The Manufacturing Process of Panel Furniture: Detailed Explanation of Panel Furniture Processing Techniques

The Production Process of Panel Furniture:

Cutting

Cutting is the process of cutting the panels used in furniture production. Due to the relatively simple structure of panel furniture and the high precision required for connectors, the cutting process can directly cut the boards to the desired dimensions using high-precision cutting saws.

Edge Banding

Edge banding involves applying strip-shaped edge materials such as wood strips, veneer strips, single veneer strips, thin wood strips, melamine decorative board strips, plastic film PVC strips, ABS engineering plastics, pre-painted decorative paper strips, etc., to the edges of the panel by applying adhesive and pressing, to enclose the edges of the panel. The base materials can be particle board, medium-density fiberboard (MDF), plywood, or laminated panels.

Groove Processing:

1.Drilling

People need to drill various types of holes on the components of panel furniture for connecting parts and dowel holes. There are mainly four types:

① Connector holes: used for installing and connecting various types of connectors.

② Dowel holes: used to install dowel rods for component positioning.

③ Hinge holes: used for installing various types of door hinges.

④ Guide holes: used for positioning various types of screws and facilitating the insertion of self-tapping screws.

2.Slotting

Slotting is a process that can create grooves, dadoes, and line holes on various workpieces. People generally use the grooves on panel furniture for installing panels, such as the back panel of cabinets, the bottom panel of drawers, etc. Workers can also use them for installing various hardware accessories, such as tracks for sliding doors, cables, decorative strips, etc. Slotting is mainly done using a router. And people also process some narrower grooves using a saw machine.

Packaging

People often package panel furniture in a flat-pack format. During transportation, workers disassemble the furniture into various panel pieces, stacked together, and packaged into smaller volumes. Upon arrival at the customer’s location, they assemble it on-site. This method not only maximizes transportation space efficiency but also reduces transportation costs. This type of furniture packaging is flat-packaging.

Requirements for the Process of Panel Furniture:

一Mechanical Processing Stage Process Requirements

1.Pressing Paper Process Requirements:

After processing, the paper must be firmly and smoothly adhered to the finished board. It should not have any issues such as delamination, bubbles, scratches, creases, torn paper, pressure marks, or other impurities.

2.Quality Requirements for the Pressing Machine:

a. The board should have strong adhesion with no delamination. When inserting the components, they must align with the adjacent sides of the frame. The positional deviation between the upper and lower boards after cold pressing should be less than 1.5 cm.

b. The surface of the components after cold pressing should be clean and smooth, without obvious frame marks, bending deformation, scratches, or excess adhesive.

c. Curved core strips should be tight, with a smooth surface and a natural transition, without any glue contamination.

3.Quality Requirements for the Milling Machine:

a. The molds must be accurate, with the processed shape and dimensions matching the drawings. The non-joint curve position allows a tolerance of ±1.5 mm.

b. The processed surface must be smooth, with smooth lines and a natural transition. The surface of the components after processing should be flat, without any edge collapse, tearing, or scratches. The surface of the components should be clean, without any impurities or sawdust.

Quality Requirements for the Painting Process

Sanding of Raw Boards:

The surface of panel furniture components should be free from burrs, with smooth edges and no unevenness. The corners of the boards should be chamfered to avoid sharp edges. After sanding, there should be no signs of improper sanding.

Putty Application:

The surface should be solid, smooth, and evenly coated with putty. It should not have sand breakthroughs, pits, sandholes, air bubbles, or excessive buildup of putty. Workers must clean the putty in the holes properly.

Primer Application:

Strictly follow the paint formulation and ensure a clean surface. The coating should be free from pinholes, graininess, paint residues, uneven spraying, shrinkage holes, edge swelling, or blistering. The primer must cover the putty layer.

Dry Sanding:

The painted surface should be smooth after sanding, without pinholes or nail marks. The sanding marks should be straight and fine, without any grooves. If there are sand breakthroughs at the edges, joints, or curved lines of the paint coating, a primer should be applied before sanding again.

Sticker Component Requirements:

After sanding, the components should be smooth, glossy, with no sand marks or breakthroughs, and no scratches. After sanding, people should wipe them clean before placing them back on the iron rack.

White Base Requirements:

For glossy and matte components, sanding should be done using 400#, 600#, and 800# sandpaper. The sanded components should be smooth, glossy, without sand marks or breakthroughs, and no raised fibers. However, they should be translucent. There should be no signs of improper sanding, and oil pens should not be used to cover sand breakthroughs.

Dust Blowing Treatment:

The painted surface should be clean, free from dust or particles. People must clean wood chips in holes or slots thoroughly.

Topcoat Application:

The surface should be evenly sprayed, smooth, and flat, without runs, shrinkage holes, edge swelling, blistering, or wrinkling. The surface should be similar in gloss to the flat plane. No accumulation of paint or scratches are allowed in non-sprayed areas, and the paint edges should be neat.

Clear Coat Spray Application:

The surface should be evenly sprayed, smooth, and flat, without runs, shrinkage holes, or edge swelling. People should keep non-sprayed areas clean, and the paint edges should be neat.

Polishing Requirements:

After polishing, the surface of the boards should have a mirror-like gloss, without visible polishing lines. There should be no dust, wrinkling, or blistering.

Quality Requirements for Packaging Process:

Manual Edge Trimming and Staining Quality:

a. After edge trimming, the components must be free from injuries, sand scratches, or scratches. And workers should keep the board surface clean, without any wood chips, glue, or other debris.

b. The edges of the manually trimmed parts must be smooth, and worker the right-angle sections should be sanded to maintain their sharpness. They should not be sanded into a rounded shape.

c. The trimmed parts should undergo color treatment to match the tone of the board surface.

Manual Installation Quality:

Component installation must be secure, and workers should keep the board surface clean. There should be no scratches, pressure marks, dents, or surface abrasions.

Packaging Quality Requirements:

a. Products must pass inspection before packaging, and people must arrange the components according to the stacking requirements specified in the packaging list.

b. People must attach the sealing tape firmly, and tightly secure the packaging straps. The stacking of products must meet the specified requirements.
