hot stamping minor faults

hot stamping process is an important part of binding processing, hot stamping processing is a more complex and technical work, its more than a dozen hot stamping objects, different performance, hot stamping materials and a wide range of, to make each variety, each batch of work hot stamping effect is very ideal is very difficult. Therefore, in addition to selecting materials as required, attention should also be paid to the correct processing during processing to ensure the quality of hot stamping. Based on the analysis of some hot stamping problems, the phenomenon of these problems is summarized, and the solutions are put forward.

1, hot stamping or hot stamping is not firm:

a. Light pressure or low temperature.-Increase pressure or increase temperature and time

B. hot stamping material does not conform to the hot object-choose the appropriate hot stamping material

2. No gloss after hot stamping, unclear paste plate: hot stamping temperature is too high, pressure is too high-reduce temperature, reduce pressure

3. The pressure after hot stamping of the same plate is different: the size of the picture and text area is very different and the pressure is uneven-increase the pressure of a large area of the picture and text, and the paper pad method can be used to correct it to adjust the size and area with equal pressure.

4. If the scalding fails or the scalding marks fall off:

a. hot stamping material does not conform to the hot object-choose the appropriate hot stamping material

B. Poor quality of hot stamping material adhesive layer-temporarily change to check its quality

c. The temperature is too low and the pressure is too low-readjust the temperature and pressure

d. no adhesive or excessive powder spraying during printing-use adhesive aids to remove the same material and normal

5. Good and bad in hot stamping:

a. Unstable material quality-a. Check material quality, temporarily change and make records

B. Abnormal temperature or pressure-check temperature, time and pressure, and adjust hot stamping

6. The text and text of the thin line are not clear:

a. Oversized embossing-large embossing pattern fabrics are not suitable for hot stamping fine line patterns

B. Light pressure-increase pressure and temperature to compensate

7. Leakage after hot stamping:

a. The pattern of the stamped object is too deep-increase the pressure

B. Low pressure and low temperature-increase the temperature by 5 ℃

8. The edges and corners of the handwriting are not obvious after hot stamping: the edges and corners of the hot plate or the body of the hot plate are not prominent.

a. Check whether the hot version is a note before putting on the hot version. If it is unqualified, repair it.

B. Place the edges and corners of the handwriting on the lower plate in a concave shape.

9. There is no convex mark after the hot plate is scalded: the upper plate of the bottom plate is not suitable for the convex or convex pad-the protruding surface of the same concave plate is padded at the hot spot of the bottom plate, and the production should be smooth and proper.

10. Hot stamping color sheet or metal foil is not bonded or bonded firmly:

a. No adhesive aid-fabric covers should be added with adhesive aid powder, smooth and non-porous or less porous covers should be added with adhesive aid.

B. inappropriate temperature or pressure-moderate printing temperature
