               Dacromet process


"Dacromet" is the best technology to replace the traditional zinc plating and hot-dip galvanizing which have serious environmental pollution. It can not only deal with steel, iron, aluminum and its alloys, cast iron, structural parts, but also deal with sintered metal and special surface treatment.


Essential information


Chinese Name: Dacromet process
Application: automobile, motorcycle, traffic facilities industry
Function: processing steel, iron, aluminum and their alloys
Advantages: protect the natural ecological environment

1、 Process flow
2、 Application



1、 Process flow


It consists of degreasing with neutral cleaning agent, surface oxide treatment by shot blasting machine, multicomponent alloying furnace, cooling, shot blasting, passivation, dipping or spraying Dacromet solution, sintering, curing, redox and cooling at about 300 ℃.


2、 Application


1. Auto motorcycle parts


Because the product is a high-speed running vehicle, its parts require good stability, heat, moisture and corrosion resistance. In the past, many parts of Chinese cars were imported from abroad. At present, many parts of Shanghai Volkswagen, FAW Volkswagen, Wuhan DPCA, Shanghai GM, Guangzhou Honda and other automobile companies are processed with Dacromet coating.


2. Metro tunnel, metal parts of light rail, railway and electrified railway


Subway and tunnel are underground, the environment is dark and humid, poor ventilation, rail, screw, bolt, embedded parts, light rail catenary parts are easy to rust, now these parts are treated by Dacromet technology.


3. Metal parts of bridge, highway and port machinery


A bridge, a viaduct, a high-speed railway and a highway are all permanent buildings, with a long-term plan and quality first. However, due to the long-term outdoor exposure to the sun and rain, the metal components and fasteners of corrugated guardrails, viaducts and bridges on expressways will soon rust, which not only needs to tap the paint every two or three years, but also reduces the safety factor. If Dacromet technology coating is used for key structural parts and fasteners, it is not only safe and reliable, but also beautiful and durable.


4. Metal and structural parts for power transmission and distribution


If the stamping parts and fasteners of electrical shell, high-voltage transmission and distribution, urban power supply, tower, pole, metal parts, transformer cover, high-voltage switch cabinet and connection system are all treated with Dacromet coating, although the one-time investment is larger, it is beautiful and durable, and saves a lot of long-term maintenance costs


5. Hardware tools


6. Roof truss structure of agricultural factory greenhouse


7. Solar water heater, satellite antenna, gas, liquefied gas and other metal parts.


In addition to the industries mentioned above, Dacromet coating technology can be developed and utilized in municipal engineering, mechanical and electrical engineering, railway wharf, shipbuilding and ship repair, architectural decoration, aerospace, marine engineering, geological drilling, petrochemical, gas engineering, agricultural science and technology, biological engineering, military engineering, medical equipment, communication equipment, etc.
