Casting chamber under full vacuum with appropriate inert gas protection (argon or nitrogen). Vacuum removes gases from the invested flask minimizing or eliminating gas porosity and radically enhances crucible life, argon or nitrogen gas prevents oxidation of gold and platinum alloys.
Medium-frequency induction melting with self-stirring effect to ensure absolute homogeneity from the top to the bottom of the cast tree.
Fusus New HD incorporates the system features and the latest process control technology for high-production casting of both platinum and gold with extremely fast cycle times (just abt 60 seconds for platinum and 3 minutes for gold).
Fully automatic and semiautomatic cycles. In the automatic cycle, operator sets new casting parameters or choose a program stored in memory, then push one button to initiate the complete casting cycle. In the semi-automatic cycle, when temperature reaches the set point, operator can watch the melt and push the casting button to start the centrifugal arm when the metal is considered ready.
All casting parameters are programmable and can be stored in memory, including precise controlled metal temperature, r.p.m. of the centrifugal arm, acceleration, vacuum and gas pressure.
All functions are controlled by a full-color touch-screen computer mounted on an articulated box that can be easily positioned for the operator convenience.
Two temperature control systems: immersion thermocouple for gold up to 1,150°C (2,100 °F) and infrared optical pyrometer for platinum up to 2,100 °C (3,800 °F) ± 2%.
Optional state-of-the-art Land Instruments Dual-Color Optical Controller available for maximum temperature accuracy of platinum up to 2,100°C (3,800 °F) ± 1%. This fiber-optic pyrometer is designed for precise platinum temperature measurement.Highly recommended for use with automatic cycle for platinum. Must be ordered with the machine, impossible to retrofit it.
Available with choice of 60- or 100-cubic meter vacuum pump (optional). Includes crucible kit (please specify gold or platinum) and flask cradle (please specify flask size).Includes installation and operator training.
