Sealing Systems for Demanding Applications
ELDISY develops and produces functional sealing systems – precisely tailored to installation space, material requirements, and operating conditions.
What Sealing Systems Must Achieve
Function Begins in DetailSealing systems play a central role in technical applications: they protect against the ingress of water, air, dust, or other media, compensate for tolerances, and contribute to acoustic and thermal decoupling.
This is not about individual profiles or components, but about the interaction of all components within a system. A permanently reliable solution is only achieved when geometry, material, and installation situation are precisely coordinated.
ELDISY therefore consistently develops sealing systems from a system perspective – from the initial concept to series production.
Extrusion of EPDM and TPE Profiles
We manufacture extruded profiles in EPDM and TPE on state-of-the-art systems with fully automated, state-of-the-art technology.
While classic EPDM seals are primarily used in the automotive sector, TPE profiles are also suitable for technical products, such as window guides.
ELDISY develops and manufactures sealing systems such as mono- and multi-component injection molded parts for original equipment manufacturers and Tier 1 system suppliers in the automotive industry. They are used in various vehicle types and meet high functional requirements in static and dynamic applications. These include sealing, water management, and various covers.
Complex sealing systems, primarily composite profiles that optimally combine different materials, are also used in industrial applications. In this way, our sealing systems contribute to the function, safety, and longevity of devices and technical systems.
We develop customized solutions on highly modern systems with fully automated, state-of-the-art technology, using the lowest possible material and energy consumption for optimized production costs.
From Profile to System Solution
Combined Manufacturing for Precisely Fitting Sealing SolutionsModern sealing systems are created by combining various manufacturing technologies. ELDISY connects extruded profiles with injection molded parts to create precisely fitting complete solutions.
While extrusion enables continuous profiles with defined properties, injection molding complements these with precise molded parts and functional elements.
The interaction of both processes creates sealing systems that, in addition to sealing, perform additional functions such as guiding, fixing, or damping.
Well-conceived system solutions from ELDISY, which integrate seamlessly into existing assemblies and meet the highest technical requirements.
The Result:- Combination of extrusion and injection molding
- Function integration instead of individual parts
- Precisely tailored to installation space and application
Manufacturing Processes in Interaction
The requirements for modern sealing systems can rarely be met with a single manufacturing process. ELDISY specifically combines extrusion and injection molding to realize functional, economical, and assembly-friendly solutions.
Extrusion
Extrusion enables the production of continuous sealing profiles with consistent quality over the entire length. It is particularly suitable for applications where complex geometries, defined material properties, and flexible adaptations are required.
By using different materials and multi-component solutions, profiles can be specifically adapted to their function within the system.
Your Advantages
- continuous profiles over long lengths
- complex cross-sectional geometries
- Multi-component and co-extrusion
- targeted adjustment of hardness, density, and function
Injection Molding
Injection molding produces precise molded parts that are used where defined geometries, transitions, or additional functions are required. The process enables the integration of complex details and ensures reproducible quality in high volumes.
Injection molded parts often perform connecting or function-extending tasks within a sealing system.
Your Advantages
- high-precision molded parts
- complex geometries and details
- Integration of fastening and functional elements
- high repeatability
Combination of Both Processes
The actual performance arises from the combination of both technologies. ELDISY develops sealing systems in which extruded profiles and injection molded components are precisely coordinated.
This results in integrated solutions that are convincing both functionally and in terms of process – from overmolded end pieces to closed frame systems and hybrid components with multiple functions.
- overmolded end pieces and molded elements
- frame seals with defined transitions
- hybrid components with multiple functions
- pre-assembled system solutions
