Edge Welded Bellows andbHydraulically Formed Bellows

Company Profile

Location: China (Mainland)
Business Type: Manufacturer
Main Products: Metal Bellows, Welded Bellows, Hydroformed Bellows

Product Detail

Technique: Welded

Product Description

Edge welded bellows are manufactured by stamping sheets of metal into diaphragms and welded the inside and outside edges of them. Edge welded bellows are remarkable in that any metal can be manufactured into bellows if it can be welded. An especially remarkable feature is that the number of convolutions is theoretically unlimited. The bellows are manufactured to have excellent elasticity and bendability, while retaining high hermeticity in a manufacturing process that requires outstanding technology. Edge welded bellows are attracting attention as a high-performance part which supports the semiconductor, liquid crystal, nuclear power, medical device and other high-tech industries.
