Top quality jewelry investment powder

Yoshida Cast is a pioneer of platinum
investment powder for fine jewelry manufacturing

In 1963, Yoshida Cast developed and launched Japan's first centrifugal casting machine for platinum using induction heating technology. At the same time, Yoshida Cast began sales of jewelry investment powders for high-melting-temperature alloys such as platinum casting alloys. In 1966, Yoshida Cast introduced a new type jewelry investment powder for platinum casting, which was improved from a conventional self-coagulation method to the non-self-coagulation/dehydration method.

Similar but different grain shapes

Typical silica type investment powder for platinum alloys have angular grains because the solids are milled to a particle size.
On the other hand, ALL investment powder is rounded without individual protrusions, resulting in a casting surface of a higher rank.
Needless to say, production is carried out by wet agitation and computer-controlled quantitative agitation, and each production lot is monitored for particle size distribution under strict particle size control to prevent "lot collapse," so we can provide stable quality at any time.
