hile the SIKORA PURITY SCANNER inspects online

plastic pellets for contamination and sorts contami-

nated pellets out automatically, the PURITY CONCEPT Sys-

tems are used for on- and offline inspection and analysis

of plastics material. They detect and analyze contamina-

tion from 50µm and assure the highest material quality

and stable production processes.

Online process control:

For monitoring production pro-

cesses the plastics material is tested during raw material

manufacturing on a random basis. The PURITY CONCEPT

Systems inspect material samples directly from the produc-

tion and provide the material producers with valuable in-

formation about their processes.

Incoming goods inspection:

Sophisticated products such

as for example medical tubes require a reliable control and

processing of raw materials. In the different processes of

manufacturing plastic products contamination may occur.

During the transport of material, for example, contamina-

tion can get into the plastic pellets (e.g. at the unloading

of the transport vehicles to the silo caused by dust or other

foreign objects). Commonly, manual samples are done be-

fore the material is further processed. However, the smal-

lest metallic or organic contamination from 50µm are not

visible to the naked eye. There are for example high de-

mands placed on purity in the area of injection molding as

well as the spraying nozzles can get clogged by contami-

nation, which causes high follow up costs. The PURITY

CONCEPT Systems provide an efficient solution for auto-

matic sample inspection at the incoming goods inspection

and ensure that only pure raw material gets into the next

production step and further processing.

Analysis:

Another area of application of the systems is the

analysis of defects or contamination. In combination with

an image processing software the PURITY CONCEPT Sys-

tems analyze and evaluate contaminated material on the

basis of statistical data and thus identify possible sources

for contamination. These information significantly contri-

bute to process optimization.
