As an experienced grey iron foundry, we provide complete grey iron casting services to meet diverse customer demands. Our custom grey iron casting solutions follow strict international standards to ensure consistency and reliability in every batch.
We specialize in producing grey iron castings that comply with EN 1561 EN‑GJL specifications. Our main material grades include GG20, GG25, GG30 casting, which are suitable for machinery bases, pump bodies, valve parts, automotive components and other structural parts. Each grade is selected based on mechanical properties and application requirements.
Our Professional Grey Iron Castings Process
Our grey iron casting production combines mature sand casting technology with modern quality control. From mold making and melting to pouring, shakeout and finishing, every step is monitored to ensure dimensional accuracy and internal quality.
We use advanced testing methods to check material composition, hardness and mechanical properties. This ensures all GG20, GG25, GG30 casting products fully meet EN 1561 EN‑GJL standards and customer technical requirements.
Custom Grey Iron Castings Solutions
Our custom grey iron casting supports flexible order quantities from prototype to mass production. Our engineering team assists with product design optimization to improve casting formability and reduce production costs.
As a professional grey iron foundry, we offer one-stop services including casting, machining, heat treatment and surface finishing. We are committed to providing high-quality grey iron casting services with on-time delivery and competitive pricing.
