The Problem

CNC punch press

Three large CNC punch presses were generating high levels of noise in an otherwise 'fairly' quiet workshop area.

The Solution

An in-house designed acoustic enclosures constructed on site by a local contractor consisting of:

  • 20mm MDF either side of wooden frame
  • 100mm cavity packed with mineral wool
  • External skin of 12.5mm plasterboard with plaster skim
  • 10mm 'double glazed' Perspex viewing window
  • Standard U-section sliding door with brush seals with interlock system
  • Externally mounted machine controls
  • Full modular construction enabling maintenance and removal of machines
  • An interlock door system negates the need for light barrier or a pressure-sensitive pad safety system and lowers insurance premium.

The Results

Measured internal to external field level difference of 25dB resulting in a much quieter workshop environment.

The Costs

Approximately one third of the price of standard commercially available industrial metal acoustic enclosure system.
