A good chair production is inseparable from a team of professional technicians. We are a factory that has been engaged in carpentry making chairs for more than 20 years. We started from a small workshop of five to six people. After years of growth and training, we now cover an area of 20,000 square meters with a large team of more than 100 professional technical workers. There is more than 30 specialized equipment for automation and semi-automation. We uphold the concept of quality first, customers first, so that every chair we create is screened and strictly controlled, and cooperated by a professional logistics team, and finally delivered to customers in a safe and timely manner. Below we introduce the wooden cross back chair manufacturing process:
1. Cross back chairs material selection.
For cross back dining chairs, we have two different types of materials such as oak cross back chair and beech cross back chair, according to the actual requirements of customers. We prefer non-knotted and non-cracked materials, commonly known as aniseed materials. After we purchase an aniseed material, we cut and choose the material according to the size of our factory. Moreover, we directlypurchase the semi-finished material that has been cut and formed and buy it according to the specific size we provide to the supplier.
2. Cutting Process
We cut different plates into corresponding sizes to facilitatesubsequent processing into corresponding accessories. The long parts will be cut to make the back legs of the cross back chairs wedding. For particularly thin sheets, it will be processed into wooden cross-sections. Some particularly small wooden blocks will be placed on the four corners of the seat.
3. Preliminary machining
Preliminary machining focuses on the front and back legs and the prototype of the dock. The two important components of the cross back bentwood chair are the back legs and the back dock. We have strict production processes. Inside the machine, round rods are then produced for easy cooking and bending. The back part of the chair usually has two types of curved solid wood and solid wood.
4. High-temperature cooking
The process of making the camber of the wooden X back chair back leg and the dock of the wooden chair back is almost the same. It is necessary to cook at a high-temperature first to make the wood soft and suitable for the camber in a short time. Generally, the cooking time is more than 20 minutes.
5. Abrasive tool bending and drying
Our skilled workers will put the softened wooden stick on a special metal mold, fix it with metal locks according to the degree of curvature, and put it in the high-temperature kiln for approximately 72 hours so that it will not be easy after the wood becomes the required degree rebound.
The official launch of the terminal machine processing, sculpting, in line with the back of the human body. Wooden cross chair back dock. The machine is engraved at one time and the data collected by the CNC machine makes all the docks produced in the same size.
7. Seat plate processing and seat plate type
The thickness of the plate is 3.0 to 3.5 cm. The initial processing is made of solid wood. The seat of the cross chair is divided into:
● a. Cold-pressed seat plate: The seat plate completely covers the seat ring, and the multi-layer board is fixed on the seat ring with nails, glue, and pressed with a cold press for more than 12 hours to fully shape and fix it.
● b. Built-in type: The seat surface is inlaid at the inner ring of the seat, and there is decoration between the seat and the seat surface. Craft sewing. At present, the proportion of the seat plate style in our order exceeds 60%.
● c. Hollow: This seat is hollow and suitable for rattan seats or other soft surface cushions. The advantage is that the cushions can be interchanged.
8. Bending brace and material
To strengthen the structure of the wooden cross chair, we use four bending braces for each chair. Generally, there are two kinds of bending brace materials. One is cut from multi-layer boards formed at one time, and the other is soft and tough. Moringa is made by heating and cooking, shaping, and drying of abrasive tools. These two materials can be selected and used according to customer requirements.
9. Drilling and assembly
We have a full-time experienced technical worker responsible for punching and assembly. Before and after assembly, we must perform a screening comparison of the front and rear legs. The screening comparison mainly focuses on the angle and material. The pair with the same angle is selected for the assembly. The chair, whether it is the elevation angle of the chair or the distance between the legs, is more standard and more comfortable to sit.
10. Level the four legs.
In the leveling process, we use two processes: machine and manual. These processes help to level the four legs of the chair to ensure that the chair is more stable and safe after landing.
11. White embryo chair repair polishing
After the assembly, the white stubble chair will go to a special repair and sanding area for the first manual sanding and process repair. For cracks of small flaws, we still use wood flour and glue to repair, so the repaired wood is perfect as before and stronger. The overall chair must be polishedcarefully.
12. Primer bottom painting wipe color or spray paint
At present, the wooden cross chairs are spray painted and half stained. The spray paint will cover the wooden texture, and the color is mostly on the wooden texture. You can see the texture of the original wood. To maintain the natural color, we usually rub the color twice and then spray varnish again.
13. Secondary polishing
Like other wedding chairs such as wooden Chiavari chairs, after the first spray painting, experienced sanders will polish the chairs.
14. Second primer
In this step, we will carry out the second primer spraying or rubbing. This is the same as the first primer, and the thickness of the paint is the same as the first one. After the second primer is waiting to dry, we will sand it again making sure that the surface painting is easy to attach and clean.
15. Topcoat spraying and drying
Next, we will have the surface paint of the paint twice. After the surface paint is completely dry, we can prepare for the next step. Generally speaking, winter paint will dry very slowly. However, sometimes our automatic drying equipment and the indoor heating device may affect this, as the paint drying speed in winter is still much slower than usual. All experienced customers generally arrange their orders early before winter comes.
16. Install non-slip pad slider after passing the inspection
After the finished chairs are finished, our quality inspection staff will check them one by one and find that they are slightly defective. We will repair and arrange them, and then our workers will install non-slip mats.
17. Single chair packing
Next, we will pack individual chairs into suitable cartons until the container arrives and is shipped. Our cross chairs are exported to dozens of countries.
