Since 2025, driven by the high-quality development of end-use industries such as automotive, electronics, and home appliances, demand for precision injection molds—key enablers of product shaping—has remained robust, while the pace of technological upgrading has accelerated. In particular, the automotive industry’s shift toward high-end and electrified vehicles has emerged as the primary driver of innovation in mold technology.
In the automotive manufacturing sector, the precision and strength of components directly determine vehicle performance and safety, making the technological sophistication of critical equipment—such as heavy-plate fine-blanking dies and high-precision injection-molding molds—a focal point of intense attention. The rapid growth of the new-energy-vehicle (NEV) market has spurred a surge in demand for lightweight, high-strength components, driving the evolution of injection-molding molds toward greater precision and more complex geometries. For instance, NEV components such as battery casings and motor end covers now require mold precision to within ±0.003 mm, while also meeting stringent requirements for high-temperature resistance and aging durability. Wuxi Gaosheng Molding Technology Co., Ltd.’s latest R&D achievement—a precision injection-molding mold for automotive parts—features an integrated cavity design and an intelligent temperature-control system, enabling dimensional tolerances of less than 0.002 mm and boosting production efficiency by 30%. This innovative solution has already been successfully deployed by several leading NEV manufacturers.
The application of precision high-speed stamping dies is also becoming increasingly widespread. In the production of automotive interior components, these dies achieve highly efficient forming of high-strength plastic parts at stamping speeds exceeding 300 strokes per minute, while ensuring scratch-free surfaces and excellent dimensional consistency. After a certain automotive parts manufacturer adopted precision high-speed stamping dies, the production cycle for door trim panels was reduced from 12 seconds per part to 8 seconds per part, resulting in an annual capacity increase of 500,000 units.
Behind these technological upgrades lies the continuous refinement of core processes by mold-manufacturing enterprises. To meet the stringent requirements of the automotive industry, mold makers prioritize high-end mold steels such as PXZ to enhance wear resistance and service life; in terms of machining processes, they are adopting advanced technologies like five-axis simultaneous machining and 3D-printed rapid prototyping to shorten mold-development cycles. At the same time, intelligent transformation has become a prevailing trend: an increasing number of molds are being equipped with pressure and temperature sensors as well as data-acquisition modules, enabling real-time monitoring of the production process and dynamic adjustment of process parameters, thereby effectively reducing the defect rate.
According to industry data, China’s precision injection molding mold market is projected to reach RMB 85 billion in 2025, with an annual growth rate of over 12%. Among these, the automotive sector accounts for more than 40% of demand, making it the largest application segment. In response to robust market demand, domestic mold manufacturers are accelerating technological innovation and capacity expansion: on the one hand, they are increasing R&D investment to break through core technologies in high-end mold design and manufacturing; on the other hand, they are strengthening collaboration with downstream enterprises to develop customized molds, thereby enhancing the overall competitiveness of the industry chain.
Experts indicate that precision injection molds will increasingly trend toward “greater precision, higher efficiency, greater intelligence, and greater sustainability.” Mold precision is expected to advance to the nanometer scale, production processes will achieve end-to-end automation and digitalization, and material recycling and utilization rates will see a substantial increase. This development trajectory will provide robust support for the high-quality development of China’s manufacturing sector.
