OEM Sand Casting Service for Cast Iron Metalworking Foundry Galvanized Iron Casting Parts

As a specialized OEM metalworking foundry, we provide comprehensive sand casting solutions for cast iron components with optional galvanization treatment. Our technical expertise in traditional sand casting combined with modern manufacturing capabilities enables us to deliver high-quality, custom-engineered cast iron parts that meet precise OEM specifications and performance requirements across diverse industrial applications.

Material Selection and Performance Characteristics

Our foundry specializes in various grades of cast iron, each offering distinct performance advantages:

Gray Iron Castings:
We produce gray iron components (Grades G25-G35) characterized by excellent vibration damping capacity, good machinability, and outstanding thermal conductivity. The graphite flake structure inherent to gray iron provides natural lubricity and makes it ideal for applications requiring wear resistance.

Ductile Iron Components:
Our ductile iron production (Grades 65-45-12, 80-55-06) offers superior mechanical properties with enhanced tensile strength, impact resistance, and elongation characteristics. The nodular graphite structure provides strength comparable to steel while maintaining good castability.

Galvanized Iron Parts:
We provide hot-dip galvanizing services that apply a protective zinc coating to cast iron components, significantly enhancing corrosion resistance for outdoor applications and harsh environments. The metallurgical bond between zinc and iron creates a durable barrier protection with typical coating thickness of 60-100μm.

Advanced Sand Casting Methodology

Our manufacturing process employs sophisticated sand casting techniques:

Pattern Making:
We create precision patterns from wood, plastic, or metal using CNC machining to ensure dimensional accuracy and proper allowance for shrinkage. Our engineering team optimizes pattern design for efficient molding and casting yield.

Molding Systems:
We utilize both green sand and chemically-bonded sand systems depending on production volume and complexity requirements. Our resin sand casting capabilities particularly suit medium-to-high volume production of complex geometries with superior surface finish.

Pouring and Solidification Control:
Our controlled melting operations in medium-frequency induction furnaces maintain precise chemical composition and pouring temperatures. We implement scientifically-designed gating and risering systems to ensure proper filling and directional solidification, minimizing casting defects.

Secondary Processing Capabilities

Our comprehensive metalworking services include:

• Precision machining of critical surfaces and bore diameters
