Our Green Sand Casting Process

TigerHubs supports custom green sand casting through a coordinated molding and pouring process. From pattern preparation and sand molding to metal solidification and casting cleaning, each stage helps produce metal components with consistent geometry and manufacturing quality.

Pattern Preparation

Pattern Preparation

Prepare the casting pattern with appropriate shrinkage allowance, draft, and parting features to define the mold cavity and support repeatable molding.

Green Sand Preparation

Green Sand Preparation

Mix and condition molding sand with clay and controlled moisture to achieve suitable compactability, strength, and mold-forming properties.

Mold & Core Assembly

Mold & Core Assembly

Compact prepared sand around the pattern, remove the pattern, and position required sand cores before assembling the cope and drag.

Molten Metal Pouring

Molten Metal Pouring

Pour molten metal into the assembled mold through the designed gating system, allowing the cavity to fill before solidification begins.

Cooling & Shakeout

Cooling & Shakeout

Allow the casting to solidify and cool sufficiently before separating it from the sand mold using an appropriate shakeout process.

Casting Cleaning & Fettling

Casting Cleaning & Fettling

Remove gates, risers, and residual molding sand to prepare cast components for subsequent manufacturing operations or delivery requirements.

Green Sand vs. Resin Sand Casting

Green sand and resin sand casting offer different molding advantages. Green sand is often efficient for repeat production, while resin-bonded sand can provide greater mold rigidity for selected large or complex castings. Compare both processes to choose a suitable solution for your project.

Frequently Asked Questions

Learn More
What is green sand casting?

Green sand casting forms molds using sand bonded with clay and water. The molds retain moisture during the molding process and are used to produce metal castings.

Is green sand casting environmentally friendly?

Green sand can be reclaimed and reused within a managed foundry sand system. However, environmental performance depends on energy use, emissions, material handling, and waste management. The term “green” does not mean zero environmental impact.

Is green sand casting suitable for iron castings?

Yes. Green sand molding is widely used for gray iron and ductile iron castings, subject to foundry capability and component requirements.

Can green sand casting produce hollow components?

Yes. Suitable sand cores can form internal cavities and passages, with feasibility depending on core design, support, and casting geometry.

What determines green sand casting cost?

Tooling, alloy, casting weight, geometry, core complexity, order quantity, yield, secondary machining, and inspection requirements can all affect cost.

Can green sand castings be CNC machined?

Yes. Critical faces, bores, and mounting interfaces can be machined when appropriate stock and part geometry have been provided.

Is green sand casting suitable for low-volume orders?

It can be, depending on tooling costs, molding method, casting complexity, and foundry economics. Some projects may be better suited to other sand casting methods.

What files are required for a green sand casting quote?

A 3D CAD model and 2D drawing are recommended, along with alloy grade, estimated quantity, required dimensions, machining requirements, and any applicable quality standards.
