Due to the ongoing miniaturisation in industrial sectors like automotive, electronics or medical, the development of new manufacturing processes which are suitable for micro system technologies gains more and more importance. The miniaturisation of components leads to challenges in the manufacturing of micro parts. One application area is the manufacturing of moulds for the micro powder injection moulding (μPIM) process. This process requires good surface qualities and a sufficient demoulding behaviour of the moulds. Micro milling, micro electrical discharge machining (μEDM) and micro laser beam machining (μLBM) are appropriate processes for the manufacturing of micro structures in different materials. Abrasive micro peening can be used for further precision treatment. Depending on the desired structure a single process or the combination of several processes has to be chosen to obtain superior surface qualities of the moulds. This paper deals with challenges and limits of the manufacturing processes among others exemplified on a gearwheel mould.
Development of a Cleaning Validation Method for MICRO® A07 Citric Acid Cleaner Using HPLC-CAD
AbstractA high performance liquid chromatography (HPLC) method with a Corona Charged Aerosol detector for the cleaning validation of MICRO* A07 Citric Acid Cleaner residue has been developed. The pooled average repeatability of 3 replicates at 6 concentration levels expressed as RSD was 1.3 % while the pooled average intermediate precision (intra-day repeatability in 3 days) of 3 replicates at 6 concentration levels was 2.4 %. Simulated maximum allowable carryover (MAC) was calculated by using 10 ppm of MICRO®...
Steel Fire Sprinkler Tank Inspection Case Study
These images show the steel fire sprinkler tank before any preparation work and then after preparation. The steel fire sprinkler tank was fully relined with Acothane DW. A Logistics company in Berkshire recently had an R.O.V Inspection carried out on their Fire Tank, we also provided them a sprinkler tank maintenance. The sprinkler tank inspections confirmed significant amounts of corrosion to numerous areas of the internal substrate. The overall size of the fire sprinkler tank is approximately 9.2m diameter x...

The challenge of safety and health in micro and small enterprises: what can be done?
A high-level policy seminar, ‘Micro and small enterprises (MSEs) in Europe: How can we make sure they are safe, healthy and productive places to work?’, was organised by EU-OSHA in Brussels in June, with representatives from the European Parliament and the European Commission, social partners and other key actors and academic experts. Discussions focused on how to ensure the health, safety and well-being of the millions of European citizens who work in MSEs, as well as the role of MSEs in the...
