All frame work was mig welded and made from either 2"x2" tube or 1"x2" steel tube.

Step 1: Welding Frame Top

Step 2: Welding Frame Bottom

Step 3: Welding Frame Bearing Support

Step 18: Main Frame Done

Step 19:

Step 20: Heat Shield Installation

Step 21: Sheet Metal

I covered the walls by welding sheet metal to them.

Step 22: Insulating

I insulated it with compressed rock wool that I bought from the hardware store

Step 23:

Step 24: Exhaust for Excess Heat

Step 25: Fibre Glass Door Seals

I used high temp silicone to glue the seals onto the frame this helped the heat stay in.

Step 26: Insulated Machine Ready to Run

I used a 1750rpm motor and a 50:1 gear box , the unit is heated by a diesel space heater that brings the internal heat to 400 deg F in about 10 min .

Step 27: 50:1 Ratio Motor and Gearbox

Step 28: First Part Out of Machine

This part used 5lbs of low density poly ethylene pellets at 400deg F for about 40min heat time and 10 min cooling time .

Step 29: Part

Step 30: Finished Part

    Question 2 months ago on Step 1

    This is very practical and we would like to go for our project. Is it possible to get design details of the same.


    Answer 2 months ago

    I build this unit a long time ago but i will probably be remaking it on my YouTube channel with more details of the build thanks my YouTube is bonifabcustom

    Very impressive!
    What do you make the molds out of? I presume with the bottle, you started with a pre existing bottle (Header tank?) as the positive?
    This could be useful to leverage 3D printing to make things like elaborate plastic inlet manifolds - and many other automotive components.

    Wonderful, amazing. but still require more details like how much hp motor, and which company made greabox, wiring and all that stuff. But still amazing. Thanks a lot.
