Checking Safety Pane of Work Area Safety Door

The safety pane consists of polycarbonate, which is protected on the inside by single-layer safety glass and on the outside by blown film. Polycarbonate ages and becomes brittle under the influence of cooling lubricant vapors, cleaning agents and oils, which reduces its impact resistance. It is not possible to see this embrittlement! In order to protect persons in the machine surroundings, check the safety pane regularly and replace if damaged.
