Sintering is the optimum process for producing
multi-coloured rings, mostly sold as
wedding rings. Metals are processed under
pressure and at temperatures below the solidification
point. The pressure is generated
pneumatically and not mechanically via a
threaded spindle. This means that there is no
risk of graphite parts breaking as a result of
heat expansion. The fusion between layers
has the same durability as the metal itself.
Pre-manufactured rings can be easily resized
(7 sizes and more).
