Gravity casting machine is a mechanical equipment that uses common industrial production of casting parts, and uses the gravity of the earth to cast parts. The gravity casting machine is a machine that pours metal liquid into metal molds under the gravity effect of the earth to obtain casting parts.

The theoretical gravity casting includes sand casting, metal casting, molten casting, lost foam casting, mud forging, etc. The narrow gravity casting refers to metal casting. A gravity casting machine generally refers to a machine that completes the gravity casting of metal molds to open, lock molds, and pick up goods.

There are generally two types of gravity casting machines, tilting gravity die casting machines and stationary gravity casting machines. As one of leading and professional gravity casting manufacturers, we will introduce them to you thoroughly.

What are the features of a tilting gravity die casting machine?

The tilting gravity casting machine can realize the tilting casting of the mold, which can effectively improve the inherent quality of the casting. The action of opening and closing the mold of the tiltable gravity casting machine can be completed in the front and back.

As long as the casting process is controlled by the tilting cylinder, the control of the whole machine is controlled by PLC, and the impact force of the machine is controlled by the electromagnetic flow valve to control the impact speed.

The inclined pouring of our tilting gravity die casting machines enables the product to be guided with high precision, well balanced, and formed with high precision, enabling the production of complex castings of all kinds.

During the pouring process, the exhaust of the mold and the filling of the molten metal are faster due to the increase of the tilting speed, which effectively improves the product quality of the casting and the qualified rate of the casting.

What are the characteristics of gravity casting machine?

1. The product has low density. Relying on liquid self-weight molding, the compactness of low-pressure casting machine products is lower than that of die casting, and its strength is slightly worse, but its elongation is higher.

2. The surface finish of the product is not high. The surface of the cast product is prone to form pits similar to shot blasting after cooling and shrinking.

3. There are few pores in the casting, and the front of the product after heat treatment can be greatly improved, even exceeding that of the die-casting product.

4. The mold life is longer than that of die casting, and the mold cost is low.

5. Slow filling and low production efficiency.

What are the precautions for gravity casting in the production process?

🚩When baking the mold:

• The grill should be made according to the mold specifications, so that the temperature of the baking mold is uniform;

• Safety precautions should be taken when the mold rack is ignited, and a device that can adjust the life of the aluminum alloy gravity casting mold and the size of the flame should be installed on the grill tube.

🚩Before production:

• Whether the air outlet of the air duct is blocked and whether the interval is appropriate;

• The gap between the air outlet and the bottom of the hole should be 5 to 10mm;

• The spraying temperature should be well controlled and should be around 200℃;

• The oil-based paint can only be used for the lubrication of the slide rail, and cannot be dripped elsewhere, otherwise it will cause problems.

What is a gravity casting machine used for?

Gravity casting machine is a machine that is often used in the foundry industry. The castings produced by gravity casting machine are widely used. It can produce automobile, motor, hardware, communication base station parts, automobile industry, furniture, valve body, water pipe and many other fields. casting products.
