Foaming and coating: two processes of door panel materials in the market

In the door panel material market, we can often see door panels of various styles, patterns and patterns. Most of these dazzling effects are achieved by plastic absorption or coating process. So, what is the difference between blister and coating? Next, the comparison is made from four aspects: thickness, coverage, molding method and edge sealing.

thickness

The thickness of the blister film is usually thicker than that of the coating film.

covering surface

The coverage of blister film is 5, while that of packaging film is 6.

Molding mode

The whole substrate is molded in the plastic absorption process and bonded after softening at high temperature; The coating process is a cold process through the superposition of grooves.

Edge seal

The blister process usually has no edge sealing, while the coating process has edge sealing.

Advantages of coating process

The coating process, as an upgraded version of the coating process, is relatively more complicated. Not only is it technically superior, but it can also better protect the substrate and prevent the plate from deformation and cracking. At the same time, due to the six-sided design, the door panel has stronger bearing capacity, more durability and more environmental protection. In addition, the groove connection mode also increases the possibility of mixing the design and color materials of the door panel, providing users with more diversified choices.

Door panel quality evaluation

When evaluating the quality of these two door panels, we should pay attention to the following points: first, we should look at whether the overall color is uniform and the surface is flat; Secondly, it is necessary to investigate the high temperature resistance, waterproof and moisture-proof, and scratch resistance of the door panel; Finally, the bearing capacity and deformation resistance of the door panel substrate should be considered. Generally speaking, the coating process has more advantages in the quality control of door panels.
