Any high-quality casting begins with a high-quality mould. This concept is clearly embodied in our investments in technology for producing moulds which result in castings with exceptional dimensional accuracy & superior surface finish.

The sand used in the moulds is a key ingredient in producing a high-quality mould. State of the art equipment such as Disa PS Polygonal Sieves, Sand Coolers from DISA and Intensive Sand Mixers from DISA are used for ensuring a high level of quality in the output sand.
