Plastic pad hot stamping how to deal with?
The hollow part shall be resisted from the inner side of the product, and the pressure on the hot stamping surface shall be kept uniform(1) the stamping temperature is too high. Should be properly lowered.(2) the heating body of rubber board, mould and rubber roller is too close to the stamping foil. The distance between heating body and hot stamping foil should be appropriately increased.(3) the stamping time is too long. Should be appropriate to shorten the surface of hot stamping, loss of light, dark(1) the stamping temperature is on the high side. Should be properly lowered.(2) stamping time is too long. Should be properly shortened.(3) the distance between hot stamping foil and heating body is too small. Should be appropriate to increase the stamping layer wrinklesDoor, rubber, printing, touching, rubber roller and stamping foil too close. Appropriate distance should be drawn.(2) the temperature of rubber sheet, mould and rubber roller is too high. Should be properly lowered.(3) the parts of the window, such as the window, not the tire clamp, the uneven stamping pressure. Products should be hollow place pad, so that the stamping pressure to maintain uniform.(4) the hot stamping foil is not smooth. Foil delivery device shall be checked.(5) the surface tension of hot stamping foil is too small. Should be increased tension, tighten the foil, partial leakage of foil, leakage and surface spots
(1) the foil binder does not match the material of the base material. Variety of foil should be replaced.(2) the surface of the product has mould release agent, grinding agent, dust, fingerprint and oil stain. Should use alcohol and other solvents to wipe the surface of the product.(3) the stamping temperature is too low. Should be appropriately improved.(4) the stamping pressure is too small. Should be appropriately improved.(5) the stamping time is too short. Should be appropriately extended.(6) the foil is out of date and the adhesive is invalid. New foil shall be replaced and overdue foil shall not be used.(7) the surface of the hot stamping face has reinforcing ribs or other highly different structures, resulting in uneven stamping pressure.
