Corporate profile

Toolmaking in a class of its own

At SIMON Tooling, we manufacture high quality tools for our own needs of our business divisions BETEK, SITEK and SINTERLUTIONS. The special requirements of these areas with regard to quality and adherence to deadlines are a daily incentive for us to maintain our work at the highest level and to continuously improve it. All tools for the business divisions of the SIMON GROUP are developed, designed and manufactured centrally at SIMON Tooling.

In addition, we also offer our unique manufacturing expertise and our efficient service center to external customers and partners. In doing so, we maintain an open and cooperative relationship – always linked to the goal of developing the optimal solution for each of our customers. This applies to maintenance, as well as to the construction of samples or the production of small series.


Our solutions set standards in user-friendliness and cost-effectiveness. Leading machine manufacturers worldwide appreciate this

The SIMON GROUP employs around 740 people and has its headquarters in Aichhalden near Schramberg. The individual companies have been subsidiaries of the listed INDUS-Holding AG since 1992. All company divisions operate both independently and jointly on the market.

SIMON Analytics is our in-house testing laboratory, where we carry out corrosion tests, climatic tests and coating thickness measurements, and also perform other special tests on request.


As one of the leading manufacturers, SITEK produces carbide-tipped tools, carbide powder and studs for winter tires. SITEK has established itself as a technology partner of the major tire brands, and is involved in the development process of new tire models at well-known manufacturers.

SIMON Sinterlutions uses complex pressing and sintering processes to produce high-quality, sophisticated, ready-to-install components that are used in the automotive, power tools, mechanical engineering and furniture industries.

As an independent company, BETEK is part of the SIMON GROUP, which evolved from the Karl Simon company founded back in 1918. Today, the SIMON GROUP consists of the companies SIMON Sinterlutions, SITEK and BETEK, as well as the profit centers SIMON Tooling and SIMON Analytics.

As a company that operates sustainably, we at SIMON Tooling feel our obligation towards future generations. Therefore, we attach great importance to the preservation of the environment and rely on an active environmental and energy management system. As in all areas of the company, our thoughts and actions are guided by the principle of continuous improvement.

Based on legal and regulatory requirements, the planning and actions of all employees are geared to the responsible use of energy, raw materials and supplies. We are led by the following guidelines: avoid, reduce, recycle and talk about it.

We pay attention to environmentally friendly or environmentally compatible processes and products, as well as controlled energy consumption. We regularly improve all the measures required to achieve this through systematic and structured procedures, energy-efficient technologies and the use of renewable energies.

The basis of our continuously optimized environmental and energy management system are the ISO 14001 respectively ISO 50001. Our goal is the consistent implementation of an environmental and energy policy in accordance with our corporate principles.

Quality & Service

Our claim? Highest quality

We place the highest demands on the quality of our developments and manufacturing – in line with the motto “Only the best is good enough”. This also applies to our customers, to whom we want to offer only high quality products combined with our special know-how and our great experience. We have high-precision machines at our disposal for measuring our tools. In addition, we clearly follow the certified, process-oriented quality, environmental occupational safety and energy management system in accordance with the requirements of ISO 9001, ISO 45001, ISO 14001 and ISO 50001, as well as the automotive-specific requirements of the technical specification IATF 16949. We use the latest CAD/CAM technology to manufacture our products. In doing so, we benefit from the many years of experience and the constantly improving expertise of our design engineers with regard to a wide variety of production processes.

For effective workflows and the optimal control of our manufacturing and value-added processes, we rely on a professional project management system and state-of-the-art systematics in the form of store floor management, the so-called “talking shelves”. To implement our innovative, high-precision tooling solutions, we rely on state-of-the-art machinery. Added to this is the extensive experience and comprehensive know-how of our specialists in a wide range of professional disciplines.

The health of our employees is a matter close to our hearts. Just like compliance with occupational health and safety topics, it is also an important part of our corporate culture. That is why we strive to systematically optimize working conditions – with a constant focus on safety and health. Our basis for this is the Occupational Health and Safety Management System (OH&S Management System) according to ISO 45001. Consistent application of these preventive measures can prevent accidents, reduce absenteeism and improve the general health situation of our team.


In purchasing, we attach great importance to comprehensive sustainability – just as we do in all other areas. Our requirements for current and potential suppliers are designed accordingly.

Seamless quality assurance is the prerequisite for manufacturing the highest quality products. In addition to the careful analysis of all raw materials supplied, we, therefore, also subject our own powder mixtures and granules to close scrutiny. All our semi-finished parts and sintered parts are also constantly tested. These include, for example, measurements for hardness or for determining carbon content or magnetic characteristic values. In terms of carbide grades, we mainly test for density, flexural strength and wear.

All measurements and tests in our workshop laboratory are carried out using state-of-the-art equipment. Our laboratory equipment includes, for example, an ICP spectrometer for elemental analysis, various light microscopes for assessing microstructures, and a scanning electron microscope with up to 10,000 x magnification. Other fixed components include a laboratory attritor for process and product development, a rotary evaporator, and several laboratory furnaces for near-series sintering.
