Customized Flanges with Complex Shapes
- Tailor-Made Design: Produced strictly according to customer drawings, models, or samples.
- Wide Size Range: Custom outer diameters, thicknesses, and bore sizes for small to oversized flanges.
- Complex Geometry: Slots, keyways, special grooves and multi-step profiles can be integrated in one piece.
- Precision Machining: CNC turning, milling and drilling ensure tight tolerances and smooth sealing faces.
- Flexible Standards: Compatible with ANSI, ASME, DIN, JIS, EN, GOST or fully non-standard designs.
