Since its founding in 2016, Steeltek, a company located in Satu Mare, has been at the forefront of competitive technology, operating with high-performance machinery which earned us a reputation for quality and precision. During these years of consistent hard work among the team at Steeltek, our equipment list and production capacity have grown significantly. We are shipping parts in a range of materials and thicknesses to both local businesses and partners within Europe, ensuring the quickest lead time from quote to delivery. The engineers and technicians in our team are united by a shared passion for technology and innovation. With a young, growing team at our core, we are committed o getting involved in all stages of a project, from the very beginning to the final touches.

SteelWERK GmbH is fully focused on the machining of steel and other metal alloys. Most of our customers work in mechanical and plant engineering.

For them, we usually work on turned parts such as flanges, weld-on rings, collars and wear rings for pipes and elbows, which are used, for example, when pumping solids such as concrete.

Our core competence:

CNC turning of turned lathes
Ø30 - Ø560 mm

CNC turning long parts
up to 2028 mm long

Sawing of
Round material up to Ø530
Square material up to Ø530

It started as a one-man business with a milling center, our team manufactures - consisting of toolmakers and CNC cutters - now in three CNC milling centers precision parts for various industries.

As a team, we prove every day that quality is no coincidence here.

The machining of prototypes, individual parts and small series in steel, stainless steel, aluminum and non-ferrous metals up to hard milling are part of our range of services.

For use comes the latest CAD / CAM technology that takes advantage of all the currently available milling strategies to 5-axis simultaneous milling on our Hermle C 30 U. We manufacture their samples directly according to their 3D data sets or create the 3D models for milling from their drawings.

Of course, we deliver the parts you need and assemblies and fully assembled, including surface treatment and test report.

Certified to ISO 9001:2008

Our Leistungesmerkmale

The company's strategy is focused from the outset on the consistent use of a CAD / CAM system.

All components, of which there is not already one provided by the customer record will be constructed on the basis of the drawing as a 3D volume model. This volume models serve as a basis for creating the milling programs. The possibility of a 3D simulation of the finished milling program guarantees safe production process.

Another advantage is that allows all production-relevant data such as drawings, 3D data and Rüstunterlagen archived in a database easily.

When setting up the tools we build on the latest technology. In addition to a shrinking unit of the latest generation, we also rely on the tool preset to date know-how. Our tools can be measured either by laser directly on the machine or by means of optical measuring device at the tool presetting for length and radius. Thus, a high degree of precision is guaranteed.

To implement this precision milling parts on our modern machines, our employees are in constant contact with tool suppliers to test new processing strategies or tools.

When machining of prototypes, individual parts and small series in aluminum, steel, stainless steel and non-ferrous metals, our well qualified team proves that quality and punctuality are no coincidence.

Using the latest technology and continuous training of staff, in conjunction with years of professional experience, form the basis for the satisfaction of our customers.

Our Service

To be able to also manufacture parts that are not only produce milling technology, it is necessary to work with reliable partners who take the turning areas, erosion or grinding. These are all certified companies from the surrounding area in order to operate as flexibly and quickly.

Of course, we provide them with their components made on request with a variety of surfaces or hardening treatments. Whether burnished, anodized or plated, hardened or plasma nitrided - here we work with certified partners that provide a high quality manufacture.

If you need a measurement protocol or initial sample test report for a component, we have the opportunity to measure their parts on a 3D measuring machine.

New small machine shop mainly working in the milling field, 3 and 4 axis. Parts are programmed with CAM technology and both complex shaped and simple parts can be machined. Being a small company in a very competitive market, the goal is to provide good prices, quality the exceed expectation and fast lead times. Most shop in this range are equipped with low cost machines, so to have an advantage over competitors it was necessary to invest in higher quality technology. The Okuma Genos is a very capable and reliable machine that can eventually step into production and high quantities jobs without being limited in any way.
Communication will always be easy and support for design will be provided if needed. Eventually also collaboration, aimed to formation, with junior employees can be considered.

Mold and Toolmaking - from Productdevelopment together with our customers to Prototype and Production molds

STEFFENINI srl was founded in 1967 as a generic laboratory with the name of OMS Officina Meccanica Steffenini under the guidance of Francesco, the founding father, who is dedicated to the growth and development of the company.

Francesco's son, Paolo, followed the same track drawn by his father.

Thanks to his skills and dedication that he has always shown towards work, he embarks on a new path at the beginning of 2000 with the name of STEFFENINI VALVES by moving his activities to other markets such as petrochemical, energy and mechanical, developing his skills in production of industrial pumps, flanges and valve components by including design and production of own valves.

At the end of 2018, their son Cristian is added to the company and together they decide to focus on what has always been our core business, the subcontracting, dividing the VALVE CONSTRUCTION and THIRD PARTY PROCESSING activities into two departments so the company name becomes STEFFENINI srl.

The continuous efforts, the search for qualified personnel, the alternation of old structures with increasingly advanced machines, the passion that involves all the staff and the natural vocation that drives them to lavish all their energy, taste, pride in Seeing your company thrive, gain credit and inspire customer confidence is the company's mission.

Specialized above all in the machining of valve components, they are skilled and equipped also for particular machining starting from ø 50 up to ø 2000
