Ningbo Yinzhou Hisea Machinery Co.,Ltd.

Water glass casting

Process principle:

1. Sand mixing: Raw sand+water glass → mix evenly.

2. Styling/Core making: Fill the mixed sand into the mold and compact it by hand or machine.

3. Blow hardening: Silica gel precipitates to form a three-dimensional network, strongly bonding sand particles to achieve high strength.

4. Demoulding and shaping: Immediately remove the mold after hardening and repair any damaged areas.

5. Box casting: Assemble sand molds and pour molten metal.

6. Sand removal: Shake the casting to remove sand after cooling.

Advantages:

1. Fast hardening speed and increased efficiency:

CO ₂ blown into shape in seconds, significantly reducing the production cycle.

2. High strength and strong anti-interference ability:

After hardening, it has high strength and is not easily deformed during transportation, reducing the risk of sand flushing and box collapse.

3. Environmentally friendly, green casting pioneer:

-No formaldehyde/phenol toxic gas, better environment than resin sand;

-Old sand is easily regenerated by wet method, with a recovery rate of over 80% and low solid waste emissions.

4. Low cost and outstanding economy:

-The price of water glass is only 1/5-1/3 of that of resin;

-CO ₂ gas is cheap and easy to obtain, with low energy consumption.

5. Wide material adaptability:

-Especially suitable for high-temperature materials that are sensitive to nitrogen and sulfur;

Application areas:

1. Heavy machinery: large machine tool bed, steel rolling frame, mining crusher jaw plate, 10000 ton hydraulic press base

2. Cast steel parts: power station valve body, turbine blades, steel ingot mold, wear-resistant gear plate, slag tank, container corner parts

3. Construction vehicles: excavator counterweights, track shoes, large gearbox bodies

4. Shipbuilding: anchor chain wheels, mooring bollards, thruster brackets

5. Chemical equipment: acid resistant pump casing, reactor lining substrate

6. Rail Transit: Train Hook Tongue, Buffer Shell, Switch Accessories
