To our services

Metal refinement

With our know-how in anodising, colouring techniques, and electropolishing, we can master any challenge. Our state-of-the-art facility in Unterentfelden, Switzerland guarantees fast and professional execution of your projects.

By using the latest technologies, specialised processes, and control systems, we guarantee environmental protection thanks to the reduced use of chemicals as well as recycling. 

Our facilities can accommodate parts from 6000 to 7000 mm in length, which enables us to treat even very large workpieces.

Derouging

Derouging is the process of removing rouge, a corrosion product on stainless-steel surfaces.

Thumbnail
Passivation

Passivation forms a protective layer on the surface of the material that is rich in chromium oxide.

Special cleaning processes

We clean with pH-neutral chemicals that do not attack stainless steel and can be disposed of in an environmentally friendly manner.

We utilise hydroelectric power

The energy we use is 100% Swiss hydropower. This electricity is generated by Swiss power plants that supply the power grid. By purchasing this electricity instead of conventionally generated power, we improve our CO2 profile.

Documentation

We carry out all our technical operations in an SOP-defined, multi-stage, controlled process. We precisely record every measure and every step so that nothing is left to chance. The documentation starts with the initial analysis of the system condition and records all work steps and the use of all chemicals right through to the final inspection.

Transparency and validation

We give you complete transparency – from safe-source, precisely defined chemicals to each individual process parameter like concentration, temperature, and time. All data and procedures are precisely defined, documented, and recorded for you in a manual that supplements your qualification documents once the work has been completed. Our documentation ensures reliable traceability and the compatibility of our work – so that you always have an overview of the condition of your system and can plan maintenance and cleaning accordingly.

We provide you with the following documentation as a standard part of our services:

  • System condition before treatment (visual assessment, rouge layer thickness, surface roughness, etc.)
  • Details of the cleaning processes (chemicals, metal content, concentration, process parameters (target/actual), residue measurement, etc.)

System condition after treatment (visual assessment, cleanliness, residue measurement, surface roughness, passive condition, etc.)

GMP protocols and certificates

We guarantee the safety of your system through comprehensive GMP documentation of all cleaning, derouging, and passivation processes. You receive detailed GMP protocols from us, as evidence that the work has been carried out in a manner that can be validated and is transparent.

Our pharma-compliant GMP protocols record every step of the process in detail, monitor compliance with the defined acceptance criteria, and record any deviations. If deviations occur, they are recorded & clarified and appropriate measures taken if necessary. 

We provide you with the following protocols and certificates: 

  • Analysis certificate of the chemicals regarding purity and originality
  • Protocols of the condition of the system before treatment
  • Execution protocols (verification of process steps, testing according to acceptance criteria, documentation of deviations)

With these GMP documents in hand, you can be sure that the maintenance and care of your system is carried out to the highest standards.
