What is the current level of the company's integrated die-casting technology in the industry? Compared with Guangdong Hongtu and Quanfeng Automobile, what are the advantages? What designated projects have been obtained so far?

Wencan Holdings: Dear investors, hello! First of all, the company has continuously developed and improved high vacuum die-casting technology, mold technology used in high vacuum die-casting, special material development or preparation technology and related production process technology for many years, and has accumulated rich technology and experience for lightweight body structural parts. The body structural parts series developed and mass-produced by the company are relatively complete and comprehensive, involving door frames, front and rear beams and side beams, front and rear shock towers, torsion boxes, torsion box brackets, A-pillars, D-pillars, etc., and has successively supplied aluminum alloy body structural parts in batches to Mercedes-Benz, Tesla, Weilai, Xiaopeng, GAC AION, etc., forming a first-mover advantage in the lightweighting of aluminum alloy die-casting body structural parts. Body structural parts products contain a lot of "know-how" and have high technical barriers. On this basis, in order to promote the development of the company's large-scale integrated body structural parts products, the company began to develop large-scale integrated body structural parts products from the second half of 2020 in terms of materials, molds, equipment and other aspects. In order to give full play to the advantages of their respective business fields and establish a long-term strategic cooperative relationship, the company and the die-casting machine supplier Li Jin Group signed a "Strategic Cooperation Agreement" in May 2021. Through the sharing of resources between the two parties, they jointly provide integrated casting product solutions for downstream customers. The company is at the forefront of the industry in the field of integrated body structural parts products and leads the development of the industry. For specific business conditions, please refer to the periodic reports disclosed by the company. Thank you for your attention!
