Domestic Substitution of Core Components: Breaking Import Dependence to Build a Solid Barrier for Supply Chain Security

As a key pillar for the upgrading of the pulp molding industry, the long-standing high dependence on imports of core basic components has become a major bottleneck restricting the industry's practice of the "paper instead of plastic" policy, improvement of environmental protection capacity, and guarantee of supply chain security. With the deepening of the global plastic ban and the support of domestic environmental protection policies, the pulp molding industry has ushered in explosive growth. The domestic market scale reached 19.147 billion yuan in 2022, but the core components of high-end production equipment have long been monopolized by international giants such as Huhtamaki from Finland. "Made in China 2025" clearly proposes to strengthen industrial basic capabilities and promote the independent controllability of core components. Under the guidance of this policy, the domestic substitution process of the pulp molding industry has accelerated into a critical breakthrough period in 2026, continuously breaking foreign monopolies in key fields such as servo actuators, precision molds, and industrial control systems, and building a safe and stable industrial chain system for the green upgrading of the industry.

The breakthrough in the localization of servo actuators has provided core support for the intelligent upgrading of pulp molding equipment. The hot pressing and drying link of pulp molding has extremely high requirements for pressure and displacement control accuracy. Traditional hydraulic drive equipment has the pain points of slow response, oil leakage pollution, and high energy consumption, while imported servo actuators are expensive. The localization rate of servo hot pressing actuators has rapidly increased from 35% in 2023 to 58% in 2025, and has maintained a growth trend in 2026. Through industry-university-research collaborative research, domestic enterprises have independently developed electro-hydraulic composite control systems and integrated servo systems. Compared with imported products, the energy consumption has been further reduced by 28%, which can accurately control the clamping force of 20-780kN, adapting to the diverse production needs of pulp molding from food packaging to electronic buffer parts. With the advantages of high efficiency, energy saving, environmental protection and no leakage, it has successfully entered the export production lines of leading enterprises such as Jinsheng Environmental Protection and Huilin Packaging, breaking the technical barrier of overseas brands in the field of high-end servos.

The technology of precision ceramic molds has achieved leapfrog development, accurately solving the pain point of mold loss in the pulp molding industry. In pulp molding production, molds directly determine the forming accuracy and surface quality of products. Traditional metal molds are susceptible to acid-base corrosion by pulp, wear quickly, and need frequent replacement, which seriously affects production efficiency. Domestic enterprises have conquered high-performance ceramic material sintering and precision processing technologies, making the service life of precision ceramic molds suitable for pulp molding exceed 500,000 times, reaching the advanced level of international similar products. This effectively solves the industry problem of frequent replacement of traditional molds, shortens the equipment changeover time to 45 minutes, and greatly improves the continuous production efficiency. Driven by the downstream demand such as new energy vehicle packaging and food environmental protection packaging, the market scale of China's special ceramic molds for pulp molding has grown steadily in 2025. The import dependence of domestic products has dropped from 45% in 2018 to 32%. Enterprises such as Sanhuan Group have realized mass production of 0.5-micron-level precision ceramic molds, adapting to the processing needs of high-end electronic pulp molding products.

In the field of industrial control systems, domestic PLCs have gradually replaced imported brands, empowering the integrated operation of pulp molding equipment. The entire process of pulp molding forming, drying and shaping requires multi-parameter closed-loop control. Previously, it has long relied on overseas brand PLCs such as Siemens and Mitsubishi, which not only have high software authorization costs, but also their adaptability is difficult to match the customized production needs of domestic enterprises. Enterprises such as Chongqing Langwei and Inovance Technology have launched independent PLC products integrated with PID algorithms, which can real-time monitor mold cavity temperature, pressure and displacement, accurately control the linkage process of vacuum adsorption forming and hot pressing drying, and perfectly adapt to the double-station cycle production mode of pulp molding. After adopting the domestic PLC system, the software authorization cost of a single set of equipment can be saved by 300,000 yuan, and the comprehensive cost can be reduced by 120,000 to 150,000 yuan. In 2025, the localization rate of domestic PLCs in the pulp molding industry has increased to 48%, which is widely used in the intelligent production lines of leading enterprises, helping the industry reduce costs and increase efficiency.

The localization of core components continues to release industrial dividends for the pulp molding industry, promoting the comprehensive upgrading of the competitiveness of domestic equipment and products. Localization not only shortens the equipment delivery cycle and reduces manufacturing costs, but also improves the cost-performance advantage of domestic pulp molding equipment, driving the upgrading of industry capacity and export growth. In 2025, the export volume of domestic pulp molding equipment reached 680 million US dollars, an increase of 223.8% compared with 2021, helping domestic products be exported to European, American, Southeast Asian and other markets. Currently, the industry penetration rate is only 4%, with broad substitution space. In the future, it is necessary to continuously strengthen R&D investment, conquer the remaining technical gaps such as raw material purity and process stability, link the localization of upstream materials such as bio-based fibers, and build a solid barrier for the supply chain security of the pulp molding industry with the independence of core components, providing strong support for the industry to seize the global "paper instead of plastic" market share and achieve high-quality development.
