In this method, the ceramic slip is poured into a closed mold, and pressure is applied to force the slip into the intricate details of the mold. This allows for more complex shapes and finer details to be achieved.
Drying :After forming, the partially solidified sanitaryware item needs to be dried to remove excess moisture. This is typically done in a controlled environment to prevent cracking or warping. The drying process may involve natural drying, air drying, or the use of drying chambers.
Finishing :Once the item is completely dry, it undergoes several finishing processes
Trimming :Excess material or rough edges are trimmed off using cutting tools or machines to achieve the final shape and dimensions.
Smoothing :The surfaces of the sanitaryware item are smoothed using abrasives or sandpapers to remove any imperfections and create a uniform finish.
Glazing :Glazing is the process of applying a liquid glass coating to the surface of the sanitaryware item. This not only provides an attractive appearance but also adds a protective layer and makes the item easier to clean.
Firing :After glazing, the sanitaryware item is fired in a kiln at high temperatures. The firing process vitrifies the clay and glaze, transforming them into a durable and non- porous material. The specific firing temperature and duration depend on the type of clay and glaze used.
Quality Control :Once the firing is complete, the sanitaryware items are inspected for any defects, such as cracks, glaze imperfections, or dimensional inaccuracies. Defective items are discarded, while acceptable ones move on to the final stages.
Additional Processes :Depending on the design and functionality of the sanitaryware item, additional processes may be involved, such as attaching flushing mechanisms, fittings, or accessories.
