Dalian Bohai has successfully helped a foreign-invested enterprise achieve domestic substitution for critical rubber components. “We used to worry constantly about being ‘choked’—now we feel much more at ease,” said the company’s procurement manager.
1. Dilemma: The wear-resistant vital point that’s “locked” in place.
For a long time, in fields such as heavy-duty construction machinery, mining equipment, and high-end conveying systems, high-performance, wear-resistant rubber components have been crucial for ensuring the long-term, high-intensity, and stable operation of these devices.
These components often have to withstand continuous friction, impact, and harsh environmental conditions, and their service life directly determines the maintenance cycle and operating costs of the equipment. However, the core formulations and processes for specialized compounded elastomers have long been mastered by a small number of international chemical giants.
“It’s not that we don’t want to use domestically produced materials—it’s that we don’t dare,” a mechanical engineer confessed. “Although imported rubber compounds are expensive and have long lead times, their performance is stable. While domestic alternatives may come close in laboratory data, once they’re put into real-world operating conditions—especially when it comes to comprehensive performance characteristics like wear resistance, tear resistance, and heat generation control—they tend to fall short, often leading to premature equipment failure and posing far too great a risk.”
This “poor performance reliability” leaves many manufacturing companies in a dilemma: either bear the high costs of imports and supply-chain risks, or put up with uncertain product quality.
2. Landing: The Path to Domestication—From Data to Trust
“The value of technological breakthroughs ultimately lies in their impact on customers’ production lines. The lab’s test reports are merely ‘admission tickets’—the real ‘exam venue’ is the actual operating conditions in customers’ production workshops and equipment,” said the project leader.
To bridge the trust gap—from “meeting data standards” to “reliable application,” the technology team engaged in deep collaboration with the customer:
3. Looking ahead: Beyond a future of mere substitution.
The successful application of domestically produced high-performance compounded rubber goes far beyond simply replacing imports and reducing costs.
It first enhances the self-reliance and controllability of supply chains in key industries. From construction machinery to rail transit, from port equipment to specialized vehicles, more enterprises are able to break free from their reliance on single overseas suppliers and build supply chain systems that are both safer and more agile.
On a deeper level, it ushers in a new model of collaborative innovation with automakers. Material suppliers are no longer merely passive providers of standard components; instead, they can gain a deep understanding of automakers’ needs, participate in front-end design, and become partners who jointly define component performance.
