Sai Extrumech is a screw and barrel manufacturer in India with 25+ years of engineering, based in Faridabad. We design and manufacture nitrided and bimetallic screws and barrels in-house for any extruder make or model, in custom diameters from 25 to 150 mm and L/D ratios from 20:1 to 33:1, matched to your polymer and output. Machines and tooling installed across India, the UAE, UK, South Africa, Bangladesh, Nepal and Sri Lanka.

Nitrided screws & barrels – economical and reliable for PVC, PE, PP and most unfilled thermoplastics. Case-hardened to around 900–1000 HV, they cover the majority of wire and cable extrusion.
Bimetallic screws & barrels – centrifugally cast alloy liner metallurgically bonded to the bore, reaching ~60–65 HRC. The right choice for abrasive, glass-filled, flame-retardant and HFFR/LSZH compounds, and for XLPE and masterbatch work; typically lasts several times longer than a nitrided assembly on filled grades.

- 25+ years as an extrusion machine manufacturer in India; exports to the UAE, UK, South Africa and more
Screws and barrels are critical components in extrusion processes. They work together to melt, mix, and convey raw materials through the extruder to create the desired product shape.
Screws and barrels are typically made from high-quality, wear-resistant materials such as nitrided or bimetallic alloys. These materials ensure durability and long service life, even under demanding processing conditions.
Yes, we offer customized solutions tailored to meet your specific needs. Whether it’s a unique design, material choice, or specific dimensions, our team can create screws and barrels that enhance your production process.
Selecting the right screw and barrel depends on factors such as the type of material being processed, the desired product characteristics, and the specific requirements of your production process. Our experts at Sai Extrumech can help you choose the best components for optimal performance.
