The Guangxi Innovation Top 100 is the first regional innovation list released by China. This list has conducted an overall inspection of the innovation ability of Guangxi enterprises, specifically applying for invention patent applications, authorization rates, cited patents and effective utility model patents. The quantity was ranked separately. Yuchai, SAIC-GM-Wuling, Guangxi Power Grid and Liugong Group ranked the top four in terms of indicators. In the future, the "Guangxi Innovation Top 100 List" will be released in the year and continue to focus on the innovation of enterprises in Guangxi.

Yuchai Engine

Since the "Twelfth Five-Year Plan", especially since the implementation of the "second venture", Yuchai has always adhered to the concept of innovation, adhere to the priority of efficiency; based on system innovation, adhere to lean operation; focus on product innovation, persist in doing Specializing in precision; with manufacturing innovation as a support, adhere to the direction of intelligence; marketing innovation as the promoter, adhere to both inside and outside; to the main line of industrial chain innovation, adhere to the upper and lower alliance. As a leading enterprise in Guangxi's manufacturing industry, Yuchai has always been a model of technological innovation. It has led innovation through innovation and has embarked on a road of innovation-driven development with Yuchai characteristics.

It is reported that Yuchai has been awarded the No. 1 patent application by Guangxi enterprises for 10 consecutive years. It was ranked first in the engine industry in 2013 by the “National Accredited Enterprise Technology Center,” and the “Digital and Large Engine Block Digital Casting Workshop” project was selected in 2015. The smart manufacturing specialization in 2015 won the National Science and Technology Progress Award twice.

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
