The Power Line

In two-stroke clinching, the material to be joined is first deformed plastically inside a die. In a second phase, the joint is created through a squeezing between the punch and anvil outside of the die. The result is a high quality joint in terms of shape, strength and repeatability.

What's Included:

A complete ASTRACLINCH Power Line unit consists of a compact workhead connected through a hydraulic hose to an air-over-oil pressure intensifier (booster) with automatic cycle control, ready for connection to the
factory compressed air net. An air preparation unit with pressure regulator, filter and water trap, a variety of tool kits, balancer and rotator are available as options.
