In the production area totally covering 30 thousand m2, about 24 thousand tons of head products are manufactured every year, the powerful production capacity of which has contributed to made Weide a leader in Chinese pressure vessel head industry.

Manufacturing Capacity

Referring to the advanced technique overseas, we have specially developed a set of hand forming equipment, which is the most advanced one in the world. Apart from that, Weide possesses self-designed 6600t, 3000t, and 680t fully automatic double-acting hydraulic presses, 10m, 4m, and 3m cold metal spinning machines, 4.5m hot metal spinning machines, and other supporting equipment and molds. Here, you are expected to find any equipment you have ever seen in the head industry. Weide is competent in customizing various vessel end caps with different materials, shapes, and specifications.

In Weide, we have established a complete head production line. To guarantee the quality of our vessel heads, we purchase stainless steel plates from TISCO, and carbon steel plates from Baosteel. Different techniques such as argon arc welding, submerged arc welding, and plasma welding are introduced to process these raw plates. The 6600t double-acting hydraulic press, whose production capacity is the largest in the world, is able to deal with workpieces with diameter of 3.2m. Our 3000t double-acting hydraulic press is used to process diameter range of 650mm-1800mm. The 500t, 800t and 2000t dishing machines are used in forming large-sized heads and dished heads. The heat treatment furnace powered by natural gas, with an accurately-controlled temperature, is set to remove the stress of heads and enhance their durability. Besides, we have developed independently 3m, 4m, and 10m metal spinning machines, among which the 10m spinning machine is one of the largest ones in the world. Flaw detection rooms are specially set to inspect the finished heads. Finally, we will polish and seal the end caps for pressure vessels according to clients' request.
