About H N Oberflächentechnik
H N Oberflächentechnik GmbH was founded in 2010 by Herbert Neukom in Switzerland and specialises in surface treatment. The company sells mass finishing systems, drag finishing systems, blasting systems, cryogenic blasting systems, electropolishing systems and inspection systems for optical quality inspection, including the appropriate process consumables. The company also offers contract manufacturing: mass finishing, drag finishing, blasting, electropolishing, stream finish or linear force finishing, as well as cryogenic deburring for plastics and elastomers. The offering also includes free sample tests, consulting, a spare parts warehouse for repair and maintenance, and used systems. Since 2021, management has been in the hands of Fabian and Cedric Neukom. Customers include the plastics and rubber industry as well as medical and dental technology.

Processes & Systems
Plastics
Cryogenic contract deburring for all plastics, removing burrs without mechanical stress.
Elastomers/Rubber
Cryogenic deburring of elastomers and rubber, since conventional deburring reaches its limits here.
Mass Finishing
Gentle deburring, edge rounding and polishing of bulk goods in centrifugal, vibratory bowl, barrel and through-feed systems.
Drag Finishing
Contact-free mass finishing of highly sensitive workpieces with short processing times.
Blasting
Blasting and cryogenic blasting systems for surface treatment including process consumables.
Electropolishing
Reliable, precise electrolytic polishing for high surface quality.
Stream Finish / Linear Force Finishing
Defined treatment of individual surfaces; the SF 1/30 was developed specifically for dental drills.
Inspection Systems
Automated optical quality inspection that eliminates the human error factor.
