1.Do you have these Difficulties?
Difficulties | a material that is difficult to shape or form |
not to invest capital to replace worn out machines, retool machines or add capacity | |
using equipment infrequently and can't justify the expense | |
benefit from the reduced machining associated with near net shapes | |
buying from machine shops and find the cost expensive | |
lack the skilled labor to produce precision, high-quality parts or who can't find skilled craftsmen |
If yes,please use Precision Cold Drawn Products
2.Feature and Customer Benefits
