Surface treatment
Technologies we use for surface treatment
At Blast Tehnik, we use six technologies to treat surfaces in the pharmaceutical, automotive, food, chemical, aerospace and electrical industries. We meet the highest requirements for surface treatment of batch and small batch pieces for you. With us – at the location of the company, or in the field.

Paint removal – dry sandblasting :
- removes paint without damaging the surface of the material due to the hardness of the blasting medium 2.5 – 3.5 MOHS
- on parts that have been micro-forged, remove the paint without reducing the effect of micro-forging
- environmentally friendly method – recycled plastic
- without the use of chemicals to dissolve the paint
Dry or wet blasting with glass beads :
- sandblasting without deformations on workpieces
- it also deeply cleans uneven surfaces and holes
- eliminates the need for manual polishing
Advantages :
Non-abrasive sandblasting :
- removes paint without damaging the surface of the material due to the hardness of the blasting medium 2.5 – 3.5 MOHS
- on parts that have been shot peened , remove the paint without reducing or nullified the effect of micro forging
- environmentally friendly method – use of recycled plastic
- without the use of chemicals to dissolve the paint
Dry or wet blasting :
- sandblasting without deformations on workpieces
- it also deeply cleans uneven surfaces and holes
- eliminates the need for polishing
- smoothes the surface and thus reduces the application of impurities
