Sii’s expert team provides complete industrial installation solutions – mechanical, electrical and pneumatic assembly, control cabinet prefabrication and production suport.
We specialize in mechanical and pneumatic installations, carried out strictly per technical plans and project documentation. Our scope includes equipment positioning, device connection, leveling, and full integration of installations — on-site — across manufacturing plants and industrial facilities. Sii’s team ensures every system is correctly mounted and functionally verified against production requirements — from conveyors and fixtures to peripheral components. We also integrate material handling equipment and heavy machinery to keep lines stable and adaptable. We perform inspection and targeted repairs of existing machinery and equipment to speed up integration and maintain smooth operation with minimal disruption to industrial processes and industrial equipment.
Sii’s experts bring years of experience in executing high-end industrial electrical installations in automotive, intralogistics, and food processing environments. We prepare cable trays, route cables precisely, and execute connections per technical plans – including power distribution checks and grounding systems where required. Our specialists wire electrical systems, connect perimeter devices, and run methodical electrical tests. We also handle cable marking, rack installation, and final device testing – all in line with safety regulations and electrical safety best practices. With us, you get a well-organized, high-performance electrical infrastructure and local electrical distribution points that simplify maintenance and future expansions.
We excel at designing and prefabricating control cabinets – either at your facility or in our fully equipped workshop. Whether you need brand-new cabinet designs or have your own documentation, Sii’s professionals will incorporate advanced testing, wire labeling, electrical wiring, and power supply configuration for precise outcomes, including the installation of electrical equipment such as electrical panels and electrical devices. We perform thorough inspection to verify compliance with electrical plans where applicable. This shortens lead time and supports scalable changes and specialized equipment, reducing the risk of unplanned breakdowns.
For clients looking to upgrade or modernize existing equipment, our engineers conduct a thorough review of current assets and identify potential for improved performance. Through carefully implemented mechanical, electrical, or software optimizations, Sii upgrades older lines into alignment with Industry 4.0 principles. Our enhancements simplify daily tasks, elevate output quality, and can be performed with minimal production interruptions – an essential benefit for sectors like automotive, hi-tech, and industrial engineering.
We are proud of a strong team of industrial engineering experts with direct, hands-on experience across key domains. Their practical know-how, backed by certifications like electrical certifications, working at height, Occupational Health and Safety, ECS, EWF, TISAX AL 3, ensures your project meets the highest quality and security standards. Our specialists are skilled in mechanical and electrical assembly and design, PLC programming, robotics, and automation, using tools like Siemens NX, SolidWorks, AutoCAD, EPlan, ABB, KUKA, and Yaskawa. Whether launching a new line or upgrading an existing one, we reduce rework and enable fast, reliable commissioning.
With Sii’s 1 000 m² assembly facility and 40+ specialized engineers, you save on equipment investments, overhead, and specialized training. Our processes cut extra costs – from material waste to suboptimal workflows – to help you stick to predictable budgets and better ROI. You can channel resources into core competencies rather than having to deal with in-house assembly operations.
We recognize that production demands can shift in the middle of a project. Sii’s flexible approach lets you scale assembly services up or down as needed – so you remain agile when adapting to evolving product lines or sudden market pivots. Whether it’s adjusting throughput or reconfiguring modular stations for new product variants, we keep your line aligned with strategic goals without forcing lengthy transitions or costly downtimes.
