DIY Plastic Parts

I’ve got one word for you. “Plastics” Yes, it’s what whales and seals are having for lunch.

There is an updated video of this, now WITH AUDIO!!! Here is a quick fly through of how to make a plastic injection mold by using Solidworks. First you can see that I am making a simple solid, make sure that it has ample draft. The radii are un important but aids in presentation. Second I am shelling the object to a suitable thickness, remember with plastics a consistent wall thickness is key! I then make a sketch that will define the limits of the mold itself. Next I am defining the parting line, this is the line that Solidworks uses to define the separation of the mold cavity and core sides. I am also turning on draft analysis to help show me that my object is of suitable geometry to part. After that, you cant see it, but I check for shut-off surfaces; I have none. Then by selecting the parting lines I can then create a parting surface, this is the surface that the mold cavity will shut off against when closed. Once those steps are completed I can define my tooling slip, I choose interlock and the approximate thicknesses of each mold half. From there I move each half apart to reveal a mold! When all the steps have been done save the cavity and core sides into seperate files. Next CORES, SLIDES, AND LIFTERS!

    More Beer only please:) I found your video looking to make my own volume pot dials but as it turns out I am able to use a plastic anchor and it works great ,so no need to make anything now.

    … I FILL YOU UP! :)

  • submarineboat:

    Thanks for the update amigo.

  • MGkings:

    RED SOLO CUP ha ha Good video thanks.

  • titanrain1:

    Ebay has no results for “dascar plastics” or even “dascar” anymore. However the user “specialtyresins” has some that looks to be in the exact same container and shows the same off color white plastic. $45 + shipping. Searching for “Casting Resin” and narrowing the results into the “Multi-Purpose Craft Supplies” will get you several other choices too.

    Largest I’ve done was a cool wipe container with an underwater speaker inside and that was no problem. It does shrink. I destroyed a relay trying to encase it in one pass. And it gets very hard. Once it’s cured it’s just short of being as hard as aluminum. –Doug

  • jallenmorris1:

    Awesome video. How thick can you make it and how hard does it get? (I’m also from Oklahoma)

  • watzupdawg:

    Two parts, one cup.

  • AdamTheGuitarHero:

    Cool, thanks bro.

  • submarineboat:

     Yes. Works great with silicon molds.

  • AdamTheGuitarHero:

    Are these Dascar Plastics good for moulding?

  • submarineboat:

    Just go to ebay and search for “Dascar Plastics” –Best of Luck

  • upcycle:

    what is the name of the liquid plastic u r using here? And where do u buy it (get it) or recommend to get it?

  • mdc2296:

    ok where do you get it can you get it at a hardware store?

  • submarineboat:

    Glue’n hose n ware. Or you can make artsy-fartsy little junk, but submarine part are much cooler.

  • mdc2296:

    what do you use this for?

  • misteRoboto1:

    Love it, Soliworks is a powerful tool if you know what you are doing. This is obviously not a demo of the CAD, too quick, no details (all due respect). The mold process discussed loos to me like injection molding, a very, very complex and difficult job to do right from A to B plates ad all in between . BUT he has you guys fired up. Well done. Here’s Solidworks on a vacuform molding process…

    :(

  • dgwbuildwright:

    ” put your pullover on it’s cold outside”.. “its not a pullover it’s a jumper”… petulent twat.

  • capnthepeafarmer:

    CAD packages don’t draw the tools, engineers draw them. Very misleading comment. 😉

  • dgwbuildwright:

    cad packages dont MAKE tools. toolmakers make them. cad just draws them. very misleading title

  • capnthepeafarmer:

    I understood what you wrote. The only thing I can do to make it easier is to make another video. So sit tight.

  • noronhal:

    I don`t think you still followed what I wrote.
    sorry for offending you.

  • capnthepeafarmer:

    It is probably best to not appear as an idiot, when calling someone else dumb.

  • noronhal:

    are u dumb or what. what he said was correct. way too quick and no narration.

  • jettpax:

    It would make more sense to people like me who are still learning if the instruction came in the video as you are doing it.

  • capnthepeafarmer:

    was the description not enough?

  • jettpax:

    Way too quick. Please explain what’s going on.
