My first attempt at injection molding with PETE plastic (Mountain Dew bottles). The molded part is the shape of a fishing lure (crankbait). This type of fishing lure needs to have a buoyant body to keep it upright in the water. The PETE plastic used in the video is more dense than water so it is not a functional lure.

    Someone needs to start a MakerBot-IPM company. While 3D printing is great, there are some things for which injection plastic molding are much more suited.

    very impressive setup for the small shop! i need one.

  • JanA

    That’s a pretty impressive project from plastic bottles… :)))

    great work! if you want a machine that is still small but capable of making a part every few seconds you should buy the machine I have on ebay.

    Interesting video.

    I would give you 10 out of 10 for your first attempt at injection molding with PETE plastic. I truly believe that your future attempts would give you more success.

    I would also say that this shared set up is an impressive setup for the small shop!

    Seems like an interesting video. I would like to point that prototype injection molding is the next best thing for companies that do not want to spend too much in production.

    Congratulations on bringing injection molding into your own home! We’re an injection molding company, so it’s great to see some interest outside of our facility.

    I think this is such an initiative and more over you have shared the video which will for sure help the lot of people to get along with the same well.
