Single screw and barrel are widely used in plastic industries. It can be used to process wide range of polymers.
Extrusion Screws Designed for Optimal Performance and Extended Life. We guide our customers on optimizing processes, avoiding costly repairs, and extending the life of valuable components. Recognizing that general-purpose parts often fall short of meeting the demands of ever-changing technology, our decades of experience in extrusion screw design enable us to address every aspect of plastics. From compounding to blown film, we specialize in producing screws for premium color mixes, ensuring the most efficient compounding and throughput.
Carefully engineered screw geometry to match the exact needs of your process; high throughput, supreme mix, and melt quality for optimum component life; quality inspections at every step of the process to create customized parts specific to our customers’ demands;
On-site Consulting and Field Services. Our extrusion screws empower you to maximize extrusion throughput, product quality, and component service life. We can provide a variety of screws for extrusion, including 3-zone screws, multiple thread screws, barrier screws, vented screws, or highly complex twin screws.
Screws are available in sizes ranging from 14mm to 300mm with a maximum length of 5000mm. We also offer customized solutions based on the specific requirements of our invaluable clients. Through a strict quality test at every stage of production, we ensure that every single screw is flawless.

Here’s a version of your text with justified alignment:
Chrome plating and ion nitriding are the most common screw surface treatments. TiN coating and nickel plating are sometimes used but only in special applications. Carbide coating of the flight tops or encapsulation of the entire flighted length can add additional wear protection. The carbide can be applied in different thicknesses and be polished to different RMS.
