Cast Iron Shell Molding Casting Sand Casting Products

Material Specifications and Performance Characteristics
We utilize high-grade gray iron (Grades G2500-G3500) and ductile iron (Grades 40018-70002) selected according to specific mechanical property requirements. Our gray iron castings deliver excellent compressive strength and superior vibration damping capacity, with tensile strengths ranging from 250-350 MPa. Ductile iron components provide enhanced mechanical properties including tensile strength of 400-700 MPa, remarkable impact resistance, and elongation up to 18%. Both materials demonstrate exceptional wear resistance, thermal stability, and reliable performance under heavy load conditions, with shell-molded components exhibiting improved surface density and reduced porosity.

Advanced Manufacturing Processes
Our shell molding process employs resin-coated sand that forms precise, thin-walled molds cured under controlled temperature conditions. This method produces castings with smoother surface finishes (125-250 Ra), tighter dimensional tolerances (±0.005 inches per inch), and reduced machining allowances compared to conventional sand casting. Our complementary green sand casting operations utilize automated molding lines for cost-effective production of larger components. Both processes incorporate advanced pouring systems with real-time thermal monitoring to ensure optimal solidification patterns. Post-casting, components undergo precision machining on CNC equipment, with critical features finished to tolerances within ±0.001 inches.

Comprehensive Industrial Applications
Our cast iron shell molded and sand cast products serve vital functions across numerous sectors. The automotive industry utilizes our components for brake discs, engine blocks, and transmission cases. In fluid handling applications, we produce pump housings, valve bodies, and compressor parts requiring pressure integrity. The construction equipment sector relies on our castings for machinery bases, hydraulic components, and structural supports. Additional applications include agricultural implements, power transmission components, and heavy machinery parts where durability, wear resistance, and structural integrity are essential performance requirements.
