S+S Separation and Sorting Technology has supplied metal separators of type GF Primus to Zollner Elektronik to help avoid machine downtime.

Since its foundation in 1965, the Zollner Elektronik, headquartered in Zandt, has developed from a specialist for electro technology into an international system services provider for EMS (electronic manufacturing services).

With 6,700 employees at 14 locations all over the world, the parent plant in Zandt has about 2,100 employees.

Since 2001, the production spectrum in Zandt also includes plastic injection moulding with dedicated mould and toolmaking departments.

The production hall in Zandt features 16 machines for plastics processing, which primarily produce parts for industrial electronics and for the automotive industry.

The production lines are designed for an extensive range covering small series of 500 parts per year through to annual production quantities of three million parts.

Environmental awareness, but also economic considerations, have resulted in the use of industry-quality granulate (regenerated material) for various products.

With many articles, a slight loss of properties does not prevent the use of such material.

In a few cases, a slight contamination with foreign objects such as metal particles makes processing more difficult.

Depending on the production system this may cause unwanted machine downtimes.

The apparent economic advantage thus is quickly lost if the resulting downtimes cannot be avoided.

The most obvious solution of using metal separators resulted in immediate success.

For the inspection and purification of such industrial materials, S+S Separation and Sorting Technology provided metal separators of type GF Primus.

After the installation of the metal separator, production could be continued without machine downtimes.

It is only the use of metal separators that allows an economic processing of granulate mixed with regenerated material or ground material.

The GF Primus metal separator removes metallic contaminations from the pneumatically conveyed regenerated material.

Installed directly in the pneumatic conveyor pipe of the material conveyor for the injection moulding machine, it reliably separates metallic contaminations, even such contaminations that are embedded in a granulate grain.

With the Easy Mount System, the metal separator can be installed in already existing pneumatic conveyor pipes without any problems.

Parts that are in contact with the product are made of stainless steel (1.4301).

The outwardly sealed separating unit prevents any impairment of the function of the material conveyors due to outside air.

Product effects of the bulk material that are caused by moisture, colour pigments, or carbons, are automatically compensated, which guarantees a constant scanning sensitivity.

One advantage of the Quick-Flap System is the minimum loss of good material.

The contaminated material is collected in a collection container and is thus available for detailed analyses.
