Quality controls on our raw materials (silica sand, resin and scrap metal) are carried out the moment they arrive. Dimensional tolerance of the finished product is verified following international smelting standards.
The sand and sand-resin molds are constantly tested through LOI, ADV, Acid Demand, Granulometry, Microscopy, Humidity and Permeability, among others. Melted steel is probed by an optical-emision Spectrometer and its temperature gauged by an Immersion Pyrometer before being poured into the molds.
With the casted pieces, we perform non-destructive and destructive physical analysis. The former with liquid penetrant, magnetic particles, hardness and spectrometric analysis. The latter through traction and impact testing and a complete metallographic laboratory, microphotography included.
