Wood cutting is one of the most fundamental and critical processes in furniture manufacturing, directly determining the structural stability, appearance quality, and material utilization rate of the finished product. Through scientific cutting techniques and precise equipment operation, product quality can be effectively improved while raw material waste is minimized.

1、‌Base Frame Fixing‌: Assemble the chair legs and seat board first, secure with screws while ensuring levelness to prevent tilting.

2、‌Backrest and Armrest Fixing‌: Align mortise-tenon joints or screw holes; apply controlled force when tapping or tightening to avoid wood splitting.

3、‌Mortise-Tenon Joint Reinforcement‌: Apply high-viscosity wood glue (20,000-25,000 mPa·s) on load-bearing areas for stability, and low-viscosity glue on non-load-bearing areas to prevent oozing.

4、‌Stability Test‌: Check stability at each stage, promptly adjust loose components, and ensure overall structural integrity. 

1. Use 320-600 mesh sandpaper for step-by-step grinding to remove burrs and enhance the adhesion of the paint surface.

2. Clean the wood surface to remove any dust or oil residue.

3. ‌Environmental requirements: temperature 20-25℃, humidity below 65%, good ventilation but avoid strong wind direct blowing. 

4. Spray 2-3 thin coats of base coat, with an interval of 6-8 hours each, to ensure uniform coverage.

5. After drying, lightly sand with 400 mesh sandpaper to eliminate the graininess.

6. For changing from light to dark color, first spray a layer of sealing base coat, then mix the color pigment and spray evenly. The spraying thickness should be controlled at 30-50 microns.

7. Surface drying takes 1-4 hours, and dryness (able to be lightly touched) takes 24-48 hours.

8. Complete curing (resistant to wear and tear) takes more than 72 hours. During this period, avoid heavy pressure or friction.

1. The Soft cushion and leather finishing techniques are the core aspects of furniture manufacturing, directly influencing the comfort and aesthetics of the products.

2. The filling material is mainly high-density sponge. It needs to be cut according to the specifications and fitted onto the wooden frame. Some high-end products may also incorporate clothing cotton or down to enhance the softness.

3. The fixed materials need to be controlled for their tensile strength, as this value affects the durability and resilience of the furniture.

1. The materials need to be inspected piece by piece to avoid any defects.

2. Cut and sew the soft padding section to shape it.

3. During the sewing process, it is required that the stitch lines be straight and symmetrical. For example, the number of stitches per inch for the cushion cover should be 10 to 11.

4. Place the cut leather or fabric cover on the wooden frame and secure it with gun nails to ensure a tight fit without any wrinkles.

5. The corners need to be rounded off with a 45-degree slope transition. The gun nails should be smooth and concealed, without any protrusions or missed placements.

1. The appearance should be symmetrical and natural, with no color differences or cracks on the leather surface, and no stains or loose threads on the fabric surface.

2. The quality of the manual work is particularly crucial. Careful checks must be conducted on the flatness and tightness of the buckle components.
