SITEK - Specialized in Studs,
Tungsten Carbide Tools and - Recycling

Corporate profile

Our name stands for safety

And that in the truest sense of the word: SI-TEK is the German abbreviation for “safety technology” and is deliberately made a top priority at our company.
At SITEK, we offer you the complete vertical range of manufacture: from development to our own carbide and sleeve production to the finished spike. Thus, we cover the entire value chain in carbide production with our products and offer you exactly the quality you desire.

SITEK produces carbide powder and manufactures carbide-tipped tools and studs for winter tires. We are one of the leading manufacturers of studs for car and truck tires. As a technology partner to the world’s major tire manufacturers, we are involved in the development of new tires from the very beginning.

Thanks to our own carbide production, we can mix the raw materials completely individually according to the respective desired carbide quality. This allows all material properties to be precisely matched to the future application. SITEK, for example, has developed special types of studs, which are used in winter tires, on the one hand, and are also suitable for bicycle tires and hoof nails, on the other. Carbide tools from SITEK are used on milling machines, for example, to remove pavements from roadways or to roughen and clean floors. These tools are highly resistant to wear and are designed for economical use.

Quality Management

Thanks to our large vertical range of manufacture, we are able to produce the best possible quality. In our in-house materials laboratories, we permanently monitor the quality of raw materials and manufactured products throughout the process. The process of carbide production is subject to end-to-end quality control: from raw material receipt through spray drying and pressing to sintering.

In our laboratory, we carry out all analytical procedures for the quality assurance of carbide. In addition, there are special procedures on various test rigs for quality control of finished products – for example, wear control of the various carbide grades. All manufacturing steps are thought through to the smallest detail; they are seamlessly monitored, controlled and constantly improved. Experience gained from practical tests is also regularly incorporated into the improvement process.

The high standard of our quality and environmental management is certified according to ISO 9001, ISO 14001, ISO 45001 and ISO 50001.


Recyclable, cost-efficient, environmentally friendly

Recyclable, cost-efficient, environmentally friendly We are committed to active climate protection and see SITEK as playing a strong pioneering role: We already use up to 85% recycled carbide raw materials. Recycling eliminates the very energy- and CO2-intensive primary processes for extracting and preparing raw materials. A large proportion of our recycling raw materials comes from our own patented carbide recycling process.

In addition, we have introduced a SIMON GROUP buy-back system for carbide scrap from surrounding European countries, in order to further reduce CO2 emissions and transport routes for scrap. Our recycling process runs without chemical additives and subsequently enables complete granulation into new carbide powder. We currently recycle up to 80 tons of carbide per year.
