Hi,
I have a question regarding heat sealing the tubes to the 1000D fabric.
I’ve notice that air bubbles like to form after I’ve sealed the fabric and left it to cool – 10+ minutes afterwards. So I’ve been placing a piece of timber with some weights and leaving it.
This seems to minimise the bubble formation. Then I heat / repeat over and over. I get to the point where I think well a couple of small bubbles shouldn’t be an issue?
Just wondering if anyone might have any suggestions?
It is the different weight of material – differential expansion with heat?
Is my iron not hot enough? I built a temperature controlled iron out of 3D printer parts, it uses a bit of flattened copper pipe, 30W heater cartridge and a thermistor to monitor temperature. Basically I can set it to a temperature and it will be computer controlled.
I bumped it up to 215 degrees – should I go higher? It seems to require a lot of heating to bond the floor. What temp will the fabric start to melt?
Regards
Aaron
