We stamp and stack laminations for the manufacturing of electrical motors and transformers. Whether small series or major orders: you can rely on us. Tell us what you need, and we’ll offer you the most economical solution. At the right time and with the high quality you require.
A MEMBER OF
Stanzwerk AG is a thriving, international company with ca. 330 employees creating high-quality products and services for the manufacture of electrical motors and transformers. Over 80% of its products are exported.
Stator and rotor laminations are stamped from magnetic steel strips and then joined together into ready-to-instal stator and rotor stacks via in-die stacking, welding, baking, riveting and clamping processes. In subsequent steps, the rotors are cast in aluminium and the rotor shaft is inserted.
The company is ISO 9001:2015, ISO 14001:2015 and IATF 16949:2016 certified. Stanzwerk AG has been part of the SITEM Group since 2017 and was in independent family ownership from its foundation in 1961 until 2017.
Half a century of experience has made us an internationally recognised competence centre for the stamping and stacking of laminations for the manufacture of motors and transformers. We understand what you’re talking about, ask questions, and work with you hand in hand. We always deliver reliable quality at reasonable prices. All from the heart of Switzerland.
We pay special attention to frictionless processes. Everyone involved in the creation of your product works closely together. Important information and requirements are noted and passed on at every step, thus guaranteeing the best possible result.
Every day we learn something new. Every order expands our knowledge level, which is already substantial after so many decades. We can also rely on employees who have been with us for years. Our experience thus remains inhouse, experience that also benefits you in the long run.
From the first customer contact to production to delivery: only highly qualified experts handle your job. Everyone profits from vocational training, higher education or selective further education: our employees, the company — and especially you, as customer. You can count on your order being carried out by experienced, dedicated professionals.
Customer satisfaction is the best indicator of quality. And we have many long-lasting partnerships to prove it. We also maintain partnerships with our suppliers. As a subcontractor, we are often closely integrated into our partners’ processes. In addition, all processes in our company are standardised to ensure consistently high quality. This point is underlined by our many years of ISO 9001:2015, 14001:2015 und ISO/TS 16949:2016 certification.
We reach our goals with genuine win-win partnership, reliability and dedication as well as a continuous improvement process, from development and design to conception and final quality control.
We guarantee maximum customer benefits with our long-term aims of profitability, independence and social responsibility.
In our Design Department, tools are developed on eight state-of-the-art CAD workstations in close cooperation with the customer. We examine the feasibility of your parts and optimise the groundwork. Even in this early phase, we take subsequent economical production into account. While we may use laser technology to manufacture the first individual pieces, we already use specific pilot-series tools for fabricating prototypes. The final tools are then produced from carbide steel with the highest degree of precision. Continuous quality control and precise measurements ensure the finest end product.
In our own Tool Manufacturing Department, where we continuously train apprentices, our expertise is maintained and passed on to the next generation. The highest degree of precision in the finished parts is based on two components: state-of-the-art tools and reliable procedures. With the continuous improvement process (CIP) – from design of the strip layout through intensive design reviews to the ultimate tool manufacturing – we ensure the quality of the finished product as well as the efficiency of the process. You can thus rest assured that the results meet the highest standards.
Our tool maintenance is a guarantee for the optimum production and flawless functioning of the tools. We devote the same level of care to maintaining our stamping tools as we do developing them, because only regular inspection and expert maintenance of precision tools guarantees best results, even after millions of parts.
