Vacuum casting machine features ultra-fast casting speed and simple maintenance


May 29, 2004 -- Vacuum casting machines for the lost-wax casting of metal alloy are today widely used in fields like rapid prototyping, jewellery, protesys and dental application, aircraft engine parts.

Following suggestions from real users, Topcast Engineering™ TVC vacuum casting machine offers new features for a wide range of metal alloys. Alloys based on gold, silver, brass, bronze, aluminium, tin and other metals can be melt.

Melting and casting can be made under vacuum or inert atmosphere.

Pressure may be differentiated between the melting chamber and the flask chamber up to 3 bar. Maximum process repeatability is ensured by adoption of ceramic sealing materials.

Elimination of materials like cement, plasters, pastes, glues carries to a very simple and fast maintenance.

Other features:

Ultra fast speed: less than 3 minutes for a complete melting/casting cycle of 2kg gold alloy.

Simple and cheap graphite crucible. It can be changed in less than 1 minute.

Fully programmable: 100 user programs for setting temperatures, pressure / vacuum level, timings, power rate.

Low inert gas consumption: 20 liters per melting/casting cycle.

Various sizes are available, depending on the application, with crucible capacity starting from 0,1 liter up to 4,5 liters and power ratings from 5 to 30 kW.
