Medical IndustryTooling for the medical sector are usually small and complex with critical sizes and perfect shut off faces, the smallest flash on a component and the parts are rejected. Even the best made tools require minor alterations after the first tool trial and laser welding is the way to tackle it. Accurate amounts area applied just where it is required. With minor rework the tool can be off to the customer with the minimal of fuss and cost to the toolmaker. Old or damaged inserts can be welded and re-used as many times as is needed, saving costs on making replacement inserts and high costs for delaying production. Medical equipment can be welded to fix assemblies together or to fill in bug-traps that could lead to contamination as bacteria grows in the creavices. Precision ComponentsMetal components manufactured to a high tolerance can become too expensive to scrap if they are found to be out of tolerance upon inspection. Laser welding is the only way to return these components back to their required dimensions, the quality of the repair is so accurate that the welded area is invisible after re-working. Even expensive small press tools inserts made from brittle materials such as M2, D2 Vanadis can be welded and re-dressed. Press ToolsEMP Tooling can repair fully hardened tool punches and dies, forming tools made from materials such as D2, M2, A2 and Vansdis. Many press tools manufacturers do not like welding brittle materials as this can cause the tools to crack. Laser welding enables us to build up damaged, rolled or worn edges and even build up large areas that have broken off. Tools that have cracked in half can alse be re-welded back together.
Blow MouldsMoulds made from aluminium and stainless steel can be welded, damages on slit edges, cutting lands and knife edges can be welded and dressed back ensuring the mould continues to produce flash free product. Even engraved features on the bottle can be welded and re-engraved, saving the toolmaker the nightmare of welding aluminium using conventional tig or even the bottle mould be remade due to the problems associated with welding aluminium especially when it is an old bottle mould and many impurities have induced themselves into the surface of the mould. AerospaceAll aerospace components require high precision and quality. HIhg grades of stainless steel and titanium can be laser welded whether it is damaged area or an out of tolerance part. They can all be welded and re-machined. Rotational devices jigs and fixtures can be used in conjunction with the laser welding to ensure repeatability of welding on batch work. Conventional tig or mig welding has made many designers nervous about welding aerospace components, especially if they are made from titanium and risk of scrapping them at the welding stageis high. Thin sections can be easily welded wiht no heat discoloration, sinkage, distortion or crackinh. We currentlywork very closely with aerospace laboratories proving many test pieces for hardness testing, x-ray and heat treatment strength tests. Even components that have been treated and then welded and repaired has been shown that the laser welding process does not affect the heat treatment process - and causes no stress in the component. Laser welding is the only option for aerospace components and is second to none.
