steel checker plate metal rods for sale metal plates for sale

Metal plate production process there is a necessary step, and that is color. Color might use a tool that is metal colored machine, it can be said that metal plate electrophoresis machines, electronic color machines, electronic coloring machines.??This device is the sign industry in recent years, it emerged from the working principle to supplies and coloring methods are new signs color equipment, signage color technology is one of the most significant innovations ever, with its excellent quality, excellent performance and make People amazing speed, appeared to praise signage industry attention and users.??Metal signs, the industry has done is generally known, metal signs generally are required to have the bump effect, this aspect is to make the sign of a certain three-dimensional and layered, but the main thing is to avoid frequently wipe so fuzzy graphic content even fade.??Signs etching process has three main aspects, namely: graphic form, graphic etching, graphic color. The signs coloring methods are mainly hand-filled paint (commonly known as the point paint, painting), painting, color electrophoresis. The above-mentioned electrophoresis machine is used electrophoresis color.

 

Sign making processSignage plate determines the quality of signs, and sign making process, determines the quality of the production of signs. In the production process, in strict accordance with the relevant standards need three processes to execute, we can guarantee

Certificate good quality signage products.1, the bottom plate production. Signs, text, graphics and typesetting plate they use a photographic plate, the first system out of a single piece of the original, and then even the sun drying machine even imposition. Imposition respectively when taken according to the requirements of precision parts

Imposition and with no spacing spaced imposition. Signs size less demanding, can be no imposition pitch. After printing, cut or cut directly after stamping. Signs that require high dimensional accuracy, should

Using spaced make-up, after the printing is completed by the positioning hole punch press molding position, the distance between each of the parts may be 2mm, 2mm hole for positioning aperture spacing 4mm, the whole area may be

400 × 400mm, or according to the process set design. If color printing signs two-color or two or more colors, photographic negatives rules should be positioning line, positioning holes can be painted on a photographic plate negatives main pattern

In order to ensure the accuracy of the positioning of the punching.2, silk screen positioning. Positioning is the key to accuracy, positioning accuracy is the key to determine the quality of the metal printing plate. Custom screen printing plate on the plate, is to ensure that the graphics are printed on the same workpiece

The exact position of the surface, uniform color overlay accuracy and meet the requirements of process means. According to substrate materials, different, screen printing plate positioning method also all have different body, commonly used are the following

:The first is sidelined positioning. It applies to straight edge artifacts, such as: nameplates, panels, all kinds of disk, etc., at the time of printing the article can be positioned close to the two right-angle side of the workpiece.The second is chrome positioning. Suitable for printing shaped molding of the workpiece, the workpiece can be molding blanking the frame, after trimming the gap, according to step aside positioning method, the frame needs to adhere to the position on the platform
