Precision Wire Stranding and Bunching - Knight Group

Stranding & Bunching

Your Material Your Way

Available in wire

Knight Precision Wire has assembled a range of tubular stranding and bunching equipment, capable of producing stranded wire ropes and bunches in stainless steel, nickel, nickel chromes, copper and aluminium.

Wires can be stranded from annealed or hard material, in a variety of constructions, with pre and post forming to ensure the strand is tight and runs straight without twist. Strand can be manufactured to resistance and set spool lengths or as cut lengths as required.

For applications that require annealed strands, the finished strand can be annealed using the strand annealing lines.

The bunching equipment enables bunching of soft materials, most commonly copper and aluminium. Our machines can produce bunches of 120 end, of 0.007mm wire, up to the largest size of 30 end, of 0.8mm wire.

Knight Precision Wire offers a variety of wire services and can provide free quotations on your requirements. Please get in touch to arrange this.
