raw material
The timber includes basswood/ashwood/marupa/CEDAW/kiri wood and other Yunnan white wood.
Manufacturing process
1. Purchase the plate (ROUGH SAWN TIMBER) and process it into blade/cover/lower rail.
2. After cutting and sanding - painting - punching - assembly
3. The coating process can be divided into STAIN and PAINTED. The European and Australian markets prefer STAIN treatment, while the American and Canadian markets have PAINTED accounting for 80%. All SATIN (N.C coating) refers to that after painting, the wood grain can still be seen, while PAINTED (covering color) is completely invisible.
4. General NC coating line process:
Feeding → feeding machine → two-sided colouring machine → force bone conveyor → head primer → force bone conveyor → second primer → force bone conveyor belt → material receiving (one bottom and one side) → the second primer shall be applied according to the same procedure. The total length of the equipment is about 75 meters.
Feeding → primer sander → skeleton conveyor belt → dust remover → finishing machine → skeleton wheel conveyor → finishing machine → skeleton conveyor → feeding (one side at a time) → making the second side according to the same procedure, with a total length of about 70 meters.
In case of PAINTED coating, it shall be applied 2-3 times more, and the paint coating is thick and not easy to dry.
In addition, UV coating has the advantage that the coating line is short and the UV drying speed is fast, but the paint and coating are expensive
