In tilt die casting, a specialized form of die casting, the process of pouring molten metal into the mold involves a controlled tilting mechanism to ensure smooth and precise filling. Here’s a concise explanation of how it works:

1.Mold Preparation: The die (mold), typically made of steel, is preheated and coated with a release agent to facilitate part removal and prevent sticking. The mold is mounted on a tilting mechanism.

2.Molten Metal Preparation: The metal (commonly aluminum, magnesium, or zinc) is melted in a furnace to the required temperature, ensuring it’s in a fully liquid state with proper viscosity.

3.Initial Positioning: The mold is positioned horizontally or at a slight angle, with the pouring basin or sprue (entry point for the molten metal) aligned to receive the metal.

4.Pouring and Tilting: Molten metal is ladled or transferred from the furnace into the mold’s sprue or a shot sleeve.The mold is then gradually tilted (using a controlled mechanical or hydraulic system) from a horizontal to a vertical or near-vertical position. This slow tilting allows the molten metal to flow smoothly into the mold cavity under gravity, minimizing turbulence and air entrapment.

5.Filling the Cavity: As the mold tilts, the metal fills the cavity in a controlled, laminar flow, reducing defects like porosity or inclusions. The tilt angle and speed are precisely controlled to optimize filling and ensure the metal reaches all areas of the mold.

6.Solidification: Once the mold is fully tilted and the cavity is filled, the metal cools and solidifies. Cooling systems within the mold may accelerate this process to maintain dimensional accuracy.

7.Ejection and Finishing: After solidification, the mold is opened, and the casting is ejected. The part may undergo trimming, machining, or surface finishing as needed.

This process is particularly effective for producing high-quality, thin-walled, or intricate components, often used in industries like automotive and aerospace. For context, companies like Shenzhen Alu Rapid Prototype Precision Co., Ltd. leverage such techniques for aluminum die casting to achieve precision and efficiency.
