Surface Treatment  Manufacturers, Traders, Suppliers

We carry out surface hardening processes (hardening depths 0.1mm up to max. 2mm) on finished (e. g. ground) workpieces with Nd:YAG, fibre and diode lasers with almost no deformations. We are using different NC systems with 3 to 6 axes. Through the use of a 6-axis robot, we are able to manufacture large quantities of small components effectively in series. Here you can find further information on our job order production offers.A high efficiency and process security are ensured with the help of special hardening optics, and optimum control and monitoring of the hardening process is ensured by the use of pyrometers.We carry out metallographic cross-section polishing and hardness measurements for you.

Hardness depths:

• 0.1 mm up to max. 2 mm

Hardness trace width:

• 0.1 mm up to some 10 millimetres

To improve the characteristics of our technical springs, we are offering several surface treatments as desired by the customer.
Those treatments have differnt purposes: a functional purpose for corrosion prevention or noise reduction, a decorative purpose e.g. to distinguish colours or to improve reflectivity, or a combination of both purposes to improve electric conductivity.

Surface treatment - Quality. Precision. Versatility.
Surface treatment is a crucial step in production that ensures the durability and aesthetics of our products. In our company, we attach great importance to quality and versatility in surface treatment in order to meet the requirements of our customers.

• Hardening:One of the most important techniques in surface treatment is hardening. We offer various hardening processes, including conventional hardening, case hardening and induction hardening. In conventional hardening, the workpiece is heated to a certain temperature and then cooled quickly to achieve a high level of hardness. Case hardening enables targeted hardening of specific areas of the workpiece, while induction hardening enables fast and precise hardening treatment through the use of high-frequency current.
• Painting:To give our products an attractive and protective finish, we also offer painting services. Our experienced team uses high-quality lacquers and paints to ensure an even and long-lasting coating. We adapt to the individual requirements of our customers and offer a wide range of colors and surface effects.
• Labeling:Labeling products is an important aspect of surface treatment. We offer various marking techniques, including engraving, laser marking and screen printing. Our precise marking methods enable us to apply permanent and legible markings to the surfaces of our products.
• Anodizing:Anodizing is a process for creating an oxidic protective layer on metal surfaces. It not only provides improved corrosion protection, but also gives the products an attractive surface. We offer various anodizing processes to meet the specific requirements of our customers.
• Coating:Our company also offers the coating of surfaces. Coating involves applying a protective layer to the surface of a workpiece to protect it from wear, chemical influences and other harmful environmental conditions. We use high-quality coating materials and offer various coating options to meet the individual needs of our customers.

In our company, surface treatment stands for quality, precision and versatility. Our experienced specialists and modern facilities ensure that your products meet the highest standards and fulfill the desired aesthetic and functional requirements. Your Windschiegl Maschinenbau GmbH.

Alpha Calcit Füllstoffgesellschaft mbH & Co. KG is one of the leading suppliers of white fillers to numerous industries in Europe, USA, Africa and Asia. The company, which is rich in tradition, was founded in 1919 and has since been run as a purely family-owned enterprise now in its 3rd generation.
The entire value-added chain, from raw material deposits own mining, processing and production facilities to sales and distribution
is vertically integrated in the Alpha Calcit - Group. Own production companies of the Alpha Calcit - Group are located where excellent raw materials are available, which guarantee the production of best mineral fillers in the long run and future-proof.
A total of more than 115 employees ensure presence in the market. Production sites are located in Germany, Austria, Italy and Turkey.
Our product portfolio is based on bright white fillers. As mineralogical-chemical basis, in addition to
- natural calcium carbonates in crystalline and microcrystalline form
- natural layered silicates such as talc
- synthetically hydroxides (ATH)
- precipitated carbonates (PCC)
- other silicates and
- titanium dioxides
are used. Some product classes are supplied both non-treated and surface as well as surface modified.

SUR-SULF is a surface treatment of metals by thermo-chemical means. ( No coating ) It is carried out at a temperature of 560°C. What does the SUR-SULF treatment do?A very high surface hardness of the treated workpieces (without embrittlement), which, depending on the material, can reach over 1000 HV 0.1;very good running-in, sliding and emergency running properties due to the presence of iron sulphides in the surface of the workpieces
a considerable increase in corrosion resistance
an increase in fatigue strength due to a strong nitrogen diffusion zone
Which materials can be treated?
Unalloyed steels
Alloyed steels
High speed steels
Stainless steels
Cast iron
