Hollow door refers to the wood frame, plywood, fiberboard and derived thin sheet material for a variety of panel doors. Here follow the argument is hollow doors difference in terms of solid wood doors, etc., after the hollow doors are not successful is hollow in the middle of the hollow doors are generally the same as the model has a range of fillers, but the same is generally not completely solid Bale . Important characteristics of the hollow door: hollow doors important with light, manufacturing convenience, low cost level features. Compared with solid wood doors and composite wooden doors, because the receiving hollow planning to make big loss since the huge hollow doors, and the doors are very beneficial to prevent the use of the process gave birth to the onset of sagging. Built to withstand groups planning optimization and improvement also has a certain meaning. On the other hand, because the hollow doors frugal planning, manufacturing facilities, production costs are relatively low, in the use of large-scale implementation of proper and widespread. Molded door carved molding method that is receiving pad produced on plywood board pushed out with the same outcome engraved picture of the door to the kind of molded door receive some more pictures of European painting, and the results came out first glance engraved with the outcome very close to, but higher than the outcome to be beautifully engraved smooth naughty. Consider this aspect of the program is the mold when they ask to play sex, the other is to prevent molding process gave birth to the onset of damage to the substrate surface. Of course, the pressure molded door model has a picture of this, but since the foundation of the original picture is recessed into the plane of the substrate, the door of the quilt is also fundamentally flat. Thus in the process of manufacture and transportation is very convenient. However, since this molded door is produced under high temperature and pressure conditions (hot temperature of about 250 ℃), repressed picture also more attractive, and thus a higher demand for substrate. Especially when the substrate is more stringent quality requirements when plywood, there should be blocked from the core and the core stack and other shortcomings, but also good quality glue. The kinds of molded door panels also receive a decorative veneer board, carved door ask how to play better outcomes, but also more stringent production process.
