Autofrettage is a method for increasing fatigue strength of components for use at high and pulsating pressures. In short, Autofrettage compresses a container’s inner surface, making better use of the material’s structural properties. The process can reduce fatigue concerns in pulsating applications and lets engineers reduce tubing thickness in high-pressure applications without sacrificing strength, life, or safety. The autofrettage method is based on the reciprocal relationship of the plasticized inner zone and the elastically deformed outer zone. The components are placed under so much pressure that their interiors become plastically deformed. After relaxing, pressure stresses are created in these areas, which prevent the outer areas from reforming to their original shape. Instead, it remains stretched. This prevents crack formation in the later application, increases the service life of

The Poppe + Potthoff impulse test stands test the operating or fatigue strength of various metal and plastic components. The endurance test in our high-pressure test systems simulates the life-cycle under varying loads. The failure tests thus show the potential weaknesses of the components with respect to design and material. The pressure is optionally modulated as a sine wave, trapezoid curve or needle pulse. Our test stands are characterized by a special ergonomics and are designed by Poppe + Potthoff machine design. Due to our flexible modular design, our machines are very variable, so that the pressure and volume range is designed according to the customer’s requirements. Of course, our systems are UL or CE compliant as required. In addition, we offer you service and support directly on-site.

With the dual chamber PPM leak test stand, Poppe + Potthoff Maschinenbau offers a powerful system for testing sensors in medical device industry. The test stand can be implemented in R&D processes, but also during production as an end of line test. With pressures of up to 50 bars this equipment offers a large spectrum of testing opportunities in the medical area. Some Global Test Standards include: ISO 14644 ASTM G122-96 ASTM D6361 SAE AMS 0302 The PPM leak test stand is able to be programed to the customers requirement. The powerful in house built software enables exact design of pressure curves, such as holding times and exact pressure increase over time. It is an ideal solution for any sorts of plastic components. This exemplarily displayed test bench can utilize air or nitrogen as a test medium. Please get in touch about any other test mediums. In addition the PPM test benches can perform tests of multiple test units at a time.
