A high-precision process will often call for exacting materials choices. Avimo Thin-Film Technologies' electron gun system, which applies films to substrates under vacuum, to form mirrors and filters, is very sensitive to blockages in its cooling and heating systems.
Avimo turned to Durapipe to solve its materials problem. The answer turned out to be a system made from ABS pipes. ABS won out because the pipes, fittings and valves can be made with very smooth inner surfaces, which reduces scale build-up and resists abrasion.
