OK guys, heres a puzzler for you all.
heres what were making:
http://hydroflexskateboards.com/
we have been making composite skateboards now for a few months. I have been CNC-ing the prototype molds out of corian countertop material and other similar materials. These materials are acrylic based, filled with stuff (limestone, i think?) and whatever dyes and color chips to attain the desired aesthetics. these molds are doing great as prototype molds and should last for a couple hundred parts before they start to get too beat up to use, even then ive been able to patch them and get more life pretty easily.

so to assist in the marketing aspect of this new line of boards, we tried to think of a way to make the infusion process more interesting to the potential market. i thought of making a clear mold out of clear acrylic. i did, and besides being more difficult to machine and more difficult to sand/polish, it went well and the mold looks great. we did an infusion, everything went great, the videos look great, pictures too.
BUT - and heres the problem/question:
the parts stick terribly in the mold, and there seems to be a hazing effect after demolding. we are using the exact same mold release wax as we do on the corian molds, 6 applications on a fresh mold and 1 application after every shot. we have done 2 shots with this mold so far. the first time the part stuck pretty bad and left enough haze to where i decided to strip the mold and re-polish it. then we waxed it 8 times, and tried another shot. we demolded it but it was still very difficult to get the part out of the mold, and it hazed again.
anyone got any advice as to why these 2 acrylic-based materials release differently from eachother with the same release wax and process? is there a different mold release i can/should be using for a clear acrylic mold?
any help or advice is very appreciated. i hope you guys like the video too. there should be a better one somewhere on vimeo very soon, ill post a link
thanks
