Recently, a client from the Middle East visited our factory and intended to purchase an aluminum extrusion press for manufacturing door and window materials.
We recommended the customer to purchase a 5-inch extrusion press, specifically our 1100T aluminum extrusion press. Through our discussion, we realized that the customer had limited knowledge about extrusion presses. Previously, he used to purchase aluminum materials for making doors and windows, but now he plans to buy an extrusion press to produce aluminum materials himself.
Someone had suggested that he should buy an 1800T aluminum extrusion press for producing door and window aluminum materials. However, based on the sizes of the door and window materials he needs, we recommended the 1100T aluminum extrusion press instead.
Our Huanan 1100T aluminum extrusion press is also a 5-inch aluminum extrusion press, which is suitable for extruding various door and window aluminum profiles. The extrusion cylinder specifications of our 1100T aluminum extrusion press machine are:
Diameter: 132mm
Length: 800mm
Applicable aluminum billet size:
Diameter: 127mm
Length range: 400–750mm
Considerations When Extruding Aluminum: Extrusion Pressure
When extruding aluminum, it is crucial to consider the extrusion pressure. If the extrusion press tonnage is too high relative to the aluminum billet diameter and alloy type, the following issues may occur:
1. Over-Extrusion
Excessive Metal Flow Rate: Too much pressure can cause excessively fast metal flow, affecting dimensional accuracy and surface quality.
Overheating: Excessive extrusion pressure can lead to rapid temperature rise, potentially causing surface roughness, cracks, or even burning.
2. Mold and Die Damage
Shortened Die Lifespan: Excessive pressure may exceed the die’s load capacity, leading to rapid wear or even breakage.
Die Deformation: Continuous use of an overpowered press can cause plastic deformation of the die, affecting profile accuracy.
3. Equipment Damage
Accelerated Extrusion Cylinder Wear: Higher pressure accelerates wear on the inner wall of the extrusion cylinder, shortening its lifespan.
Hydraulic System Overload: If the tonnage is too high, the hydraulic system may overheat, experience pressure failures, or even develop leaks.
4. Negative Impact on Product Quality
Coarse Grain Structure: Excessive extrusion speed can lead to larger metal grains, reducing mechanical performance.
Increased Defects: High stress and temperature may introduce bubbles or inclusions inside the aluminum, affecting product quality.
Reduced Dimensional Accuracy: Overpowering the extrusion process may lead to unstable profile dimensions and out-of-tolerance products.
5. Increased Production Costs
Higher Energy Consumption: A high-tonnage extrusion press consumes more energy, leading to unnecessary waste if the press is oversized.
Increased Maintenance Costs: Faster wear and tear on molds, extrusion cylinders, and hydraulic systems lead to higher maintenance and replacement costs.
Choosing the Right Extrusion Press
When purchasing an aluminum extruder, it is essential to determine the size of the aluminum profiles to be produced and ensure that the press tonnage is appropriate.

Finally, we took our Middle Eastern client to the production line to observe the entire mechanical production process and inspect the 5-inch aluminum extrusion machine in action. This helped the customer better understand the Aluminum extrusion process and the necessary machinery, giving him a clearer view of the entire aluminum manufacturing process.
