GT Schmidt 5-T Hydro-Pneumatic Marking Machine | 10,000 Lb Force | 1998

Geo. T. Schmidt Model 5-T Hydro-Pneumatic Marking Press | 1998 | 5-Ton

The Geo. T. Schmidt Model 5-T is a precision hydro-pneumatic (air-over-oil) marking press designed for permanent product identification and high-speed indenting. Unlike traditional impact markers that use spring-loaded hammers, the 5-T utilizes a smooth "squeeze" action to deliver up to 5 tons (10,000 lbs) of marking force. This results in superior depth control, near-silent operation, and significantly longer life for your marking stamps and type.

This 1998 unit (S/N 12305) is equipped with a Schrader Bellows "Superspeed" pneumatic cylinder for rapid cycle times and was originally part of a custom assembly setup. Its compact footprint makes it ideal for benchtop marking or direct integration into automated production lines for marking steel, aluminum, and industrial nameplates.
