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.
