Extruder Screws & Barrels

50 Years Of Screw Design & Processing Experience

The correct screw design and specification lies at the core of successful polymer processing.

Materials, blends, masterbatches and additives process under different conditions.

It is therefore essential to have the correct screw design to ensure the melt is stable, without sheer or deterioration.

The processing conditions must be right for the material you are extruding and therefore the screw design has to be specific.

Boston Matthews has over 50 years polymer processing and screw design experience and has developed new screw designs to meet the demands of an always evolving plastic industry.
