During the practical session last week in Rotterdam, we thoroughly tested the new PTFE (Teflon) glue molds. And with excellent results. The samples fit perfectly in the glue molds and after curing, the samples are easy to remove from the molds. Sometimes with just a light push of the finger from the bottom.

The glue molds were subsequently tested for two hours at 150 degrees C, completely stacked with test plates and fixation weights. Notably, the PTFE glue molds showed no noticeable loss of stiffness at that temperature. When measuring the glue molds precisely after this heat treatment, no noticeable dimensional change occurred.
