Elastic ring for holes, elastic ring for shafts - The main differences between type A and type B are as follows;

 

1. Different shapes:

 

Type A is made by plate punching and cutting process, with A square or rectangular section. B type system is made by wire punching and cutting technology, with a circular section.

 

2. Different production techniques:

 

Type A is made by plate blanking process, type B is made by wire blanking process.

 

3. Different costs:

 

Because type A is stamped sheet, after such A circle, the middle part of the circle is blanking waste, more difficult to reuse. And B model is wire product, want only "wind around" such a circle, did not waste material, so at present B model is used more, because B model consumables material is little, the price is inferior. So the cost of type B is lower than that of type A.
