PITTSBURGH—"Accuracy, repeatability and productivity." These are the key features of a new instrument in seal testing—dubbed a "generation leap" from its predecessor.
H.W. Wallace & Co Ltd. launched its new WAC11 Mk5 testing equipment, which measures the compression stress relaxometer characteristics of rubber and elastomer products such as seals and O-rings. The new testing equipment follows the company's Mk4 instrument.
CSR—used in industries such as aerospace, automotive and construction—is a "relevant standard" to measure the durability of an elastomer seal when held in compression over time in different environments, Surry, England-based Wallace said in an October press release.
"The stress at the interface between the elastomer and the rigid faces is important for efficient sealing and is a function of the modulus of the elastomer and the strain applied," according to the specifications of the new equipment.
"Seals are used in numerous applications," the company said, like pipe joints or engine seals. "For safety, warranty and product liability reasons, it is essential that these components, whilst under compression, operate without failure for many years."
Therefore, it is important to maintain "accuracy, repeatability and productivity," on which Wallace prides itself, Chris Mundy, sales and service manager at Wallace Instruments, said in the press release, adding that the company's engineers "are continuously innovating to support our thousands of customers in managing the cost of quality and new product development."
