CEN/TC 145/WG 2 - Compression moulding machines - Safety

This European Standard specifies the essential safety requirements for compression moulding machines and transfer moulding machines for the moulding of plastics and/or rubber with a closing movement more than 6 mm.
In this document a compression moulding machine or transfer moulding machine as described above is designated by the term “press” (see 3.1).
This document deals with all significant hazards, hazardous situations and events relevant to presses, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).
The safety requirements are specified for the additional hazards arising from:
- shuttle/turn tables used for loading/unloading and/or cooling,
- magnetic clamping systems.
For other ancillary equipment, as defined in 3.7, that is not part of the press, only the requirements for the interaction between presses and ancillary equipment, especially loading and unloading devices are specified.
The following machines or units are excluded:
- pneumatic presses for plastic and rubber;
- injection moulding machines (see EN 201:2009);
- tyre curing machines (see prEN 16474);
- presses for curing inner tubes and curing bags;
- hydraulic presses for the cold working of metals as covered by EN 693:2001+A2:2011;
- mechanical presses for the cold working of metals as covered by EN 692:2005+A1:2009;
- pneumatic presses for the cold working of metals as covered by EN 13736:2003+A1:2009;
- thermoforming machines (see EN 12409:2008+A1:2011);
- reaction injection moulding (RIM) machines (see EN 1612 1:1997+A1:2008);
- the extruder of the carousel machine(see EN 1114 1:2011).
This standard does not cover:
- hazards caused by the processing of materials which may lead to a risk of explosion, see 7.2.2;
- the requirements of Directive 94/9/CE concerning equipment and protective systems intended for use in potentially explosive atmospheres;
- requirements for the design of exhaust ventilation systems, see 5.3.5 and 7.2.8.
This document is not applicable to presses manufactured before the date of its publication as EN.

This document specifies the essential safety requirements for hydraulic presses, including toggle and hydro-mechanic ones, with a vertical closing movement more than 6 mm for the moulding of plastics and/or rubber.
This document covers both compression moulding (see 3.1.1) and transfer moulding (see 3.1.2).
All hazards listed in clause 4 are covered by this document.
The following machines are excluded:
-   injection moulding machines (see EN 201);
-   presses for curing pneumatic tyres;
-   presses for curing inner tubes and curing bags;
-   hydraulic presses as covered by EN 693;
-   mechanical presses as covered by EN 692;
-   thermoforming machines (see EN 12409);
-   RIM machines (see EN 1612-1 and EN 1612-2).
The safety requirements for the additional hazards arising from the interaction between presses and ancillary equipment especially loading and unloading devices are specified. The safety requirements for the ancillary equipment itself are not specified.
This document does not cover:
- the requirements of Directive 94/9/CE concerning equipment and protective systems intended for use in potentially explosive atmospheres;
-   requirements for the design of exhaust ventilation systems.
This document is not applicable to presses manufactured before the date of publication of this document by CEN.
- RIM machines (see EN 1612-1 and EN 1612-2).
