As Tunç Automotive, we flawlessly bond the corner joints of rubber sealing profiles (door, window, trunk, and cabin gaskets) originating from extrusion lines using our high-tech corner welding molds and injection presses. We specialize in manufacturing frame-type gaskets required especially by the automotive, heavy machinery, defense, and rail system industries, where 100% water and dust tightness must be guaranteed.
High-Strength Injection Splicing: Rather than relying on simple adhesive bonding, we connect the corners of rubber profiles at a molecular level. By injecting raw materials (EPDM, TPE, etc.) that match the profile's characteristics inside our custom-designed corner molds, we eliminate the risk of tearing at stress and bending points.
Flawless Profile Matching via Toolroom Advantage: To prevent flash formation and cross-sectional shifting at the corner joints of complex extrusion profiles with varying geometries, we manufacture our corner injection molds with micron-level tolerances in our own precision toolroom.
Demanding Sealing and Aesthetic Standards: In compliance with automotive OEM standards, we achieve clean joints that preserve visual aesthetics at the bonding points. Our parts successfully pass lifetime endurance tests as well as high-pressure water and air tightness tests.
We deliver fast solutions through our toolroom and production teams for your frame-type rubber gasket projects, corner injection welding needs, and contract manufacturing demands across various sectors. You can contact us for further details and price quotations.
