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
