Syringes and needles

  1. ok, I know how syringes are made (either extruded or molded plastic, probably both...)

    but...

    (dont mind me, I'm thinking deep)

    how do they get the holes in the needles?

    I was looking at a 25g needle... and wondering, is it drilled through, but, the hole is smooth, so thats probably not it...

    plus, would need a really small drill...

    but, it can be stretched from a larger piece of tubing, but, then you'd have a certain degree of occlusion from where the metal hits together sometimes... plus, you'd have bent pieces, as 25 g is very very small...

    so, I dunno...

    I believe most (if not all) hypodermic needles are made from stainless steel tubing that is cut to size and then sharpened. Then it gets bonded to the plastic hub.

    And how is tubing made, you ask?

    AND for that matter...

    How do they make those holiday cookies that come packaged in a tube that have the cute holiday pictures perfectly formed along the entire length of the cookie dough in the very middle? I think Pillsbury makes them. Y'all know the ones I mean?

    Same space-age technology I bet!

    ooh.. that I know... first they make the colored part layering the colors to form the thingie... then, they cover w/ the other dough, then stretch and smooth

    I think...
