From engineering to quality control, every process is managed in-house to ensure the highest standards of precision and performance.
Our wire and sinking EDM technologies deliver exceptional accuracy and repeatability for the production of complex and high-precision components. Operating in a temperature-controlled environment, these processes ensure the dimensional stability and quality required for the most demanding tooling applications.
Our high-speed milling department combines advanced CNC machining centres with temperature-controlled production environments to achieve exceptional accuracy and surface quality. High-performance spindles and cutting technologies enable the efficient manufacture of complex components with outstanding precision and reliability.
Our milling department provides versatile CNC machining capabilities for a wide range of tooling and manufacturing requirements. Combining precision, efficiency and flexibility, these technologies support the production of components of varying sizes while maintaining high standards of quality and reliability.
Our turning department combines CNC and conventional machining technologies to produce high-precision components for a wide range of tooling applications. Advanced equipment and specialised expertise ensure accuracy, efficiency and consistent quality across every stage of production.
In order to achieve the precision and the high quality finish required for each detail of a tool, Stema Tech is equipped with a department of grinders for both flat and round surfaces, that encompasses numerous machines of high quality level.
Among these, noteworthy is the large tangential grinding Okamoto ACC-208EX that has a working area of 2.000×800 mm. Its work table is also suitable for the sharpening of molds and dies received for maintenance.
Our assembly department brings together skilled craftsmanship and technical expertise to ensure every tool is assembled, adjusted and optimised to the highest standards. Careful fitting and fine-tuning processes guarantee the precision, efficiency and reliability required for demanding industrial applications.
Our testing and trial capabilities allow us to validate tooling performance before delivery, ensuring reliability and production readiness. By carrying out in-house trials and pre-production testing, we optimise tool efficiency, reduce commissioning times and guarantee consistent results.
Our quality control department plays a key role in ensuring the precision, reliability and consistency of every tool we manufacture. Using advanced metrology systems and comprehensive inspection procedures, dimensional verification is carried out throughout the production process to maintain the highest quality standards and guarantee full compliance with project specifications.
By combining in-process controls with dedicated off-line measurement and testing activities, we are able to identify and eliminate potential deviations at every stage of production. This rigorous approach helps ensure maximum accuracy, repeatability and performance in the final product.
In addition, our reverse engineering capabilities allow us to accurately analyse and reproduce existing components and tooling, providing effective support for maintenance operations, spare parts production and the optimisation of existing solutions.
