I assume the pins go through holes on the board?

How about manufacturing an new tip for a heavy soldering iron?

Take the soldering iron up to a temperature somewhere between the Tg and 
melting point of the material, probably about 150 deg c but you'll get 
the details off Matweb, and push the heads flat. A bit like riveting.

Regards,

The red arrow marked pins (actually 5 of them, 2 not visible) traverse the PCB and are then melted on the bottom, in order to immobilize the part. This acetal melts pretty easily when heated with the heat gun, but due to high volume and process consistency we would like to find another solution.
