Flexible seal - Import export

O - ring seal as flexible perfection To determine which O - ring can be used , only a few important operating parameters must be defined . The temperature , the pressure and the indication of the chemical resistance determines the selection of the correct O - ring at the right application. O - rings from Billi - seals are distinguished , depending on the material , by high thermal stability, good chemical resistance and good low temperature flexibility.

With automatic continuous punching machines, machine and tool merge into a high-performance system with high output and remarkable flexibility. Whether sealing profiles for the automotive industry, applications for furniture, or household appliances – complex trimming is often required here. Thanks to the Metzner automatic throughfeed punching machines, processing operations such as contour cutting, drilling and milling can be integrated into a throughfeed system. All these machines store all machining parameters and machine settings in a machining recipe. When starting production, an integrated barcode scanner activates all presettings on the basis of the working papers and simultaneously reports the correct tool and material on the machine display. The barcode also contains the required quantities and lengths. Thanks to well thought-out quick-change systems, tools and materials are generally changed within no more than 30 seconds, minimizing downtimes.

Dryflex CS is a range of thermoplastic elastomer (TPE) compounds, based on SEBS. The range has been engineered to deliver optimised compression set performance. The raw materials used to manufacture Dryflex CS compounds are compliant with major food contact regulations (food contact statements available on request). The compounds also offer excellent organoleptic performance. What is Compression Set? Compression set is the measure of permanent deformation remaining when an applied force is removed. A TPE sample is compressed to a specific deformation, for a specified time and at a specific temperature. The compression set value is the percentage of the sample that fails to recover to its original height and is an important performance indicator for applications such as seals, flexible connectors and gaskets. For a 40 shore A hardness TPE, typical compression set values are 65 to 70 percent, with the Dryflex CS range this is reduced to 40 percent (22 hours at 100 degree). Key Chara
