Custom machined seals are high-precision sealing components produced by FOREVER SEALS via CNC precision machining, fully customized for customers' working conditions and equipment parameters. As a professional high-end sealing solution provider, we take Spring Energized Seals  as our core product, and also supply a full range of medium and high-end conventional custom seals. Our products are widely used in LNG, oil & gas, petrochemical, compressor, semiconductor, automotive, medical equipment and hydraulic/pneumatic systems that require resistance to extreme temperatures, high pressure, corrosion and vacuum.

FOREVER SEALS boasts an ultra-wide machining range for Spring Energized Seals: inner hole 1mm to outer diameter 2m (overall seals up to 3m), and we can customize any size/section within 3-2500mm with 180+ modifiable standard turning sections. Our optional materials include PTFE, modified PTFE (carbon fiber/copper powder/graphite filled), UPE, PEEK, PU, NBR, FKM, etc. We specialize in custom modified Spring Energized Seals, and also process conventional seals like PU Y-rings/dust rings, with all products supporting sample processing and personalized customization.

FOREVER SEALS selects high-quality imported raw materials for custom CNC machined seals, with a focus on premium materials for core product Spring Energized Seals to ensure excellent performance under harsh working conditions. We cover a full range of high-performance sealing materials, and can provide targeted material customization according to customers' actual application requirements. The optional materials are as follows:

● Polyurethane: PU.

● Rubber: NBR, FKM/FPM, Silicone(VMQ), EPDM, FFKM, Neoprene, HNBR, Fluorosilicone (FMVQ).

● Engineering Plastics & Modified Polymers: PTFE, modified PTFE (filled with carbon fiber/copper powder/graphite/polyphenylester/PI/molybdenum disulfide), POM, UPE, PEEK, PCTFE.

All raw materials have superior physical and chemical properties, and we can carry out personalized material matching and processing for Spring Energized Seals based on actual working conditions such as temperature, pressure, medium corrosion and friction requirements, to ensure stable and reliable sealing performance of products in different application scenarios.

FOREVER SEALS has an ultra-wide and high-precision CNC machining range for custom seals, with more mature and professional processing capability for the core product Spring Energized Seals, covering both standard and non-standard specifications to meet the diverse customization needs of customers in different industries.

● Machining size range: The inner hole of Spring Energized Seals can be processed from 1mm to an outer diameter of 2m; the overall custom seals can be processed up to an outer diameter of 3m, and all sealing elements with any size and cross-section within 3-2500mm can be customized.

● Tolerance precision: Micron-level strict tolerance control is achieved, with dimensional tolerance controlled at ±0.01mm and geometric tolerance at ±0.02mm, far higher than the industry standard.

● Processing adaptability: We have more than 180 kinds of standard turning cross-sections, all of which can be modified and optimized according to customer drawings and actual application requirements, suitable for the processing of various complex structural seals.

Customized machining solutions can be provided for over-specification size requirements of Spring Energized Seals and other custom seals to fully match the special sealing needs of high-end equipment.
