Stainless Trivia
Fill in your answer below
Manufacturing Process:
Blanking: The process begins by punching pieces in specific shapes from sheets or strips. These punched pieces are known as “blanks”. Tools made from hardened stainless steel or carbide are used to work with materials such as cupronickel alloys, brass, nickel brass, aluminium-nickel bronze, and ferritic stainless steel.
Rimming: Next, the rimming operation raises the edge of each blank to form what is known as a “coin blank”.
- The process begins with feeding an alloy strip of precise thickness into a blanking press, which cuts blank discs to the required diameter.
- The blanks are then deburred and thoroughly cleaned.
- Edge rimming is carried out to achieve the desired dimensions.
- If required, blanks of different diameters are press-fitted based on currency specifications.
- Each sample then undergoes annealing, descaling, and polishing to achieve the required surface finish.
- Finally, every coin blank is auto-inspected and weight-checked before being bagged and dispatched.
Product Features:
- Each blank undergoes testing for tensile strength and hardness.
- Processes comply with ISO 9000 certification standards.
- Surface roughness is precisely measured through rigorous testing.
- Every blank is tested for bending yield limits to ensure performance in application.
