Zhong Ying hardware has learned that it is helpful for the enterprise to design the signs for the business of the use of the signboard. The common metal sign making process is oxidation, corrosion, stamping, high light, printing and so on. The manufacturing technology of plastic signs includes electroplating, baking paint, drawing, stamping and so on. Below we pay attention to the main points of the process of making the sign.
First, what kinds of oxidation processes are there? Fast oxidation, electrolytic coloring, immersion and tread dyeing, low temperature sealing, second times oxidation, electrophoretic paint substitution, different oxidation power sources, etc.
Two: what kinds of techniques are there in common metal signs and pads:
The 1. is that the thick metal panel is squeezed out of a convex word with a die and a punch press.
The 2. is to use a thin metal panel with a convex die and a punch to pull out a convex word.
The 3. is etchant on stainless steel, aluminum or copper plate etched out of a convex word.
Three, the printing process of the signboard:
1. screen printing: silk screen, sign, character, scale, figure, location hole and color should conform to the requirement of drawing. There should be no scratches or stains on the appearance of the products. The adhesion of the ink film should fit the needs.
2. machine printing: it is metal color printing, the use of plate offset press, colorful, to achieve the effect of excessive gradual change, making the graphic lifelike, vivid and vivid.
Four, the process of the cutting nameplate:
1. bottom disposal, stamping forming, high light cutting (deep drawing)
2. stamping forming, bottom disposal, high light cutting (Leng Ji)
3. etched convex word, bottom disposal, high light cutting (etch) high light sign
Five, there are several kinds of electroplating processes:
Electroplating generally consists of gold plating, silver plating, bronze plating, antique copper, nickel plating, nickel plating and double color gold.
Attention should be paid to electroplating.
The coating thickness, it directly affects the thin wire drawing, easy abrasion coating drawing, not up to the effect of plastic processing time to avoid bubble coating.
Six, the cautions of the lacquer:
Lacquer room and environment should be clean, avoid dust, paint dilution should be uniform, baking time control.
Seven, brand stamping equipment and technology:
The machine used for stamping of convex plastic signs has a flat press, a scald machine, a hot press and a ramp stamping machine. The press machine has two kinds of workable and mechanical choice. A hot press is suitable for many gold stamping signs. The ramp - climbing gold - stamping machine is suitable for stamping with arc - shaped plastic convex sign. Hot stamping temperature has a plan to reach the hot stamping foil and plastic contact appearance strong adhesive, hot stamping film without stripping it. Hot stamping is the induction function of heat and pressure. The temperature, pressure and time should cooperate well. If the plastic part is not deformed, the word can not be thicker, the line should not collapse, and the time should be as short as possible. The temperature, pressure and time control should be determined after the test. With the mastery of the question of the technical knowledge of the making of the signboard, a more exquisite product will be made for the logo design of your enterprise.
