A large step in size, a giant leap in sealing technology from Trelleborg Sealing Solutions

Trelleborg Sealing Solutions introduces FlexiMold™, its newly developed proprietary technology for the manufacture of high precision, large diameter O-Rings and other seal profiles. FlexiMold™ giant seals are of superior quality to those fabricated as spliced seals or from extruded cord and demonstrate the full visual and dimensional integrity of a molded product. Produced without the need of a dedicated tool, a flexible tool set-up minimizes leadtimes and costs.

Large O-Rings and seals are used across all process industries including Chemical and Hydrocarbon, Pharmaceutical, Food and Beverage, with the production of flat panel displays for the Electronics industry being a major application. The conventional method of producing large diameter O-Rings and seals is by splicing extruded cord. However, inherent in this method of fabrication is a weakness at the join, along with poor surface finish and difficulty in achieving tight tolerances. Alternatively, a dedicated tool is required with its associated high investment and long leadtime.

FlexiMold™ is a new proprietary technology specifically developed by Trelleborg Sealing Solutions for manufacture of large O-Rings and other seal profiles. With it, production of giant high quality seals is possible without the leadtime and cost associated with dedicated tooling. The FlexiMold™ process eliminates the risks associated with spliced O-Rings, ensuring the full visual, dimensional and functional integrity of a molded seal.

The FlexiMold™ process is recommended for O-Rings and other seal profiles over 500 mm/ 20 inches. They are supplied to standards ISO 3601-1, AS568, and JIS B 2401 and can be produced in almost infinite diameters. If O-Rings are of a standard cross section, there is no tooling charge. Larger and special cross sections along with other seal profiles can be requested.

FlexiMold™ giant O-Rings are available in a wide range of elastomers including Isolast® FFKM, Resifluor™ High Performance Fluoroelastomers, FKM, EPDM and HNBR. Compounds conforming to FDA, USP Class VI, and Explosive Decompression Resistant (EDR) requirements can be supplied. In addition, seals are produced to a ‘zero’ defect quality policy with parts packaged and labeled individually. Class 100 Cleanroom washing and packing is available, as is an express delivery service.
