KPW is a supplier to the medical device manufacturing market, in which precision stainless steels in Grades 304, 316 and 316LVM implant grade are the principal products. KPW specialises in highly polished wire, which can be supplied in cut lengths to exacting tolerances in length, straightness and surface finish.
Through our subsidiary, K.C. Smith Ltd, which is approved by the MDA, we are a major supplier of specialised stainless steels to the orthodontic and medical industries – principally via orthodontic laboratories, dental hospitals and the NHS.
KPW is certified by the MDA, and is authorised to CE mark products.
A major medical equipment manufacturer found that expensive damage occasionally occurred to the special copper alloy windings of the large magnets it manufactured for scanning equipment. To protect the magnet, the manufacturer required to develop a process of overlaying the windings with a protective layer of stainless steel.
KPW produced samples of grades and tempers of stainless steel flat wire. KPW also provided advice on the type and installation of unspooling equipment to be used in the tension controlled process. An additional problem encountered was the difficulty in gluing the protective stainless layer to the main windings. To solve this problem KPW developed an in-house ultrasonic cleaning line to ensure that delivered flat wire was oil and grease free.
A UK medical device manufacturer had developed an innovative blood testing kit which used stainless steel needles. As production of the units increased to meet demand, the manufacturer required a high quality and reliable supplier of stainless needles who would be capable of extending production capacity to meet future requirements.
KPW was well known for high quality and precise cutting to length of stainless steel wire. We converted a CNC cutting line to the exclusive production of these products, and as production requirements increased, added several additional machines over the following year. KPW developed special techniques which enabled the cutting machines to operate consistently at the very top of their production capability, typically 24 hours a day.
