first generation processing technology

board: the board of the first generation cabinet technology is mainly composed of large core board and density board, and white fireproof board is pasted on one side (using all-purpose glue or white emulsion). With the advent of the era of environmental protection, the large core board gradually withdrew from the big stage of the cabinet and was replaced by more environmentally friendly moisture-proof board and particleboard (Note: the unqualified moisture-proof board added more adhesives than the large core board). Due to the humid weather in the south, the density board will expand and mildew in less than a year (coastal areas), so it automatically withdrew from the scope of cabinet board

edge banding: manually brush the cross-section of the board and the edge banding strip with all-purpose adhesive (the thickness of the edge banding strip is generally between 0.3-0.45mm) and dry it for a period of time, close the edge banding strip and the board, press it manually, and then manually trim the edge with sharp tools such as blades. Generally, only the visible front is sealed, and the back, bottom and seam are not sealed. This edge banding method is still used in a large number of cabinet factories, including "brand cabinets"

assembly: the first generation of cabinet assembly process can be called the era of "straight through screws". Because the cabinet industry is just emerging, a large number of businesses are eager to get off the production line, so they refuse professional equipment (row drilling) that requires capital and technology. So far, this technology still occupies the mainstream position in the cabinet processing industry. The so-called "straight through screw" as the name suggests is to use the electric hand drill to directly pass the self tapping galvanized screw through the plate body for cabinet splicing and assembly. It is simple, practical, low-cost and does not need the row drill technology. The cabinet must be assembled in the factory. At the same time, in order to save plates, general cabinets are often made into conjoined cabinets (two or more cabinet spaces share one or more side plates). The backboard is directly nailed at the back with gun nails or iron nails. The simplest way to identify this process is to see (without professional knowledge). Whether the cabinets can be seen during delivery. If the manufacturer moves cabinets one by one, it means that the first generation cabinet assembly process is adopted. If there is only a package of boards with positioning holes, it means that it is the second or third generation cabinet assembly process

hanging Code: the hanging code of the first generation process generally adopts triangle hanging code. When you open the hanging cabinet, you can see the white iron sheet in the corner, which is generally painted

backplane: the backplane generally adopts 3mm single-sided Polaroid board or density board, which is directly nailed at the back with gun nails or iron nails

second generation processing technology

board: 16mm particleboard was used. At that time, major brands, including imported brand cabinets, all used this kind of board as the board body. However, the waterproof ability of particleboard was poor, and many cabinets did not do relevant waterproof protection at that time, which made the sink cabinet collapse in advance. Replaced by the third generation of plates - moisture-proof board

edge banding: use hot melt glue machine for edge banding and manual trimming

assembly: the second generation cabinet assembly process is called the "row drill" era. The assembly of modern cabinets is connected with quick assembly parts. The holes are processed with row drill in the factory, inspected and packaged, and then assembled with three in one (eccentric key) on the installation site. It is assembled into a unit cabinet, so when the medium and high-end cabinets are delivered, you can't see the cabinets, but only packages

hanging Code: it mainly adopts round hole "L" shaped hanging code, which is good-looking but not well stressed

backplane: 3mm single-sided Polaroid board or density board, slot type installation

third generation processing technology

plate: use 18 environmental protection moisture-proof plate

edge banding: automatic gluing, edge banding, edge trimming, head breaking, polishing in place at one time, and edge banding with anti-collision strips

assembly: on the basis of the second generation cabinet assembly process, add wood Falcon reinforcement

hanging Code: use hanging code or hidden code

backplane: use double-sided melamine density board, slot type installation

waterproof: aluminum foil waterproof of sink cabinet (a silver aluminum plate)

table top processing: the table top processing must go through cutting, bonding, milling, grinding and polishing Among them, the bonding process is more critical. If you are a little careless, you will expose an ugly glue line, and then polish it, which determines the smoothness of the table - whether it is bright or not is the trick. Then there is polishing. The decisive role is polishing wax. A good wax can make the table brighter and Cleaner - of course, you have to use a special mechanical polishing machine to rub and apply the automotive high gloss wax by hand. Strictly speaking, it should be a perfunctory behavior

there must be a water retaining line process for the water retaining of the countertop, and there should be a backing strip under the countertop
