The production chain of a product starts by charting out the customer’s needs, after which the product is designed using 3D technology.

Our developed production processes enable precision-machined solutions, and our manufacturing methods guarantee straight screws and thus operation without vibration. All screw conveyors are tested and test reports are compiled. Test reports are created and stored for all products.

The manufacturing materials used are carbon steels of various qualities, stainless and acid-resistant steel, and most types of special alloy steel. The steel qualities used include: S335, Hardox 400, EN-1.4307, EN-1.4404, EN-1.4462, EN-1.4162, EN-1.4410, EN-1.4571, SMO254.

Our screw conveyors are based on standard modules, which enables us to meet the customers’ needs quickly and efficiently. This makes the production of custom-ordered works quicker, shortens the delivery times and increases cost-efficiency. Through durable and reliable products, we offer a long service life and low operation and maintenance costs. We also manufacture conveyors for ATEX classes 21 and 22.
