Extrusion Parts: The Backbone of Many Industries

Jul 01, 2024

Extrusion Parts Overview

To begin with, extrusion parts play a vital role in various industries such as car making, construction and aerospace. These parts are produced through an extrusion process which is a process of forcing hot plastic or metal via a mould to create a continuous profile. Therefore, the final outcome of the extruded parts are light in weight; they have great strength and can be used for multiple purposes.

How Extrusion is Done

The first step in the process is selecting the right material to use depending on what one wants to manufacture and this may either be steel, aluminium, copper or plastic. This material is then heated until it turns semi- molten before being pushed under pressure through a die. The die has a particular shape that is pre-set so it stamps the desired finish into the extruded material. Once the material has left the die it cools down and is cut into lengths as per each individual part.

Benefits of Using Extrusion Parts

Compared with other manufacturing methods of items, there are several advantages associated with using extrusion components. Firstly, this process allows production of complex shaped parts with accurate dimensions hence high accuracy and repeatability are ensured. Secondly, this process enables long continuous profiles to be manufactured at once and thus increasing efficiency. The result is less wastage and better utilization of materials. Also, compared to other techniques for producing items, there’s possibility that products made from extrusion method will often have higher strength-to-weight ratios (SWR) especially when those products were designed specifically for lightweight applications.

Extrusion Parts Application Areas

Many industries adopt these extruded parts in their operations. In automobile industry for example; aluminum profiles that are extruded form light-weight chassis members among others such as doorframes and window trims (Hausner 2013). On that note; in building industry framing materials like doors/window components along with siding are all examples of extrusions. Meanwhile, the aerospace industry largely depends upon extrusion parts for crafting aircraft fuselage, wings and other structural elements. Finally; electrical/electronics use extruded parts in manufacturing wiring ducts, connectors and other components.


Finally, the various industries such as those mentioned above continue to significantly rely on the strength of these light weight products that provide accurate dimensional capabilities. Extrusion process allows accurate production of complex shapes with high repeatability for applications that require different sizes of similar items. Thus, given the rising rate at which technology is advancing at present; one can reasonably predict a greater demand for such products over the next few years in order to fit within the evolving manufacturing trends in an era now referred to as industrial revolution 4.0.
