A set of sofa, its basic production process can be divided into: the production of the sofa frame, base cutting sofa legs sit on colored sponge adhesive nails, suit sofa coat.

The quintessential piece of furniture is the sofa; after a tiring and busy day, when we come home, we usually like to rest on the comfort of our own sofa. It can be said that besides the bed, the sofa is the furniture we touch the most every day. So, how is the sofa made, do you know? It doesn’t matter if you don’t know, today I will take you to see the manufacturing process and process of a sofa.

A set of sofa, its basic production process can be divided into: the production of the sofa frame, base cutting sofa legs sit on colored sponge adhesive nails, suit sofa coat.

1. Fabrication of the sofa frame and base

Before the sofa starts to be made, it is necessary to have a master with rich experience to draw the board. Without a good model, it is impossible to make a good sofa. Because each connection requires careful calculation, the appearance that is almost made is not a small gap.

After the board is done, the frame of the sofa will be formally made. The current sofa frame is mainly divided into two kinds of materials: solid wood and composite board. The frame of the sofa, in my opinion, is similar to the human skeleton, supporting the whole sofa. The firmness of the sofa frame structure and the rationality of the design angle will affect the quality and function of the sofa.

Manufacturing process of solid wood frame

1. Dry wood

Because wood contains moisture, the moisture content of wood is controlled within 12% by drying, which can greatly reduce the deformation rate of wood. Resistant to deformation, rot and insects.

2. Cutting

Cut out the backrest, armrest and other parts according to the model drawing. After that, the wood is polished, wind sheared, trimmed and other processes.

3. Tenon reinforcement

The parts of the sofa frame are closely connected by the tenon joint method.

Mortise and tenon technology has been passed down in China for thousands of years. If you have a set of old furniture at home, it must be spliced using tenon and tenon technology. Otherwise, it won't be so strong. In addition, in order to strengthen the frame, each joint of the frame must be positioned with a precisely cut wooden tripod, and white glue must be applied after the joints are joined by gun nails or screws. (reinforcement)

Here you need to pay attention to some small details, and the stitching at the interface must be precise.

4. Primer

The main thing is to add springs and bandages to the sofa. Put an elastic band on the back frame of the sofa! Because the back frame is not as strong as the seat frame, it is enough to use the elastic band. There are also so-called black belts, which are made from discarded tires.

Springs generally use serpentine springs (also called S-shaped springs) to increase the bearing capacity of the sofa, and then use special spring clips to fix them to reduce noise. The spring installation must be firm, and there should be no abnormal movement when pressed hard. The quantity depends on the specific needs.

5. Masked cloth

The cushion area is covered with the air-permeable mesh fabric we know, which can effectively prevent moisture and breathe, and increase the life of the sofa.

2. Sofa filler

The stuffing inside the sofa includes sponge, down and rayon. The types of sponges are mainly high, medium and low sponges with different densities. The sponge in the sofa will affect the sitting feeling of the sofa. The quality of the filled sponge will also affect the service life of the sofa.

(1) Cut out different shapes of sponges according to the shape of the sofa.

(2) Wrap the sponge outside the sofa frame.

3. Coat cutting and sewing

Each side of the sofa you see is a board, which is called a leather board. Place the leather board on the cowhide to draw, and pay attention to avoid unqualified leather. Start shearing later.

It can also be scratched with a blade. Of course, if it is cloth, you can use electric scissors, which can cut multiple layers at a time.

After cutting the leather, pack the sofa cushions, armrests, backrests, and classifications so that the next "sewing" can be smoothly and efficiently produced.

Sewing, flat car, joining the cut leather one by one, the sewing process is very important, it is related to the appearance and craftsmanship of a sofa.

4. Press the top line

Single-needle car crimping, both single-thread and double-thread need to be pressed to a margin of 5 mm, the lines are symmetrical, straight and clear, and the direction is regular and even.

pressure line. Double-needle car crimping, put the fabrics on top of each other at the joint of the flat car, and the double-needle car will sew firmly. The same is true for the entire coat production process of the fabric sofa. But cutting cloth will be easier than cutting leather. But it's all the same for skilled workers.

5. Transfer to the door

Cover the sofa with the sewn leather or fabric cover. According to the appropriate positioning of the appearance of the sofa, fix it with gun nails. Fabric sofas need to be equipped with hardware such as zippers.
