Oerlikon Balzers proudly welcomes DMX as part of its group as of 1 January 2017. Oerlikon Balzers is one of the world’s leading suppliers of surface technologies that significantly improve the performance and durability of precision components as well as tools for the metal and plastics processing industries.
The purchase will enable DMX to provide its customers with even more know-how and a comprehensive set of offers for surface treatments. Our global footprint thus further puts us in the position to be close to our customers wherever they need us. The transaction has no operational impact on the ongoing business. Business and cooperation of DMX will continue as usual.
DMX will continue to focus on coating solutions for punches, dies, cutting tools, injection molds and moving elements, dental implants and medical devices, etc.
Our PVD coatings increase the performance of tools in terms of resistance to wear, abrasion, corrosion, oxidation at high temperatures, sticking, etc.
Le conseil technique

Technical Support and Tool Processing

Our team of highly qualified engineers is trained to analyze your applications and recommend the PVD coatings best suited to your needs and requirements.
Every detail is carefully examined in order to choose the optimal method of preparation for coating.
From the outset, every precaution is taken to detect possible cracks or chipping, and retain the integrity of the tools entrusted to us.

Preparation

Pre-coating Preparation of Tools

After collecting all pertinent data, job travelers are produced, indicating a specific method of pre-coating preparation:

  • manual micro blasting
  • automatic micro blasting
  • manual cleaning
  • automatic cleaning
  • steam cleaning
  • stripping / decoating
  • additional treatments

Job travelers outline specific production processes for each order. To ensure quality these job travelers remain with the order through to completion.

PVD Arc Coating Technology

Tools are placed in a vacuum chamber (10-5 mbar) and heated to a prescribed temperature of 300-500°C.
Once the chamber is evacuated and the desired temperature is reached, the metal constituent of the coating is evaporated from the targets with electric arcs to form highly ionized plasma. The elements of plasma are then combined with different gases and condensed on the substrates.
By using different types of targets (single or alloyed material) coatings can be developed and realized as monolayer, nanolayer, multilayer, gradient and as combinations of these structures. DMX produces usual coatings as well as highly sophisticated coatings (TiN, TiCN, TiAlN, AlTiN, AlCrN, TiAlCN, TiAlCrN, ZrN, CrN, AlCriSiN, etc).

Optimisation

Optimization of PVD Technology

The quality and performance of our coatings are directly related to the finely calibrated capacity of our coating units. We can offer dedicated loads which guarantee a very high degree of homogeneity, a precise control of thicknesses and consistency batch to batch.
Dedicated loads are necessary because each tool is comprised of varying parameters and requires different treatments (for example cutting tools and molds require different treatments, stainless steel substrates and carbide substrates require different recipes).

Post operation

Treatment of Tools after Coating

To optimize performance from coating applications DMX offers a vast array of post-coating treatments (for example to improve sliding properties), and has the technical capacity to tailor treatments to your specifications.

Qualité

Quality Control, Traceability, Certification

The size of our coating chambers and the dedicated loads enable us to deposit coatings to within one micron specificity. Conforming to the ISO 9001 version 2008 certification, each load is controlled to guarantee the thickness of the coating (test pieces are checked with X-ray equipments) and the perfect adhesion of the coating.
We can of course deliver quality control reports to comply with customer specifications.

Expedition

Packaging and Shipping

Prior to packaging, all orders are subject to thorough examination by our quality control team. Great care is taken to repackage tools in their original form or in packaging specifically designed by DMX to protect and safe-guard tools during transport.

Quality
is at the heart of DMX

At DMX, we have defined and implemented processes that guarantee our services meet the highest levels of quality and efficiency.

Production procedures, overseen by our Quality Control Engineer, guarantee a very high quality product. The technicians validate all steps of production instructions by signing the job travelers which receive final approval from the Quality Manager before the tools are released.

DMX is certified ISO 9001-2008 and ISO 13485-2003 (Medical Applications) by the Swiss Association for quality Systems and Management (SQS).
