Forging the exterior aggrandizement of the mould and modified engineering technology, can undertake impression surface and matrix whole is designed as a system, use technology of exterior aggrandizement modified and besmear film technology integratedly, make the surface obtains data itself is had hard and hopeful have specific property. Use modern technology change to forging the material surface of the mould, inferior the processing technology of the composition of exterior layer, structure and function calls exterior modified skill, basically include 10 kinds as follows: 1.

Electrochemistry is changed in electrolyte solution to counteract dispatches from foreign news agency to spread effect, spare parts surface forms the technology of oxidation film to call electrochemistry to change modified technology. On the project, often also change electrochemistry modified technology to call zincous oxidation or in relief polarization. Latter, the one great progress that electrochemistry changes a technology is small arc plasma positive pole oxidizes, it can raise exterior hardness significantly, or form new-style color to decorate velar layer, very good application is had in mould industry. 2.

The surface is formed change aggrandizement uses gush bolus, extruding, laser concussion, boil pressure, the technique such as efflux of supersonic concussion, oscillatory concussion, high pressure, make generation of material surface layer plays plasticity to be out of shape, introduce remains to press stress and the change that produce microstructure construction, will improve data with this fatigue resistance and fight cankerous ability, will promote the stability of the spare parts and wear. 3.

Exterior posture changes aggrandizement uses electron beam, laser bundle wait to undertake heating quickly to material surface, make the surface, inferior the surface forms new look to change area and exterior aggrandizement metallographic, the special property that obtains having fine structure and aggrandizement look thereby expresses facing. 4.

Ionic infuse uses the ion that vacuum system ionization gives, quicken below tall voltage, surface of direct infuse material, form very thin ionic infuse layer, change the composition of material surface and structure, improve material surface performance. 5.

Organic technology of as organic as inorganic coating technology coating, advocate if point to,use coating (makings of paint, lacquer, painty, rare makings) gift spare parts surface defends specially, adornment and flame retardant, show lukewarm wait for a function. Inorganic coating technology, be in the metal apparently form inorganic overburden or exterior film. Inorganic overburden or exterior film have specific chemical composition, structure and form appearance, can gift the property with matrix and coating new system or function. 6.

Exterior alloy is changed (diffuse ooze) be in metal or metalloid deposit base material apparently, through diffusing action infiltration arrives inside base material surface, change structure of the chemical composition of material surface, photograph, in order to raise the performance characteristics of material surface. 7.

Chemistry is changed in putting metallic spare parts certain chemical solution medium, make its surface forms passivity compound velar layer, in order to improve the performance of material surface. On the project, velar layer basically has commonly used passivity compound the hair of surface of chromate passivation film, phosphatic passivation film, oxalate passivation film, steely spare parts is blue etc. Additional, in project application, often exterior surface roughness reduce craft (burnish, polishing, roll light to wait) reach the surface is chromatic wait to also be attributed to chemistry to change technology of modified of this kind of surface. 8.

Electrochemistry of metal of technology of metallic electrochemistry deposit is deposit, it is to point to to with electrochemistry the method makes an exterior deposit in the metal or multilayer the technology of metallic film, alloy film or compound film, also call eletroplate technology. With eletroplate the method can make an exterior preparation give a function in the metal a variety of film of each different. 9.

Antirust technology metal sends unripe chemistry below environmental medium action or electrochemistry change calls corrosion of metals, common says to rust or rustily. Antirust metal is to prevent a metal to be in production treatment, carry, carry, store cankerous technology is sufferred in reaching use process. 10.

Technology of hot dip film heats up dip film technology to call hot plating again, be will be nodded at frit by dip of plating metal stuff the engineering technology that film forms in metal of inferior other liquid state or alloy. The characteristic of technology of hot dip film is an alloy layer is formed between base metal and film metal. CNC Milling CNC Machining
