Benefits of Gravity Die Casting

Gravity die casting is basically used to fabricate metal alloys with dense, high-quality mechanical attributes. At times it is also referred to as permanent mold casting. This process includes pouring molten metal into molds with the help of a ladle and it even relies on gravity alone to fill them. The gravity method led to various benefits which include faster production times, smoother surfaces, and exceptional dimensional accuracy.

In this particular process, the molten metal is poured directly into a semi-permanent or permanent die with the help of a ladle which then can be fully automated.

Compared to other processes gravity die casting process also tends to be more cost-effective. It is because it does not need any large or complex machinery to inject the metal into the molds. Along with that, the molds themselves are reused indefinitely. It then reuses the wasted time and resources which are required to constantly produce new dies. This method then produces high-volume, quality casts that need very little finishing.

Alternatives to Gravity Die Casting

Rather than gravity dies casting aluminum die casting is often used for larger production orders. The use of sand casting is in creating three-dimensional hollows and complex molds. It usually has higher tooling costs.

Materials & Process of Gravity Die Casting

This method typically works best with non-ferrous alloys like aluminum and copper. It is performed manually but in certain circumstances, it can also be automated. This is a simple process: at first, the mold undergoes heat treatment, and then the coating is given with a lubricating die release, which then is easily removed after it has cooled. Then, into the cavity, the liquid metal is poured and allowed to flow.

Automotive Industry & Gravity Die Casting

Gravity die casting manufacturers invest in well-designed, significantly tooled permanent molds, which results in valuable consistency. Due to the long-term reusability of the molds surface details are reliably reproduced. It is formed using durable materials like stainless steel, grey cast iron, and graphite. Although for simply shaped, single-part molds gravity casting works best. It even produces more complex casts effectively.
