ALUPUS (supplier of molten metal) A supplier of molten metal by turning on a faucet This product needs no fork lift truck or special pomp for carrying and supplying molten metal.
Molten metal is exposed to only its surface, so you can raise the quality of molten metal as possible.
Patent No. 5237752
Electric energy consumption: 0.6kW/m
Length: max. 7500mm
Length of one unite: 1000mm
Speed of carrying molten metal: 117l/min(If size of pipe is Φ50mm and distance from metal's surface is 5cm)
In emergency: returning molten metal in "ALPS" to furnace by opening to the air

Vacuum furnace

Products Description Advantage Statistical Data
CAVAC (removing wax and sintering vacuum furnace with direct-exhaust system) A furnace for heat treatment of cemented carbide, metals, fine ceramics, composite materials and active refractory materials It is useful for heat treatment of many kinds of materials and energy saving.
Its direct-exhaust system enables tight box-less treatment and cleaner atmosphere in a chamber.
The upper part of chamber moves up and down.
It needs no cooling fan.
Patent No. 5265475
