Birch Plywood Advantage
1) Veneer cutting, the cutting methods can be quater cut or rotary cut. This process produce different grades of veneers for plywood production.
2) Veneer drying, the moisture content in the veneer is critical for bond strength of a plywood panel.
3) Glue spreading, glue are spreaded on the veneer evenly with a glue spreader. The thinner the better.
4) Billeting,billeting is a professional term in plywood production. It a system method to lay up the veneers based on plywood structure, thickness and
layer numbers.
5) Ageing,the billeted veneers are stacked for 15minutes before cold press. This process is called aging.
6) Could press(Pre-Press),Cold press is the first step to make the veneers into a flat board.The stack are usually 1meter high. Pressure 0.8-1.0 MPa.Pre-
press time 15-20 minute.
7) Hot press, Liquid glue has no bonding strength,the glue must be cured in order to get bond strength.The curing requires pressure and high
temperature.
8) Surface Laminating,this is the second time hot press of 2 times hot press. Even though its time and pressure is less than the 1st hot press.
