Bespoke polycarbonate machine guards

Procter Machine Safety is a leading manufacturer of high-quality, standards-compliant clear polycarbonate machine guards. We offer a comprehensive service that includes site surveys, risk assessments, stakeholder consultations, design, manufacture and installation.

Why use polycarbonate guards?

Polycarbonate guards are typically used in industries where high levels of hygiene are required, such as the food and pharmaceutical industries. Our polycarbonate guards meet all necessary requirements relating to machine safety and food health and safety.

In the food, beverage and pharmaceutical industries, polycarbonate guards withstand regular washdowns. Furthermore, polycarbonate has good impact resistance, which can be important for viewing windows within machine enclosures, for example. Polycarbonate also tolerates coolants and other process fluids.

Polycarbonate is often specified for perimeter guarding when excellent process visibility is required.

Construction of polycarbonate guards

Depending on your application requirements, polycarbonate guards can be fabricated as frameless formed or bonded constructions, or as supporting frameworks of aluminium, steel or stainless steel and infill panels of polycarbonate.

Aluminium and polycarbonate is a popular combination for the pharmaceutical industry, whereas wet environments, such as food, beverage and papermaking, typically use a combination of stainless steel and polycarbonate. Painted or powder-coated mild steel is more likely to be used for the framework when polycarbonate guards are destined for perimeter guarding, machine tool enclosures and similar applications.

Design considerations for polycarbonate guards

Our machine guarding design experts have over 250 years of knowledge and experience between them and they are very familiar with the special requirements for polycarbonate machine guards. Factors taken into account include:

  • dirt traps must be avoided if guards are for use in hygienic environments
  • correct specification of fasteners for impact resistance
  • correct thickness of polycarbonate
  • fume or heat extraction may be required for guards that fully enclose machines
  • when to specify a more scratch-resistant material than polycarbonate (eg safety glass for machine tool windows)
  • earthing of guards may be necessary to avoid a hazardous build-up of static electricity

Standards and compliance

We design, manufacture and install bespoke polycarbonate machine guards in compliance with all relevant standards including BS EN ISO 14120 and BS EN ISO 13857. Where appropriate, the guards also comply with standards specific to the type of machinery being safeguarded.

For new machines or pre-owned machines that need to be CE marked before they can be used, polycarbonate guards aid compliance with the Machinery Directive and the Supply of Machinery (Safety) Regulations. For existing machinery, polycarbonate guards can help employers meet their legal obligations under PUWER (Provision and Use of Work Equipment Regulations).
