This industrial backbone is engineered for uninterrupted, high-intensity production. Understanding that downtime means loss, we reject compromise at every critical durability component. The extruder's core—screw and barrel—is crafted from 38CrMoAlA alloy steel with deep nitriding treatment, achieving surface hardness up to HV1000 to withstand years of wear from PP fillers. The gearbox features integrally cast HT250 iron, annealed to relieve internal stress, with internal helical gears hardened and precision-ground for smooth, quiet operation. From the robust welded frame to brand-name bearings and seals, every detail reflects our commitment to reliability, delivering decades of stable service.

It is crucial, especially for PP materials that may contain fillers like calcium carbonate. Nitriding is a surface chemical heat treatment that forms an extremely hard (above HV1000) and corrosion-resistant nitride layer on the steel surface. This "armor" effectively resists abrasive wear from the plastic melt, particularly fillers. Ordinary carbon steel or untreated alloy steel may suffer severe wear within months when processing abrasive materials, leading to decreased output, uneven plasticization, and increased energy consumption. Our nitriding treatment depth can reach 0.4-0.6mm, ensuring performance is maintained even after long-term wear.
The overall machine design life exceeds 10 years, with core structural components lasting over 15 years. Daily maintenance is key to ensuring longevity:
Our provided maintenance manual will guide you through these tasks in detail.
