Everything You Need to Know About Aluminum Extrusion Molding

Extrusion molding is highly adaptable. It is possible to make items of various shapes, sizes, specifications, and types on the same equipment by simply switching out the molds.

FREMONT, CA: Aluminum extrusion molding is a type of plastic processing technique that applies high pressure to the metal blank in the mold cavity (or cylinder), forces the metal blank to undergo directional plastic deformation, and then extrudes from the die hole to obtain the required section shape and specific mechanical properties of parts or semi-finished products.

Key Benefits of Aluminum Extrusion Molding

Comprehensively superior product quality: Aluminum can enhance its structure and mechanical qualities by extrusion molding. After quenching and aging, extruded products' longitudinal (extrusion direction) mechanical qualities are significantly greater than those of identical products generated by other processing methods. Compared to rolling, forging, and other processing techniques, extrusion yields outcomes with superior dimensional precision and surface quality.

A variety of items: Extrusion can not only produce a simple tube, rod, or wire, but it can also produce a section with a very complex cross-sectional shape, solid and hollow profile products with variable cross-section profiles along the length direction, and many of these products have cross-sectional shapes that are inaccessible to other plastic processing techniques. Extruded goods are available in a wide range of sizes, from extra-large pipes and profiles with a diameter of 500-1000mm to ultra-small precision profiles the size of a matchstick.

Excellent versatility in production: Extrusion molding is highly adaptable. It is possible to make items of various shapes, sizes, specifications, and types on the same equipment by simply switching out the molds. In addition, changing molds is straightforward, practical, time-consuming, and effective.

Straightforward method and low equipment investment: Compared to pipe and profile production procedures such as perforated rolling and groove rolling, extrusion molding offers a shorter technological process, fewer pieces of equipment, and a lower initial investment.

Disadvantages of Aluminum Extrusion Molding

Uneven performance of tissue products: The surface layer, center, head, and tail of extrusion products are not uniform because the flow of metal during extrusion is not uniform (this is especially severe when there is no lubricating forward extrusion).

The working conditions of the extrusion die are arduous and easily degraded: During extrusion, the blank is in a virtually closed condition and is subjected to intense three-way pressure. During hot extrusion, the mold is typically exposed to high temperatures and high friction, which significantly impacts its durability and service life.

Low production productivity: The conventional extrusion methods cannot achieve continuous manufacturing in addition to the continuous extrusion method developed recently. The extrusion speed is generally considerably slower than the rolling speed, and the geometrical waste loss and extrusion production yield are low.
