Sealing technology manual for the process industry - Freudenberg Xpress

MARKET-SPECIFIC SERVICES Delivery of replacement parts in re- cord time When a seal fails during the produc- tion process and a replacement part is not in stock, every hour counts in order to prevent costly machine downtime. Freudenberg Xpress can normally find a remedy within 24 hours. On the basis of a drawing or a sample, the seal can be machined and sent without de- tours directly to the location where it is required. Rapid prototyping The term “rapid prototyping”, i.e. the rapid production of functional models, is in actual fact not applicable to elas- tomer technology. Nevertheless, the specialists at Freudenberg make ex- actly this possible. Thanks to the pro- duction of prototypes without stand- ard tools, sample parts can be created that can be tested and optimized until the best solution has been found. This reduces the development time of new plants while minimizing the financial outlay. Economical short runs Machining technology cannot be a pro- duction method equivalent to series production. From a certain annual quantity, the investment in mass pro- duction tools becomes worthwhile from an economic point of view. How- ever, by temporarily switching to ma- chining technology, small batches can be processed, the manufacturing time of mass production tools can be bridged, and market fluctuations with stagnating demand can be responded to. THE ADVANTAGES AT A GLANCE • Production of prototypes to shorten the development time • Fast remedy in the event of defects • Economic production of small batches without series production tools • Original Freudenberg materials with approvals such as 3-A® Sanitary Standards and USP Class VI, as well as FDA conformity • Almost the same mechanical prop- erties as those of mass-produced seals • Unique surface quality • Long service lives The Freudenberg Xpress service can provide seals in original quality within a few hours using the latest CNC technology. Freudenberg Xpress is the best choice not only for the quick delivery of replacement parts, but also for the economic production of small series. Thanks to state-of-the-art manufac- turing facilities and in-house machin- ing tools development, Freudenberg has achieved a unique surface quality with a mean roughness index of max. Ra = 2.38 µm (roughness depth Rt = 13.7 µm). This value is approximately equal to that of a conventionally pro- duced seal. You can find an overview of materials suitable for machining technology on page 32 f. The lip edge is created by cutting, which is a complex process and therefore rarely applied in the mar- ket. The machined seals of Freuden- berg achieve an exceptionally long service life. FREUDENBERGXPRESS Introduction 6
