Trunnion Type Centrifugal Casting Machines

图片
Trunnion type centrifugal casting machines use a mold or flask that is supported and rotated by four trunnion wheels. These machines are used for producing castings that have lengths longer that their diameter.                          Common castings produced on trunnion type include bushings, bearings, cylinder liners, piston rings, pipe, and steel tubes and sleeves. Our automatic centrifugal casting machine all adopt trunnion type as main engine.

Centrifugal casting

Centrifugal casting, sometimes called rotocasting, is a metal casting process that uses centrifugal force to form cylindrical parts. This differs from most metal casting processes, which use gravity or pressure to fill the mold. In centrifugal casting, a permanent mold made from steel, cast iron, or graphite is typically used. However, the use of expendable sand molds is also possible. The casting process is usually performed on a horizontal centrifugal casting machine (vertical machines are also available) and includes the following steps: Mold preparation  - The walls of a cylindrical mold are first coated with a refractory ceramic coating, which involves a few steps (application, rotation, drying, and baking). Once prepared and secured, the mold is rotated about its axis at high speeds (300-3000 RPM), typically around 1000 RPM. Pouring  - Molten metal is poured directly into the rotating mold, without the use of runners or a gating system. The centrifugal force drives ...

What is Centrifugal Casting?

Centrifugal casting is a process that delivers castings of very high material soundness, and thus is the technology of choice for applications like jet engine compressor cases, petrochemical furnace tubes, many military products, and other high-reliability applications. In the centrifugal casting process, molten metal is poured into a spinning die. The die can be spinning either on a vertical or horizontal axis depending on the configuration of the desired part. Ring and cylinder type shapes are cast vertically; tubular shapes are made with the horizontal centrifugal process. Either process may be used to produce multiple parts from a single casting.  External structures and shaping can be cast in place to significantly reduce post-processing including machining or fabrication.  Because of the high g-forces applied to the molten metal in the spinning die, less dense material, including impurities, "floats" to the I.D. where it is subsequently removed by machining. Solidific...
