Description
Despite the significant progress that has been achieved in the casting industry and has made it one of the most common methods of producing industrial parts, many challenges are still visible in special and sensitive cases. Among these challenges, we can mention the production of parts with very complex shapes as well as parts containing internal channels. For example, in an effort to cast parts with complex shapes and parts whose geometric limitations limit the manufacturing method in this way, the necessity of computer simulations should be emphasized. Another group of pneumatic/hydraulic equipment has internal channels that cannot be created by machining and are produced by placing muscle or filler in the casting process. The production of these hydraulic/pneumatic blocks with aviation applications requires the use of special alloys due to maintaining low weight and high mechanical properties. Among these alloys, we can mention A356 aluminum or Elektron’s widely used magnesium aviation alloys, which will have a very complex casting due to the presence of rare earth elements. In this equipment, due to the presence of very thin walls between the fluid passageways and the possibility of fluid leakage in case of any defects and discontinuities, the casting must be grade A according to the ASTM E155 standard and therefore free of any defects. be in this standard. Essa after carrying out financial investment and conducting coherent research and development and following cooperation with international reputable companies has succeeded in localizing and transferring part of this technical knowledge and manufacturing capability from foreign technology companies to Essa and its emphasis is always on Carrying out the process in compliance with grade A and removing any possible defects has been in accordance with the relevant standards.
