Sieve tube is a kind of perforated mesh commonly used in the field of silencer, oil filter, filter element, anti-sand filter rolled into a cylindrical shape, the material of sieve tube is mainly iron plate, aluminum plate, stainless steel plate and other different materials of metal plate, after punching to cut, roll, welding, rounding process is completed, can be completed according to customer demand polishing surface treatment.

The processing process of the screen tube to stamping punching to complete the primary molding, and then through the cutting of the way to roll, through the implementation of the roll of welding, rounding, if you need to polish, that is, surface treatment, and finally complete the molding. Zhuolida etching process is not so, but first through the etching process to complete the flattening of the screen molding, and then through the roll-to-roll etching automatic exposure machine to roll round and welding, collectively known as roll-to-roll etching, for stainless steel coil material, copper coil material and other flexible into the roll material, to achieve the whole volume of permission to automate continuous etching, the production of products more stable; this seamless welding of the roll round approach, also known as roll-to-roll seamless welding. High-precision roll-to-roll etching process can make the product without black spots and welded joints without burn marks, so that the product surface is smooth and relatively high flatness. It is widely used in coffee filters, car filters, etc.
