PRE-CAST PRE-FIRED (PCPF) BLOCKS
Hand Moulding / Precast Shapes
MRPL manufactures all refractory shapes which are difficult and/or impossible to make through Pressing. Products of this kind ranges from non-standard bricks that are too big in size or are of complex and complicated shapes, to where metal anchors or frames are made or where only few pieces are to be made. MRPL has its own mould-making section with separate sections for hand moulding and precast to assure the product quality in terms of shapes, sizes, dimensional accuracy and surface finish. Quality and temperature of the water, required for casting, are monitored and maintained based on the ambient conditions to minimize the seasonal effects. These materials are fired in Kilns as per the process requirement and quality of products. The most important requirement of precast shapes is its quality. It should be almost same as the rest of the refractory structures.
