Ceramic Shell Building:
Tanks Designed for Shell Dipping
In the investment casting process, slurry mixing technology is essential for achieving consistent ceramic shell quality and structural integrity of the ceramic shell of wax moulds in lost wax castings. At VA Technology, we supply a full portfolio of mixing solutions, including small to large capacity mixer tank units and slurry transfer pumps to fully automated mixing system configurations.
Slurry Tanks
Our slurry tanks are purpose-built to deliver reliable, efficient and uniform slurry mixing. We manufacture both HD and DD series tanks to support a wide range of shellroom layouts and production volumes.
HD Slurry Tanks
- Stainless steel construction with mild steel support frame
- Water‑cooled mix blades for precise temperature control
- Fixed mixing paddle with rotating tank for optimal slurry circulation
DD Slurry Tanks
- Direct on‑line starter and isolator control
- Variable‑speed drive for accurate mixing control
Slurry Mixing & Dosing Systems
We can manufacture and install integrated slurry transfer pumps to maintain continuous flow, while automated dosing systems replenish the tank with precise volumes of liquid material. These combined mixing solutions give foundries greater control over shell‑building conditions and production efficiency.
Control & Monitoring Systems
To maintain optimal slurry conditions, our shellroom systems incorporate advanced monitoring technologies, including:
- Laser level systems for accurate slurry tank measurement
- Automated viscosity and pH monitoring via high‑precision viscometers and pH meters
Why choose VA Technology?
Our shellroom solutions offer a full range of tanks to support every stage of the process:
- Etch, wash, and rinse tanks for pattern cleaning, with optional spray nozzles for liquid and air
- Pre‑wet tanks
- Blow‑off tanks for removing loose stucco
We have extensive experience in designing, manufacturing, installing and servicing shellroom systems for the investment casting industry. We manufacture equipment, from design engineering and fabrication through to equipment assembly, test & validation, and commissioning. VA Technology provides complete support & service for your shellroom operations, including onsite and remote technical support and training programmes to ensure you have ongoing, long‑term support.
Our product range includes IC-Robots, rapid drying systems, slurry preparation systems, dust collection systems, environmental control systems, slurry pumping systems, integrated shell management systems, and more. Contact us for more information.
