At Kastaş, we research the future of sealing and develop innovative sealing technologies,
as R&D is the main driver of our growth and at the center of our main strategic goals.

Our R&D team, specialized multidisciplinary, carries out the activities with the aim of
developing advanced sealing technologies and efficient solutions.

Our R&D activities consist of design development, material development, process
and production technologies,and tests and simulations, all of which are run by an experienced team.
As our aim is to continue developing products based on innovative designs and high-performance materials,
we are committed to investing in advanced production technologies which will boost our quality and efficiency.


Design Development is one of two main pillars of high-performance product development,
and is carried out by the Kastaş R&D team according to the market and customer expectations using
the advanced software available in our test center. As a result, we are able to offer
new and unique designs, customer- or project-specific solutions, as well as improvements in standard product lines.


Whether working on a standard product or customer-specific project, we design sealing elements and molds using most advanced 3D design, mold flow and software tools, according to the technical requirements of the application, product design and production plan.


Simulating the newly developed design alternatives in different working conditions before prototype production reduces the development costs while increasing R&D efficiency and productivity. The staff at the R&D center perform FEA on new designs, during product design optimization, and as a means of verification of customer-specific demands before physical tests.


Material flow, fiber orientation, and directions are simulated in the injection mold using Moldex3D and Digimat programs. The analysis results are used to prevent errors in production processes and achieve productivity enhancements, thus resulting in a superior performance of our sealing and guiding elements.


Both standard and special designed products are tested at the Kastaş Test Center using software simulations and also advanced test-benches for various applications, while using precise application parameters in order to validate the design and material developed.


Kastaş R&D aims to develop advanced elastomer, polymer and composite materials for use in its future sealing technology designs.


With its experience and state-of-the art R&D infrastructure, Kastaş develops elastomer materials that set new standards in sealing technology. High-performance elastomer compounds for increasing requirements in fluid power and special materials for specific applications are developed and tested in-house and are certified by accredited laboratories.


Combining in-house laboratory research with co-engineering studies with international suppliers, Kastaş is committed to the material science R&D, with the aim of developing new high-performance polymer materials.


Established in 2006, Kastaş Test Center relies on various test benches and equipment for performing lifecycle and performance tests, such as hydraulic-pneumatic piston and rod tests, wiper and guide ring tests, high pressure, and low- and high-temperature tests.

Product tests, especially as a part of new product development, existing design optimization, new raw material performance analysis, customer-specific working conditions verification, and competitor benchmark tests, are conducted at the Kastaş R&D center.

As Kastaş, we are continuously investing into advancing the capabilities of our Test Center.
