FAQ
1. How to prevent the formation of air holes in castings?
The effective methods to prevent bubbles are: reducing the gas
content in the metal liquid, increasing the air permeability of
sand mold, and adding an air riser at the top of the mold cavity.
2. How to avoid the situation of sticky sand?
The surface of the casting is adhered to a layer of sand which is difficult to remove.It not only affects the appearance of casting, but also increases the workload of casting cleaning and cutting, and even affects the life of the machine.The method to prevent the formation of sand is to add coal powder in molding sand, and to brush the surface of the cast mold with anti-sand paint.
3. How to identify shrinkage?
(1) Observe the surface shape of casting defects. If the surface is uneven, very rough, and dark gray, the hole with irregular shape is shrinkage cavity.
(2) If the location of the hole is at the final solidification thickening of the casting, or at the hot spot where the two walls intersect, and is located in the middle or upper part of the section, it is a shrinkage cavity.
(3) The most concentrated hole defects on the thick and large section of steel castings are shrinkage or air shrinkage.
