How can I quickly and accurately form batches (10 to 100) of parts from mild steel wire about 3mm diameter ?

The parts are 3D with bends of several radii, about 200mm in the longest direction with a 0.2"diam 270 degree loop in one end for a bolt.

    $\begingroup$ Are you able to post pictures of one of the parts? It may be easier for those small batches to 3D print out a negative mold and cast the parts. $\endgroup$

  • $\begingroup$ Yes here are handmade versions the two parts connected with a screw pivot. $\endgroup$ Jul 26 '18 at 18:25

  • $\begingroup$ Yes it's mostly very expensive. $\endgroup$ Aug 1 '18 at 19:05

A CNC bender would be the way to go for quality and repeat ability. Otherwise, you can try building some bending jigs to try and replicate some of the bends between pieces better.

  • $\begingroup$ Thanks. This confirms what I decided to do. The problem was it was hard to find a CNC bender who could bend wire with features as long as my part, wire as thin as I needed, and would make small enough quantities. After an extensive search I found a few and will go with Western Wire Products Company, Fenton, MO. They can make 10 for prototyping for 500 dollars but can make 1000 for around 1000 dollars. Much easer than making them myself. $\endgroup$ Aug 9 '18 at 13:58

Round nose concave pliers have too little leverage.

The Du-Bro E/Z Bender's great.

  • $\begingroup$ @OpticalResonator Good point, feel free to paste screenshots into the answer. $\endgroup$
