Technical features
Technical features and operation rules of device
Polaris Co. products are manufactured based on the latest technologies
and are of the highest qualities. The most recent design and manufacturing
methodologies are employed to increase the lifetime and quality of products.
This product described in the present manual is an electronic centrifuge for
melting metals at high temperatures. The employed technology is providing the
required electrical current via electromagnetic induction.
The alloy to be melted is placed within a crucible and then transferred to the
centrifuge for melting. Due to the centripetal force, the crucible slides towards
the center of the cylinder (The Easy Cast torque arm has full balance with the
cylinder tray and the related cylinders are balanced).
For increased safety, the top lid (cover) is automatically locked during the
operation of the centrifuge and unlocks only at the completion of the centrifuge
operation.
