Sand Casting

Sand casting is a versatile process where a mixture of sand, clay, and water is compacted to form each mold half. The term "greensand" means that the sand binder is not activated by heating or chemical reactions.

In our greensand foundry, we can mold either low or high volume jobs using any of the following methods:

  • Squeezer: Optimal for small to medium parts with moderate complexity
  • Cope & Drag: Ideal for larger castings with complex geometries
  • Floor Molding: Used for very large or specialized components
  • Hunter Automatic Molding: High-volume production with consistent quality

The Sand Casting Process

1

Pattern Preparation

A pattern is created using materials like wood or metal that will form the exterior shape of the part.

2

Mold Creation

The pattern is packed with greensand in a flask consisting of a bottom (drag) and top (bottom) to create the mold.

3

Core Setting

If internal cavities are needed, sand cores are placed in the mold to form these spaces.

4

Pouring

Molten aluminum is poured into the mold through a gating system, filling the cavity created by the pattern.

5

Cooling & Solidification

The metal cools and solidifies into the desired shape within the mold.

6

Shake-out & Cleaning

The casting is removed from the sand, and excess material is trimmed away.

Key Benefits

  • Excellent for complex geometries and large parts
  • Cost-effective for both prototype and production runs
  • Shorter lead times compared to other casting methods
  • Ability to cast a wide range of sizes from ounces to hundreds of pounds
  • Suitable for aluminum alloys with various mechanical properties

Permanent Mold Casting

Our tilt-pour permanent mold process utilizes cast iron molds, machined to exacting tolerances. This helps to achieve near net shape, reducing the need for additional machining and providing excellent surface finish and dimensional accuracy.

We currently house 25 permanent mold machines which cast in sizes ranging from 0.5 lbs up to 57 lbs, and from 3" to 3' long, offering versatility for a wide range of component types.

The Permanent Mold Process

1

Mold Preparation

The cast iron molds are precision-machined, assembled, and treated with a refractory coating (die wash) to prevent sticking and extend mold life.

2

Preheating

Molds are heated to an optimal temperature to ensure proper metal flow and prevent premature solidification.

3

Core Setting

If internal features are required, sand or metal cores are positioned within the mold.

4

Pouring

Using a tilt-pour mechanism, molten aluminum is gradually introduced into the mold cavity, ensuring smooth, controlled filling and reducing turbulence.

5

Solidification

The aluminum solidifies rapidly against the metal mold, creating a fine grain structure with excellent mechanical properties.

6

Ejection & Finishing

The solidified casting is ejected from the mold, and gates and risers are removed through sawing, trimming, or machining operations.

Key Benefits

  • Superior surface finish compared to sand casting
  • Tighter dimensional tolerances and consistency
  • Excellent mechanical properties due to rapid cooling
  • Higher production rates for medium to high volume runs
  • Reduced need for extensive machining operations
  • Better material yield with less waste
  • Good repeatability from part to part

Precision Surface Finish Dimensional Stability Repeatability High Strength

Sand Cores

Some castings require no sand cores while some require several - it depends on the empty space needed in the casting. At PPF, we make all our Shell Cores and No Bake Cores in-house, and work with you during the design process to ensure that empty space is handled effectively and efficiently.

Our in-house core production capabilities give us complete control over quality, delivery times, and customization, allowing us to respond quickly to your changing requirements.

Shell Cores

Shell cores are created using a mixture of sand and thermosetting resin that is heated to form a hard "shell" with excellent strength and dimensional stability. These cores are ideal for:

  • Intricate internal geometries
  • High-production applications
  • Components requiring precise internal dimensions
  • Applications where smooth internal surfaces are critical

No Bake Cores

No Bake cores use a chemical binder system that cures at room temperature. These cores provide:

  • Excellent dimensional accuracy
  • Good surface finish
  • Flexibility for design changes
  • Lower tooling costs for limited production runs
  • Better collapsibility during casting solidification

Core Production Process

1

Core Box Preparation

A precision-manufactured core box is created to form the desired core shape.

2

Sand Mixing

Sand is mixed with the appropriate binding system - either thermosetting resin for shell cores or chemical binders for no-bake cores.

3

Core Formation

The prepared sand mixture is introduced into the core box and formed through either heat application (shell) or chemical reaction (no-bake).

4

Curing & Finishing

Cores are properly cured, and any excess material is removed to ensure dimensional accuracy.

5

Quality Checking

Each core is inspected for defects, dimensions, and hardness to ensure it will perform correctly during casting.

Sand Cores

Core Design Considerations

Effective core design is critical to successful casting. Our experienced engineers work with you to optimize cores for:

  • Core Strength: Ensuring cores withstand the pressure of molten aluminum without breaking
  • Gas Generation: Minimizing gas-related defects during casting
  • Collapsibility: Allowing for proper breakdown during casting solidification and cooling
  • Core Prints: Designing proper support features to maintain core position during casting
  • Venting: Incorporating appropriate venting to release gases during casting
