Our company established in 1983 as a small workshop, was corporated in 2003 and got the name of KAYALAR YAY SAN. TİC. LTD. ŞTİ. With 37 years of experience and perseverance, it has become a respected company of Turkish industry not only in terms of production but also in quality of production with international technology, expert staff and wide machine park.

Whether laser cutting, folding, welding, powder coating, assembly or much more - you are exactly right with us. Combined with our motivation and flexibility, we offer you a powerful overall package for the production of high-quality sheet metal products and assemblies.

We produce in Trimmis - from advice and planning through production to distribution, we handle everything from a single source. We are a full service provider in sheet metal processing.

Keller Laser AG in Trimmis, Graubünden, has been in existence since 1995. Thanks to high-precision and modern systems, we have been forward-looking and motivated by technical developments in our industry. "Together with quality to success", this is our motto. And with fairness, competence and environmental awareness.

Liegau-Augustusbad is located in the vicinity of Dresden/Saxony, with perfect logistical connections to the motorway and Dresden airport.

The Company’s manufacturing area is around 26,000 square metres and has been producing a wide range of moulded rubber components since the early 1900s.

As a result, we have gained extensive knowledge in the field of rubber processing and parts manufacturing. Due to the fall of the DDR, the Company was later privatised in 1991, with large investments made in a more modern manufacturing process and extension of the machine park.

The KET has currently around 50 highly skilled and motivated employees, enabling us to work a 3 shift system in order to fulfil our customer’s needs, whether it’s a Simple form or a complicated Moulding, we aim to please.
Through our quality management system DIN EN ISO 9001 and DIN ISO 13485 certification. We are able to guarantee a very high level of customer satisfaction and quality of our products.
Our technology department control and monitor the preparation, introduction and implementation of our production processes according to clearly defined specifications. The most important operating procedures we use within our production processes are:

• 3-D-printing/Plotting
• compression moulding process (CM)
• transfer moulding process (TM)
• injection moulding process (IM)
• injection transfer moulding process (ITM)

The vulcanisation operating processes are carried out in semi and/or fully automatic machining cycles.

We also offer a number of procedures and technologies for the post-treatment of produced products (finishing):

• thermal post-treatment (Curing)
• mechanical post-treatment (low-temperature deburring)
• manual post-treatment (hand deburring / assembly)
• covering and coating processes
We manufacture parts from rubber compounds such as EPDM, NBR, SBR, CR, ACM, NR, FPM, IIR, MVQ and LSR (silicones). All of which have received clearance from the automotive industry, as well as KTW and DVGE clearance for the food and pharmaceutical industries. In addition to rubber vulcanisation, we also manufacture a large quantity of thermoplastic elastomers (TPE). Another key feature of the materials sector is the use and manufacture of recycled rubber granulates from various basic elastomers
The equipment and control systems of our Machine Park reflect the current state of the art in engineering, thus Enabling us to meet the future requirements of production engineering. We can manufacture parts from less than 1 Gramm up to 4,5 Kilograms.
