Alternative Methods to Die Casting :

  1. May 30, 2009 #1
    Anyone knows of any alternative methods ot fabricate a Copper-Berrilium / or Copper-Nickel / alloy into a small tubular form (Custom design)...

    I need to Mold a Copper Alloy with the following dimensions : Precision required.

    http://www.fileden.com/files/2008/4/23/1880222/Copper%20Tube%20Fabrication.JPG [Broken]

    R1 = 5mm
    R2 = 6.5mm
    L = 40mm
    Rc = 3mm

    (tip of this part is conical, and Closed, hence radius of this Hemisphere end Rc )

    And that's it. But i need a maximum of 20 Pieces of this part. So i cannot go for Die-casting. It'l be way too expensive for me... Does anyone know of any other methods to fabricate this in Copper - or any of its alloys?

    I need it for Heat-transfer applications, which may involve rapid heating and cooling of the part. What is the best way to do this? and the cheapest. cuz, i dont want high volume. only high precision.

    Please suggest.

    I was going to suggest a lathe, and reaming, but that's after mistaking your dimensions as cm. If you have access to a machine shop / good machinist you should probably talk to them and see if they might be able to help you. On the other hand, you'd probably be able to braze a hollow semisphere onto the pipe, but that might impact your intended use:

    If you can get it in bar stock you shouldn't have a problem machining it.

    lost wax casting ?
    good enuff for jewelry

    Not sure but in the past, these guys have given us detailed help with lost wax / http://www.deangroup-int.co.uk/" [Broken] queries. May be try giving them a call?

    i have used rapid casting in the past and that is good for up to 50 off depending upon the tool. Quite a small part so shouldn't be too pricey. whats your budget?
