Aerospace Chemical Milling

The aerospace chemical milling and photo etching industry comprises companies producing aircraft, space vehicles, aircraft engines, propulsion units, and related parts. Aircraft overhaul, rebuilding, and conversion also are included. At Shimifrez we believe that building prototypes of newly designed products, run tests and experiments, and perform a variety of other technical tasks before mass production is crucial. Chemical Milling removes surface-related materials of the part before the etching process takes place. The process starts with a CAD file that is used to create a  photo-tool. Top and bottom patterns of the metal that is supposed to be milled are designed , after which the metal will undergo preparing and degreasing. This preparation is necessary for application of photoresist, which is used to transfer the desired pattern by UV light and developers.

Some of the manufactured parts include:

Fast Turn around Prototypes

  • Delivery of your conctacts and connector in less than 5 days
  • Reduce the risk of hard tooling
  • Burr and Stress free components
  • Design changes and modifications can be done within hours.
  • Fast lead time for you to reduce your time to market
