Custom CNC Turning and Shell Molding GGG50 Ductile Cast Iron Casting Services

As a specialized manufacturer in precision metal components, we provide integrated CNC turning and shell molding services utilizing GGG50 ductile cast iron. Our comprehensive manufacturing approach combines advanced casting technology with precision machining to deliver components that meet the most demanding specifications for strength, durability, and dimensional accuracy across various industrial applications.

Material Excellence: GGG50 Ductile Iron Properties

GGG50 ductile iron (also classified as 450-10 per international standards) offers an exceptional combination of mechanical properties that make it ideal for high-stress applications. The material demonstrates minimum tensile strength of 450 MPa, yield strength of 310 MPa, and elongation of 10% in standardized testing. The nodular graphite structure within the ferritic-pearlitic matrix provides:

• Superior impact resistance compared to standard cast irons

• Excellent fatigue strength for cyclic loading applications

• Enhanced wear resistance for moving components

• Good machinability with proper tool selection

• Reliable performance across temperature variations

Advanced Shell Molding Manufacturing Process

Our shell molding technology delivers precision castings with exceptional surface quality and dimensional stability:

Pattern and Mold Engineering
We design and manufacture metal patterns with precise shrinkage allowances, incorporating:

• Strategic gating systems for optimal metal flow

• Proper draft angles for easy pattern extraction

• Venting systems to minimize gas entrapment

• Uniform wall thickness considerations

Shell Mold Production
The resin-coated sand process creates robust molds featuring:

• Excellent surface finish quality (Ra 3.2-6.3 μm)

• Tight dimensional tolerances (±0.13mm per 25mm)

• Consistent mold density and strength

• Minimal binder usage for reduced gas generation

Precision CNC Turning Integration

Our comprehensive machining capabilities complement the casting process:

• Precision turning of critical diameters and faces

• Boring operations for accurate internal geometries

• Thread cutting for assembly components
