Areas of Expertise and Advanced Services
State-of-the-Art Tooling: From Prototype to Mass Production
We specialize in the manufacturing, maintenance, and repair of molds, delivering tailored solutions for a wide range of industrial applications. With a team of experienced engineers and technicians, we design and develop injection molds, stamping tools, and complex forms using advanced CAD/CAM design and digital injection simulation technologies.
Our tooling services include:
- Design and manufacturing of custom molds tailored to client requirements.
- Mold repair and preventive maintenance to extend equipment lifespan.
- Optimization of existing molds to improve production efficiency.
- Manufacturing of tooling (jigs, fixtures, and gauges) for quality control and part compliance.
Serial Production and Custom Parts – Micron-Level Precision
Using advanced CNC machining technologies, we are capable of producing both unique parts and small to large production series, meeting strict tolerances and demanding technical requirements.
Our machining capabilities include:
- CNC turning and milling – precise processing of metal and polymer components.
- Grinding and lapping – high-precision finishing for critical surfaces.
- Wire EDM and spark EDM – advanced technology for complex contours and fine details.
- Manufacturing of rotational parts used in high-precision mechanisms.
Additionally, we offer extensive prototyping capabilities, enabling design testing and validation before mass production—essential for industries such as aerospace, automotive, and medical, where every detail matters.
Plastic Injection Molding – Efficient Production and High Reliability
We operate a modern plastic injection department where we manufacture components for a wide range of industrial applications. Using high-precision molds developed in-house, we ensure perfect reproduction of every geometric detail.
- Design and development of plastic components based on client specifications.
- Simulation-assisted injection molding to optimize processes and reduce defects.
- Strict metrological control for every production batch.
