We are getting more & more cycle tops to sub, and have historically been nervous around plastic zipps ...... but should i be?
They are MoreMiles tops with the micro plastic zip covered fully by tiny cloth flaps.
Either i have to use my hat press twice to do both sides, - or can I use big heat press and do both in one?
Will the zip melt at 190c ?

I sub on 170-180C max. never at 190 so not sure. But on my temperature never had malted zips. Melting point of plastic is much higher then we think.

Top tip Paul, how long at 170-180c ?

60-70 sec. never tried more then 70 max. but i know some people go as long as 90.

if they are a problem get a new rubber base and cut a zip recess in it, just deep enough for the zip, you can then lay the garment across, and sub over the top, - mark used a dremel type tool to sculpt a groove out in mine

Pressing the zipp worked out great, so thanks for the tip.
