Precision strips are formed via a cold rolling process & they offer attractive features such as:
The major thrive is to ensure defect-free strips, exhibiting low material property variations from the center to the edges of the strip. These can be manufactured in different grades depending on the desired application.
Jindal Stainless has been supplying stainless steel coins blanks to the Indian and international mints for making coins. The Company has the capability to produce high quality stainless steel and non-ferrous coin blanks. The present installed capacity for coin blanking is 10,000 metric tonnes per annum.
Blanking: The process involves punching pieces in specific shapes from sheets or strips. The punched-out piece is called the “blank,” hence the name “Blanking.” It is most often performed with tools made from hardened steel or carbide, which work on metals like Cupronickel alloys, Brass, Nickel Brass, Aluminium- Nickel Bronze, Ferritic stainless steel, etc.
Rimming: The rimming operation is carried out to raise the edge rims on the blank to form a “Coin Blank”.
