What makes the quality of PVC edge banding different? Shanghai edge banding manufacturer Angmi Xiaobian will answer for you.
1. The base material of PVC edge banding
In the production process of edge banding, the base material is the carrier of edge banding and the foundation of edge banding. We call it PVC edge banding if it is made of PVC powder, and we call it ABS edge banding if it is made of ABS base material, etc. The base material is the property, so it is very important to have a good base material. High-quality edge banding starts with the selection of base material. Angmi edge banding uses PVC powder imported from Germany for granulation. At the beginning of granulation, the problem of the same color of the edge surface in the later stage is considered, and the color is adjusted together with the edge surface printing, which solves the problem of the uniformity of the bottom surface of the cut edge.
2. The curvature of the avatar of PVC edge banding
When the edge banding is bonded and extruded, the good edge banding should have a certain inward bend in its width direction, while the bad edge banding is flat, and even worse, it will be reversed, so it is not easy to bond.
3. PVC printing
There are two processes for printing the surface of PVC with patterns, one is printing and the other is thermal transfer film. Thermal transfer film products are relatively smooth, but due to the high cost, slow transfer speed, and the color cannot be well matched with the board, it has been replaced by printing. Some inferior PVC edge banding strips have too high calcium carbonate content, and if the printing process is used, there will be a problem of discoloration. Angmi has adopted more advanced water-based ink printing technology since 2016, making the printing effect of Angmi edge banding strips far beyond the reach of domestic edge banding strip manufacturers.
4. PVC edge banding strip back glue
The quality of the back glue will directly affect the bonding effect. The back glue is actually not glue, but a bridging agent that plays a bridge role in the middle. Especially in cold weather, due to the low temperature in the workshops of some furniture factories, the efficiency of hot melt glue and back glue is greatly reduced, and these furniture factories often attribute the responsibility to the quality of the edge banding strips, which is unreasonable.
