The domestic casting mold industry has achieved a major breakthrough. Leading enterprises in the industry, relying on their technological R&D and innovation capabilities, have realized technological upgrades for four core mold categories: Die Casting Die, Gravity Die Casting Mold, Hot Stamping Die, and Low-Pressure Die Casting Mold. At the same time, they have optimized the supporting production system of Patterns for Molding Line and Core Boxes, comprehensively meeting the precision production needs of automotive lightweighting, high-end equipment manufacturing and other fields, and injecting strong momentum into the high-quality development of the industry.
With the global manufacturing industry moving towards precision, greenization and intelligence, downstream industries such as automotive, aerospace and new energy have put forward higher requirements for the precision, efficiency and stability of casting molds. The upgrade plan launched by the enterprise this time covers key equipment throughout the casting production process. Among them, the Die Casting Die has been optimized for the demand of ultra-large integrated die casting, drawing on the technical experience of 10,000-ton double-injection die casting molds, improving the pressure resistance and filling efficiency of the mold. It can be adapted to 10,000T-level die casting production lines, effectively solving the industry problem of limited filling distance for large structural parts, and helping the integrated production of vehicle chassis and body structural parts.
In the segmented field of casting technology, both Gravity Die Casting Mold and Low-Pressure Die Casting Mold have achieved two-way upgrades. The Gravity Die Casting Mold adopts new heat-resistant materials and precise temperature control design, reducing the defect rate of casting pores, shrinkage holes and other defects, adapting to the casting needs of various materials such as aluminum and magnesium alloys, and being widely used in the production of auto parts, general machinery and other products. The Low-Pressure Die Casting Mold has optimized the pressure control system to achieve stable filling of molten metal. Combined with conformal cooling technology, it has greatly improved the density and dimensional accuracy of castings, which can meet the precision casting standards of high-end aluminum alloy wheels and aerospace parts, echoing the development trend of the magnesium alloy lightweight industry.
As the core equipment for the production of automotive ultra-high-strength steel parts, the Hot Stamping Die has focused on breaking through the technical bottleneck of the cooling system in this upgrade. Through the optimization of the casting process, the prefabricated cooling pipes are integrally cast with the mold, realizing the conformal fit between the cooling system and the mold cavity, increasing the casting quenching cooling rate to more than 65℃/s, which is far higher than the martensitic critical cooling requirement. It effectively ensures the mechanical properties of ultra-high-strength steel parts, helps the dual improvement of automotive lightweighting and safety performance, and provides core technical support for the lightweighting of new energy vehicle bodies.
In addition to the core mold categories, the enterprise has simultaneously improved the supporting R&D and production of Patterns for Molding Line and Core Boxes. The Patterns for Molding Line has launched a variety of adaptation schemes, covering various styles such as integral molds, split molds and shell molds, which can accurately match the needs of molding lines according to casting batches and casting sizes. It adopts wear-resistant materials to improve service life and reduce the production cost of the molding process. The Core Boxes have optimized the cavity design and demoulding structure, combined with precision processing technology, to ensure the dimensional accuracy and surface quality of sand cores, reduce the impact of sand core defects on casting quality, form a synergistic effect with the four core molds, and build a full-process casting equipment solution, echoing the growth trend and technical needs of the global casting mold market.
According to industry data, the global casting mold market is expected to grow from 19.235 billion US dollars in 2025 to 28.747 billion US dollars in 2035, with a compound annual growth rate of 4.1%. Among them, aluminum-magnesium alloy molds and automotive applications dominate. The full-category technological upgrade of the enterprise this time not only fills some technical gaps in domestic high-end casting molds, improves the market competitiveness of domestic molds, but also promotes the integration of core products such as Die Casting Die and Hot Stamping Die with the international advanced level, helping China transform from a casting power to a casting strong country.
Relevant person in charge said that in the future, they will continue to focus on the needs of downstream industries, increase investment in technological R&D, promote the upgrading of mold products towards intelligence and customization, further optimize the performance of supporting products such as Patterns for Molding Line and Core Boxes, deepen collaborative innovation with upstream and downstream enterprises, provide more competitive casting mold solutions for automotive lightweighting, high-end equipment manufacturing and other fields, and promote the high-quality development of the entire casting mold industry.
