Die Casting Porosity Causes – Die casting is a method of forcing molten metallic materials, plastics and resins inside a molding machine and allowing it to cool down until it solidifies. The materials eventually acquire the shape of the mold. However, there are unsolicited finished products wherein the material contains air bubbles and void space inside the molded material. When this happens, the material becomes weaker and easier to break. This is why porous casts are often categorized as poorly made and of low quality. Die Casting Porosity causes the material to develop cracks, chinks and notches because of its unstable density. Porous materials are also usually made of low-class materials such as less cohesive and less pure resin and metal materials. Materials with thinner consistency tend to develop bubbles and air pockets within them when they harden. Fortunately, by following simple tips, you can avoid having air bubbles in your molded materials.

Have your molding machines checked up regularly for any cracks on the surface as these cracks can permit air to seep through the machine and cause bubbles within the material. Covering the molding surface with a sealant effectively reduces the occurrences of air bubbles. Try to use high-grade materials such as pure aluminum to assure that it is more dense compared to substandard and less-stable metallic substances. You can also opt to use vacuum devices to suck out the air as soon as the machine compresses the molten metal to remove any excess air which may cause bubbles inside. However, it is a bit more expensive than other machines, but investing on it will greatly reduce casting porosity.

Kinetic Die Casting utilizes die casting to manufacture parts like aluminum car parts, airplane parts, lighting parts and much, much more. If you would like to request a quote, please visit our website:Die Casting quote
