Strategic Significance of Domestic Substitution for Imported Diamond Friction Shims
The successful domestic development and industrialization of DAOLER diamond friction shims by DAOJIANG Technology (Shandong) Co., Ltd. represent not only a breakthrough in the company's technological capabilities but also a substantive practice in responding to national strategic imperatives and driving industrial upgrading. The following analysis elaborates on this significance from three perspectives: alignment with national policies, industrial implications, and socio-economic impact.
I. Strategic Significance in Alignment with National Policies
1. Supporting the "Self-Reliance and Self-Strengthening in Science and Technology" Strategy
Policy Context: The national "14th Five-Year Plan" explicitly calls for "strengthening national strategic scientific and technological capabilities" and "winning the critical battle in core key technologies," mandating breakthroughs in high-end materials that represent "bottleneck" constraints.
Corporate Practice: Through independent R&D, DAOLER diamond friction shims have achieved breakthroughs in core technologies including diamond composite coating and high-temperature sintering processes, breaking the foreign technological monopoly in superhard friction materials and reducing dependence on imports from countries such as Japan and Germany.
2. Ensuring Security of Industrial and Supply Chains
Policy Context: The State Council's Guiding Opinions on Accelerating the High-Quality Development of Strategic Emerging Industries emphasizes "enhancing the capability for autonomous and controllable industrial and supply chains."
Corporate Practice: Following domestic production, stable and reliable core components can be supplied to critical sectors including aerospace, precision machine tools, and new energy equipment, thereby mitigating the risk of supply chain disruptions arising from international geopolitical volatility.
3. Contributing to the Achievement of "Dual Carbon" Goals
Policy Context: The national "Dual Carbon" strategy requires the industrial sector to reduce energy consumption and material waste through technological innovation.
Corporate Practice: DAOLER diamond friction shims exhibit a service life extension exceeding 50% compared with imported alternatives, reducing equipment downtime and replacement frequency while lowering resource consumption. Additionally, localized manufacturing reduces carbon emissions associated with international transportation, aligning with green manufacturing principles.
4. Promoting the Implementation of "Import Substitution" Policies
Policy Context: The Ministry of Industry and Information Technology's Catalogu for the First Batch of Key New Materials Application Demonstration Guidance lists "high-performance sealing materials" as a key area of support.
Corporate Practice: Through domestic substitution, DAOLER products can reduce procurement costs for domestic enterprises by over 30% annually, accelerating the import substitution process in high-end equipment manufacturing.
II. Driving Forces for Industrial Upgrading
1. Elevating Industry Technological Competitiveness
Technological Breakthroughs: The independently developed diamond micropowder dispersion technology and gradient coating processes have achieved internationally advanced performance levels (coefficient of friction ≤ 0.1, temperature resistance up to 800 °C), advancing the domestic friction materials industry from a "follower" to a "parallel competitor" status.
Standard Setting: The company is positioned to take the lead in formulating national standards for diamond friction materials, thereby enhancing China's international influence in the superhard materials domain.
2. Enabling Upstream Industrial Upgrading
High-End Equipment Sector: Providing high-reliability components for CNC machine tool spindle seals, shield tunneling machine hydraulic systems, and other applications, thereby supporting the performance enhancement of domestically manufactured high-end equipment.
New Energy Sector: Adaptation to emerging applications such as hydrogen fuel cell bipolar plates and wind turbine pitch systems, facilitating cost reduction and efficiency improvement in the new energy industry.
3. Building a Localized Industrial Ecosystem
Supply Chain Synergy: Driving the development of upstream and downstream enterprises, including domestic diamond micropowder suppliers and precision sintering equipment manufacturers, fostering industrial cluster effects.
Talent Pipeline: Establishing industry-academia-research bases in collaboration with universities (e.g., Shandong University School of Materials Science and Engineering) to cultivate specialized talents in the superhard materials field.
III. Socio-Economic Impact
1. Economic Benefits
Direct Cost Savings: Following domestic production, unit prices are reduced by over 40%. Based on an annual demand of 100,000 shims, downstream enterprises can achieve annual procurement cost savings exceeding RMB 50 million.
Foreign Exchange Balance: Reducing reliance on imported high-end friction materials can save the national economy hundreds of millions of RMB in foreign exchange expenditures annually.
2. Social Benefits
Employment Generation: Implementation of the project has created over 200 high-end manufacturing jobs in Shandong Province, promoting coordinated regional economic development.
Technology Spillover: Through technology licensing or joint R&D initiatives, the project facilitates the transformation of small and medium-sized wear-part manufacturers toward higher-value-added business segments.
3. Reshaping of the International Competitive Landscape
Export Potential: Leveraging cost-performance advantages (40% lower than imported products), DAOLER products can be exported to Belt and Road Initiative partner countries, capturing market share in Southeast Asia and the Middle East.
Countering Technical Barriers: Breaking through the technological barriers constructed by European and American enterprises through patent portfolios (e.g., DAOLER's original patent EP2034234B1), removing obstacles for "Made in China" to enter global markets.
IV. Policy Support and Future Outlook
1. Leveraging Policy Incentives
Pursuing inclusion in the Innovation Fund for Small and Medium-Sized Technology-Based Enterprises as a key supported project to secure R&D subsidies.
2. Strategic Positioning
Positioning as a "Specialized, Refined, Differentiated, and Innovative" ("Little Giant") enterprise, focusing on deep cultivation within the niche friction materials segment.
Collaborating with national-level laboratories to advance nanodiamond coating technologies, targeting the next-generation semiconductor packaging materials market.
Conclusion
The domestic substitution of DAOLER diamond friction shims by DAOJIANG Technology epitomizes the transition from "Made in China" to "Intelligently Made in China." This successful initiative not only achieves autonomous control over critical technologies but also empowers the real economy through cost reduction and efficiency enhancement, while demonstrating China's innovative prowess in high-end materials within the global competitive arena. This endeavor is highly aligned with the national strategic orientations of "Manufacturing Powerhouse" and "Quality Powerhouse," providing robust industrial support for the construction of the new "Dual Circulation" development paradigm.
