First, wooden shutters
A. Raw materials: Wood has BASSWOOD (椴木) / ASH WOOD / MARUPA / CEDAR / KIRI WOOD (paulownia) and other Yunnan white wood.
B. Process:
1. Purchase the sheet (ROUGH SAWN TIMBER) and cut it into blades/covers/lower rails.
2. After cutting sanding - painting lacquering - punching - assembly
3. The painting process can be divided into two types: STAIN and PAINTED. Among them, the European/Australian market prefers STAIN processing, and the US and Canada market PAINTED accounts for 80%. All SATIN (NC coating) means that the wood grain can still be seen after painting, and PAINTED ( Cover color) The wood grain is not visible at all.
4. General NC coating line process:
Feeding→feeding machine→double-sided coloring machine→force bone conveyor→head primer→force bone conveyor→second degree primer→force bone conveyor belt→ receiving material (one bottom side)
→ Make a second primer according to the same procedure. The total length of the equipment is about 75 meters.
Feeding→primer sanding machine→force bone conveyor belt→dust removal machine→finishing machine→force bone type rounding machine→
Topcoat machine→force bone conveyor→feeding (once side)
→ According to the same procedure, the second side, the total length of the equipment is about 70 meters.
For the cover color (PAINTED) coating sequence must be 2-3 times more, and the paint coating is thicker and not easy to dry.
Another UV coating, the advantage is that the coating line is shorter, because the UV drying speed is faster, but the paint is more expensive.
C. Note:
1. Due to the different wood used, different wood grain is produced, the coloring coating is difficult to change, and the color is difficult to grasp. Generally, the range of deep/medium light is provided for customer confirmation when proofing, and the same blade must be cut and retained. accurate.
2. It is necessary to pay attention to the uniform sanding of the blades, especially the sides of the blades are not easy to sand, resulting in rough sides.
3. Pay attention to the thickness of the blade and the number of blades of the finished product to prevent the factory from cutting corners.
4. Humidity is especially important and should not exceed 12 degrees to prevent blade deformation.
5. Blade punching should not be broken or punched with burrs.
6. When the whole window is worn, from top to bottom, the color is light/medium/deep in order, especially the middle part of the whole window is important.
7. The whole window must pay attention to the flatness of each blade. There must be no bending deformation or banana shape. The OVERLAPPING condition should be checked on both the front and the back.
Double Servo Pipe Cutting Machine
The double servo Pipe Cutting Machine is adopted. The accuracy of the length of the pipe cutting is guaranteed to be within ± 0.05mm (the error is mainly generated on the steel pipe and tool), and the cut luster is free of rough edge.
