Precision Tube Flaring & Swaging Capabilities
Our CNC-controlled flaring equipment delivers consistent, leak-free connections with support for SAE standards, custom geometries, and multi-stage operations.
Precision Flaring
CNC-controlled flaring dies create consistent flare angles (37°, 45°, 90° SAE standards) with ±0.1–0.2 mm dimensional accuracy for reliable sealing.
Swaging & Expanding
Hydraulic or CNC swaging expands tube OD or reduces ID for interference fits, barbed connections, and crimp sleeves.
Custom Geometries
Double flares, stepped swages, and complex multi-stage operations to meet application-specific connector requirements.
Flare Design & Manufacturing Process
Specification & DFM Review
Flaring and swaging performance depends on precise geometry, material properties, and connector interface. Our engineers review your specifications to recommend optimal tooling and parameters.
We provide design feedback on flare angles, clearances, and connector compatibility to ensure leak-free sealing and reliable assembly.
- Tube material, OD (outside diameter), and wall thickness
- Flare or swage type: angle, dimension, and position on tube
- Multiple flares or swages: location and sequence
- Connector interface specifications (SAE, ISO, or custom)
- Surface finish and cleaning requirements
- Quantity and delivery timeline
Flaring Workflow
- Tube Preparation — Clean ends, remove burrs, and precisely position in flaring vice
- Die Selection & Setup — CNC flaring machine loaded with correct die geometry (37°, 45°, 90°, or custom)
- Controlled Flaring — Hydraulic or servo press applies precise force to form flare angle and dimension
- Quality Verification — Flare angle, OD dimension, and bore checked; connector fit-test on sample parts
