FAQ

Q

What are the characteristics of aluminum alloy die casting

A

1. Good product quality 2. High production efficiency 3. Good economic results

Q

The surface of the product is loose, which affects the strength of the product.

A

Check whether the metal is completely melted before casting, increase the metal temperature and casting pressure.

Q

The product cracks after casting, affecting the quality of the product

A

Increase metal temperature and cooling rate, control metal casting pressure

Q

Oxidation occurs on the surface of the product, which affects the quality of the product.

A

Strictly control the metal heating temperature, heating time and cooling time.

Q

Gate defect

A

Check and improve the gate shape, and increase the pouring speed.

Q

Sand particles appear on the surface of the mold, affecting the surface quality of the product

A

Check the sand mold and increase the amount of lubricant used.

Q

The sand mold loses its refractoriness and cannot withstand the invasion force of liquid metal

A

Check the sand mold material, baking time and temperature to ensure the stability of the mold.

Q

Small burrs exposed on the surface of the mold affect product quality and quality.

A

Increase the number of sand shake, sand surface spray paint to prevent sand fall.

Q

Porosity: bubbles that appear during the casting process, affecting the strength and density of the product

A

Strengthen the monitoring of batching effect and check the flow of molten metal.

Q

Shrinkage cavity: shrinkage cavity in the process of metal casting, which affects the mechanical properties of the product

A

Strengthen the pressure control during the casting process and increase the metal temperature appropriately.
