Button quality: high quality octagonal piece of high demand

​

The octagonal film belongs to the aluminum ironing product. When it is used in the production of octagonal tablets, it can not be faded. It can not be easily removed from the clothes, and it can not be spilled out. These are the basic requirements for the production of octagonal tablets. The following four points are the four high requirements for high-quality octagonal tablets:

First, the color must be very good, can produce a good gloss, color will not die. In different light, can show different luster. To do this, a good plating process is required. The color of the octagonal film is actually plated out, so it is very important to grasp the technique of color matching in the process of electroplating. Inferior octagonal tablet color in the grasp of technology is very poor, the color of sichen, feeling a single color. And the plating effect is poor, easy to rub, rubbing and washing in there bleaching is simple, even lead to serious pollution problems of clothing.

Two. The pressing surface of the octagonal film needs fine smoothness. Whether or not a piece of octagon with a fine edge can be punched is not only involved in the production of the die, but also relates to the key problem of whether the aluminum material of the octagonal film itself is good or not. Inferior domestic rhinestud, irregular is a fatal problem, such as bias in one direction, with high. Because of its use of aluminum material itself quality is not good, some problems occurred after stamping machine is: 1. at the top and around the point of integration, fault, or even rupture; 2. after stamping, the top and around the point of integration, formed a small circle; 3. eight corners, can see the obviously protruding part, give a person very clear feeling rough!

Three, the requirements of glue evenly, not too much or too little. In order to solve the problem of "no ironing", some manufacturers have applied a large amount of glue to the inner sides of the octagonal sheets to fill the bottom of the octagonal film. A lot of glue has not been hot before, it has been higher than the octagonal bowl groove horizontal line. From the working principle of hot glue we know, hot hot glue is under high temperature after melting expansion, penetrate into the fabric inside to firmly. So there are several general glue overflow: 1. adhesive quality problems; 2. bowl slot too much gum, hot sol thermal expansion, there is still some gum penetration in the infiltration of clothing, can spill into other parts; the permeability of 3. clothing itself is very poor; 4. rhinestud irregular. The glue is heated, side overflow never rule. 5. temperature is too high, time is too short. Hot press octagon and ironing drill are different. Octagonal sheet is aluminum material with fast heat transfer speed. If the temperature is too high, the gum is rapidly inflated, resulting in a bubble in the middle, glue will have to break from the octagonal and clothing cracks.

Four, there must be no stamping deformation, high-quality octagonal tablets, and even difficult to pick the whole package of bad stamping deformation of the material, the whole is very uniform.
