Chemical Etching Products Non passed hole buckle plate can process:trench board,rough kneading board(friction sheet),pot hole board,decorative pattern spot,machine kneading board,metal label,bulletin sign etc. Photo chemistry etching can process nimbly,the usage range is broad.,produce straight hole,cone-shape hole,stair hole etc different hole. Entire piece etching sieving plate is made of a piece of flat plate,long usage life,compared with the weaved mesh,it is durable dozens times The superiority of the chemistry etching processing is that produce on the thin plate pore,below 1.0,below 0.5,above 0.1,is familiar and easy,successful.In recent years,the production practice also doesn't lacd the thick plate(0.5_2.0),big hole (above 1.0)customers,their pursues is this kind of up-scale product effect
