Solid process door knowledge and production process
According to the introduction of woodworking experts, the solid craft door refers to the solid wooden door with decorative veneer on the surface, which means that the whole door is made of a variety of wood.
The solid wood door can be called a real solid wood door, which is derived from the same tree species and has no skin attached to the surface. However, pure solid wood doors are easily deformed if they are not very good at work.
The solid structure of the solid wood craft door leaf is in the form of solid wood. It is made of solid wood substrate such as solid wood panel, laminated timber, blockboard and so on. It is made of sill, head (traverse) and door core board blank, and will be decorated with veneer in solid wood line (symmetric groove line type). Then, according to the modeling requirements, various thresholds, heads, billet blanks, solid wood lines, etc. are framed into door leaf slabs, and the gaps between the heads and the thresholds are often closed (also closed) Right angle 榫 joint, also used air gun nail (claw nail) joint, the core of the door core board, the solid wood line and the head (traverse), the door sill is glued; finally, the surface of the slab is used for sawing Sheets, plywood, thin MDF, veneer and high-quality veneer, artificial veneer and other cladding and veneer. The thickness of the door core board is usually thicker than the threshold, the head, etc. In order to reduce the cost of materials and prevent cracking, the door core board can also be made of medium and high density fiberboard, multi-layer plywood, particle board and the like.
In many factories, there are also solid doors. There are some factories that don't have this one thing. Why is there no such thing, because this mechanism is a composite layer in the middle, which can reduce the amount of deformation. If there is a bar in the middle, the upper and lower composites will reduce the door deformation. Many factories do not pay attention, many people do not know the key points of this technology. This is the structure of this door.
Production process of wood structure door with panel structure:
First make the door frame well, and the door core board is ready. The production process technology of the panel structure solid wood craft door is similar to the solid structure solid wood craft door. The difference is that the wooden strips or slats such as fir are firstly spliced ​​to form various threshold materials and heads (crosspieces) which meet the structural requirements. Then, the two sides are covered with plywood, thin MDF and other slats, and then the planing and decorating thin wood (wood veneer) or sawing thin plate is glued, and the ends of the head are opened, the two sides are milled and the long groove is processed. The inside of the sill is blinded, milled and processed. If the door core board adopts thin solid wood panel or laminated material, it can directly cut the circumference and surface of the door core into a line shape; if medium and high density fiberboard is used, it can be firstly milled and then used with a thin veneer for vacuum coating to form a special decoration. surface. Finally, the prepared various thresholds, heads (crosspieces), door core plates and other combinations are assembled into door leaves.
In the production process of solid wood craft doors, there are many technical factors that affect its quality. Among the existing standards, there are some regulations, such as processing accuracy, material type and technical requirements. In this standard, there is no requirement for veneer appearance requirements, paint film appearance requirements, physical and chemical properties of paint film and mechanical environmental performance. The mechanical strength and sound insulation of the door are not mentioned in the standard. In the standard improvement, we have to do it. In particular, our company must have such data available to consumers.
