Duo at the Hanover Messe I
Once again, Dörken MKS-Systeme is represented in two areas at the Hanover fair (4th – 8th system for every component as far as
micro-layer corrosion protection is concerned,” says Dr. Gerhard Reusmann, managing director of Dörken MKS-Systeme. On stand F11 in hall 27 Dörken will be presenting high-performance systems for
the steadily growing wind energy market in the scope of the “Wind - Leading Trade Fair for Wind Generation Technology, Components and Services”. Approved by the major manufacturers worldwide, proven and specified problem solutions such as the system comprising the basecoat Delta® Tone and the topcoat Delta®
- -Seal have been incorporated in wind
turbine construction for over 15 years now, particularly in the area of rotor blade fastenings. Special systems of the Delta-Protekt® series for offshore use are on display in Hanover. In addition to high corrosion protection requirements, this area of application also calls for optimal ease of fastening on the construction site.

a stand in the ‘SurfaceTechnology’ area focusing upon the field of automobile construction, and a stand in the ‘Wind’ area focusing on Dörken’s system solutions for the construction of wind energy plants.
n the ‘SurfaceTechnology’ area, in Hall 6, Dörken will present the new field of electroplating on stand H29, alongside the established zinc flake system of the Delta-Protekt®
systems of the LPO series are set to be developed further, with a focus on high-quality, functional corrosion protection. As a consequence, Dörken MKS-Systeme is appearing at the fair as an all-round provider in the area of corrosion protection. “In future we will be able to offer a Delta-MKS®
series, with a focus on “Connecting elements in automobile construction”.
With the takeover of LP-Oberflächentechnik GmbH of Schalksmühle at the end of September 2010 the area of expertise in this field has been further extended to cover this discipline at Dörken MKS-Systeme. The ecologically-aligned electroplating
Induction heating on HILGELAND formers
Stainless steel fasteners of higher value are used in the commercial and all the industrial sectors. The production of these fasteners creates high demands on manufacturers and suppliers.

he stainless precision parts forming process increases tool wear. They are produced at a low output compared with the production of steel fasteners. By heating the material with means of resistance heating it is possible to achieve a better quality and operational performance. Resistance heating can easily be retrofitted in old machines due to the fact
that the heating section is outside the machine, between the feed rolls and the contact rolls of the heating system. By resistance heating the complete length of the wire is heated. By the time the material is formed there is a high heat loss. HILGELAND Formers are already prepared for induction heating. The induction
coil is placed directly in front of the cutting station. Long cut-off wire can be heated partially, heating only
the wire section required for forming. The loss of temperature is minimal. All radiation of heat can be
absorbed by recuperator for protection of the nearby machine components. Induction heating operates without contact of the wire. No special wire
coating is needed. Immediately after starting the machine, heated wire material is available. There are only two or three cold cut-offs in the cut-off bush that are dropped off. Induction heating allows easy temperature setting and control. Less
