CEIA Induction Heating Solutions for the Fastener Industry
- Jamie RunevitchInduction heating is widely applied in the fastener industry to ensure precision, quality, and efficiency. By heating metals to controlled temperatures, the material’s malleability is maximized without allowing re-crystallization, grain growth, or metallurgical fractures. This improves quality, boosts productivity, and extends machine life.
Main Applications of Induction Heating in Fastener Production
1. Heating for Forging
- Used for stamping the head of screws.
- High temperature range: 950–1150°C.
- Heating localized at the rod extremity, with a length approximately three times the rod diameter.
2. Warm Forming
- Temperature range: 150–750°C.
- Inductors can be integrated directly inside the machine near the cutting station, or externally.
- Temperature depends on the metal: lower for steel, higher for titanium.
3. Pre-Heating Before Threading
- Temperature range: 300–600°C.
- The screws that have already formed require localized heating for the threading process.
- CEIA’s compact induction systems integrate easily into:
- Cylindrical 3–4 die machines (manual/semi-automatic).
- Flat die or planetary rotary threading machines (automatic).
4. Induction Hardening of Screw Threads
- Pre-heating screws to 100–300°C before applying thread-locking or sealing coatings.
- Ensures durability and performance of fasteners.
