Titanium Metal Extrusion Casting Methods and Material Research

Titanium metal is widely used in various industries due to its excellent properties, high strength, low density, and outstanding corrosion resistance. One of the key manufacturing processes for titanium components is extrusion casting, which offers versatile methods for shaping titanium alloys with complex geometries.

Direct Extrusion Casting

Direct extrusion casting involves injecting molten titanium metal into an open mold, followed by rapid mold closure and the application of high pressure. Under the influence of pressure, the titanium metal solidifies while undergoing slight plastic deformation, resulting in dense billets or parts. This method necessitates strict control over the melting temperature and casting speed to prevent metal oxidation and gas entrapment.

Indirect Extrusion Casting

Indirect extrusion casting employs a punch to apply high pressure to molten or semi-solid titanium metal, forcing it into a closed mold cavity for solidification and shaping. This technique enables better control over metal flow and solidification processes, thereby reducing the occurrence of defects in the final products.
