A Brief History of Signature Aluminum Extrusion

A Brief History of Signature Aluminum Extrusion

Signature Aluminum extrusion process has application in various innovation since its very first introduction around hundreds of years. From its earlier utilization in creating wires and pipes to futuristic appliances in the space stations constructions, aluminum extrusion includes a very big history.

The process of aluminum extrusion was first time patented in the year 1797 for the purpose of making lead pipes that was done manually by labors until hydraulic powered press was introduced in the year 1820. In the last of 19th century, the methods of extrusion were in use for brass and copper alloys, however application of the aluminum extrusion went through unique path.

Aluminum Origin

In Contrast to different metals like bronze, copper, steel and iron that have been being used for a great many years, aluminum is generally the latest or all, having been recognized as an essential metal in year 1807. Metal aluminum was first time refined in 1825. Around then it was viewed as a plush metal that was costly as compared to gold. It wasn’t until late 1880s, the creation of the purifying procedure by Heroult and Hall and the advancement of industrial production, the silver metal ended up being more affordable for daily uses. The underlying working procedures comprised of casting, forging and rolling

Aluminum Extrusion Process

Alexander Dick devised the cutting edge heated extrusion process in the year 1894 that become practical material to most of the non-ferrous composites. In today’s world, aluminum is one of the most common extruded metal. It can be utilized with both cold and hot extrusion profiles. North America had its very first extrusion press for aluminum, in Pennsylvania, in 1904. The presentation of extrusion made a rise in advance applications for aluminum, especially in the assembling of car parts.

The expanding interest for aluminum extrusion achieved new statures at the time of WWII for use in manufacturing air crafts and various other military necessities. The fast advancement of extrusion proceeded after World War II, and started to venture into different businesses including the private lodging division, which experienced considerable development in the after war time frame.

In following decades, constructions and transportation industries have always been one of the principal beneficiaries of the aluminum extrusion services. In present era, bulk of extrusion utility is in windows and doors manufacturing, followed by vehicles. Other leading extrusion applications and products are construction of highways and bridges and consumer staples.

The history of signature aluminum extrusion, as compared to various other metals, has seen an extensive growth and development, revolutionizing our living style.

Aluminum is best for extrusion processes because of its malleable characteristics that allow for producing diversified shapes. Such extrusion shapes can also be customized to accurate specification and measurements for numerous applications.

Regular and commonly known shapes are channels, angles and tubing that are primarily used in cars, computers and domestic applications. They can range in dimensions from smaller as 1 millimeter to very large.

Manufacturing Custom Shapes By Using Aluminum Extrusion

Unique or custom shapes are developed in aluminum extrusion process by using custom-designed dies. On heating aluminum billets are stricken through die in extrusion press, shape of die functions as mold to define uniform cross-sectional final shape. Dies can be changed easily and less costly, allowing production of various shapes without noticeable rise in time and cost of production.

Dies created can meet specifications needed for product, to make them hollow, semi-hollow and solid even. As soon as die has designed, it is retained for reuse in future.

Advantages of Aluminum Extrusion for creating shapes

Other processes are also there for manufacturing needed customized shapes, but aluminum extrusion process has its particular benefits which makes it an ideal option for fabricating various products.

You get multitude of design options at economical cost, leading to the benefits of its vast potential of uses. 

Aluminum extrusion process is easy to work with complex shapes or cross-sections which are designed to have non-uniform width required.

Aluminum extrusion process can produce single shape products much more easily, bypassing needs for joining and welding, thus reduce manufacturing costs.

Aluminum extrusion process is also very convenient to include tongue and groove, sliding or snap fit, press, self-tapping functions in aluminum extrusions, by particularly designing extruded shapes.

Application of Aluminum Extruded Shapes

  • Additionally, aluminum extrusion also comes with standard shapes, like beams, bars, pipes, hexes, rods, z-bars, Ts, and the like. Such shapes are used in both interior and exterior applications, and industries below.
  • Constructions and building industry utilizes aluminum extrusion shapes for doors, windows, architectural framings, shop fronts, window frames, roofing and exterior cladding.
  • For automotive and transportation industries aluminum extruded shapes extensively used for railway coaches, marine applications, automobiles, and aerospace.

Utilization of aluminum extrusion shapes are continuously experiencing substantial growth, with increase in available choices and ability to design dies for particular customized shapes.
