Recently, a high-precision aluminum extrusion mold technology has attracted attention in the field of automotive parts manufacturing. The successful application of this technology has significantly improved the production efficiency of automotive crash beams and is expected to reshape the manufacturing pattern of automotive safety components.
The manufacturing of automotive crash beams has always faced many challenges. Taking the production of anti-collision beams using 6082 grade aluminum alloy as an example, traditional molds adopt a center opening and hole preparation structure. Although it can ensure the formation of aluminum extrusion materials, the breakthrough pressure of aluminum extrusion can reach up to 280MPa, which is close to the limit of the press. There is a high pressure build-up at the top of the mold for 20-25 seconds, which causes the surface of the product to heat up too high due to the large shear force, leading to problems such as cracking and dealumination, greatly limiting the aluminum extrusion speed and production efficiency.
To solve these problems, the R&D team has made unremitting efforts and launched a new type of high-precision aluminum extrusion mold. This mold boldly innovates in the design of the mold core, with a first center spare hole set near the first rib cavity and a second center spare hole set near the second rib cavity. At the same time, the welding chamber depth is accurately adjusted to 2-2.5cm. Through these optimizations, the flow friction of aluminum extrusion metal is significantly reduced, the pressure of aluminum extrusion mold is significantly reduced, and the surface temperature of aluminum extrusion mold is effectively controlled.
Actual production data shows that after using the new mold, the extrusion production speed has been significantly improved, and the production efficiency has made a qualitative leap compared to the past. Not only that, the product quality is also more stable and reliable, providing a solid guarantee for the safety performance of automobiles.
Industry experts point out that the application of high-precision aluminum extrusion mold technology is a major innovation in the field of automotive parts manufacturing. It not only helps automobile manufacturers effectively improve production efficiency and reduce costs, but also further enhances the quality standards of automobile crash beams. With the gradual promotion of this technology, the automotive industry is expected to achieve new breakthroughs in safety performance and production efficiency.
This technological breakthrough demonstrates the industry's spirit of continuous progress driven by innovation. In the future, relevant enterprises will continue to increase research and development investment, continuously improve technology, and inject new vitality into the high-quality development of the automotive industry.
