Influence of extrusion ratio on aluminum extrusion quality

The extrusion ratio has a significant influence on the microstructure and mechanical properties of aluminum extrusions. Here's how it impacts these aspects:

1. Grain Structure:

• lHigher Extrusion Ratios: Tend to produce finer grain structures. This is because the increased flow and deformation can promote more uniform and finer grain refinement. Finer grains generally enhance the strength and toughness of the extruded material.
• lLower Extrusion Ratios: May result in coarser grain structures. Coarser grains can lead to reduced mechanical properties compared to those with finer grains.

2. Mechanical Properties:

• lStrength and Hardness: Higher extrusion ratios often lead to improved strength and hardness. The fine-grained structure resulting from higher ratios contributes to better mechanical properties.
• lDuctility: The impact on ductility can be variable. While higher extrusion ratios typically improve strength, they can sometimes reduce ductility if the metal flow induces internal stresses or defects.
• lTensile Properties: Extrusions with higher ratios can show better tensile properties due to more uniform microstructure and reduced porosity. However, achieving these benefits requires careful control of other process parameters.

3. Homogeneity:

• lMaterial Homogeneity: Higher extrusion ratios can lead to more homogeneous material properties along the length of the extrusion. This is because the increased flow helps to distribute alloying elements and reduce segregation.

4. Internal Defects:

• lInclusions and Voids: Higher extrusion ratios can reduce the incidence of internal defects such as inclusions and voids, as the extrusion process tends to consolidate the material more effectively. However, excessive ratios can introduce new challenges, such as increased risk of billet cracking or die clogging.

In summary, the extrusion ratio is a crucial parameter that influences multiple facets of aluminum extrusion quality. While higher extrusion ratios often enhance mechanical properties and material homogeneity, they can also introduce challenges related to die wear, surface finish, and dimensional tolerances. Balancing these factors is key to optimizing the extrusion process and achieving the desired quality of the final product.

                                           Aluminum Extrusion press for prestressed composite frames

A solid extruder structure is a prerequisite for ensuring the performance of the extruder. After being used for a period of time, many Aluminum extrusion machine become loose, the interfaces age, and the cylinders bend, resulting in deformation and unstable quality during the aluminum extrusion production process. In fact, the main reason is that the extruder as a whole is not strong enough.

The stress during the operation of the extruder is very large, and our extruders mostly adopt a prestressed composite frame structure, which is composed of a high-thickness integral front beam, a high-thickness rear beam, and a square prestressed sleeve to form a closed The prestressed composite frame uses a special hydraulic preloading tool to apply an overpressure tensile load to the entire length of the tie rod, and at the same time applies compressive stress to the pressure sleeve, so that the entire frame is in a stress pretightened state, and the tension column prestress is 115% of the maximum load. above. For example, our 7500-ton hydraulic extrusion press has a front beam thickness of 1950mm made of ZG35Mn, a rear beam thickness of 1800mm (material ZG35Mn), and a square pre-applied sleeve (material ZG35). It can make it bear force better, which is also an important reason for the long service life of the extrusion machine.

Other advantages of prestressed composite frames

1. The center distance of the four stressed tie rods of the frame is symmetrical to the center of the press, so that the entire frame is stressed evenly. The main reason why the quality of aluminum materials produced is stable or unstable is whether the force is uniform. Only by maintaining uniform force can the overall density of the aluminum material be uniform, thereby improving the accuracy of extruded products.

2. The prestressed composite frame frame has a larger bending section, which makes the frame elongation and bending deformation smaller under the action of extrusion force. Therefore, the extrusion beam and the lower part of the extrusion tube can be fixed on the lower frame. The horizontal and vertical guide rails are very convenient for centering adjustment between the extrusion beam, extrusion barrel and mold. The upper frame can be used as an X-shaped moving guide rail for the extrusion barrel. On the premise of ensuring the stability of the machinery, the available space is used to reduce the space occupancy of the machinery.

3. There are two sets of elastic anchoring devices and foundation anchors on the lower part of the rear beam to make the rear beam fixed reliably.

After many years of production experience and continuous improvement based on customer feedback, our extrusion press is currently one of the most stable extruders on the Chinese market and one of the longest-lasting Aluminum extrusion machine.

Extrusion oil and cutting fluids are essential components in the aluminum extrusion machine and deep processing of aluminum profiles. With the increasing demand for high-precision metal processing in the manufacturing industry, metalworking fluids are evolving towards being more environmentally friendly, of higher quality, and technologically advanced. For aluminum extrusion machines, which are large-scale equipment, the comprehensive performance requirements of hydraulic oil are very stringent. Poor-quality hydraulic oil can disrupt normal equipment operation, leading to production line stoppages and significantly impacting the economic benefits of the entire workshop.

Just as engine oil is crucial to the functioning of a car, hydraulic oil is vital to the machinery. It is imperative to further reduce the friction coefficient of hydraulic oil, which will enhance the efficiency and stability of the extrusion press.

Our aluminum extrusion machines have very stringent requirements regarding hydraulic oil and hydraulic systems. We use the most advanced hydraulic oil and systems in the industry. The pump station of the extrusion machine features an integrated design, centrally located at the rear bottom of the machine's oil tank. The system uses imported German Rexroth (Bosch Rexroth) electro-hydraulic proportional control axial piston variable pumps and a domestic stainless steel plate-type circulating filtration cooling system. The pipeline system is designed with necessary buffering and anti-vibration measures, such as buffer pads, flexible hoses, or vibration absorbers, and employs flexible rubber joints to absorb vibrations.

Isolation control valves are designed between the oil pump groups to ensure that when two mechanisms need to operate simultaneously according to the program, they do not interfere with each other. The system can achieve pump isolation, no-load start, pressure regulation, and overload protection functions. The pump head electro-hydraulic proportional valve and electronic control device are imported with the main pump and connected to the main control computer of the aluminum extruder, allowing for integrated control.

As one of the most critical components of the Aluminum extrusion machine, Huananmachine ensure the highest quality standards for our hydraulic oil system. This rigorous quality assurance is a key reason we confidently guarantee the quality to our customers.
