Engineered for WAM and EUROLON concrete mixers, this high-strength scraper is designed to tackle extreme abrasion and material adhesion in demanding mixing environments. Manufactured through ISO 9001-certified processes, each scraper is precision-cast using advanced lost-foam casting (EPC) and vertical flaskless molding technology, achieving a material density of 99.8%. This eliminates micro-porosity and ensures structural integrity under heavy cyclic loads, extending service life by over 50% compared to conventional scrapers. The scraper’s specialized geometry, optimized through computational fluid dynamics (CFD), reduces energy consumption by 18% and minimizes material buildup by 62%, ensuring consistent mixing efficiency and lower operational costs.
Crafted from a proprietary high-chromium alloy with 28-32% chromium content and enhanced with molybdenum and vanadium additives, the scraper delivers a uniform carbide network with a hardness of 58-64 HRC. Independent tests verify a tensile strength of 470 N/mm² and impact toughness of ≥8.0 J/cm², enabling reliable performance under high-impact conditions. The metallographic structure, comprising M7C3 carbides in a tempered martensitic matrix, resists deformation and cracking, while the CNC-machined tolerance of ±0.15mm guarantees seamless compatibility with WAM/EUROLON mixers. Backed by digital lifecycle management and 40+ years of technical expertise, this scraper offers a cost-effective solution for reducing downtime and enhancing productivity in concrete production.
