 The detailed production process description of solid wood cabinet doors

Among the components of the overall cabinet, the door panel is equivalent to the face of the cabinet, and different styles and textures can be formed by changing the style, line type, color, material, and processing methods of the cabinet door. The natural texture and texture of the solid wood cabinet door, and the changeable shape, have always been loved by consumers. Today, I will take American cabinet doors as an example to show you the production process of solid wood cabinet doors.

The detailed production process description of solid wood cabinet doors

First of all, we have to understand the structure of solid wood cabinet doors. The production process of door panels of different structures is different. The solid wood door panels are generally framed in a four-in-one manner, that is, four frames plus a core board. Such a structure is firm and beautiful, but it is not so simple to produce. So what are the specific production process of solid wood cabinet doors?

1. Dry

The wood in general furniture factories is directly purchased from the market. After the wood is purchased, it must be dried first. After drying, the wood is not prone to deformation and cracking. Generally in the north, the moisture content of wood should be controlled at about 8-9%, and in the south it is about 10-12%.

4. finishing

1. Four-sided planing and shaping

Four-sided planing is used to process the board, which can be processed and shaped on all four sides of the board. After the four-sided planing process, the surface of the wood is smooth, flat, and the line is smooth and consistent. The width and thickness are all the net material size.

2. Saw cutting

Next, the length of the board should be fixed and cut. During the processing, there should be no chipping, blackening, internal cracking, the length and width error should not exceed 0.3mm, and the diagonal length difference of less than 1 meter should be ≤0.5mm, 1 Plates above meters should be ≤1mm.

3. Tenoning and drilling

The four-in-one solid wood door panels are all spliced ​​with a tenon and tenon structure, and it is necessary to open the door frame and mill the cross frame of the door panel.

4. Milling type

General manufacturers usually use a single vertical axis milling machine for milling. The milling of door frames and door cores can be completed on this. When processing door frames with curvature, molds are needed to help shape the shape.

5. Sanding

Sanding the inner groove of the door frame to prevent chipping and burrs during milling, which will affect the glue and paint of the later core board assembly.

6. Door core board processing

First, use a door core milling machine to process the door core plate. There are two milling cutters in the front and 2 sets of grinding wheels at the back. The door core plate is milled out of the edge, and then the milling part is sanded, and then along the side track Automatically wrap around and re-mill another face. The door core board after milling needs to be sanded and chamfered.

5. Assembling

1. Assembly

Because solid wood cabinet doors usually have a four-in-one structure, the four frames and the core board must be assembled, tenoning, glue coating, and rubber pellets placed. This is an extremely important procedure. After the assembly is completed, the cabinet door is basically shaped.

To meet the requirements of high precision, fast speed, and good quality of framing, high frequency framing equipment is a good choice. There are three reasons why it is said to be the key to making a door efficiently and effortlessly:
First, efficient framing is the key to improving efficiency. The high-frequency framing equipment can cure the glue in only 2-20 seconds, which can be streamlined;
Second, accurate frame assembly is the guarantee of quality. High-frequency frame assembly does not require gun nails and has high gluing strength. The equipment uses imported ball screws and precision linear guides, and is precisely controlled by a motor, resulting in high accuracy after assembly;
Third, convenient assembly is the liberation of manpower and material resources. The high-frequency frame equipment does not require manual frame assembly and proofreading, saving time and effort, convenient man-machine interface, and parameterized adjustment of assembly pressure, current, time, etc.

2. Adjustment after assembly

After assembly, the door panel needs to be grit sanded again by a fixed thickness sanding machine. Then through heavy-duty double-end milling, heavy-duty double-end milling is used for the square milling and size control of the solid wood door panel to ensure that the dimensional accuracy of the door panel is controlled within plus or minus 0.2mm.

6. finishing

The so-called "three-point carpentry, seven-point paint", the quality of the paint is very important to the quality of the product. When repairing the color, it is necessary to make the furniture show the main color while keeping the wood grain clear. The paint is not based on the thickness of the paint film, but the clear wood grain and thin film is the best.

Sanding is required before spraying.

The solid wood door panels are passed through a special-shaped sanding machine and a key sanding machine to improve the sanding quality. After that, the white billet grinding is continued, and the corners where the edges and corners are not in place are polished by hand.

Brush

After the wiping agent is prepared by a professional technician, you must first try to wipe it to confirm whether the wiping agent is correct and appropriate (adjust appropriately based on the color palette). Before wiping the color, stir the wiping agent evenly until there is no sediment. The brush used must be cleaned first, and the cloth strips to be wiped must be non-fading cloth strips. Brush the product evenly with a brush, and there should be no white leakage, and then quickly wipe the toner with a cloth strip. Check whether the product has any residual toner that has not been wiped clean, whether there is sagging, uneven coloring, etc.

Primer and sanding

Generally, medium and high-end solid wood cabinet doors need at least three primer spraying and three polishing procedures. Before spraying, blow the board dust clean, check whether the color wiping effect is good, and there should be no whitening and inadequate spraying during spraying. Polishing must first fill up all scratches, and polish off the burrs produced on the product after spraying. The background color cannot be sanded through. The sandpaper for sanding needs to be polished smoothly and evenly because of the coarse to fine sandpaper.
