2, oil spraying treatment, the requirements of paint with the kind of metal baking paint.
3, surface hot stamping treatment, (electrochemical aluminum transfer), but the shape of the surface requirements (also known as thermal transfer)
(1), about the hot stamping plate, that is, the pressure head portion of the material selection to the red copper material for the best, because the red copper heat dissipation, heat transfer is relatively good, in the metal belongs to the neutral material, neither too soft nor hard, not only easy to process, there is a certain degree of elasticity, durability, very good; but the actual use of the copper, the copper is a very good material. Very good; however, the actual use, many manufacturers to reduce material costs, the choice of more than aluminum alloy printing plate, so that the cost of production in the hot plate can save some, but because aluminum is too soft, poor service life, if the batch is very large, with a period of time but also have to re-make the plate, plate fee is not cheap, so it should be a comprehensive consideration of the issue of material selection.
(2), about the stamping process conditions are easier to understand, is the stamping pressure, stamping temperature and stamping time.
(3), the most important is the choice of raw materials for hot stamping, that is, hot stamping paper, choose to pay attention to different hot stamping substrates with matching only, not a hot stamping paper can eat all the materials, which is mainly related to the thermal transfer printing of the adhesion firmness of the problem.
4, water transfer printing principle is as follows: first print the pattern to
Transfer paper, the printing surface with a layer of protective film. Transfer paper production is complete. When printing, the protective film must be torn off, wet with water, and pasted on the printed surface. Due to the action of the water, the ink adheres to the surface of the product. Tear off the transfer paper again. Wait for the water to dry. The silver transfer is completed.
