Each batch of ingot produced undergoes constant monitoring and testing throughout the production process using the latest emission spectrometry. Before casting, gas contents are reduced with automatic rotary degasser and checked in situ by using Alspek H sensor and by  pin-hole testing equipment. Inclusion levels are determined by K-mould. Our constant commitment to quality and continuous improvement is reinforced by our purchase of the KV counter. This instrument, developed by Nippon Light Metals, accurately quantifies the inclusion levels in the K mould, and is the first instrument of its kind commercially in use outside of replica watches the Toyota Group in Japan.
