Just wondering what you think

    Injection mold design is part of the fast paced world of injection molding. When working as a mold designer, you must be able to develop new ways of doing things, and you must be adaptable and willing to learn new technologies.

    Could you please tell me if, among molded components, apart from plastic, there are also other materials?
  • sirkeystone Sep 9, 2011 @ 9:09 pm | delete
    Do you mean, like polymer rubber, glass, or metal? All of these can be used in the particulate molding process, but of course each one has different techniques. Rubber would have to have a solvent rather than heat. Glass and metal work nearly exact but have varying temperature variables. Then there is vacu-forming, which you might even be able to add carbon or glass fiber to this list.

    Fascinating- great instruction, I will have to try molding plastic! Very resourceful lens!

    I'll pass this onto my hubby, who's interested in using plastic molds for making halo armor.

    This is fascinating! I try to limit my purchase of stuff packaged in plastic, because the waste upsets me so much and I know that only a limited percentage gets recycled. The processes you describe here add an interesting option to the menu.

    Great lens to encourage us to recycle plastic containers. The problem I have is in figuring out how to paint plastic automotive parts on my old GTO so that it sticks. I have been experimenting with smaller parts.
  • sirkeystone Dec 7, 2010 @ 7:59 pm | delete
    I should make a lens on this too. Automotive plastic can be tricky as most of it is urethane. From bumper covers to suspension parts. But the kind of parts you are talking about are likely standard poly. The idea would be to rough the part with a decent sandpaper, say 240 grit, then use a self-etching primer. I would not recommend just buying a typical spray paint for the coloring you are talking about. The Krylon polytech type paints have the self etching and a flex agent already added. The flex agent is a must because the paint will have to expand and contract with the plastic's heat/cooling cycles. Hope that helps!

    I can see where this would have a lot of worthwhile applications . . . not to mention - ART!
  • jennynazak Jan 23, 2011 @ 8:11 am | delete
    Absolutely! I've experimented with re-USING plastic (mainly clear stiff plastic housing that toys and electronic goods come in) using it to "laminate" my drawings or make greeting cards out of, but actually recycling the plastic by grinding it up into pellets or shavings, which are then molded, certainly has possibilities for us artsy craftsy folks!

    Very interesting and informative.
