Various plastic parts, the circuit board and LED modules are put together on an assembly line for different car headlights.

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.

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.

An injection moulding machine is a machine that produces plastic parts from plastic granulate. For this process, the required molding compound is prepared in the injection unit and injected into a die, which represents a negative mold (cavity) of the plastic part. 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.

Static electricity is invisible to the human eye.

During the processing and finishing of materials which are insulating in one form or another (e.g. paper, textiles, glass, wood, chemicals, plastics), electrostatic charges are inevitable. Charges develop when materials are processed and rub against one another, or when objects formerly in contact are suddenly separated, or when materials are joined, bonded, glued or welded. The problem lies not only with the materials, but with the energy used to move these materials, whether they are solids, liquid, gases or powders. The higher the speed is, the more trouble the electrostatic charge can cause.

Uncontrolled electrostatic charges are always undesirable and can impede the efficiency of manufacturing processes. On the other hand, controlled electrostatic charges – purposely applied – improve manufacturing efficiency by using electrostatic properties to accomplish something beneficial in the process.

Whether too small to see or a bolt of lightning, the spark is a typical phenomenon that accompanies electrostatic discharges. Eltex has the expertise and the engineering skills to measure, control, eliminate and utilize these elemental forces.
