Nine basic steps of automotive prototype surface treatment

as a prototype model often used in industrial product design, insiders know that it has two most important functions. The first is structural verification, the second is the exhibition. It is very important to make the surface treatment of the prototype model displayed in the exhibition. The key is the process. Now I introduce several kinds of models and hope to share them with you. First, water transfer is to use the pressure and activator of water to dissolve and transfer the stripping layer on the water transfer carrier film. The basic process is: 1) Printing of film: printing various patterns on polymer film; 2) Spray primer: many materials must be coated with a layer of attachment, such as metal, ceramics, etc. To transfer different patterns, different base colors must be used, for example, the wood grain basically uses brown, brown, Earth yellow, etc. The stone grain basically uses white, etc; 3) Extension of the film: let the film be flat on the surface of the water, and wait for the film to stretch and level; 4)Activation: with a special solvent (Activator)Activate the pattern of the transfer film into an ink state; Five) Transfer Printing: use water pressure to print the activated pattern on the printed material; Six) Washing: Wash the impurities remaining in the printed workpiece with water; Seven) Drying: the printed workpiece will be dried, and the temperature depends on the prime and melting point of the material; Eight) Spray top coat: spray transparent protective paint to protect the surface of the printed object; Nine)Drying: dry the surface of the object sprayed with topcoat.
