Fluidised Bed Stucco Applicator – Uniform Shell Coating Machine | Laxminarayan Technologies

At Laxminarayan Technologies, our Fluidised Bed Stucco Applicator is engineered to deliver consistent, uniform, and efficient stucco coating for investment casting shell building. This advanced machine is specially designed for applying backup stucco layers using a fluidised bed of refractory particles, providing superior shell thickness control, minimal wastage, and enhanced shell permeability. Key Features & Capabilities Uniform coating via fluidisation: Air is used to fluidise the stucco particles, allowing them to behave like a liquid and envelop the shell uniformly, even around complex geometries. Dual bed or multi-bed design: Some models include two or more fluidised beds to increase throughput and flexibility in stucco layering. Exporters India Controlled air distribution and baffles: Specially designed nozzles ensure even air flow and steady fluidisation, while baffles regulate airflow in both the main bed and dust exhaust line. Exporters India Dust extraction & collection ports: Equipped with dedicated dust collection outlets to manage nuisance dust and maintain a clean working environment. Exporters India Drain port & safety design: A drain port may be included to allow safe discharge of fluidised sand when needed. Exporters India Applications & Benefits Ideal for backup stucco application using coarser mesh sizes (e.g. –16 +30, –30 +40, –60 +80) to build shell strength and permeability. Exporters India Enables rapid shell build-up while minimizing wastage and ensuring consistency. Enhances shell permeability and gas escape during metal casting, reducing casting defects. Reduces manual labor, improves repeatability, and ensures better yield on complex investment casting patterns. Cleaner process with dust control features—critical in modern foundries. Why Laxminarayan Technologies? Decades of specialization in foundry machinery and shellroom equipment.
