Mixing Room

Rubber compound manufacturing is carried out by blending polymers, fillers, oils, and chemical additives in carefully controlled proportions. During the mixing process, a customized formulation is developed to achieve the desired properties, including hardness, elasticity, abrasion resistance, and resistance to aging. After a conditioning period, the compound is prepared for further processing through extrusion or molding operations. Proper formulation and precise process control are essential to ensuring the performance and quality of the final product. Depending on customer requirements and product specifications, all rubber compounds are formulated and produced in-house using the highest-quality raw materials, supported by more than 35 years of industry experience and continuous R&D expertise.

Mold Design and Machining

In the design of rubber extrusion dies, the material’s flow characteristics, swell rate, and required profile tolerances are carefully considered to create the optimal channel geometry. Flow paths within the die are balanced to ensure uniform material distribution throughout the profile. Tool steels are typically used during the manufacturing process, while precision dimensions are machined using CNC technology. Surface finishes are further optimized through polishing processes to enhance material flow performance and improve the quality of the final product. Accurate die design and precision manufacturing are critical for maintaining profile dimensional stability, surface quality, and overall process efficiency. All die designs are developed in-house by our experienced engineering team using advanced 2D and 3D design tools, supported by numerical simulation and analysis software. Through these integrated design and manufacturing processes, we have developed a portfolio of more than 1,000 die variations. This extensive expertise enables us to provide fast, flexible, and customized solutions while working closely with our customers to meet their specific requirements

Extrusion

Rubber extrusion is a manufacturing process in which a prepared rubber compound is continuously forced through a die under controlled pressure and temperature conditions using a screw and barrel system. This process enables the continuous production of profiles with the desired cross-sectional shape, including seals, gaskets, hoses, and various sealing profiles. During the extrusion process, flow stability, temperature control, and line speed are critical parameters for maintaining precise dimensional tolerances and consistent product quality. After exiting the die, the extruded products are vulcanized using microwave, hot-air, or salt-bath curing systems to achieve their final elastic and mechanical properties. As a highly efficient and repeatable manufacturing method, extrusion is one of the fundamental technologies of modern rubber production. With our in-house extrusion and co-extrusion lines, rubber compounds of varying hardness and density can be manufactured according to customer requirements, including products with metal carriers, flocked surfaces, and self-adhesive tape applications.

Vulcanization

Rubber profile vulcanization is the manufacturing process in which the uncured profile obtained after extrusion is cross-linked through heat and appropriate curing systems, giving it elasticity and permanent mechanical properties. This process can be carried out using various systems such as microwave, hot-air, salt bath, or steam curing lines. Precise control of temperature and curing time during vulcanization is critical to achieving the desired hardness, elasticity, and dimensional stability of the profile. With the hot-air tunnels, salt bath systems, autoclaves, and flocking processes available within our company, products are cured according to customer requirements and brought to their final performance specifications.

Finishing

Finishing operations prepare the product for shipment by encompassing processes such as cutting, punching, bonding, corner joining, surface cleaning, and quality inspection. During this stage, critical characteristics including dimensional tolerances, surface quality, and sealing performance are carefully monitored and verified. Through the use of appropriate equipment and standardized processes, the functional suitability of the final product and its full compliance with customer expectations are ensured. In line with customer requirements, customized cutting, hole-punching, and welding processes are designed and carried out in-house to meet specific product needs.
