Colloidal Silica Manufacture - Electrodialysis Batch acidification has been the standard method for producing silica sol for decades. When acid is added to a sodium silicate solution, the pH decreases, leading to the formation of silica particles. However, this process has a challenge known as the transition zone, which is the period between acid addition and equilibrium. During this time, local pH gradients can result in uncontrolled particle growth or premature gelation. While this issue can be managed for commodity silica grades, it becomes a persistent quality concern for products with tighter specifications. In contrast, the electrodialysis method offers a more controlled approach. In this process, there is no need for acid addition. Instead, sodium ions continuously migrate out of the silicate solution across ion-selective membranes. This gradual and uniform pH shift throughout the cell facilitates particle nucleation under steadier conditions, resulting in a narrower size distribution and more consistent sol characteristics from one production run to the next. From a financial perspective, eliminating mineral acid from the process reduces costs associated with reagent procurement, handling, and effluent neutralisation—considerations that are significant at a production scale. Laxminarayan Technologies specialises in constructing commercial electrodialysis plants for colloidal silica production, tailored to each producer's desired particle size range and output volume. Pilot plants are available for validation before full-scale implementation.

Shell Firing Furnace Built for Lost Wax Casting Applications – Laxminarayan Technologies Most foundry equipment is evaluated based on capacity and price, but shell firing furnaces deserve more thorough examination. The conditions within the firing chamber directly impact casting quality downstream. The image shows a shell firing furnace from Laxminarayan Technologies in Kolhapur. This unit is specifically designed for the burnout and pre-heat stages of investment casting. During these stages, dewaxed ceramic shells must be heated to a high temperature to complete sintering and remove any remaining organic materials. This ensures that the shells arrive at the casting station at the right temperature to handle molten metal without cracking. A cold or improperly fired shell increases risks at every subsequent step. Laxminarayan's furnace design focuses on maintaining consistent temperatures throughout the load. Unlike older furnace models that can create hot and cold zones, leading to uneven treatment of the shells, these units are engineered to deliver uniform temperature profiles throughout the entire firing cycle. Energy efficiency is also a key consideration; the company reports approximately 50% power savings compared to conventional shell processing equipment. Laxminarayan Technologies has been a key player in the investment casting industry since 1986 and is ISO 9001 certified. They provide comprehensive foundry equipment solutions and have commissioned installations around the world, including setups for aerospace turbine component production. Their support extends from initial foundry layout through on-site operator training.
