Company Profile
DRACHMA (ZHANGJIAGANG) MATERIAL CO.LTD has two main production
plants. Zhangjiagang plant is responsible for the rough forming of
workpieces, mainly forging process; While Hangzhou plant is mainly
responsible for precision machining, welding and inspection of
products. We implement this layout mainly to use the industrial
advantages of each region to achieve maximum economic benefits.
Traditional processing enterprises often do not have such ability,
the lack of blank forming ability is unable to achieve the optimal
use of materials, resulting in excessive processing allowance, long
cycle, high cost. Zhangjiagang is located in the southern jiangsu
province, which has the strongest forging capacity in China. It has
a good supporting industry and can realize the diversified
production of forging and pressing blanks. Thanks to this, the
product cycle of our company is faster, the cost performance is
higher, and the forging products have better mechanical properties
than the products directly processed by rod or plate.
In addition, our company has strong welding ability, which can weld
and assemble parts to achieve system delivery. We adopt the mode of
automatic robot welding and manual precision welding to achieve
flexibility and high quality.
