Hydraulic Functions for Easy Operation of Industrial Aluminum Melting Furnace
1. Pneumatic metering furnace
WDL Pneumatic Holding Furnace is the holding and dosing system for the clear
and closed liquid aluminum,and is applied to aluminum.WDL Pneumatic Holding
Furnace, ranging from 500KG to 4100KG, is applied to all kinds of different types
of diecasting machine and the dosing, ranging from 0.5KG to 100KG, can meet
almost all types of casting parts. The furnace adopts the most advanced control
system of Siemens and is able to improve product quantity and quality due to the
outstanding features of safe reliability, easy installation, simple operation and
efficient dosing speed.
2. Features
- Chamber whole body casting
- Holding bath closed seal
- Silicon Carbide Rod Radiation Heating

4. Operation principle of Aluminum alloy dosing & holding furnace
HPD pneumatic dosing furnace is designed to take metal below the surface of the metal liquid
in the bath, which can avoid completely the oxidization slug and tremendously imp rove the
quality of the alloy liquid. HPD pneumatic dosing furnace is designed to feed directly and
automatically to the diecasting machine or gravity mold free of any contamination.In order
to feed the alloy liquid, overpressure is formed inside the furnace chamber .The level of
alloy liquid inside the rising tube is raised first until the alloy liquid is about to overflow.
When the diecasting machine request the alloy liquid, the pressure inside the furnace
chamber will be increased further in order for the alloy liquid to flow out. The pressure
will be decreased to end the dosing once preset amount being reached.After dosing
completed, the liquid level is raised back to the feeding level for the next dosing.
