Surfaces with fingerprint

Every successful manufacturer knows the problem - plagiarism and product counterfeiting.

The resulting economic damage for manufacturers and users is considerable and manifold. There are many reasons why it is necessary to apply a marking or a unique fingerprint to a component in order to prevent this damage or to make a plagiarism recognizable. Whether it is protection against plagiarism and brand protection, proof of origin or marking for application, unique marking of metallic components often creates significant added value.

Technical solutions for such markings exist in many forms, but often the durability of this marking in the operating environment of the component is of particular importance. Most technical anti-counterfeiting solutions cannot withstand these often very harsh conditions. The incorporation of an appropriate marking in or on a corresponding functional coating represents an efficient way of obtaining this additional benefit. Thus, the component is not only protected against corrosion or wear, but also carries a permanent identifying or tamper-proof marking.

Depending on the complexity of the coating system and the requirements, identification is provided optically, using simple analytical methods or even electronically with portable or permanently installed devices.

CERODEM® - a look at our thin film portfolio

In addition to electroplated and chemical coatings, we also offer a selection of physically deposited coatings.

These are thin coatings, usually 2-4µm layer thickness, produced by PVD / PACVD process (Physical Vapor Deposition / Plasma Assisted Chemical Vapor Deposition) under high vacuum, at temperatures below 200°C.

These coatings are characterized by excellent wear resistance and high hardness (approx. 1500-2500 HV). Typical representatives here are CrN (chromium nitride), CrC (chromium carbide), WCH and DLC (diamond like carbon) coatings. The latter can also be specially modified by doping with additional elements.

By selecting the appropriate coating type and process parameters, it is possible to influence the protection against adhesive and abrasive wear, hardness, maximum operating temperature or the demolding behavior of plastics ("adhesion or non-adhesion").

In targeted combination with galvanic or chemical coating systems, our so-called "hybrid coatings", even higher load-bearing capacities on softer base materials and/or better corrosion protection can be achieved while retaining all the other advantages of this coating technology as a topcoat.

As usual, it is also worth taking a look at our Coating Guide "Valentino". In addition to all specifications, applications and areas of use, you will find the contact details of the person responsible for these applications - we will be happy to answer your questions.

Energy turnaround with tin coatings on track

Future developments in the field of energy system transformation, such as energy storage, fuel cells and batteries, depend on intelligent and stable power supply systems. For this purpose, electrical contacts must be soldered together and intact circuits must be ensured.

Tin layers have very good electrical conductivity and solderability. In combination with their high ductility and self-lubricating properties, they are therefore ideally suited for current-carrying components and plug connections. In addition to busbars and bus bars, the coatings have established themselves in numerous other applications in the electrical and electronics industry. In this context we can of course also offer the combination with an electroless nickel layer as a diffusion barrier. This prevents the whisker formation of tin layers on busbars, which often leads to short circuits.

In addition, tin layers are also used in the food industry - e.g. in cans - due to their food compatibility and high chemical resistance.

The components can be coated in both barrel and rack processes. We are able to refine the common industrial metals and especially copper or aluminium alloys fully automatically.

De Martin - Silver coatings in technical and medical applications

Silver coatings have been proven for decades in the technical - functional area. Due to the current corona pandemic, the antimicrobial effect of silver is becoming increasingly important.

Silver coatings have some properties that make them particularly interesting for technical applications. Silver is the best electrical conductor of all metals and has a low contact resistance. Therefore, silver coatings are used in many different applications in electrical engineering. But silver also has interesting tribological properties. Silver is ductile, can take heavy loads, does not weld and does not tend to corrode. These properties are used to prevent seizure of components such as screws, nuts and threaded inserts that are in contact with each other, exposed to vibrations and high temperatures. Silver coatings are a suitable alternative to greases and dry lubricants for the high temperature range.

Coatings can also make a valuable contribution in medical technology:
The antimicrobial effect of silver has been known for a long time and is based on the fact that silver ions form an irreversible bond with all biogenously present oxygen, nitrogen and sulfur compounds. This disrupts the biological system and reduces the formation of biofilms. Silver coatings are therefore a suitable method to effectively reduce the bacterial count on surfaces. This property is used, for example, in the coating of components for respirators in intensive care medicine.

Occupational safety - Together with local associations against accident risks

Occupational safety, health protection and accident prevention are important components of our daily life. Especially when dealing with chemicals they are often even vital.

Together with the Samaritan Association and the Wängi fire department as well as the trained first-aiders of the De Martin AG we have carried out an association exercise for the quick and correct treatment of possible consequences of accidents.

Each participant...

- Provides correct first aid in case of an eye injury
- Knows the three degrees of severity of burns
- Cares for a patient with a cut injury professionally
- Performs first aid correctly in case of burns

At four stations, all of the above-mentioned injury patterns were dealt with using practical examples and the corresponding procedures were practiced.
It was a successful event for all participants, where not only in theory but also in practice important first aid topics could be practiced on site.
We would like to thank the Samaritan Association and the Wängi Fire Department for a great joint event, which we will certainly repeat in the near future.

Hard layer for soft aluminium

For good a year now, we have been offering you our DEMACOAT® process at our German location in Neustadt. For this purpose, we have the possibility to coat your components in a modern, fully automatic and process-controlled plant.

The DEMACOAT® process is an electrolytic treatment of aluminium materials which results in the formation of a hard abrasion and corrosion resistant layer. In the cooled electrolyte and with the aid of electric current, layer thicknesses of up to 200 µm can be produced on aluminium alloys, depending on the alloy. 

To improve the tribological properties, the hard anodised layer can be impregnated with PTFE or, to achieve visually attractive results, it can also be coloured black. Furthermore, we can also pre-treat your components in different ways or even partially coat them.

Challenge us and send us your inquiry.

Learning for life - "Shop Floor Management at De Martin AG"

Well-trained and experienced employees are an essential prerequisite for the continuous improvement of a company. De Martin AG places particular emphasis on the training and further education of our employees.

Currently, all department heads from logistics, production and technical maintenance are completing a training course lasting several days in cooperation with SWISSMEM and other partners.

In addition to strategic and business management topics, the focus is specifically on shop floor management (SFM). SFM is a component of "Lean Manufacturing", from the well-known Toyota Production System (TPS).

Terms like "Go And See" (go on site and take a look) have shaped this type of management.

One of the best translations for shop floor management is probably "leading at the place where value is created".

Important key figures are visualized in the different areas in order to identify deviations, solve problems sustainably and optimize the use of resources.
