1、Use wood with a low moisture content for the frame, typically 10-12%, or slightly higher.
2. The edge panels of the door are made of five-ply or three-ply wood.
3. Calcium chloride can be added to the plywood adhesive as a setting accelerator. Generally, prolonged drying of the adhesive can affect subsequent processes. If the adhesive dries too quickly, it may become brittle and detach. Therefore, the drying time should be controlled to be at least 4 hours, with a maximum of 24 hours.
4、Cold pressing typically uses equipment with a lead screw for batch pressing, with pressure levels often controlled based on experience. The goal is to ensure that the adhesive flows evenly around the edges of the panel.
5. After cold pressing, allow it to sit for approximately one day, then scrape and sand the edges.
6. Of course, achieving a desirable door panel finish requires further design work, which is separate from the application of adhesive.
Note: The application of ready-mixed putty paste for assembling wooden doors is typically a part of the process for manufacturing composite doors. The information provided is sourced from the internet; specific usage and quantities should be determined based on professional manufacturing methods.
