Press Marking - Squeeze Action Presses

Press Marking Overview

Press marking is a traditional form of part marking. A machine fixtured with a type holder, numbering head or tooling die marks an entire word or legend in one motion. Press marking can be used on both round or flat parts and be equipped with part feeding systems for full automation operations.

Squeeze Action Presses

SCHMIDT's press marking machines are squeeze action, offering a gentler marking action when closer control of stamping pressure is desired. There is no hard impact, no bounce, and no repercussion as the marking pressure is delivered in a straight, smooth squeeze. SCHMIDT's squeeze action marking presses, with 5 to 15 tons of marking pressure, eliminate impact and reduce noise. By comparison to impact marking presses, these units are dramatically gentler for both the parts being marked and the tooling in the machine.

SCHMIDT offers two styles of squeeze action marking presses, the pneumatic Model A/O (air over oil) and the bench style Model 450. Our Model A/O (Air over Oil) marking press combines both pneumatic and hydraulic pressure to create an impact and squeeze action press all in one. These systems are available in 6 or 10 tons. The Model 450 is a more heavy duty pneumatic marking press and is available in four sizes.

Pressure Requirements for Marking

Pressure to mark one Sharp Face character (in tons)

In order to estimate marking pressure requirements, multiply the single character tonnage by the number of characters to be marked. To mark half depth, multiply tonnage requirements by 0.75; to mark two times the depth, multiply the tonnage requirements by 1.33; to mark three times the depth, multiply tonnage requirements by 1.7.
