Bronze Casting Processes for

Oil-less Bearings(3)

Extrusion is a forming process that enables the continuous production of tubular or rod-shaped products with a uniform cross-section by extruding material through a mold. The material coming out of the mold is called the extrudate, and non-metals such as ceramics, plastics, and polymers are also suitable for extrusion.

Extrusion at room temperature is called cold extrusion, and extrusion by heating the billet above its recrystallization temperature to soften the metal is called hot extrusion. The extrusion process has a high initial cost and requires high compressive force, but it has many advantages technically and economically.

Characteristics

① Possible from simple profiles in the form of hollow and round bars to complex profiles

② Since compressive and shear force are applied to the billet, brittle and ductile materials can be worked.

③ High extrusion rate (less waste and high production rate)

④ High flexibility in shape and size with simple mold replacement

⑤ Excellent grain structure in a material direction

Extrusion is used in various applications, such as tubes and hollow pipes, industrial structures, frames in the automotive industry, doors, and windows.

SGO keeps extruded bars and plates in high-strength brass (C86300/CuZn25Al5) in stock, and please check available sizes if you have any inquiries.
