High speed blanking press

The Problem

High speed blanking press

A high speed strip-fed press used to blank electrical trip-catch components generated operator noise levels of 101dB (at 270 strokes/minute) in a relatively quiet area.

The Solution

Notes

Carefully designed local vibration isolation and damping can be very cost effective noise control techniques where structural vibration has been diagnosed as the major source of radiated noise. Care must be taken in the selection of the mounting frequency and mounting technique to avoid significant structural resonances.

The Results

An overall noise reduction of 9dB at the closest operator position was achieved. The modifications had no effect on normal machine operation, access or maintenance.

The Costs

£45 for materials.
