One and only solution reached by our search for better quality mold Aeration Sand Filling
Aeration sand filling makes mold difference.
“Good Castings Rely On Good Molds.” is
the common saying among professional foundry men
worldwide since quite a long time ago.
This statement carries profound meaning today because
the requirements for quality cast products are becoming
more and more stringent.
A mold's dimensions, hardness and strength are critical
for the production of high quality castings.
To address this need Sinto has developed a Uniform
Mold Sand Filling Method, one of the key elements in the
mass production of superior quality molds.
Under this circumstance, we, Sinto adhered to
Uniform Mold Sand Filling as one of the basic for the
mass production of superior quality molds.
This concept has been manifested through the
Aeration Sand Filling System.
Low pressure air fluidizes the green sand in the tank and
delivers it smoothly and uniformly to every cavity and
corner of the pattern.
A new molding machine series has been developed by
combining aeration sand filling, with the most advanced
molding technology.
“Good Castings Rely On Good Molds.”
Aeration Sand Filling □Advantages created by aeration sand filling (Example of molding)
Aeration sand filling, is performed with
much lower pressure than that used
for blow system machines. Air is blown
through the side walls of sand tank to
fluidize the molding sand as well as to
uniformly pressurize the sand tank.

●Uniform sand filling density●Uniform sand filling is possible even for intricate and complicated cavities. Sand can flow around corners with little or no shadowing effect. ●Air consumption is reduced by 70% compared to blow system. (Data obtained by comparison with our conventional machines)●Noise level is as low as 75dB(A) eq.
