Second, look at the punching holes. Nowadays, panel furniture is assembled by three-in-one connectors, which requires punching a lot of positioning holes in the panel. The matching and accuracy of hole position will affect the structural firmness of cabinet box. Professional manufacturers use multi-row drills to complete a number of holes on the edge and surface of a board at one time. These holes are a positioning benchmark and the dimensional accuracy is guaranteed. Manual small factories use row drills, even pistol drills to punch holes, and the size error is large.
third, look at the cutting board. Cutting board is also called cutting board, which is the first working procedure in cabinet production. Large-scale specialized enterprises use electronic sawing machine to input the processing size through computer, and the computer controls the accuracy of material selection size, and can process several plates at a time. The performance of the equipment is stable, and the plate size accuracy is very high, the tolerance unit is in microns, and there is no stubble collapse at the edge of the plate. However, the small manual cutting saw used in small workshops has a large size error and often collapses.
fourth, look at the door panel. The door panel is the face of the cabinet, as important as the human face. Door panels produced in small factories are prone to moisture deformation due to improper treatment of substrate and surface technology.
5. Look at the assembly effect of the whole set of cabinets. Any size error in the production process will be displayed on the door panel. The door panel produced by a professional factory is horizontal and vertical, and the gap between doors is even. However, the door panel produced by a small factory will have uneven cracks and uneven gaps, some large and some small.
6. Look at the slide rail of the drawer, although it is a small detail, but it is an important part that affects the quality of the cabinet. Due to the size error between the hole position and the plate, there is an error in the installation size of the slide rail, which leads to the situation that the drawer is not pulled smoothly or loose left and right. Pay attention to whether the gap of the drawer is even.
