Engineering > Overview

    A reliable and experienced partner, we will support you from the initial idea to series production.

Trust our experience.

In 1997, SII Technologies was founded as a classic engineering office named CADCON. Since then, it has continuously expanded its range of services. We can now offer our clients everything from a single source: We function as a service provider, producer, and systems supplier rolled into one. But development services are at the heart of SII Technologies – our passion is development, and service is our conviction. We develop client-specific solutions of the very highest quality at our 12 locations around the world

Digital Beehive 4.0

The flexible Engineering and IT Support for mid-sized companies

The private cloud solution of the SII Technologies saves costs and allows a fast adaptation to your request of capacities.

During order peaks, there is always the same question: “How can we adapted data handling, project performance and capacities quickly to current requirements?” The answer is Digital Beehive – the ultra-modern private cloud solution from SII Technologies. The virtual Beehive inspires the workflow, opens up pioneering work environments and internal recruiting becomes unnecessary.


Scalable solution with high data security

The Digital Beehive bundles engineering and IT know-how for mid-sized companies. Experts are available by using virtual workstations. For networking the Digital Beehives offers everything from a single source. We supply from hardware and software components for external access up to virtual CAD workstations, installation and support. With the use of the private cloud, everyone works with the same information, without exchanging large amounts of data. Instead of bytes we transmit pixel, so the data sovereignty is save.

Outsourcing. Easy. Do it. With your private cloud

Experience from many areas of application and close cooperation with mechanics allows quick, reliable project execution. From the first draft of the circuit in the form of a circuit diagram to the construction of the control cabinets, we offer our clients the complete range of services, including documentation. We are also the right partner for secondary and primary planning of mid- and high-voltage switchgears for transformer stations. In this area, we support you in implementing your projects in the area of energy distribution.

Analysis and Simulation


Only when the connections between design and calculation are correct can the best possible product idea emerge. For product development or flow simulation, we develop individually tailored solutions for problems of strength, fatigue, and dynamic behaviour for elements made of various materials. Professional execution of linear and non-linear FEM analyses and the skilful application of the corresponding guidelines (DIN, FKM, AD, EC, HSB) form the basis of successful project work.

Robot Simulation


Development times are becoming increasingly short, and the complexity of automated plants is accelerating. In order to keep up with this trend, we perform virtual analyses of function, collision resistance, accessibility, safety, etc. using simulation tools as early as the design phase. The advantages are that the risk that the plant does not exhibit the required functionality when it is built is minimized, and the commissioning time is drastically reduced because problems such as costly modifications are avoided. The programming of individual robots is also first done in simulation tools, so that the programming need only be transferred to the actual robot and run. The cycle times can thus be verified ahead of time, which significantly reduces robot programming time.

Further development of nose and
main landing gear

As an engineering partner of Grob Aircraft AG, the SII Technologies developed the nose and main landing gear of the G120TP for the more stringent requirements of the new models.

The challenge was in the increase of the take-off weight and the improved aircraft performance. In addition, all parts are now milled on not welded together as was previously the case.

The project encompasses engineering – design and stress – of the nose and main landing gear, including certification reports and tool design.
