Omega

Omega has been formulated to deal with the most demanding situations, producing excellent results even at the most extreme temperatures. Omega+ has optimised thermal expansions, permeability and particle size distribution to enable it to produce the highest quality castings and reproduction of Master Models.

Omega+ has the highest content of unmineralised Cristobalite in the GSP range. A grade of Cristobalite is specifically manufactured for Omega+ at our sister company’s calcining and grinding facility, which ensures that the exact particle size grading required is achieved. Omega+ is suitable for all Yellow and White Golds including High Percentage Palladium White Gold.

Omega+ has been designed for the application of Master Model casting and has been tested with a cross-section of SLA Resins, Carving Waxes and Machined Waxes. Omega+ produces excellent results with smooth surfaces when used to cast with models from companies such as Envisiontec, 3D Systems, Invision and Solid Scape.

The application of Omega+ determines which burnout cycle should be used. If standard Jewellery injection wax is being cast then the burnout cycle below for Injection Wax is to be utilised. If SLA Resins, Machined Waxes or Carving waxes are being cast the burnout cycle for Master Models on page 10 is to be utilised in order to achieve optimum results.
