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.

  1. 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.

    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.

  5. 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.

    This is a very helpful post for the plastic molding, i hope this is really helps me to complete my project.

    Very well explained! It is going to be very useful especially for the first time users.
