Hairpin assembly machine
Custom hairpin assembly machine for bobby pins and hair clips. Feeding, assembly and packing stations set to your output. Send a drawing for a quote.
What this machine is for
This machine handles hairpins: the conductor is cut to length, bent into a U and positioned for the next operation, with leg length and bend radius held to drawing. Feeding a long, thin conductor without kinking it is the part of the design that decides scrap rate.
How the line is built
Components are loaded manually onto two vibration discs. Eight jigs cut from die steel carry each hairpin through the pushing and rotary cam stations, so the bend and the leg length are set by the tooling rather than by the operator.
Control is a Delta PLC with a Wenview touch screen, with a safety grating and guards on the moving parts.
