Conclusion
A pre joining process in the production of Bi-Metal collector coins has no
advantages !
Production results for the customer are more cost-effective in joining & coining
the product in one production cycle.
(simillar as in the circulation money production)
Lower cost value, as the pre-joining operation is not necessary.
The end-product result is much easier to control and to influence.
Tool cost is reduced.
The production flexibility with a Bi-Metal feeding system is unique on a TMP .
