Plastics and rubber machines - Injection moulding machines - Safety requirements
This European Standard specifies the essential safety requirements for injection moulding machines for the processing of plastics and/or rubber. All hazards listed in Clause 4 are covered by this standard. The following machines are not covered: - machines on which the clamping unit can only be operated by the physical force of the operator; - injection moulding machines with pneumatic drives for the platen movement; - injection moulding machines with vertical platen movements driven by an electrical axis; - blow moulding machines associated with an injection process (EN 422); - machines for reaction injection moulding (RIM) (EN 1612-1); - presses (EN 289); - footwear moulding machines covered by EN 1845. The safety requirements for the interaction between injection moulding machines and ancillary equipment are specified. This standard covers magnetic clamping systems only if: - machines have horizontal clamping units; and - the mould area is protected by guards; and - such systems are delivered at the same time as the injection moulding machine by the machine manufacturer.
Kunststoff- und Gummimaschinen - Spritzgießmaschinen - Sicherheitsanforderungen
Diese Norm behandelt die wesentlichen Sicherheitsanforderungen an Spritzgießmaschinen mit hydraulischen und/oder elektrischen Achsen für die Verarbeitung von Kunststoff und/oder Kautschuk.
Alle Gefährdungen nach Abschnitt 4 werden in dieser Norm behandelt.
Folgende Maschinen sind ausgenommen:
? Maschinen, bei denen die Schließeinheit nur durch Muskelkraft betrieben werden kann;
? Spritzgießmaschinen mit pneumatischem Antrieb für die Bewegung der Aufspannplatte;
? Spritzgießmaschinen mit senkrechter, durch eine elektrische Achse angetriebener Schließeinheit;
? Spritzblasformmaschinen (siehe EN 422);
? Maschinen für das Reaktionsgießen (RIM, siehe EN 1612-1 und EN 1612- 2);
? Pressen (siehe EN 289:2005);
? Maschinen für Schuhe nach EN 1845.
Die Sicherheitsanforderungen für das Zusammenwirken von Spritzgießmaschinen mit Zusatzeinrichtungen werden festgelegt.
Diese Norm gilt für magnetische Spannsysteme nur, wenn:
? Maschinen eine horizontale Schließeinheit haben; und
? der Werkzeugbereich durch trennende Schutzeinrichtungen gesichert ist; und
? das Spannsystem gleichzeitig mit der Spritzgießmaschine vom Maschinenhersteller geliefert wird.
Diese Norm behandelt nicht die Anforderungen an die Gestaltung einer Absaugeinrichtung.
Diese Norm gilt nicht für Spritzgießmaschinen, die vor dem Ausgabedatum der Norm hergestellt wurden.
Ein Übergangszeitraum von einem Jahr nach Veröffentlichung dieser Norm ist erlaubt, in dem EN 201:1997 noch angewendet werden kann.

La présente norme ne s’applique aux systèmes de bridage magnétique que si :
- l’unité de fermeture de la machine de moulage par injection est horizontale ; et
- l’accès à la zone du moule est empêché par des protecteurs ; et
- le système de bridage magnétique est livré par le constructeur de la machine de moulage par injection en même temps que la machine.
Le présent document ne contient pas de prescriptions relatives à la conception de systèmes d'aspiration.
Le présent document n'est pas applicable aux machines de moulage par injection fabriquées avant sa date de publication comme EN.
