PRODUCT DETAILS

Product Introduction

Product Name:

Anodic oxidation

Introduction to anodic oxidation:

Anodic oxidation is a kind of material protection technology for metal materials to form oxide film on the surface by anodic current applied externally in electrolyte solution

product usage:


Metal materials or products after the surface anodized treatment, its corrosion resistance, hardness, wear resistance, insulation, heat resistance and so on have been greatly improved so the anodic oxidation technology in the construction industry, aerospace industry, electrical and electronic industry, food industry, chemical industry and pharmaceutical industry, transportation and other fields has been widely used

technological process:


 Oil removal→alkali wash→acid wash→polishing→anodic oxidation→water→ coloring→ sealing→drying

Our Advantage

1、Till 2019, we have been engaged in the field of etching for 20 years. In 2015, the company invested in building a new industrial park in nantong, learned from the successful experience of shenzhen and kunshan branch, and started to involve in the field of metal anodic oxidation, committed to the technical innovation, development, production and sales of anodic oxidation products in the middle and high-end market.  

2、The company has passed ISO9001:2008 quality management certification and ISO14001:2004 environmental management system, passed ISO / TS 16949 certification and high-tech enterprise certification in the automobile industry in 2016, and obtained a number of patent certificates. Zhuolida has always attached great importance to technology research and development. It has set up laboratories and engaged and trained high-tech talents, striving to be a benchmark enterprise in the industry.

3、The company is a member of PCMI, an organization of the world etching association, which can share information and equipment of the global etching industry.

4、Introducing multiple anodic oxidation production line, with liquid automatically add system and regeneration system, at the same time also pay attention to environmental problems for the development of the company, self-built large sewage treatment system, wastewater powerusageeffectiveness back to more than 40%, is specialized in metal etching industry one of the few construction without water treatment system of the corporation to become green environmental protection enterprise.

5、Many metals need anodic oxidation after etching, which can help parts and other products to improve the accuracy and the beauty of finish products, etc. Nantong zhuolida integrates etching and anodic oxidation processes into one, which can well meet the processing needs of customers and truly provide product processing services for customers.

6、Shenzhen ZhuoLiDa kunshan ZhuoLiDa and nantong ZhuoLiDa three production bases, the comprehensive area of 40000 square meters of nantong industrial park have been completed, involving etching plating electrophoresis anodized laser welding and vacuum diffusion welding, and other fields, can provide integrated solutions for customers' products including nantong ZhuoLiDa workshop on the first floor of a building for electrophoresis; The second and third floors are etching workshops, with more than 20 conventional import and customized non-standard precision etching lines, which can meet the requirements of production capacity and precision of various products. The fourth floor is the second floor of the vacuum diffusion welding workshop.


PRODUCT CHARACTERISTICS

  • 01

          Advantages and USES of anodic oxidation: 

    (1)the protective improve wear-resisting corrosion resistant climate corrosion resistance of the parts made color brightness

    (2)decorative film, color film 

    (3)as insulation as a capacitor dielectric film, aluminium wire coil insulation film, each micron thickness, which can improve the resistance to 25 v voltage

    (4)and the adhesion strength of the organic coating, coating 

    (5)improve the bottom and inorganic coating binding force, as the bottom layer of plating enamel 

           (6)the development of other functional USES, sedimentary magnetic alloys for memory in porous membrane element solar panels ultra hard membrane dry lubricating film catalytic membrane and so on

    What is the relationship between anodic oxidation time and film quality?

    Under the conditions of the same solution concentration and other technological conditions, with the extension of anodic oxidation time, the oxide film generated on the surface of the workpiece (within a certain range) will gradually thicken, and the pores will increase, which is favorable for dyeing


  • 03

              Is stirring of solution necessary for anodic oxidation?

Anodic oxidation of compressed air mixing solution is very necessary, because the heat generated in anodic oxidation of accumulated on the surface oxide film in the solution, can lead to oxidation film dissolve faster, so that the comprehensive performance of fabrication by using compressed air mixing solution, make the parts of the heat generated by the disperse quickly, and can make the solution after cooling to cool the surface, make the solution over the surface of the parts cycle so as to ensure normal oxidation process, but also beneficial to improve the uniformity of the thickness of oxide film

  • 04


    Implement more metal materials is aluminium anodized aluminum anodic oxidation generally in acidic electrolyte, with aluminum as anode in the electrolysis process, oxygen anion and aluminum produced oxide film formed at the beginning of the film is not close, although have certain resistance, but the negative oxygen ion in the electrolyte can still reach the surface of the aluminum continue to form oxide film with film thickness increases, the resistance is bigger, thus the electrolytic current smaller
