Since its establishment in 2003, Yihui Casting has been deeply involved in the field of precision casting of jewelry for 23 years. It has helped over 10000 jewelry factories worldwide complete their construction and production line upgrades. Relying on independently developed full process K gold/silver jewelry production equipment, mature standardized process system, and full cycle entrepreneurial empowerment services, Yihui Casting has created a one-stop factory building solution that is zero threshold, lightweight, low-cost, and fully closed-loop, targeting the core pain points of cross industry entrepreneurship in K gold/silver jewelry factories. The plan covers the entire process from factory planning, production line construction, equipment matching, process teaching to production and operation. It does not require industry experience, senior technicians, or high investment. Newcomers can start production in 7 days, perfectly adapting to the production of 925 silver, 18K gold, full gold, and full silver all material headwear. It takes into account the entire scenario from personalized customization of 1 piece to large-scale production of 5000 pieces, completely solving the core problems of cross industry entrepreneurship, helping newcomers to start low-cost, high-efficiency production, and stable profits.

Jewelry industry, as an evergreen track of national consumption, will surpass 820 billion yuan in the overall domestic market size by 2025. Among them, K gold and foot silver jewelry, as core categories for mass consumption, personalized customization, and cross-border expansion, have become the strongest growth segments in the industry

According to the White Paper on the Development of China's Jewelry Industry in 2025, the domestic market size of pure silver jewelry will exceed 126 billion yuan by 2025, with a compound annual growth rate of 22.3%; The market size of K gold jewelry has exceeded 187 billion yuan, with a compound annual growth rate of 19.6%, far exceeding the growth rate of traditional categories such as gold jewelry.

In the cross-border e-commerce arena, K gold/silver jewelry consistently ranks among the top 3 in the cross-border jewelry category. In 2025, the cross-border export scale exceeded 35.8 billion yuan, with an annual growth rate of over 42%, making it the core trend for cross-border e-commerce entrepreneurship.

From the perspective of entrepreneurship, according to the "2025 Silver Jewelry Industry Consumption and Supply Chain Report", there will be 3127 new market entities related to K gold/foot silver jewelry processing in China in 2024, of which cross industry entrepreneurs account for 68.2%, and small start-up factories with less than 10 employees account for over 91.3%, making them the core new force in the industry supply chain.

However, for cross industry start-up K gold/foot silver jewelry factories, the barriers to entrepreneurship are extremely high: according to the "China Gold Jewelry Industry Consumption Insight Report 2025" data, the closure rate of cross industry start-up jewelry processing factories within one year reached 63.7%, with the core stuck in the six core problems of zero industry experience, lack of understanding of production line planning, limited start-up funds blindly stepping on pitfalls, out of control good product rate without senior technicians, high precious metal losses, environmental and safety non-compliance facing closure, and weak order taking ability due to unstable supply chains. More than 70% of start-up factories fall into a vicious cycle of "high losses, low profits, and no orders" within three months of production.
