Milling and Phosphating Plants
Galvatek’s etching, milling and phosphating plants for aircraft engine part manufacturers are typically compact line packages that are easy to move and erect. They are delivered preassembled and tested at our manufacturer’s premises and brought to site ready to be installed – hence minimizing costs arising from disruption to production. Typical number of process tanks is 1-2, which are supplemented by (cold/hot) rinsing, desmut and activator tanks/stations. The plant is delivered with Galvatek’s Candovent ventilation system and Galcont automation process, which makes the plant extremely environmental friendly and also easy and safe to use.
Process of the line
Etching, also known as chemical milling, is the process of using acids, bases or other chemicals to dissolve unwanted materials such as metals, semiconductor materials or glass. This process has been used on a wide variety of metals with depths of metal removal as large as 12mm (0.5 in). Selective attack by the chemical reagent on different areas of the workpiece surfaces is controlled by removable layers of material called masking or by partial immersion in the reagent.
Galvatek plants are always scaled and designed by the needs of the customer and product maximum dimensions in the treatment process. Typical tank sizes delivered for etching, milling and phosphating plants for aircraft engine parts are usually up to 2 meters in length. Regardless, also larger tank sizes are possible.
