Sandblasting Composites – best grinding alternative

Blast-Tehnik_Fiber-composites

Bond stronger, paint with more shine, deburr all the edges

By shot peening we can improve the mehanical properties of individual aircraft parts. Our team deliver in the field all necessary for quick and qualitatively treatment of the highest standards. We always carry out the measurements after our services and deliver a report on the quality of treatment to our costumers.

How we do the Job?

Blast Tehnik uses robotic, automatic or hand manipulated sandblasting machines, depends on demands, measures and quantities.
Let us do the tests, measurements (roughnes, microscopic structure, endoscop) and qualitiy controls to reach highest standards and optimize the production.

Advantages of the procedure – why sandblasting composites:

  • up to 80% higher bonding strength (save material and provide stronger bonding)
  • smooth surface with low abrasion (100% treated surfaces without breakthrough spots)
  • clean and unique structured surface (enable direct further use without improvements)

Fields of use:

  • automotive parts (construction elements- exp. roof; steering wheels; decorative elements – dashboards, panels,…)
  • aerospace program (wing components, engine cowlings, landing gear doors, propellers,…)
  • wind power industry (blades, construction parts)
  • medical industry (prosthesis components, wheelchairs,…)
  • nautical industry (steering wheels, propellers, vessel bodies,…)
  • motorsport (cocpit, chasis, wheels, seats constructions,…)
