Tube End Forming & Shrinking Machine

A core-bar inserted during the swaging cycle holds the tube’s inner diameter to ±0.05 mm across a Φ1.9–Φ10.0 mm range. This tight tolerance means downstream brazing or welding joints seat correctly the first time, cutting scrap and rework costs at the assembly station.

Four dies engage the tube simultaneously, distributing radial force evenly instead of concentrating it on two contact points. The result is a rounder, smoother finished end with less material stress — and measurably lower noise on the shop floor, improving operator comfort during sustained production.

The forming head housing is cast rather than fabricated, providing superior vibration damping and long-term dimensional stability. Combined with specially designed forming dies, this construction extends tooling life and keeps part-to-part consistency high across hundreds of thousands of cycles.

Tube loading is manual with foot pedal activation, giving the operator full control over positioning before each cycle. The integrated digital control panel allows quick parameter adjustments, and the enclosed base keeps hydraulic and electrical components protected and accessible for maintenance.

At just 1.1 kW motor power and a 700 × 500 mm footprint, the machine integrates into tight production layouts without costly infrastructure changes. The electrical system can be configured to local voltage and frequency requirements for international deployment.
