this is machine is a kind of  mechanical equipment  matching the metallic spiral wound gasket . it is a non-standard special equipment  used to produce strengthen ring of  metallic spiral wound gasket.
Firstly, this equipment can reasonably overcome the difficulty of producing strengthen ring with larger diameter and change the previous unreasonable producing craft. In this case, neither do you need to buy large lathe nor do you need to install clamp in it. By this way, you can reduce your investment on large lathe and its accessorial equipment. This machine still has the ability of producing gasket with larger diameter.
In the second place, this equipment has changed the primitive craft and improved the efficiency as well as the availability of the raw materials thus you can save raw materials and reduce the cost. Take the strengthen ring with diameter 1000mm, single side width of 50mm for example:
If produce by a lathe, you need some fittings and make some adjustments to the machine. Under this circumstance, the productivity is low; the production cycle is long. In this case, produce the strengthen ring costs both money and time greatly. We just make use of 20% of the material if produce by the Lathe. The larger the diameter is, the less we can make use of the materials. (Because the strengthen ring is produced from the square-shape materials).
However, if you use the ring bending machine without using other fittings, the efficiency is as about 20 times as using the large lathe. We can make use as much as 98% of the materials with this equipment. It adopts the good craft on the basis of reducing the investment and saving the cost, so it can reduce the cost of strengthen ring as much as 90%. This machine, which can guarantee the quality of the products completely, is an ideal machine for producing the strengthen ring of the metallic spiral wound gasket.
