South Korea increases investment in OLED lighting industry

Recently, the Korea Ministry of Industry, Commerce and Resources announced that it will launch an OLED lighting industry support program called the OLED lighting industry cluster construction project, which will be launched at the end of September 2014 for a period of five years with a planned investment of 22 billion won. 1.33 billion yuan). South Korea plans to promote industrial development and enhance the global competitiveness of the industry through the supply chain network of the upstream and downstream of the OLED industry. The project covers OLED materials, light sources, components and modular systems. To encourage the commercialization of OLED products, the project also supports the testing and evaluation of OLED lighting technologies and products, while setting domestic and international standards, including the performance, safety and evaluation of OLED lighting products. In addition, the government may increase the project investment by about 25, which means that the total investment of the project can reach up to 30 billion won (about 181 million yuan). Of course, this depends on the number of participating companies.

Cold Drawn Steel Bar

Cold drawn steel bar is produced by Hot Rolled Steel Bar or wire rod to get smooth surface, more precision size, higher mechanical properties, which improves machining characteristics. It can also get various sections and sizes. So cold drawn steel bar is a better choice for machining users.

For high carbon steel or alloy steel bars, to avoid the cracks in inner or surface, the bars are usually required to be annealed before cold drawing.

To get different mechanical properties or hardness depending on final usage, the cold drawn bars will also be heat treated such as annealed, normalized or quenched and tempered(Q&T).

For CNC machines usage, to get much more precision sizes or much more better surface roughness for chrome plating, the cold drawn steel bars can also be centerless ground or polished.

We have more advantages on producing cold drawn steel bars:

1) Big stocks of hot rolled round bars or wire rods as raw materials

2) Wide range of cold drawn steel bar sizes: from 10mm to 150mm

3) Different cold drawing medias powder or oil to get different surface

4) Straightening machines to get better straightness up to 0.5mm/m

5) Grinding and polishing machines to get better roughness upto 0.4um

6) Heat treating furnaces to adjust the mechanical properties

7) Full sets of testing equipment to test the sizes, mechanical properties and microstructure.

8) Multiple packages to avoid broken packages and anti-rusty
