The International Magnesium Association (IMA) will hold the 79th World Magnesium Congress in Barcelona, Spain from August 29 to 31, 2022. During the conference, China Magnesium Technology Co., Ltd. was honored to receive the Excellence Award of the 2022 International Magnesium Association “Commercial Casting Award”.
In particular, it is worth mentioning that this is the second award. Guangzhou Magnesium, one of the parent companies of China Magnesium Technology, and Mobike won the 2018 International Magnesium Association “Commercial Casting Award” Excellence Award for their revolutionary development of magnesium alloy shared bicycle integrated wheel castings.
The China Magnesium Technology team has continued to explore the field of magnesium alloys and won this honor again. Special thanks to Rick, Chairman of the International Magnesium Association, and Jon, the Chairman of the Judging Committee, for accepting the award on behalf of our company at the Spanish conference. It is a great honor to be recognized by professional associations and reviewers!
This award-winning project is the first 27.5-inch one-piece magnesium alloy frame developed by China Magnesium Technology. Among them, there are mainly two highlights: first, it is the world’s first super-sized magnesium alloy frame; second , Using the integrated die-casting process pioneered by China Magnesium.
This one-piece frame, without welding joints, is installed with the Bafang central motor, and is formed by a 3000-ton locking force die-casting machine at one time. By combining magnesium alloy materials with injection molding technology, China Magnesium Technology is now able to produce lightweight, rigid frames with hollow tube geometry. This frame is 30% lighter than the traditional aluminum alloy frame, and can be restored to its original shape when it is deformed by an impact. It has good shock absorption, making the riding experience better, and truly achieves light travel.
And, compared with the current state-of-the-art technology, these magnesium alloy frames are 100% recyclable, reducing carbon emissions by 50% during the manufacturing process, in line with current green emission reduction requirements, and very environmentally friendly.
General Manager Feng of Taishan Zhongmei Technology Co., Ltd. said: “We have finally brought a milestone change to the mass production of bicycle frames. With our first one-piece large-size magnesium alloy electric bicycle frame, Zhongmei Technology proves that it is possible to efficiently mass produce lightweight, large-scale integrated bicycle frames with extremely high stiffness in China. Each mold of Zhongmei Technology can produce 600 frames a day; a single robotic arm, less than 120 seconds A complete frame can be produced in one shot without any welding lines. With high output, it saves production costs, increases efficiency, greatly reduces defects, and reduces CO2 emissions by more than 50%. At the same time, Compared with aluminum frames, the frame has higher stiffness, lighter weight and better riding experience. This is a revolution in the production technology of bicycle frames. Our factory can produce up to 2 million per year A bike frame. We look forward to seeing the extraordinary impact this will have on the industry!”
Cold-chamber die-casting is that the robotic arm pours the molten metal liquid into the injection chamber by feeding the soup from the middle of the machine through a spoon, and then uses the injection piston (hammer) to push the metal liquid into the mold at high speed, while maintaining a certain pressure. A casting equipment that cools and solidifies to obtain finished products. His advantage is that it does not need manual reclaiming and has a high degree of automation. The surface of the die-cast product is smooth and flat, with high strength and hardness, and the thickness of the product is thin. The products made do not need secondary processing, but one-time molding, which can realize the industrialization and integration of production, so as to achieve the effect of reducing cost and increasing efficiency.
Cold chamber die casting is currently the most widely used alloy die casting process on the market, and our company is very mature in this application. We have used this process to cooperate with well-known car companies such as Mercedes-Benz, Ford, BYD and other auto parts such as steering wheels, gearboxes and other auto parts, as well as Yadi, Emma, Mavericks, Xidesheng and other two-wheeled vehicle frames and axles. The one-piece molding process we do can make these products very simple and beautiful in appearance without welding ports.
Looking forward to business technical exchanges and cooperation with China Magnesium from all walks of life, thank you. Interested parties can send email: sales@zhongmei-tech.com.
