Washing machine motor soap extruder

  1. Apr 18, 2012 #1

    I am trying to start a small home business making soap. I am on a really tight budget and also very new to the extrusion process.

    While I may be extruding soap, I understand that the process is very similar to plastic extrusion.

    I want to extrude soap bars using a machine similar to the soap extruder on this website


    However I am trying to make this as cheaply as possible.

    I plan on buying a screw and barrel and then fabricating the rest of the machine myself.

    I am thinking of using a washing machine motor to drive the screw.

    Could you please advise me on the viability of this?

    What size screw and barrel would I need to order from the supplier? I was told that a 30mm or 40mm screw would be best, a 100mm screw would require too much power and would be too expensive.

    Would a washing machine motor be suitable?

    The manufacturer of the screw and barrel asked me what power motor would be used and what are the gear ratios. What should I tell him? I have not told him that I plan to use a machine motor :rofl:

    Any advice would be greatly appreciated

    Thank you

    Tell him the power of the motor and what rpm you plan on running the screw at...
