Manufacturing Process Of Solid Wood Composite Door

- Aug 03, 2018 -

The door leaf adopts the frame of fir integrated timber. It needs to be thickened and sanded and pressed 3 l"nn.1 thick MDF. After thick sanding, the hot pressing is covered with thin wood and the substrate is uneven in the original process, resulting in stickers. The corrugated board surface is corrugated. The door core board adopts the peripheral end face milling type to make the door leaf more three-dimensional. The pressure line is used to fix the door core board, so that the door core board has the replaceable thickness, and the original process core core is improved. When there is a problem with the board, the problem of replacing the entire door leaf is required.


The manufacturing process of the door cover adopts the balance structure of double-sided pressing of the MDF board to enhance the bending resistance, avoid the deformation of the door cover, the door closing is not tight, and the gaps around the door are not the same. The veneer finish ensures consistent texture of the door leaf and door cover.


The door sleeve is made by vertical gluing of two MDF plates, which comprehensively utilizes the high longitudinal and transverse bending strength of the MDF. The wooden door cover after the improvement process is combined with solid wood and wood-based panels, the cost is reduced, the product quality is improved, the product structure is rational, and the surface is beautiful. This process has been tested and has been matured in production, achieving mass production and being recognized by the market.

Veneer: Since the inner material of solid wood composite door adopts ordinary wood and MDF, the use of solid wood veneer is the most important process of solid wood composite door, which has a decisive effect on its final quality and use effect.


Wood and MDF glued wood and medium density MDF are bonded with adhesive. In order to ensure the quality of the glue, it is necessary to ensure the processing precision of the mating surface. In addition, it is necessary to select rubber grades with high bonding strength, such as urea-formaldehyde resin glue and poly Vinyl acetate emulsion, etc.


raw material


It is a medium-density fiberboard that greatly reduces the amount of wood used and is very environmentally friendly and low-carbon.


Core

The solid wood composite door is generally a five-layer hot-pressed composite structure. Most of the manufacturers' door core materials use fir laminated timber, and the higher-grade solid wood composite door adopts pine integrated pine.


Veneer


Since the inner material of the solid wood composite door adopts ordinary wood and medium-density board, the thin wood veneer is the most important process of the solid wood composite door, which has a decisive effect on its final quality and use effect.


Great production flexibility

1. Unloading a component to process a component finish to process an assembly. The process is characterized by first machining the components and surface treatment and then assembling them into a door. Since the finishing material is very thin and does not have the conditioning conditions, the processing precision of the components is required to be high.


2, a component is processed, one assembly is assembled, and one finish is processed to handle the corner. The process feature is that after the overall processing of the composite door is completed, the finishing process is performed, and the door blank can be trimmed before the veneering.


3. Make a door blank, a milling shape, and a finish. The panel of the solid wood composite door adopts a 18 mm thick MDF, and the milling cutter produces various concave and convex effects similar to the solid wood door, so that the shape is flexible and the selectivity is strong. By improving the above conventional process, the author proposes a more practical solid wood composite door processing technology.
