MDF molded door: MDF is double-sided molded, the door core is hollow, the style is single, and the grade is low. Blockboard double-package door: semi-manual semi-mechanical production, door core pine frame, fine wood door panel and two breads, single style, flat door, low grade. All solid wood 榫 structure door: simple mechanized production, all solid wood, with pine, iron ash, eucalyptus, ash and other materials, its structure is mainly for door frame 榫 connection, inlaid door core board, in the market is a high-end products. Due to the reason of solid wood, there are fatal defects in the quality: the door body is easy to deform, the joint at the joint is cracked, and the door core plate shrinks and white. Solid wood composite door: It is produced by mechanized assembly line and uses solid wood composite technology. The door is made of pine wood, and various valuable solid wood concealed inner edge seals are covered with various precious wood veneers. The moulding wood thread adopts various precious woods, and the door core board adopts perforated particle board and medium density fiberboard. It is stable for a long time, no deformation and cracking. The appearance is as natural and elegant as the whole solid wood. The materials and styles can be more choices. It is a medium and high-grade product. Flat solid wood composite door: the door leaf frame is generally fir or pine finger joint material (small amount of other wood is used), the middle part is made of laminated timber, or the paper honeycomb with molded door is used, hot pressing 5 centimeter MDF, surface hot pressing package Covering 0.3-0.6mm solid wood veneer, because it needs to be hot pressed twice, the surface of the door leaf is very flat, and the inside is fully bonded, there is no possibility of cracking. There are no pure wooden solid flat doors on the market, because if the entire door is made of wood, it will not only cause the door leaf to deform (the filling material will play a balancing role, reducing the possibility of deformation). Moreover, the weight of the door leaf is very heavy, and the ordinary hinge cannot be tolerated. Modeling solid wood composite door: Most of the market is a plate-type structure. Because the veneer curve coating technology of the closing line is only in a few famous brand factories, many of the market use solid wood lines to close the mouth, which eventually leads to the color difference of the door leaf. , thus affecting the overall effect. Most of the door panels of the modeling door are MDF, which reduces the possibility of cracking due to the shrinkage of the door core plate, but the oil mixing door is still easy to crack.
