For years, the Sitech brand stands for expert design and manufacture of
car seating. For our customers, this expertise and competence means top-
quality products and on-time delivery.
We are systematically expanding our expertise: in the future, we will as-
sume even more responsibilities in the design of innovative seating technol-
ogies, increase our overall unit numbers and manufacture more component
These objectives call on everyone’s full commitment and collaboration.
Though our work is carried out in several different plants around the world,
we share a common goal: safeguarding and expanding Sitech operations.
Our global presence as a maker of innovative, high-end automotive seating
is the best way towards that goal.
towards global markets
Sitech customers are entitled to products of the highest qual-
ity. The quality of our delivery service is no less important. We
make every effort to meet these demands, and ensure that all
our customers are completely satisfied.
At Sitech, we are driven by the need for constant improvement. Together we
design and manufacture innovative products that afford superior, safer seat-
ing. We are also permanently striving to improve operational processes. By
producing robust, durable, high-quality goods at an impressively reasona-
ble price, our work has constant value.
Our best efforts produce
the best products
As a team and at every work station:
we’re only satisfied once we’ve found
the best solution
We are constantly aware that assuming and carrying out personal responsi-
bility is the essential requirement for high productivity. This accountability
is demonstrated day in and day out – by each of us in his respective roles,
and together as a team.
Sitech operations span the globeSeat manufacture is a demanding job: we
welcome this challenge everyday
Strategically positioning Sitech for the future requires design-
ing specific products for specific markets as much as it requires
developing suitable manufacturing concepts for those prod-
ucts. The latter is the main task of Product Management, along
with the equally important responsibility of providing support
to current seating customers.
Along with a great deal of engineering and manufacturing know-how, a host
of administrative processes undertaken by Product Management are re-
quired to produce car seats in a timely and cost-effective manner. These in-
clude constant coordination with customers, processing their invitations to
bid, preparing bid offers, or re-calculating offers as a result, for example,
of changes to production batches due to product upgrades.
Meanwhile, keeping engineering design and innovation in mind, Pro-
duct Management must constantly remain a step ahead: Where are the
growth markets of the future? How can we benefit from that growth? And

Essential to Product Management: direct

Ideal seating begins in the mind – and on the drawing boards and
computers of our developers. The main development team in Wolfs-
burg (Germany), together with their colleagues at Sitech operations
in Polkowice (Poland) and Shanghai (China) either transform our
own ideas for better car seats into proprietary designs, or develop
finished car seats according to a customer’s design model.
From the preliminary development, design and seat cover de-
velopment phases to prototype construction, comprehen-
sive testing and finally to production supervision, the Tech-

operations in Wolfsburg, Polkowice and Shanghai the Technical Develop-
ment ensures that production requirements are introduced into the devel-
opment of new products at an early stage. Product management performed
by Technical Development constantly ensures that the development teams
cover all process areas and remain precisely within specified time and cost
In the future, Technical Development will expand its competence includ-
ing seat covers, headrests, seat structures, metal frames and seat adjust-
ment systems. It will also continue to advance our global orientation with an
enlarged scope of innovative products fit to market and customer needs –
thereby creating a solid basis for our worldwide operations.
And, naturally, in the right quantity and quality. What may seem
like a standard logistics phrase is in practice a highly complex
matter. For instance, exactly those parts that are required on
the production floor at any given moment must always be sup-
plied on time from approximately 4,800 locations.
The challenge for Logistics goes much further. Before reaching the assem-
bly line, the components must be procured. Placing orders for the produc-
tion of a car seat involves arranging the supply of all required components
and parts – from pilot production to serial production – and coordinating
their demand-based delivery with an array of suppliers.
The department also manages the complete planning of logistics streams,
including producibility planning, warehousing facilities and capacities, con-
tainer management and much more. Moreover, Logistics is responsible for
the entire physical handling of materials, from the smallest screw to heavy
seat sets. At Sitech production locations, car seats are supplied directly to

The Engineering/Industrial Engineering (E/IE) department’s
main task is the realisation of production facilities. Manufac-
turing concepts are thereby developed and industrially imple-
mented, while meeting customer requirements and utilising
suitable resources in keeping with innovative production tech-
niques. The E/IE team also carries out ongoing optimisation
trials, and is actively committed to providing an ergonomic and
safe work environment.
Finding the best combination of
automated production and human
labour is a key task of technical planning
Economically and humanly
suitable manufacturing processes
Our manufacturing process always employs the most efficient technologies
and incorporates the latest developments in workflow and process orga-
nisation, in order to ensure the best environment for competitive produc-
tion at the highest level of quality. Following the start of production (SOP),
the supervision of series production team carries out the work of optimising
processes and tasking.
Supervising the car seat’s entire value chain is the overall responsibili-
ty of the E/IE department – from the seat’s metal framework to its full as-
sembly. This responsibility extends across Sitech’s worldwide operations.
E/IE also gathers key productivity figures, and determines measures, to-
gether with respective employees, to optimise procedures and eliminate all
forms of waste.

Careful technical planning is the basis for

In order to consistently achieve the highest level of product
quality, every step of the production process must be meticu-
lously defined and every operation must conform to the most
stringent quality standards. The job of Quality Assurance is to
guarantee these conditions at our company.
This entails working closely with all production-tasked employees to iden-
tify deficiencies and risks in the production process and the value chain, to
eliminate their causes, and to test the effectiveness of remedial measures.
An important component of their work is to instil a lasting quality-based
philosophy amongst employees.
Furthermore, Quality Assurance must clear all components destined for
in-house processes, and approve all products leaving our production line
before customer delivery. This is ensured by internal audits as well as in-

1998 when it all started
Although our company is relatively young, we can already look
back on an eventful history. The beginnings of Sitech go back to
the period when the Beetle was still in production. Products may
have changed over the years – but our demand for perfection
and first-rate quality have remained the same.

Advanced car seats are highly sophisticated systems that pro-
tect a car’s occupants and provide a relaxed, fatigue-free dri-
ving experience. Every car seat we produce has these qualities,
persuading our customers to equip their vehicles with seats of
the highest level. Our job is to ensure that sitting in their cars
will always be a pleasure.
In order to offer customers this benefit, our experts work in close collabo-
ration throughout the product development process. During both develop-
ment and production phases, they incorporate the latest findings from ma-
terials, ventilation and accident research. Cutting-edge ergonomics and or-
thopaedics research is also exploited.
