Buyers Must See - Quality Identification Of Octagonal Sheet Hot Stamping

< p > < a href= "http://www.91se91.com/" > octagonal > /a >, that is, aluminum ironing, the surface of it needs various kinds of colors.

There is a glue on the inside.

Its shape is octagonal, solid called octagonal.

< /p >

< p > in recent years, the international market has more and more environmental requirements for garment < a href= "http://www.91se91.com/" > Accessories > /a >.

Dazzling diamonds, which contain heavy metal lead, are thought to cause skin diseases, especially children's skin allergies, causing repeated difficulties in clearing customs.

Octagonal tablets are widely used as hot stamping materials because they do not contain heavy metal lead.

< /p >

< p > however, some domestic manufacturers of cheap and inferior octagonal tablets do not dare to flatter. They only win at a price of more than ten yuan and twenty yuan, but the quality has become a fatal killer that can not make them develop! < /p >

General requirements for < p > octagonal tablets: < /p >

< p > 1, color octagonal film can not be rubbed or washed and decolorization; < /p >

< p > two, must be firmly attached to the clothes, can withstand hand rubbing, wash test, and can not be easily broken off.

< /p >

< p > three. Under suitable parameters, it can be completely heated without overflow.

< /p >

< p > requirements for quality octagonal tablets: < /p >

< p > 1, the color must be very good, can give a very good gloss, the color does not sink.

It can produce different luster under different light.

To achieve this, a good plating process is required.

The color of octagonal sheet is actually electroplated, so the technology of color matching is very important in electroplating.

Inferior octagonal color is very poor in terms of technology, color and color, and the color is single.

And the plating effect is very poor, easy to appear in the simple rubbing, rubbing, water washing decolorization phenomenon, and even lead to serious pollution clothing problem.

< /p >

The stamping surface of < p > two and octagonal sheet is fine and smooth.

Whether or not it can punch out fine edges and corners of octagonal sheet is not only related to whether the production mold is excellent, but also involves the key problem of making the aluminum material of octagonal sheet itself excellent.

Irregularities are fatal problems, such as being biased in one direction and high in the bottom.

Because of the poor quality of the aluminum material itself, there are several problems after being stamped by the machine: 1. the combination of the top and the surrounding points, faults and even cracks; 2. after stamping, the top and the surrounding joints form a small circle; 3. eight edges and corners can see the obvious part of the burst, giving a very obvious feeling -- rough! < /p >

< p > three, requiring uniform gluing, not too much or too little.

Inferior quality < a href= "http://www.91se91.com/" > octagonal slice < /a >, some manufacturers in order to solve the problem of ironing up, in the octagonal piece inside the coating a lot of glue, the octagonal piece of the bottom is full.

A lot of glue has been out of the horizontal line of the bowl of the octagonal sheet before it is hot.

From the work principle of < a href= "http://www.91se91.com/" > hot glue < /a >, we know that the hot melt adhesive is melted and expanded after being exposed to high temperature and penetrated into the clothing and cloth to achieve the purpose of firm adhesion.

So there are several reasons for overflowing glue: 1. there are quality problems in the glue itself; in the 2. bowl, there are too many glue, and the hot sol is heated and expanded. After seep into the clothes, there are still a lot of glue that can not permeate, and only overflow to other parts. 3., the permeability of the clothing itself is very poor; 4., the octagonal film is irregular, the glue is heated, and the irregular side is spilled.

5. the temperature is too high and the time is too short.

It is different to press the octagonal sheet and press the drill.

Octagonal sheet is aluminum material with high heat pfer speed.

If the temperature is too high, the glue will expand quickly and cause bubbles in the center. The glue will have to burst from the crack between the octagonal sheet and the clothes.

< /p >

< p > four, there must be no stamping deformation, high quality octagonal sheet, even in the whole package, it is difficult to pick up the bad stamping deformation material, the whole is very uniform.
