    Bladder molding pressure, resin viscosity and mold sealing...

    Thank you all for your much needed help. I tried different curing heat and temperature profiles without any success, before giving up on the Meguiars wax. I replaced it with Frekote NC700 and all my problems are history :) It seems like the highly polished mold just wasn't rough enough (!) for...

    Bladder molding pressure, resin viscosity and mold sealing...

    Thanks for your great replies guys. Sjamesp, I took you advice and took the simplest solution first :) I've managed to solve the resin loss problem by increasing the cure time at a relatively low temperature to get the cure going somewhat, before I then increase the temperature to finish the...

    Bladder molding pressure, resin viscosity and mold sealing...

    Thanks for your reply, Yes, you are correct, I'm using the slight mismatch for the air to vent out as I inflate the bladder. As I believe is customary in the bike industry (from what I've seen). But my gap seems to be slightly to big. I was counting on a mismatch big enough to let the air out...

    thread327-166041 Hi all I'm working on making a carbon fiber mountain bike fork, to a large extent by bladder molding, and I seem to be loosing to much resin out in the flash. My mold is a CNC'd aluminum sandwich mold and I don't have a bulletproof 100.0% fit between my two sandwich parts...
