Increased interest in the production of smaller wire diameters

high-frequency heating systems and proven oil quenching troughs to ensure uniform heat treatment and minimal risk of distortion or cracking when quenching. The mechanical handling equipment on the line includes a quick load pay-off unit, an accumulator for tension control, straightening rollers, three sets of pinch rollers for driving the wire along the line, wire cleaning devices for the removal of drawing soaps and quench oils, and take-up units. The whole system is controlled and monitored by a Siemens software package, providing a result for the customer that is an efficient, repeatable process capable of production speeds of up to 150m per minute.

Typically, the wire processed on these lines is cold coiled into automotive suspension springs and offers better dimensional tolerances than traditional hot coiling. This cold coiling technique gives the coil manufacturer the ability to produce a wider range of spring shapes. Over recent months, Radyne has seen an increasing interest in a segment of this industry – that of smaller wire diameters. This includes wire that is subsequently wound into automotive clutch and valve springs, as an example. As an immediate response to this growing interest, Radyne is promoting its 3mm to 7mm spring wire processing line. With a design based on the standard larger diameter line, this latest equipment uses a combination of modern,

SINCE the mid-1990s, the Inductotherm Group-owned Radyne brand has been synonymous with induction processing of spring wire for cold coiling applications. By offering turnkey solutions, Radyne has built up a leading reference list and an impressive level of knowledge. The continuous IT (induction tempered) spring wire processing lines can be found all over the world, including North America, Europe, China and South Korea. The latest offering is currently on its way to a well-known Indian wire manufacturer, with a production start date towards the end of 2019. As a standard process, this equipment is designed to heat treat a wire size range of 7mm to 17mm diameter and is supplied with a performance and process guarantee.
