Automation
and materials flow for
a polysillicon factory.

The task

Conveying
Storage
Handling

A factory for the production of high-purity polysilicon for the solar industry was planned in the Middle East. In order to ensure the highest quality despite the lack of local specialists, this factory was planned to be predominately automated. Until now, the processing in other factories worldwide has been mainly manual, so Alztec will be introducing new developments and concepts in many areas.

The solution

Alztec finds unique techniques for the automated processing of polysilicon that meet the highest purity requirements for the solar sector. In addition, a complete material management system with batch tracking is supplied.

The entire factory is equipped with Alztec systems, from harvesting the silicon from the CVD reactor to final packaging of the polysilicon ready for sale.

Various processing steps with transport and storage of the silicon rods as well as crushing, sorting, transport and storage of the silicon chunks are implemented.

Alztec also perfectly mastered the challenge of international coordination of the project with a wide variety of requirements such as customs clearance, work permits, cooperation with local companies and authorities, etc.
