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.

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.  

  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.

                                             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.
