Tainuo Wood Industry Co., Ltd. Was a leader manufacture for best quality plywood. Our 25, 000 square meter production facilities are located within 126 kilometers of Shanghai, and the international air and sea transportation facilities it has to offer. As consumer trends towards environmentally friendly products grow, our export markets are also expanding. Currently, our main overseas clients are in Japan, the USA and Eastern Europe.
At the moment, we have various series of plywood. We have an annual production volume totaling 250, 000 cubic meters of plywood, in addition to hundreds of metric tons of molding and decorations. We ensure that all of our products are of uniform high quality standards. All plywood is processed to be perfectly straight using accurate machines and strict inspection procedures have been put in place. Moreover, realizing our responsibility towards both customers and the environment, we have removed all toxic chemicals from our manufacturing processes. All our lacquers are water-based, and free from harmful ingredients.
For more information about any of our products, please either visit our website or contact us directly. We are looking forward to having the opportunity of being able to cooperate with you in the near future.
Bonding WBP Glue line
Bonding meeting the test requirements of this British Standard and using an adhesive of the type which by systematic tests and by records in service of the product over many years has been proved highly resistant to weather, micro-organisms, cold and boiling water, steam and dry heat.
Species of Timber
If so specified by the purchaser, Gaboon or Okoume (Aucoumea klaineana), which is classed as non-durable, may be used provided that the name of the timber is included in the mark on the boards produced.
Quality of Veneers
Veneers may be rotary cut or sliced. The method of cutting is at the option of the manufacturer unless it is specified by the purchaser at the time of ordering. Veneers shall be smoothly cut.
These shall present a solid surface, free from open defects. They shall be free from knots, other than sound pin knots, of which there shall be no more than 6 in any area 30cm square (1ft2), and not more than an average of 2 per 30cm square (1ft2) over the whole area of the board. The veneers shall be reasonably free from irregular grain, due note being taken to the characteristics of the species being used. Isolated pinholes not along the plane of the veneers, and occasional closed splits are permissible. Veneers showing compression failure shall be excluded. Occasional minor discoloration is permissible.
There shall be not more than one edge joint in any 30cm (1ft2) width of the board, and the veneers shall, when jointed, be matched for color. There shall be no end joints.
The requirements for core veneers shall be the same as those for face veneers, with the following exceptions. Small splits are permitted, and there is no limitation on the number of pin knots or edge joints. Discoloration is permissible, provided this is free from dote. Veneers need not be matched for color. There shall be no end joints.
Limits of Manufacturing Defects in Plywood
Defective Bonding Not Permitted
Pleats and overlaps Not Permitted
Gaps In faces. Not permitted. Occasional gaps that occur during manufacture may be repaired by means of well-fitted veneer inserts bonded with a complying adhesive. In Cores. In any edge of a board, not more than one gap, which shall be not wider than 0.5mm. Obviously the presence of defects in cores can only be judged by the appearance of the edges.
At the time of leaving the factory, finished boards shall have moisture content from 6 to 14%.
Boards will be sanded on both sides equally
Length & Width.
The length or width of a board produced as a standard size shall not be less than the specified size nor more than 6.3mm (0.25") greater than the specified size
The lengths of the diagonals of a board shall not differ by more than 0.25% of the length of the diagonal.
Tolerances vary as follows.
4mm +.02/-0.6 6mm +.04/-0.65 9mm +.06/-0.75 12mm +.09/-0.82
15mm +.1/-0.9 18mm +.12/-0.98 22mm +.16/-1.08 25mm +1.8/-1.16
From the above we can assume that 6mm material will arrive at thickness' between 6.04mm and 5.35mm.
Face Veneer thickness:
For any three-ply construction, which applies to 3 and 4mm material, each face veneer shall be not thinner than 1/8" of the total thickness of veneers assembled dry.
Since the dry thicknesses of the boards are 3.6 and 4.6 respectively, we can assume that for these thicknesses only the face veneers will be as follows 3.6mm dry x 12.5% (1/8) = 0.45mm 4.6mm dry x 12.5% (1/8) = 0.575mm
This applies to boards thicker than 4.8mm (3/16")
Each face veneer shall be a minimum of 1.3mm and not thicker than 3.8mm. Each core veneer shall be no thicker than 4.8mm
