Profile: Charles Day (Steels) Ltd. specializes in profiling and cutting operation development, design, and production. We are a BS EN ISO 9001 : 2000 certified company. Our flame cutting offers traditional profiling with cutting capacity of up to 270 mm. It is multi-head cutting with accurate in-house programming. Waterjet cutting is a process used to cut materials using a jet of pressurized water as high as 60,000 pounds per square inch (psi). This is then passed through a diamond or sapphire nozzle, which creates an extremely fine bead of water, which will cut through soft materials. Plasma arc cutting uses the plasma as an electrode to transfer a electrical arc to the work piece. The heat of the arc melts the work piece, and the force of the plasma & shield gases blow away the molten metal to cut the work piece. Flame cutting consists of a number of cutting processes used to cut metals by means of the chemical reaction of oxygen with the base metal at elevated temperatures. The required temperature is maintained by a flame obtained from the combustion of a specified fuel gas mixed with pure oxygen.
