Welded ring and custom-form wire made to the customer's technical drawing, mainly for automotive and industrial applications. The ring block wire we produce is mainly used in heavy commercial vehicle bellows. Precision series production on automatic spot-welding lines.
Ring block wire is a wire part made by bending low-carbon steel wire into a ring or a customer-specific form and welding its ends. The ring block wire we produce is mainly used in heavy commercial vehicle bellows.
What matters most in these parts is dimensional consistency: the ring must fit the part it is mounted on to the millimetre. That is why every form at Quarco starts from the customer's technical drawing, and wire diameter, bend angle and weld point stay true to that drawing.
Figures apply to standard production; lead time and quantity for custom forms requiring tooling are set per project.
From rings to custom forms, every part is produced to the customer's drawing.

Welded ring and custom-form wire. 3 – 8 mm diameter, copper-coated; series production to the customer's drawing.
Every order goes through the same disciplined flow, so the first sample and the series part are identical.
Dimensions, tolerances and quantity plan are derived from the customer's drawing or sample.
Form, bends and weld points are modelled digitally; tooling or fixture needs are defined.
Copper-coated low-carbon steel wire is prepared to the length the form requires.
Rings and customer-specific forms are shaped on bending machines.
Joints are joined by automatic spot welding with the same strength on every part.
Every batch gets dimensional inspection, weld-strength sampling and visual inspection.
Automatic spot-welding equipment, precision bending machines and experienced wire engineering.
± 0.5 mm tolerance to the customer's drawing; CAD/CAM-supported welding lines.
Durable joints through automatic spot welding; suitable for load-bearing construction.
Tens of thousands of units per month; reliable supply for high-volume OEM orders.
