An injection molding machine is a machine that produces plastic parts from plastic in granular form. For this purpose, the required molding compound is prepared in the injection unit and injected into a die, which represents a negative mold (cavity) of the desired plastic part. Depending on the process used (thermoplastic injection molding, thermoset injection molding or elastomer injection molding), various components of the machine are heated or tempered. Injection molding machines generally consist of two parts: The injection unit, which prepares the raw material and injects it into the mold under pressure, and the clamping unit, which receives the mold and opens and closes it.
An injection moulding machine is a machine that produces plastic parts from plastic granulate.

Depending on the process used (thermoplastic injection molding, thermoset injection molding or the elastomer injection molding), various components of the machine are heated or tempered. In this application, the injection moulding machine is located in a clean room. Medical plastic parts are produced.
A plastic film printed in gravure, e.g. OPP, is cut lengthwise into several batches on the slitter rewinder. The individual batches are as wide as a downstream packaging machine. However, these are transported to another packaging plant. The winder is the last machine before this film goes to the packaging plant. To avoid complaints due to electrostatically charged film, the film must be discharged in the best possible way in the slitter rewinder. As proof, the residual charge on each film is measured and recorded.
Suction pipes are used, for example, to transport punching or cutting waste from a printing press via a pipe system to a waste disposal facility. The same applies to edge trim suction in plastic film production. The material waste is compressed in the stationary compactor and then transported to the transport container. The full container is transported away by truck.
A shrink sleeve film is unwound on a cross-cutting machine and then cross-cut. The cross-cut films are placed in a shed on a conveyor belt. Afterwards, small film packets are formed from the scale by hand. The packets are placed in a box.
The system cleans plastic parts for automotive headlights. The machine operators place plastic parts from an injection molding machine into a rotating holder of a cleaning module. The cleaning module rotates the parts in front of the cleaning system. Before the car headlights are assembled, the electrostatically charged plastic parts are discharged and cleaned.
On a turret winder downstream of a film extrusion line, the film is cut lengthwise onto several panels and wound up. When the reel is full, an automatic reel change takes place. During a winding change, the film must continue to run and the next film winding must be started properly and without creases.
In the production of a container, 4 drums filled with different substances are placed individually next to each other on a pallet. The substances are sucked in with a suction nozzle and transported further via pipes. During the suction process, the substances and the barrel are electrostatically charged. The drums must therefore be grounded and the ground connection monitored. The application is located in the EX-area!
With a grinding material suction system, there are problems with electrostatically charged grinding material. The regrind material is sucked in via a hose with an outer diameter of approx. 72 mm and is electrostatically charged in such a way that the material partially adheres to the metal funnel and does not fall down. As a result, the entire system becomes clogged and cleaning-related downtimes occur.
A blown film is a film made of a thermoplastic material, which is produced with the help of a special blown film extrusion line. The way it works is that molten plastic is blown out of a ring-shaped nozzle with the help of air. The solidified tube is folded by a pair of rollers at a height of 10-20 metres. At the end of the line, the film is cut lengthwise and usually wound separately on two winders. Typical machine speeds are around 10-20 m/min. These continuous films are mainly used for packaging food, medical products or in the pharmaceutical sector.
