Plastic has become an important part of everyday life. In order to guarantee high-quality workmanship, finishing or coloring, plasticizing screws must meet high requirements for profile and lead precision. Leistritz has many years of experience in this field. We offer the ideal machine tools for the manufacture of screws, whether high-strength or powder steel is being processed. The integrated CAM software guarantees a high level of user friendliness. Another advantage is that even complex profiles can be processed with standardized inserts from our flexible tool system.
