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.
