The SIR assembly lines in the automotive sector mainly concern the assembly of engine heads, wheel groups, engine distribution groups or turbines. In addition to this SIR has developed solutions for the welding and assembly of car and motorbike frames.
Generally this lines are capable of self-tooling for each different product code.
The robots are assisted by other accessory systems designed and produced by SIR such as Cartesian manipulators, presses, etc.

Functional Integration

We build robots and mechanisms that interact to share information and balance the workload, to assemble any type of product.

Quality and Efficiency

SIR assembly solutions deliver drastic reductions in production times with impressive increases inquality. All with efficiency over 90%.


SIR lines’ automatic retooling opens the way to randomized production and automation which leaves behind the rigidities of the past in progression to the one-piece batch.

Functional Characteristics

  • Randomized production and automatic retooling
  • Production traceability
  • Optical inspection and functional testing of the finished product


Automation in the automotive world has always been the core business of Sir, which throughout its history has designed and built robotic lines and cells capable of covering the entire production chain of typical components for a modern car.
The industry-specific requirements imposed by the automotive sector in terms of quality repeatability, now comparable to those required in the aeronautics industry,
with extremely short cycle times and near 100% efficiency, make automotive the most demanding testing ground for modern robotics.
In this context, Sir has developed comprehensive solutions characterized by a high level of integration.
These solutions range from processing raw cast components and cores to handling them during the loading and unloading of machine tools, from finishing processes after the initial machining to final assembly operations and palletization.

The possibility of having extremely varied know-how, derived from the countless applications installed, allows Sir to make a horizontal transposition of methods and technologies from sector to sector and from one production stage to another, while still maintaining the targets of efficiency flexibility and high quality.
This is also true for the general industry sector, especially for processes related to assembly and welding such as welding and assembly of rollers for earth-moving machines, assembly of non-e-mobility electric motors, assembly of compressors in the field of white goods, assembly of convector heaters, assembly and welding for vertical warehouse drawers, assembly of solid-liquid separators.
In addition, Sir proposes process operations on metals and components made of plastic or carbon fiber, such as helmets or other accessories.

SIR robots operate at the service of the modern foundry industry, improving conditions in the working environment by taking care of intensive, complex operations on heavy and bulky pieces.
SIR represents the undisputed leader in robotic solutions for process applications related to metals (aluminum, cast iron, steel, brass, special alloys).
Deburring and related operations constitute some of the most complicated realizations in the robotic field, especially because of the demanded precision that requires refined mechanical and software solutions, which SIR customizes for each customer.
Thanks to adaptive tool compensation and virtual programming techniques, SIR’s solutions guarantee constant and repeatable finished quality, compensating for variations between the actual piece and the nominal model.

SIR designs and builds complete Electric Drive Unit assembly line, with robotic stations that cover all process phases, from the feeding of individual components to the final testing and pallettization.
SIR is specialized in robotic solutions for the assembly of electric motors of various types: in electric motors with permanent magnets, operations such as encapsulation and magnet bonding are carried out, while, for example, in those with bars, bar insertion is performed using high-precision vision systems.
In addition Sir proposessolutions for assembling electric batteries, gearboxes, induction rotors, and deburring of battery cases.
Manufacturers in the automotive and mobility sectors have also been investing in design and production processes for years that can lead to a reduction in vehicle mass, aiming for greater autonomy and to offset the significant weight imposed by the batteries.
The frame is one of the primary candidates involved in this weight reduction. The introduction of aluminum die-casting for entire semi-frame of considerable size is indeed the new milestone in construction technology. Plasma cutting with torches manipulated by robots has proven to be the most cost-effective and efficient alternative for the removal of excess material and casting channels in this case.
