Robust Slurry Systems for Shell Dipping

In the investment casting process, slurry mixing technology plays a vital role in ensuring ceramic shell integrity, consistency, and production efficiency. At VA Technology, we offer a comprehensive range of slurry handling solutions. This includes slurry tanks and slurry transfer pumps to fully integrated automated shell coating systems designed to meet the demands of investment casting foundries.

Slurry Tanks: Engineered for Performance

Our slurry tanks are built for reliable, efficient, and consistent mixing of ceramic slurry. We manufacture HD slurry tanks for high-volume operations and DD slurry tanks for compact shellrooms.

HD Slurry Tanks

• Constructed from stainless steel with mild steel support
• Standard sizes: 600mm-1600mm (24”-63”) diameter; 600mm-1300mm (24”-51”) depth
• Water-cooled mix blades for temperature control
• Fixed mixing paddle and rotating tank for optimal slurry mixing

DD Slurry Tanks

• Direct on-line starter and isolator control unit
• Variable speed control for precise mixing
• Standard sizes: 600mm-1200mm (24”-47”) diameter; 600mm-1000mm (24”-39”) depth

HD and DD slurry tanks can be custom manufactured to meet your specific production requirements.

Slurry Mixing & Dosing Systems

Our mechanical engineers have carefully designed the slurry mixing tanks to ensure uniform slurry consistency across all shell layers. We offer integrated slurry transfer pumps that maintain continuous flow, along with slurry dosing systems that automatically replenish the slurry tank with a consistent volume of liquid material. Together, these shellroom solutions provide greater control over the shell-making process, ensuring optimal conditions for maximum production efficiency.

Intelligent Monitoring & Control

To maintain optimal slurry conditions, our shellroom systems include advanced monitoring tools, including:

• Slurry laser level system for accurate tank readings
• Automatic slurry viscosity and pH monitoring using high-precision viscometers/pH meters
• Control panel options for process-integrated automation

Our comprehensive shellroom solutions also include a range of auxiliary tanks designed to support every stage of the shell-making process:

• Etch tank, Wash tank and Rinse tanks for pattern cleaning applications – which can be equipped with spray nozzles for liquid and air
• Pre Wet tanks – where processes dictate
• Blow off tank for loose stucco/sand removal, ahead of next shell coating

Whether you are building a new shellroom or upgrading an existing shell-line, our slurry tank systems are designed to integrate seamlessly with our IC-series robot systems for automation and manual workflows. We offer an array of IC-series robots to suit your applications, based on the Kawasaki, Fanuc, Kuka or ABB robot system with enhanced engineering to withstand the rigours and demands of investment casting.
