FlexiMold™ 

With the Trelleborg Sealing Solutions proprietary FlexiMold™ technology, we can manufacture high-precision, large diameter O-Rings and other seal profiles. FlexiMold™ giant seals are of superior quality to those fabricated as spliced seals or made from extruded cord.

FlexiMold™ seals demonstrate the full visual and dimensional integrity of a molded product. Produced without the need for a dedicated tool, a flexible tool set-up minimizes lead times and costs.

The FlexiMold™ process is recommended for O-Rings and other seal profiles over 600 mm/ 23 inches. Seals are supplied to standards ISO 3601-1, AS568, and JIS B 2401 and can be produced in almost all 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.

Our unique and focused range of leading-edge materials delivers exceptional sealing integrity in critical semiconductor processes.

Material options for semiconductor sealing include Isolast® PureFab® Perfluoroelastomer (FFKM), Resiflour™ PureFab® range of premium Fluoroelastomers for high purity and low trace metal content as well as other Fluoroelastomer (FKM) grades, where process chemicals are less aggressive.

Seals are produced to a ‘zero’ defect quality policy with parts packaged and labeled individually. Class 100 (ISO 5) Cleanroom washing and packing is available, as is an express delivery service.

Large O-Rings and seals have many applications in the semiconductor industry with the production of Flat Panel Displays (FPD) for the electronics industry being a major application.
