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

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

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

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.

Green Sand Casting
- Binder System
- Clay and water-bonded sand
- Mold Strength
- Relies on green strength and compaction
- Production Efficiency
- Well suited to repeat molding with appropriate equipment
- Casting Size
- Limited by molding equipment and flask capacity
- Complex Geometry
- Supports complex features with suitable cores
- Surface & Accuracy
- Depends on molding control, alloy, and casting geometry
- Tooling Economics
- Often competitive for repeat production
- Typical Applications
- Machinery housings, brackets, iron cast components

Resin Sand Casting
- Binder System
- Chemically bonded sand using resin binders
- Mold Strength
- Develops rigidity through binder curing
- Production Efficiency
- Flexible for varied casting sizes and production arrangements
- Casting Size
- Often suitable for selected large or heavy castings
- Complex Geometry
- Rigid molds can benefit certain complex geometries
- Surface & Accuracy
- Depends on sand system, tooling, and process control
- Tooling Economics
- Can suit varied tooling and production requirements
- Typical Applications
- Large housings, equipment bases, complex structural castings
Green Sand Casting Design Guidelines
Design better green sand castings with practical guidelines for wall thickness, draft angles, fillets, parting lines, and core features. TigerHubs helps identify potential molding challenges early to improve castability, reduce defect risks, and avoid unnecessary tooling costs.
| Design Feature | Recommended Design Reference | Engineering Benefit |
|---|---|---|
| External Draft Angle | 1°–3° starting range | Supports pattern withdrawal and reduces mold damage |
| Internal Draft Angle | 2°–5° starting range | Improves pattern release from recessed features |
| Wall Thickness | 4–6 mm preliminary starting range for selected iron castings | Helps reduce thin-section misruns and incomplete filling |
| Fillets & Radii | R3 mm or larger where practical | Reduces sharp transitions and localized stress concentrations |
| Wall Transitions | Use gradual changes between thick and thin sections | Reduces localized hot spots and solidification-related defects |
| Parting Line Design | Prefer simple, accessible parting arrangements | Reduces molding complexity and potential mismatch |
| Core Design | Minimize unnecessary cores and allow secure core positioning | Simplifies mold assembly and reduces core-related risks |

Simplify the Parting Line
Favor straightforward mold separation to reduce pattern complexity, molding difficulty, and unnecessary tooling costs.

Reduce Unnecessary Core Requirements
Simplify internal geometry where possible to reduce core-making operations, assembly work, and potential molding defects.

Minimize Non-Critical Machining
Keep suitable surfaces as-cast and specify machining only where required for fit, function, or assembly.

Frequently Asked Questions
Learn MoreGreen 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.
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.
Yes. Green sand molding is widely used for gray iron and ductile iron castings, subject to foundry capability and component requirements.
Yes. Suitable sand cores can form internal cavities and passages, with feasibility depending on core design, support, and casting geometry.
Tooling, alloy, casting weight, geometry, core complexity, order quantity, yield, secondary machining, and inspection requirements can all affect cost.
Yes. Critical faces, bores, and mounting interfaces can be machined when appropriate stock and part geometry have been provided.
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.
A 3D CAD model and 2D drawing are recommended, along with alloy grade, estimated quantity, required dimensions, machining requirements, and any applicable quality standards.
