Thermo-Viscoelastic Testing of Polymers
Creep and/or stress relaxation tests are routinely conducted for clients in the medical and consumer-products industries.
Environmental Stress Cracking and Physical Aging Tests
Stress Engineering is uniquely tuned to the plastics industry’s need for management of ESC and physical aging.
Instrumented Drop Impact Testing
Both plastic components and packages are subjected to drop/impact loading specifications in almost every segment of this industry.
Hot-Fill/Retort Packaging Test Systems
Coupled thermal and structural loading combined with head space pressure or vacuum loads are very common in hot-fill and retort processes.
Biaxial Testing (Bubble Rheometer)
The biaxial inflation test system at Stress Engineering is a unique device that was developed in our lab.
Fatigue Life Testing for Polymers
Stress Engineering has a great deal of experience in life prediction and testing, and our engineers apply this expertise to assessment of polymers on a routine basis.
High Strain-Rate Tensile Impact Testing
Impact-related failures in plastics and packaging comprise a class of challenging materials-failure problems that are highly dependent on strain rate, operating temperature, and design geometry.
Seal Testing
Testing potential seal materials to generate a "seal contact pressure envelope" is key to effective seal system design, and Stress Engineering is a pioneer in seal design for plastic components.
Custom Test Systems
Companies in the plastics and packaging industry are often developing unique products that feature new performance-related functions.
Tensile/Compression Testing
Stress Engineering routinely conducts tensile and compression tests on a wide range of polymeric and elastomeric materials for characterizing material properties.
Friction Testing
Measuring static and sliding coefficients of friction is a critical part of accurately calculating the functional attributes of plastic assemblies.
Container and Packaging Testing: Quasi-Static Loading
Stress Engineering conducts a variety of tests on plastic packaging for evaluating structural response under various loads on the manufacturing line and during shipping, distribution, storage and handling. |
