Lijin Group and Chery Automobile jointly lead the innovation of dual-injection technology

On December 25, an important event was recently held in Wuhu, Anhui. Lijin Group and Chery Automobile jointly held a high-profile technology conference. This event not only celebrated their cooperation in the field of double injection molding process of more than 10,000 tons, but also demonstrated the scientific principles behind this technology and its leading position. The revelation of this technology has attracted widespread attention inside and outside the industry

The cooperation between Chery Automobile and Lijin Group marks the dual injection process entering a new milestone - the "10,000-ton" era. It is expected that the successful implementation of this technology will reduce the weight of ultra-large integrated die-cast structural parts of the car body by 20%, and achieve a phased result of 33-35 yuan per kilogram in cost. This is not only a symbol of technological progress, but also heralds the huge potential of future automobile manufacturing in terms of lightweight and cost-effectiveness

According to the editor’s understanding, dual injection technology is an advanced injection system. It consists of a single mold clamping mechanism and two parallel-arranged injection systems. This innovative technology effectively solves a series of manufacturing challenges caused by the maximum filling distance. Its launch not only represents a technological breakthrough, but also demonstrates the industry's unremitting efforts in pursuing higher efficiency and better performance

With the continuous increase in tonnage in the die-casting field and the improvement of integrated die-casting integration, we A significant increase in die casting volume can be observed. The traditional single-injection system is facing more and more restrictions, especially in the context of promoting advanced concepts such as integrated die-casting of vehicle chassis and skateboard chassis. For the injection process, these developments bring higher requirements and greater challenges. Against this background, the close cooperation between Lijin Group and Chery Automobile gave birth to this over-10,000-ton dual-injection system, which not only successfully solved related problems, but also opened up new possibilities for larger-scale integrated die-casting in the future.

Integrated die-casting technology is a method of integrated design of parts and molding them in one go using a large die-casting machine. Because of its advantages in improving stiffness, reducing mass, improving efficiency and It has attracted much attention due to its huge advantages in cost reduction. Chery Automobile's die-casting team has made some achievements in this regard. They not only completed the pre-research work on the A00 one-piece die-cast lower body platform, but also successfully studied the dual-injection process and verified the feasibility of the 800T dual-injection reduction mold. . These achievements not only prove the progress of technology, but also point the way for the future development of the entire industry
