Examples of countermeasures in the plastics industry

Utilising static elimination with a large air flow makes it possible to remove foreign particles adhered to targets even without a factory air supply.

Just one ionizer can be used to eliminate static electricity quickly over a wide area. Constantly monitoring the level of electrostatic charge, which strongly influences the adherence of foreign particles, makes it possible to improve yield rates.

Strong electrostatic charges can be generated during injection moulding. Products become defective when foreign particles adhere to them due to static electricity. These products must be disposed of. Static electricity can also cause products to stick to moulds. These products must be removed by hand, which reduces the yield. An ionizer can prevent adhesion of foreign particles and ensure that products do not stick to the mould.

Static electricity can cause parts to jam in the part feeder, resulting in feeding errors. An ionizer can eliminate this problem.

Very strong electrostatic charges occur during roll-to-roll loading. This static electricity can potentially cause problems including inability to pull off the wrapping film, staff feeling pain, sparks occurring during unwinding, or foreign particles getting stuck during wrapping. The latest ionizers from KEYENCE can eliminate these problems.

When a plastic part is cut or polished, waste material from this process remains attached to the part. To avoid damage, this waste must be blown off – an air-supplied ionizer can do just that.
