First, examine the edge banding of the boards. High-quality cabinets have delicate, smooth, and pleasant-to-the-touch edge banding with straight, smooth lines and precise joints. Professional factories use straight-line edge banding machines to complete edge banding, cutting, trimming, chamfering, and polishing in one go, ensuring the most accurate dimensions. Small workshops, on the other hand, use brushes to apply glue, manually press the edge banding, trim with a utility knife, and polish with a manual polishing machine. Due to uneven pressure, many areas are not secure, and this can cause formaldehyde and other harmful substances to evaporate into the air.
Second, check the drilling. Panel furniture is assembled using three-in-one connectors; the fit and precision of the holes affect the structural stability of the cabinet.
Third, check the board cutting. Board cutting is the first step in cabinet production. Large, professional companies use electronic panel saws with computer-controlled material selection based on computer-input dimensions. They can process multiple boards at once, and the equipment is stable, producing boards with extremely high dimensional accuracy, with tolerances in the micrometer range.
Fourth, examine the door panels. The door panels are the face of the cabinet, as important as a person's face. Door panels produced by small factories are prone to warping due to improper base material and surface treatment.
Fifth, examine the overall assembly of the cabinet set. Any dimensional errors in the production process will be reflected in the door panels. Cabinets assembled by small factories will have uneven door seams, gaps that vary in size.
Sixth, check the drawer slides. Although a small detail, it is a crucial factor affecting the quality of the cabinet. Errors in hole positions and dimensions can cause misalignment in the slide installation, resulting in drawers that are difficult to pull out or loose from side to side. Also, check if the gaps between drawers are even.
