UFiP use a unique method of production for all of their cast bronze cymbals that they call Rotocasting. This method of centrifugal casting is normally reserved for components such as jet engine parts, military grade items and other critical components where the highest quality is essential. Molten Bronze is poured into a cymbal mould which is spinning at 1000 rpm causing a high G-Force to be applied to the molten metal as it cools. This eliminates gas and air bubbles forming before the Bronze hardens and also causes impurities to float to the top of the cymbal blank. This is then removed in the subsequent stages of manufacture.
The result is a purer metal that will be stronger and much less prone to potential damage in use. Because of this unique technique UFiP are also able to create thicker bells which makes them louder and more ‘bell-like’. This gives UFiP more control of the cymbals resonance creating much more diversity across the ranges, plus additional strength where the bell meets the shoulder. This also eliminates a further potential point of weakness created by the original production method used by other cymbal makers.
