Interface Performance Materials provides a full range of engineering services including gasket design, flange analysis and material recommendations, sealing problem resolution, joint design recommendations and part validation testing. Our application engineers support OEMs and their Tier 1 sealing system suppliers by taking information supplied by original equipment engineers and applying it to specific sealing applications.
We take all the initial input and perform the analysis and testing required to determine the most cost-effective solution that meets the customer’s defined criteria. We use the latest technical tools to evaluate and predict the performance of the recommended sealing solution. We eliminate all the guesswork. There is no need for re-testing or re-design work.
3-D Solid Modeling
With OEMs using solid modeling to design engines and transmissions, our engineers can now better design gaskets for those assemblies.
Finite Element Analysis, a numerical technique for analyzing stress, thermal and vibrational attributes, gives our application engineers a powerful tool for analyzing and modeling solutions.
Pressure-Sensitive Film Analysis
Pressure-sensitive film impressions of joints, which are performed using specially formulated pressure-sensitive paper, give a static load distribution measurement within a joint to reveal flange stresses on gaskets and other sealing challenges.
Design Validation and Production Approval
Our comprehensive testing capabilities provide for static and dynamic testing, accelerated aging, response to fluid exposure, heat, high thermal change rates, pressure pulsing, vibration and more. The result: OEMs and suppliers have the data to prove the gasket material meets all performance specifications.
Component or laboratory tests that are used to confirm material performance include:
- Thermal cycling:
- with high temperature/pressure fluid circulation
- with vibration
- Nitrogen sealability
- Oil and coolant sealability
- Hot compression shearing
- Friction/shear testing
- Erosion testing
- Pressure-pulse testing
- Dynamometer testing
- Customized bench testing
Once the testing has established that the OEM’s criteria have been satisfactorily met, production approval can be confirmed.
