Ductile Iron Casting

Ductile iron casting is one of our core products. This material offers high strength and excellent toughness. The graphite in ductile iron takes a spherical shape. This structure gives the metal better mechanical properties than gray iron. We produce ductile iron castings for many industries. Our customers use them in automotive suspension systems, steering knuckles, pump housings, valve bodies, and industrial automation parts. We understand that buyers need parts that perform under pressure. Our ductile iron casting delivers that performance.

Our factory operates under strict quality standards. We hold IATF 16949, ISO 9001, ISO 14001, and ISO 45001 certifications. Every batch of ductile iron casting starts with raw material inspection. We check material certificates for all incoming steel. Our team uses a spectrometer to verify chemical composition. This step prevents material defects before production begins. During production, we inspect the first piece of every order. Our HEXAGON CMM and projector check all critical dimensions. Mass production only starts after the first piece passes inspection. Operators check their work every 15 minutes. Quality inspectors do patrol checks every 2 hours. We provide a full dimensional report (FAI) before shipment. Our 6000K standard light source helps us detect surface defects. This ductile iron casting process ensures consistent quality across every batch.

We have built long-term partnerships with global companies like ABB and Cummins. Our on-time delivery rate reaches 98.2%. We accept orders starting from 1 piece. Custom sample development takes 3 to 100 days, depending on complexity. Standard production takes about 30 days. Repeat orders ship in 10 to 15 days. Payment terms are 30% deposit and 70% balance before shipment. Every ductile iron casting has a unique serial number. This number traces back to the production team, operator, and raw material batch. We maintain a quality history file for each customer. This file helps us prevent the same issue from happening twice. Our ductile iron casting comes with a 1-year warranty. If goods arrive damaged, we take responsibility and arrange replacement production.
