The process has two steps:

– First we melt the river head with hot air (the air temperature and the mass flow are measured)

– Second we depress the rivet head with a heated riveter.

The advantages of the process:

• Strong shape lock binding – the melt will fill out more than 90% of the hole
• There won’t be cracking on the rivet material even with filled plastic
• The rivet won’t become sensitive for vibration
• Ecstatically smooth rivet head can be made

We ensure the stability of the process with

• CFD flow simulation for the air nozzles, and heat simulation for the hot press heads
• Controlled air mass and temperature
• Heat sensors for the PBC surfaces against overheating
