Peening and de-painting (PMS) are common processes. All of which require equipment capable of precise control and are used in the aerospace industry.
Aero engines operate at the absolute limits of engineering and require coatings to operate at the extremes of cold and heat. Sermetal™ and Indestructible Paints™ are the industry standard coatings. These require an even key to enable the coatings to successfully bond to the substrate. Hodge Clemco has a range of cabinets offering efficient grit cleaning solutions. They ensure that the media propelled from the nozzle is of consistent size and shape. Our cabinets are heavy duty in nature. They are capable of withstanding the high wear rates associated with Aluminium Oxide grit blasting.
Hodge Clemco has a proven track record of supplying innovative and cost effective solutions to the aerospace industry.
PMS systems are extensively used by the military and commercial aviation industry. They are used to remove coatings and colour schemes from aircraft prior to repainting. The use of appropriate media to selectively remove the paint, without damage to the thin aircraft skins is the most important decision in a PMS facility. Plastic media is almost exclusively used for this application, replacing the earlier Wheat Starch media systems. Dense particle and magnetic separators are fitted in our PMS facilities in addition to vibratory media grading systems. Our PMS facilities have been extensively used by the RAF and the process is approved.
Peening is an operation which induces compressive stresses on critical parts, removing induced tensile stresses caused from cold working operations. It can significantly increase the fatigue life of critical parts as well as work harden the surface of a material. As with grit blasting, the use of efficient shot classification and cleaning systems ensures that the media size and shape is constant, offering repeatable results. Military specification shot and glass bead are commonly used in our peening range of equipment.
