When the drawing is completed or a new product is designed, that is, before it is put into the market, the first thing you want to know is the market benefit of the product; Or want to know whether the design drawing and the physical object are different or reasonable, at this time, it is recommended that you first do the hand plate model.
So, in general, the hand plate is a functional model for checking the appearance or structure rationality by making one or more models according to the product design drawing or structural drawing without opening the mold. So today, the model family model to talk about the hand board several common craft!
1、 Grinding: before spraying, friction is used to rub the sprayed object or coating surface with friction medium such as sandpaper, pumice and fine stone powder, which is called grinding. It is an important step in the spraying process, usually manual operation, and can also be carried out by pneumatic or electric instruments. Grinding throughout the whole spraying process, not only the blank, the bottom or putty need to be polished, but also after the finishing coat. The function is to remove burr, floating rust, oil pollution and dust on the surface of the bottom material; Remove the coarse particles and impurities on the coating surface to obtain a flat surface; The smooth coating surface should be polished to a certain roughness to enhance the adhesion of the coating. It is divided into dry sanding and wet sanding, which is lubricated with water or other wetting agents to obtain smoother surfaces and wash off the grinding powder.
2、 Polishing: there is mirror polishing and transparent polishing, which must be based on polishing! The mirror polishing is divided into mechanical mirror polishing and chemical solution mirror polishing.
Mechanical mirror polishing is a smooth and bright surface by polishing (rough grinding, fine grinding) and polishing process on metal materials.
The mirror polishing of chemical solution is to soak the chemical solution to remove the surface oxide skin to achieve the bright effect.
Transparent polishing refers to the polishing effect of PMMA or PC material after polishing, and polishing with polishing wax to the transparent effect.
3、 Spray: the coating method applied to the surface of the coated material by spraying gun and dispersing into uniform and micro droplets by pressure. It can be divided into air spraying, airless spraying, electrostatic spraying and various derived methods of the above basic spraying forms, such as high flow and low pressure spray, thermal spraying, automatic spraying, multi group spraying, etc. Because the hand board model is mostly hand-made oil-spray painting, it is generally necessary to have a master with 15 years of painting experience like huanghailong, a family of model generations, in order to grasp the skills of painting and color matching accurately! Spray is also the most intuitive experience of the appearance of the hand board, and is also the most extensive technology at present!
4、 Screen printing: screen printing belongs to the hole printing, which is called four printing methods together with flat printing, embossing and gravure printing. The printing of the hole plate includes transcribing, engraving, spraying and screen printing. The principle of hole printing is: when printing plate (the hole can be made on the basis of paper film plate or other version) during printing, ink can be transferred to the substrate (paper, ceramics, etc.) through the hole of the hole plate through certain pressure to form image or text.
5、 Electroplating: the process of plating a thin layer of other metal or alloy on some metal surfaces by electrolysis principle is a process of applying electrolysis to attach a layer of metal film to the surface of metal or other materials to prevent metal oxidation (such as corrosion), improve wear resistance, conductivity, reflective property, corrosion resistance (copper sulfate, etc.) and improve aesthetics.
6、 Anodizing: electrochemical oxidation of metals or alloys. The process of forming an oxide film on aluminum products (anodes) due to the action of applied current under the corresponding electrolyte and special process conditions. Anodizing, if not specified, usually refers to sulfuric acid anodizing. In order to overcome the defects in surface hardness and wear resistance of aluminum alloy, expand the application scope and extend the service life, surface treatment technology has become an indispensable part of aluminum alloy. Anodizing technology is the most widely used and successful technology at present.
7、 Water transfer: water transfer printing technology is a kind of printing that uses water pressure to hydrolyze polymer on transfer paper / plastic film with color pattern. With the improvement of people's requirements for product packaging and decoration, the use of water transfer printing is more and more extensive. The principle of indirect printing and perfect printing effect solve many problems of surface decoration of products, mainly used in the transfer of various ceramics, glass paper, etc.
8、 Laser etching: also called laser engraving or laser marking, it is a process of surface treatment by optical principle. The effect of laser beam of high intensity focused laser emitted by laser is to expose deep layer material through evaporation of surface material, or to cause trace of chemical and physical changes of surface material through light energy, or burn off some materials through light energy, or burn off some materials through light energy, To show the etched graphics, words.
9、 Drawing: surface drawing is a surface treatment method which forms lines on the surface of workpiece by grinding products, and plays a decorative effect. Because surface drawing can reflect the texture of metal materials.
10、 Integrated molding: metal inserts, rubber (soft rubber metal or plastic materials), etc.
