Production of metal characters mainly three points need to be resolved:
1: production of metal panels and floor;
2: production of three-dimensional wai;
4: polishing plating.
Following a brief introduction to each step of the solution and the use of tools.
(1) the production of panels and floor, metal cutting is currently the most used plasma cutting machine as well as flame cutting, but it is understood that the flame cutting is mainly for thick material, and processing products need to do more and more refined processing, more practical for thick metal mold processing.
Plasma cutting machine is divided into wet and dry cutting and wet cutting, the main principle is produce high-temperature plasma cutting metal, usually a dazzling spark and a not very good smell gas, cutting speed is fast, generally by plasma cutting of metal will a little slag scraping, because of high temperature gas cannot be taken away the residue of the melting. Currently on the market to sell the main plasma 1.3x1.6, 1.3x2.5, 1.3x3 m, the size of the 1.3x2.5, the use of more than. In the choice of plasma cutting machine is mainly to see whether there are 2 or 1 cutting of the cutting speed and accuracy, the accuracy is not very high, the need to do manual processing 3 power, there are domestic power and import power, power and according to the flow, the thickness of the metal plate has a certain limit.
(2) making metal words surrounding edge, now doing Wai edge equipment manufacturers is relatively small, making Wai side main is bending and the arc, metal words surrounding edge especially stainless steel round edge is too hard, not good bending or bent to straight and easy deformation forms an arc, which is most difficult in the word of stainless steel production. Stainless steel word to do straight edge angle is beautiful. CNC slotting machine it is in stainless steel or iron grooved, slotting position choose where to bending, I look especially magnesium Dachser slotting machine has a computer in the operations there, as long as the input font can be automatically opened groove, and hand cranked how many degrees, the effect very good, really reached a straight edge at right angles to the effect. Again is to use manual open, draw the line, then ruler gestures, knife knife slot, this approach more trouble is also time-consuming.
(3) welding, metal connection, if do not have the kind of cut tooth edges only take welding now welding is nothing more than a spot welding and soldering, welding made slightly more beautiful, but also useful for soldering, soldering need polishing galvanization processing, around the edge of the look will be bright. Do you go to the spot in a clean manner. But it is still a bit of trouble to master these welding techniques.
(4) polishing plating, now a lot of advertising production plants have a polishing machine, mainly to do metal polishing treatment. After the end of the polishing treatment, if the customer requires that a very bright effect, but also need to do electroplating.
