How to control the edge quality when using edge banding machine

Edge edge quality is influenced by many internal and external factors. Including equipment condition, raw material condition, and operation skilled.Edge banding machine manufacturer(hicas)suggest that 6 condition should be more attentioned at anytime.

1.when you use thickness edgeband for banding, nip roll should in the best position. Because all most problem is owing to pressure too tight. Edgeband is longer compare for workpiece so When the feed roller presses the edge with a longer section to the edge with a perpendicular to the feed direction of the force, at this time the glue is not completely cured, the bonding strength is not high the tail and releasable adhesive is not strong.

2.The indoor temperature can not be too low when machining, in general, should be more than 15 DEG C, especially with a thick edge, flexibility will be insufficient, to ensure the normal operation of the preheating device, without preheating device can be used when the hair dryer heating method makes edgeband softening, this method is especially suitable to the curve edge. It’s not the processing workshop.

The edge banding influence edgeband quality.Good quality with edge sealed products at tight edge. The edge of poor quality of the products with a seal edge gap is large, there is a clear line. Trimming machine when backing easily in the surface scrape marks. Thick edge from the cross section, the glue should be slightly concave on both sides of the central than at the edge, edge products with a letter is tight, the effect is good.

3.Water wood edge material rate is not too high, should be stored in a cool and dry room, material requirements without dust, the optimum water content in 8-10%.

4.The edge is fast, adhesive under low pressure have good dispersion and on the permeability of the matrix, to have a good initial viscosity and pressure in a short period of time should be instantly glued bond. When used to ensure hot melt temperature in the normal temperature range, long time high temperature will make the glue; low temperature hot melt adhesive to reach good fluidity, when used to grasp the supplier data.

5.Hot melt adhesive coating should be glued to make parts outside slightly extruding whichever is too large, there is a black line at the edge, the influence is beautiful; too small, not enough. In order to test the bonding strength of adhesive film is continuous, can use transparent hard PVC test can also be brought; ordinary edge band edge, while the glue is not cooling the edge tear test.

6.The front edge machine using milling cutter device manufacturers, semi-finished products to the edge cutting quality can affect the sealing effect. In order to prevent the explosion of products manufacturers generally used when cutting edge notch (commonly known as small saw blade), the best effect after cutting should be able to see a small section of saw marks but feels like not too deep. The small blade marks edge sealing edge at the prison, can see a black line can even see the gap, too shallow and explosive.
