time not fixed. some clients set press time 30mins, some 1 hour, some longer time. The cold press machine function for pre-press glued panel. Usually for pre press machine, its pressure can be 400ton, 500ton, 600ton, will be poplar and enough. and for the standard plywood size 1250*2500mm, the cold press table size will be standard too. But if your plywood size smaller or bigger, we can customize the cold press to suitable for your plywood size.
Some our clients not use cold press machine, directly convey the glued veneer into hot press machine. Actually we advise use cold press machine, thus it can convey the plywood easily to hot press machine, and the hot press machine pressing time will be shorter and plywood quality will be better.
For making plywood board, we can offer you the full line of plywood machinery, from the beginning to processing raw materials wood, to the end product, our factory produce and offer the full sets. Like the veneer production machines, Veneer drying, Veneer sewing machine, Glue coating machine, Plywood hot press machine, Film hot press machine for film faced plywood, sanding machine and calibrating machine and other related machines.

Peeling is the pre-treatment process. Chopping and planing are both aimed at obtaining specific forms of wood materials, but the forms and application scenarios are different.
Shipping multiple containers of gluing equipment to multiple countries in a single batch is a testament not only to our current order fulfillment capacity but, more importantly, to the international market’s trust in the quality and reliability of the ‘MINGHUNG’ brand.
In Caoxian County, Shandong—a significant hub for China's wood-based panel industry—a crucial collaboration was finalized in 2017. Leveraging its professional expertise, Shandong Minghung successfully delivered a turnkey project for Shandong Longsen Wood Industry Co., Ltd. (Longsen Wood): a high-quality particleboard production line with an annual capacity of 150,000 cubic meters. This achievement marked a major leap forward for Longsen Wood and vividly showcased Minghung's strength in the field of complete equipment manufacturing for panel production lines.
