The injection molding machine manufacturer ENGEL is improving employee safety in plastics processing with its safety guarding according to EN ISO 14120. Its modular concept supports straightforward configuration and installation. Thanks to the extensive selection of safety panels and functional elements such as control cabinets, cable ducts, and swivel and sliding doors, individual layouts can also be realized at reasonable cost.
A machine operator trips while walking through the production hall and falls against the safety guarding of a production cell. This scenario is simulated according to the EN ISO 14120 standard by a defined pendulum test with a 90 kg sandbag. Naturally the safety guarding has to withstand this test without being breached. This standard replaces the old EN 953.
EN 953 merely prescribed a “certain mechanical strength” but did not define this further. The new standard on the other hand provides concrete information on the load capacity from the outside to the inside, and defines both the test procedures and the conformity criteria. This makes it possible to compare the information from different safety guarding manufacturers.
In developing the safety guarding, ENGEL Austria GmbH set the goal of not only meeting the requirements of the new standard reliably but also improving flexibility for the user. As a provider of system solutions including injection molding machines and automation, ENGEL considers the free-standing safety guarding an essential component of the production cell. That is why the existing version of the safety guarding is being replaced by an easy to install modular solution. With the modular structure, the solution also meets future requirements arising from increasing process integration and automation.
