PRECISION metal parts manufacturer Fotofab has highlighted customised photochemical machining processes as an environmentally-friendly method of working with metal.
The current focus on the environmental impacts of manufacturing is driving companies to adopt processes which minimise hazardous waste and reduce scrap.
According to Fotofab, it has re-engineered the photochemical machining technique, which uses an acidic solution to get metal parts from sheet metal.
The company has eliminated the use of Trichloroethane and Methylene Chloride which it says are dangerous and harmful to the environment. These chemicals have been replaced with aqueous solutions containing Ferric Chloride, which is used by water treatment plants to clean drinking water.
The manufacturer also claims the wastewater from the process is cleaned of hazardous waste before being released from the plant.
