Man! The pressure cooker I use to cast resin just eploded on me! I pushed it to 65psi and BANG! I was lucky to not be knocked-out by the flying cover, or splatered with resin... So my advice for all resin caster wannabe out there: when you buy a pressure cooker, don't get a crappy one like I did. I realy should'nt had cheaped-out on that one, now I know. But has it happened to anyone else? |

I heard of an insurance story where there was a complete failure of a pressure cooker. It exploded killing the poor homemaker and destroying the entire kitchen. |

Simple solution; purchase a pressure chamber designed for casting. Pressure cookers are for food, not high pressure resin casting. Objects placed under pressure can be very dangerous and fail without warning. There are way too many examples of serious injury and death from cutting corners like this. Is your life and health worth the little money you are saving by trying to go on the cheap? Doug |

Many people that I am aware of use paint pots designed for holding paint for airbrushing cars and such. Pressure cookers just aren't designed for that kind of pressure. You can get these paint pots at tool stores such as Harbor Freight. Here's a link showing the sort of thing you're looking for. link |

I had a teacher in the 6th or 7th grade (who also taught me to play AH games) whose wife had that happen to her. She was not so fortunate. No shrapnel injury, but she did get severely burned. |

I'll never forget the day I heard the explosion, and ran into the kitchen. Found my old man sitting in the middle of the kitchen floor, covered in gravy, and holding a pot roast in his lap. Stunned. Should've bled off the pressure before he opened the thing... |

ok , forgive my ignorance, what are you using a pressure cooker for, vacuum casting? |

They're using it for pressure casting. Mix and pour the resin in the mold, then put the mold in the pressure vessel and pressurise. It makes the bubbles smaller. Vacuum casting would be applying vacuum to the mixed resin before paouring to get the bubbles to come out of the mix. Vacuum required for this is significantly more than a Hoover will provide. Need special equipment. Some places do both: mix, vacuum, pour, pressure. Gets most of the bubbles out, then squeezes whats left to insignificance. |
