Custom Extrusion And Its Best-Known Industrial Applications

Custom Extrusion And Its Best-Known Industrial Applications


With the recent advancements in technology and manufacturing processes, manufacturers can produce many products and conveniences in specific custom shapes using custom extrusion.Get more news about Micro Precision Cold Extrusion Part,you can vist our website!

These products and items include straws, PVC pipes, rain gutters, and more. If you’re genuinely interested to better understand the manufacturing process behind these widely known products and how they work, read through our informative article and broaden your horizons on custom extrusion.
What Is Custom Extrusion?
Extrusion is the manufacturing technique of forming products by pushing materials like aluminum or plastic onto a mold to create a particular shape. Consequently, custom extrusion is an extrusion that’s custom-made to form specific shapes and materials.

The manufacturing process involves forcing base plastic, metal, or other material through a pre-shaped die to produce items with a specific shape and profile. As the material passes through the die, it’s shape changes to reflect the die’s shape.

As a rule, the best material for custom extrusion is aluminum because it resists corrosion. Furthermore, when you take advantage of aluminum with another kind of metal, you will end up with something that’s called galvanic corrosion.

Extrusion can be done continuously for a long material or semi-continuous for the manufacturing of a larger quantity. Besides aluminum and plastic, some of the other standard materials used for extrusion include concrete, clay, ceramics, polymers, etc.Custom extrusions are usually done by professional plastic and aluminum extrusion services that can transform high-quality plastics and aluminum alloys into specified shapes to meet desired specifications.
Hot Extrusion
On the other hand, hot extrusion requires heating the material at very high temperatures and afterward forcing it within the die while in a molten phase. Highly depending on the type of material used, temperatures may range from 650-850 Fahrenheit for magnesium and up to 1,300 Fahrenheit for steel.

Using an adequate temperature is very important when performing hot extrusion because if the base material isn’t heated to its recrystallization temperature, it may struggle to move through the die. When the material is heated to the appropriate temperature, hot extrusion is an effective and accurate way to shape and reshape products and components.
Friction Extrusion
Invented by The Welding Institute in the UK and patented in 1991, friction extrusion was initially intended to produce homogenous microstructures and particle distributions in metal matrix composite materials.

The modern friction extrusion process involves the automatic twist of the billets or metal slugs based on the die’s position. As the die rotates, it creates heat from the metal-on-metal friction around the entry of the die. Consequently, the heat allows the metal to pass through the die more quickly and form the new shape.

Friction extrusion is a highly effective and efficient manufacturing process gaining popularity among professional manufacturers from all industries.

Micro Extrusion
At last, micro extrusion is the newest type of extrusion technique characterized by its ability to produce small and micro-sized objects because the cross-section of the die supports base material measuring just 1 millimeter. Due to the highly technical nature of creating such tiny dies that can withstand a lot of pressure, micro extrusion hasn’t gained the same level of popularity as its friction counterpart.
