We export across Europe, the Americas, Southeast Asia, and the Middle East, tailoring alloy selection (nitriding, bimetallic, HVOF) and screw geometry to your specific resin, output, and wear conditions.
Four key pillars that set us apart from the competition
We engineer screw profiles that improve output, mixing, and melt quality for your specific processing requirements.
High-grade tool steels (38CrMoAlA, W6Mo5Cr4V2, D2) and certified bimetallic alloys extend barrel life.
Every shipment is inspected for dimensional accuracy, hardness, and coating thickness before delivery.
Semi-finished blanks kept in inventory to shorten delivery, backed by responsive after-sales support.
A reliable screw and barrel are the foundation of your productivity. PIPLL is focused on minimizing your downtime, reducing wear-part costs, and building long-term partnerships through precision-engineered components — not just transactions.
