Do you simply want to buy BIZON contacts or housings with press-fit contacts?
Then a license is irrelevant for you.
You simply buy BIZON contacts and the BIZON technology at competitive market prices from the
licensed manufacturer you trust.
If you process the contacts in-house or outsource the production of a plastic housing with press-fit contacts (inserted or injected) to a plastics processor, then you should still take care of the press-fit technology. The contact is only half the story.
What you need is the press-fit connection and you create the other half of the connection during the joining process with the PCB.
Correct processing is just as important as a good press-fit contact.
You will find a lot of information on this page.
Even if you purchase housings with press-fit contacts, careful cooperation is worthwhile. This is because enclosure manufacturers often see press-fit contacts merely as inserts, without considering their function. After all, they have nothing to do with it. The contacts must be correctly supported in the plastic tool and the position must be coordinated with the PCB and the assembly. It is your device that fails in the event of faults.

That's what I made it for.
