Product Description

Stainless steel Ultra-high vacuum chamber for film growth


The utility model belongs to the mechanical technical field of vacuum cavity, in particular to an ultra-high vacuum cavity used for film growth. Its main body is formed by cutting eight vertex angles from a cube, and its internal cavity is hollowed out spherically to form the inner wall of the cavity used for film growth.



Company Profile


Our company has two main production plants. Zhangjiagang factory is responsible for the rough forming of workpiece, mainly forging process; 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. Our company adopts the mode of automatic robot welding and manual precision welding to achieve flexibility and high quality
