Materials & Specifications
Materials used in our extrusion process include, Metals: Aluminum (2xxx series and 7xxx series), Brass, Bronze, Copper, Carbide Aluminum, Stainless Steel, and Steel. Commonly used plastics include Acrylic, Butyl, Foam, Polyethylene, High Density Polyethylene, Polypropylene, High Density Polypropylene, Neoprene, Polyvinyl Chloride (PVC), Rubber, Polyurethane, and Vinyl.
Additionally, extrusion generally minimizes the need for secondary operations, but does not provide the same dimensional accuracy or surface finish as machined parts. The surface finish for steel is 3 microns (125 uin) and for aluminum and magnesium is 0.8 microns (30 uin). However, the process can produce a wide variety of cross-sections that would be difficult to produce cost-effectively using other methods. The minimum thickness for steel is approximately 3 mm (0.120 in), while the minimum thickness for aluminum and magnesium is approximately 1 mm (0.040 in). The minimum cross-sectional area for steel is 250 mm2 (0.4 in2), while for aluminum and magnesium it is less than 250 mm2. Minimum corner and fillet radius of 0.4 mm (0.015 in) for aluminum and magnesium, 0.8 mm (0.030 in) for steel and 4 mm (0.120 in) for corners

What is Extrusion?
Extrusion is a manufacturing process widely used in various industries to create objects with a consistent cross-sectional profile. It involves pushing or forcing a material, typically a malleable plastic or metal, through a die to form a continuous shape. The initial step entails introducing the raw material, typically in the form of pellets, into a hopper. Subsequently, the material is conveyed into a heated barrel. Within the barrel, the material is melted and pressurized, and it is then forced through the die, which determines the final shape and size of the extruded product. Cooling mechanisms are employed to solidify the material as it emerges from the die. Extrusion offers several advantages, such as high production rates, versatility in creating complex shapes, and cost-effectiveness. It is commonly used to manufacture products like pipes, tubes, rods, and various profiles used in the construction, automotive, and packaging industries.
Types of extrusion processes
There are four significant types of extrusion processes that are used to produce objects of different quality. At Elimold, our expert team covers all operations to deliver you the best quality end products.
Direct extrusion, also referred to as forward extrusion, is the most common metal extrusion method. With this type of extrusion, a billet of material is pushed through a container by a high-pressure ram. The material flows in the direction of the ram motion and exits through the opening of the stationary die. Direct extrusion allows for larger profile designs and a higher quality surface finish than the indirect extrusion method.
There are some disadvantages to consider with this method. A large amount of friction generates between the material and the walls of the container, which results in decreased die-face pressure and temperature variances. These factors make it more challenging to control dimensional consistency and the material’s properties.
With indirect extrusion, the material is placed into a container and secured. The extrusion die moves with a hollow ram over the material, forcing it through the die opening. Indirect extrusion is also sometimes referred to as backward extrusion because the material flows in the opposite direction of the ram motion. Since there is no relative movement between the material and container, there is much less friction with this method, resulting in lower energy use and less heat generation. With less heat, indirect extrusion generally has greater control over dimensional consistency, material properties, and grain size when compared with direct extrusion.
However, the drawback to this type of extrusion is a more significant limitation on overall die profile size, as it must fit inside the hollow ram. The billet’s surface impurities can find their way into the extruded product reducing the overall surface finish and aesthetics.
These are sub-categories of extrusion integrated into the primary methods discussed above. The temperature of the billet relative to the room and material recrystallization temperature defines hot, warm, or cold extrusion. Hot extrusion is when the billet is heated well above the material’s recrystallization temperature, often associated with the direct extrusion method. The heating of the material softens it and prevents work hardening, so it more easily flows through the die, reducing wear on the tooling. Warm extrusion is when the material is heated above room temperature but remains well below the recrystallization point. The material is not heated in cold extrusion and remains at room temperature.
Warm and cold extrusion can increase the hardness and strength of the extruded product due to no excessive raw material heating. These processes work best with high-ductility materials, such as aluminum. The warm and cold processes are typical of the indirect metal extrusion method. While not drastically heating the material can provide benefits, it can be harder on the tooling and reduce the lifetime of the die. With this in mind, most manufacturers opt for hot extrusion methods.
Extruded aluminum makes up roughly 80% of all extruded metal products due to its versatility across industries, mechanical properties, diverse finishing options, and high flexibility, making it ideal for extrusion processes. Most extruded aluminum alloys are lightweight, resistant to corrosion, and have high thermal and electrical conductivity. Some aspects of each alloy set it apart from the others. To help you choose the right one for your project, we have compiled a table below of our most commonly used alloys and their unique characteristics.
