All About Needles
Processes involved in making a needle
1. Wire is drawn down from 5's gauge steel rod. 
2. The wire is then straightened and cut to 2 needle lengths.
3. Points are then formed on each end.
4. The impression of 2 eyes is stamped into the wire.
5. Holes are then punched through both impressions.
6. The wire is broken into 2 separate needles.
7. Waste metal from around the eye is removed-this is known as cheeking.
8. The needles are then hardened.
9. To prevent brittleness, they are subsequently tempered.
10. The needles are scoured - this removes burrs from inside the eyes and polishes them.
11. The needles are finally nickel plated, inspected, and packaged.
