Mechanical press PMX-S4 series

formingstampingfor sheet metal

Overview
The PMX-S4 Series comprises mechanical 4-point straight-side presses designed for progressive-die forming. The tie-rod frame features very low deflection and bearings with minimal clearances to limit breakthrough, reduce noise and extend die life. Slide suspension point centers are positioned close to the tie-rod centers to optimise multi-process forming and resistance to eccentric loads. Built-in dynamic counterbalances reduce vibration and enable stable high-speed production.

Key features

• Forged eccentric shafts mounted on a very low-deflection tie-rod frame with dynamic balancing of slide and upper die
• Built-in dynamic counterbalances for vibration reduction and stable high-speed operation
• Wide spacing between support points to resist off-center loads
• Highly rigid, symmetrical frame suitable for progressive stamping of thick sheet metal
• Slide suspension centers located close to tie-rod centers to support multi-process forming and heavy eccentric loading
