Hi,
I am in the practice phase of heat sealing right now before I dive into making the raft and I have a couple questions about my heat sealing and if I’m going about it the right way. I’m using a Hangar 9 Iron that is definitely getting hot enough, but I’m wondering if it’s getting too hot. I was able to get dial it in to where I know it’s definitely too cold and the two pieces would pull apart easily. Moving the dial a tad higher and I can get everything to seal put when I force it apart most of the TPU comes off in one big chunk with a couple smaller areas that stay on other piece of fabric. This happens when sealing the standard (yellow) fabric to the seat fabric, the yellow to yellow, and then the standard yellow fabric to the 450 floor fabric. Based on the heat sealing technique page my iron might be too hot or I’m not pressing hard enough or holding it on long enough (I did have the other side of the TPU start to melt on the floor piece one time). I have attached some photos of my practice runs.
Any guidance is appreciated! Also, I tried to post this last night but it seems to have disappeared so apologies if this comes through twice.
Thanks!
Aaron
