Ceramic Shell & Core Removal

The Right Way. The Waterjet Way.

Waterjet Blasting for Ceramic Shell & Core Removal

High pressure waterjet blasting is the ideal solution for ceramic shell and core removal on investment, lost wax, or plaster casting for any material. Waterjet provides a clean, safe, and repeatable process for aluminum, steel, titanium, and superalloys.

The Aquarese shell and core removal system is fully automated and removes 99% or more of the shell in a single operation – eliminating chemical leaching, manual waterblast, and bead blasting.

High pressure water can be tuned to perform shell knock-out and core removal in a single operation while preserving fragile features on thin walls or sharp edges leaving the base material undamaged. The result is a process that eliminates chemicals and toxic waste, while significantly improving your overall productivity.

Replaces Several Processes, with One

One single process removes both the shell and the core.

Eco-Friendly Process

Improves working conditions. No hazardous operations such as chemical leaching or manual cleaning. Reduced noise levels.

Preserves Part Geometry

Preserve delicate parts with thin walls and/or sharp edges

Highly Repeatable Performance

Optimal & proven process parameters with robotized waterjet. Consistent, quality performance.

Maximize Productivity & Efficiency

Our productive solutions require less manpower than traditional shell and core removal processes.

Aquarese offers several Core Shell Removal (CSR) models to accommodate for high-volume, high-mix, and extra-large castings.


We can solve cluster cut-off operations by combining CSR automation and our Waterjet Machining (WJM) system for a fully integrated solution with unmatched productivity, quality, and flexibility.

A single process to remove ceramic shells or cores from investment casting foundry using Automated High-Pressure Waterjet systems.

Shell removal for foundries

In the investment casting process, or lost-wax, a shell is created to provide a mold for the parts. After the molten metal is poured into the cast and the metal is solidified, the shell must be removed.

Automated High-Pressure Waterjet is a highly effective process that provides a safe, repeatable method to remove shell:

  • Highly productivity: the automated system removes 99.9% or more of shell eliminating the need for chemical leaching and provides highly repeatable results.
  • No damage to the part: does not bend thin walls or smoothen sharp edges.
  • Improves operator safety: no hazardous manual operation, reduced noise level. Hands off the parts.
Core removal for foundries

As part of the investment casting shell process many inner cavities are filled with shell creating a core.  Cores are difficult to remove and often require long & polluting chemical leaching process and/or hazardous manual operations.

Automated High-Pressure Waterjet is highly applicable to core removal and brings the following benefits:

  • High productivity: with precisely directed rotating waterjet, eliminating or greatly reducing the need for chemical leaching.
  • No damage to the part: does not alter the inner surface finish and geometry.
  • Eco-friendly & safe for the operator: using pure waterjet (no chemical), removing manual operation and reducing noise level.
