China is a big manufacturing country, there are thousands of companies produce and sale metal bellows, but most of them mainly serve the petrochemical pipeline installation companies or end customers. The real factories of exhaust bellows(flex bellows) for engine exhaust systems are extremely rare, and we are one of them. With more than 8 years’ auto racing exhaust industry experience, our company understand the needs of customers better than other companies.
Many companies selling exhaust bellows(flex bellows) are not really a factory, and do not have the capacity to produce. They purchase metal bellows from another company’s existing inventory, then simply assemble, so that the quality of the exhaust bellows(flex bellows) is difficult to guarantee. Some even directly start a resale trade, can not provide effective services for customers.


Italian Tube Expand Technology

Tube expand is very important for both process of internal solid liner and product assembly. Years ago, the liner was formed by hydraulic press with customized molds for every single size. The forming efficiency is very low and the expanded section is always not straight enough, which will affect installation badly. The worse is that, without the help of Italian tube expand technology, we had to assemble all parts together by manual, which leaded to extremely high production cost.
By using the tube expander, the quality of internal solid liner is much better than before, and more than 5000 pcs exhaust bellows(flex bellows) can be assembled within one month. It is unbelievable to us before, but benefits our customer and ourselves now.


Made of 304 Stainless Steel Completely

The current serious excess of Chinese domestic production capacity, and universal equipment serious homogenization, caused vicious competition in the market price, the result is fake, shoddy, copycatting. Many companies sell metal bellows simply with 201 stainless steel instead of 304 stainless steel, and then sold to customers at a price of 304 stainless steel. Therefore, resulting in the current market turmoil, the user can not tell who’s exhaust bellows(flex bellows) is good.
To ensure product quality and user experience, our company do not use 201 stainless steel material for all products. Our exhaust bellows(flex bellows) are made of 304 stainless steel completely, include bellow element, internal solid liner, and reinforcing ring.

NO Any Tooling Cost

We believe that many buyers must came across such manufacturers, the price of exhaust bellows(flex bellows) was only a few dollars, but tooling costs determined to be a big amount of hundred dollars, and some even up to thousand dollars. There are several possibilities of this case. The product inquired is not standardized; exhaust bellows(flex bellows) is not a featured product of these factories; And the worst is that many manufacturers live by unreasonable tooling cost. Because of asymmetric information, a lot of customers pay the high cost of mold for a quite simple product . It is very sad, but before met the right factory you will not understand.
exhaust bellows(flex bellows) is our featured product, and we developed a standard specifications according the majority of market demand. You don’t need to worry about extra tooling cost here, because we do not charge any fee for it. And we saved lot of time of making molds, so that your order can be finished in a shorter period of time.
