Collect of metallic finishing craft

Finishing is equal to the method that adopts physics or chemistry to form the surface layer that one has some to plant or a variety of characteristic pledge in material surface. Can promote to a high office through finishing the function of the many respects such as product exterior, simple sense, function.



The exterior: Line of \ of color, design, Logo, burnish (3D, 2D)
Simple sense: Feel, thick clumsy is spent, life (character) , clipper-built etc;
Function: Sclerotic, fight dactylogram, resist cut;

.
Finishing technology of the metal is contained first below




.
One, zincous oxidation
Positive pole oxidizes: Basically be aluminous zincous oxidation, it is to use electrochemistry principle, the surface in aluminium and aluminium alloy is inherent an Al2O3 (alumina) film. This oxidation film is had defend the special character such as gender, adornment sex, insulating properties, wearability.

.
2, electrophoresis
Electrophoresis: Use at stainless steel, aluminium alloy to wait, can make the product presents all sorts of color, maintain metallic burnish, enhance exterior function at the same time, have better anticorrosive function.
Technological process: Drying of → of pre-treatment → electrophoresis

.
3, small arc oxidizes (MAO)
Small arc oxidizes: In electrolyte solution (it is alkalescent solution commonly) bring to bear on inherent pottery and porcelain changes tall voltage the process of exterior film layer, this process is the result of physical discharge and electrochemistry oxidation synergism.
Technological process: Pre-treatment → hot water washs drying of → of → MAO

.
4, PVD vacuum plating
Deposit of physical gas phase (Physical Vapor Deposition, PVD) : It is a kind of industry makes the technology that go up, it is to basically use physical process to come the technology of deposit film.
Technological process:
→ is cleaned to enter furnace vacuumize before PVD → washs target and ion to clean end of plated film of → of → plated film, refrigeration gives furnace → aftertreatment (polishing, AFP)

.
5, eletroplate (Electroplating)
Eletroplate: It is to use electroanalysis action makes metallic surface adheres to the craft of film of a metal rises to prevent to erode thereby, ascensive wearability, conductivity, glance the gender is reached promotional and beautiful a kind of technology that waits for action.
Technological process: Pre-treatment → does not have chromium of plating of → of stannum of cyanogen copper-nickel alloy without → of cyanogen alkaline copper

.
6, pulverous spray
Pulverous spray: It is to use dusting device (machine of electrostatic gush model) go to coating spray the surface of workpiece, below electrostatic action, the adsorption with pulverous average meeting at workpiece surface, form farinaceous coating; High temperature of farinaceous coating by is roast shed smooth solidify, turn the effect into each different (the different and phyletic effect of coating) final coating
Technological process: Go up a → is electrostatic remove dust low temperature of → spray → sheds smooth → roast

.
7, the metal pulls silk
Pull silk: It is to pass abrade product to form strain line in workpiece surface, rise to decorate the method of a kind of finishing of the effect. What the basis pulls the grain after silk is different can divide for: Straight grain pulls silk, random grain to pull silk, moire, grain coming back.

.
8, gush is arenaceous
Gush arenaceous: ? Does aether of dispatch take along sth to sb consider abb of pregnant of  of Γ of  of  of sprain palm  to sift Lai of white of Kong of fine Dong of Si of  of  of Guan of Dong Kong white to call  of ぜ of compose of  of Gui of rice huller of  of ぜ of jading  Hua rice huller is adept able to bear or endure is adept of Jue rice huller able to bear or endure Xi of  of ⑸ of Wei of Wu of Jue Dun Nao?

.
9, polishing
Polishing: Use flexible the retouch treatment that polishing tool and abrasive grain or other polish medium have to workpiece surface.
In the light of different polishing process: ? ) of process of polish of foundation of stand erect? , cast in (finish machining process) cast with essence of life (glazing process) , choose right rag wheel to be able to achieve optimal polish result, polishing efficiency progresses in the meantime.
Technological process:




.
10, etch
Etch: Indicate normally etch also say actinic etch, point to after passing exposure plate making, develop, will etch the diaphragm purify of area, chemical solution is contacted when etch, achieve deliquescent erodent action, form concave and convex or the effect that hollow out shapes.
Technological process:



Exposure law: The project leaves according to the graph piece get the materials ready dimension - data is preliminary - material is cleaned - stoving → sticks film or drying of → of develop of → of exposure of → of drying of Tu Bu → - etch → takes off velar → OK
The net imprints law: Open makings → to clean plate (stuff of metal of stainless steel other) → silk screen imprints → etchs → takes off velar → OK
