Conclusion

A pre joining process in the production of Bi-Metal collect or coins has noadvantages !

Production results for the customer are more cost-effective in joining & coiningthe 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 .
