The spraying system is optimally adjusted for the work pieces and is also effective in rinsing off solids such as swarf. After spraying, the solvent is pumped directly from the cleaning chamber for recycling ready for the next load. Solvent vapour is directed into the working chamber where it condenses on the cold parts, degreasing even the most complicated of shapes with the smallest of drill holes.

A regenerating carbon absorption system removes the last traces of solvent from the chamber prior to finishing of the cleaning cycle. For adherence to the legal regulations, the system is equipped with a concentration measuring instrument, which monitors the solvent concentration in the working chamber at regular intervals. Only after falling below the concentration value legally designated of 1 g/m³ of air is opening of the sliding door possible. If the activated carbon of the adsorption unit is saturated with solvent, it can be regenerated automatically by hot air in operation with the circulating air.

ISO 9001:2000-accredited Amfin emphasises quality and fast turnround in providing an extensive range of surface treatments, including various plating and anodising processes, painting/coatings, plasma spraying and abrasive blasting, for aerospace and general industrial applications. This production capability is matched by a firm commitment to environmental considerations, with Amfin also accredited to ISO 14001:2004.

The Nuneaton-based company has numerous approvals from leading aerospace companies, among them Rolls-Royce, Airbus UK, BAE Systems and Goodrich, and, while specialising in bespoke and small batch work, has the capability to handle the longer runs and repeat orders typical of volume production.
