Pakistan costumer order 50pcs zinc etching plates

IN MAY, HOT SALES, 50 zinc etching plates packed for delivering to customer in Pakistan.

Etching refers to removing the protection of the area to be etched after exposure to plate making and development, and contacting chemical solution during etching to achieve the effect of dissolution and corrosion, forming the effect of concave-convex or hollow molding. The earliest can be used to manufacture copper plate, zinc plate and other printing embossing plates. Etching machines can be divided into chemical etching machines and electrolytic etching machines.

Its basic principle is that under vacuum and low pressure, the radio frequency generated by the ICP radio frequency power supply is output to the annular coupling coil, and a certain proportion of mixed etching gas is coupled to the glow discharge to generate high-density plasma. Then, these plasmas bombard the surface of the substrate, the chemical bonds of the semiconductor material in the pattern area of the substrate are broken, and volatile substances are generated with the etching gas, which are separated from the substrate in the form of gas and are drawn away from the vacuum pipeline. In the mutual comparison of etching and stamping process characteristics, the advantages of etching are that the sample production cost is low, almost all metals are within the etching range, there is no limit on metal hardness, no scratches, no burrs, and the design is fast, simple and efficient. , The process takes 48 hours, the influence of material thickness on the tolerance is ±10%, and the product packaging and transfer are extremely convenient. The manufacturing cost of stamping is high, although all metals can be processed, but the hardness is too large, too small, easily broken metals are not available, there are scratches on the cutting edge, there are local burrs, and if the process is changed during the design process It is very time-consuming, the cost is high, the process takes at least a few weeks, and the packaging and transfer of the product is difficult.
