In general, the aluminum prototype is making CNC machining. Let Molto introduce the process of aluminum prototype: designing drawings, programming, CNC machining, polishing, assembly, fuel injection, laser engraving, electroplating and other processes.
Designing drawings: prototype drawings are generally done with AutoCAD. Need to have professional designers to do. In general, the format of prototype drawings is mainly. igs/. stp/. stl/. prt/. X-t and so on.
Programming: programmers analyze 3D data and write programming languages that control CNC machining centers.
CNC Machining: executing the program command, more exactly it should be the case--tungsten steel knife in accordance with the procedures set the path, in the upper and back of the carving, the extra part will be removed, thus getting the prototype of the aluminum prototype model.
Polishing: the parts after processing in CNC machine tools, its surface will have a lot of burrs and knife marks. Usually polished with polished cream or sanded. You should pay attention to the problem when sanding, first, you need to use coarse sandpaper for rough grinding. Remove the coarse burrs from the surface and then polish the fine lines.
Assembly: installing the various parts together, after processing, then do data detection.
Fuel injection: in the aluminum prototype surface sprayed with a layer of paint, so that it reaches the same color as the design drawings, generally speaking, we use PPG coating to spray oil, bright color, lasting, not easy to fall off.
Laser carving: using the laser to destroy the surface’ paint, so that part of the location is light. For example: mobile phone keys, car DVD keys, lenses and so on.
Electroplating process: electroplating refers to the salt solution containing the gold-plated genus, with the substrate metal as the cathode, through the electrolysis effect, so that the plating solution of the cations in the metal surface deposition, forming a coating surface processing method.
