Our available goods
Double-arch products are used where more movement is needed. If the piping pressure is much higher, reinforced bolts should be assembled together with flanges. Reinforcement layer of the bellows by Nylon cords and at both ends by hardened steel wire rings. The floating steel flanges are drilled according to DIN, ANSI, BS, JIS and other standards.

Our production process quality control
We treasure process quality control, there is very strict operation specification each process, which can ensure the goods quality:
1. We use electronic weigher to weigh the weight of ingredients, the precision of weight is gram. So there is no surplus compounds elements;
2. 1.) By controlling material temperature and mixing time in the mixer machine, we can get qualified rubber mixed composites.
2) The calender process is the more critical phase, large steel rollers force rubber composites into smooth rubber sheets.
3)The rubber sheets produced every day must be finished within the same day, we can ensure no rubber sheet remainder each day.
4) All rubber sheets have passed the test of curometer.
3. Adding adhesion agent in the mixture of rubber and nylon tire cord, then the rubber and nylon tire cord can be adhered together and turn into the integral. After vulcanization, all the rubbers are adhered tightly, it is very difficult to delaminate.
Below is the pictures of plastic sheet combined with rubber and nylon tire cord:
4. In wrapping process: all the elastomer constructions are made by hand-built and machine. After hand-builting, the underneath pressing roller moves along the elastomer body and compact the rubber sheets. There are two main functions of the roller, one is compacting the rubber sheets and making the rubber sheets more bonded, the other one is extruding air between rubber films. So it is very difficult to generate blisters and delamination after vulcanization.
5. After vulcanization, there are 4 inspection processes: first qualified products inspection, trimming, assembling process, inspection for finished goods, if the goods with blisters are found then scrap.
