Shenhua Printing Plate Knife Pad: Technological Iteration and Innovation Breakthrough Driven by Industry-University-Research Collaboration

The performance upgrade of the knife plate spring pad cannot be achieved without the support of materials science. Shenhua Printing Materials is well aware of the core value of industry-university-research cooperation for technological innovation. By establishing deep cooperative relationships with multiple domestic universities' materials science and engineering colleges, it has constructed a complete innovation chain of "basic research - technology transformation - product application", promoting the continuous iterative upgrade of the knife plate spring pad products.

In terms of the cooperation model, Shenhua Printing Materials collaborates with universities to establish a joint laboratory for die-cutting elastic materials. The laboratory is equipped with advanced material characterization equipment and performance testing instruments. The university research teams focus on the basic formula research and molecular structure optimization of elastic materials, while the engineers of Shenhua Printing Materials are responsible for converting the research results of the laboratory into products that meet the actual needs of the die-cutting industry. This "university research + enterprise transformation" model not only solves the problem of the separation of university research results from the market, but also provides Shenhua Printing Materials with continuous technical reserves.

In terms of specific research achievements, the joint laboratory has developed nano-composite elastic materials to address the industry technical problem of "inability to achieve high rebound and high wear resistance simultaneously". This material enhances the wear resistance of the material while not sacrificing its rebound performance by adding nano-sized ceramic particles to the rubber matrix. After testing, the deephua printing materials knife plate spring pad using nano-composite elastic materials has a 30% improvement in wear resistance compared to traditional materials, and the rebound rate still remains above 95%, perfectly solving the industry pain points. In addition, the joint laboratory has also developed degradable elastic materials. This material is mainly made of biobased rubber and can be naturally degraded after use, conforming to the global green development trend. It has now been mass-produced and applied to deephua printing materials' environmentally friendly knife plate spring pad products.

In terms of the efficiency of成果转化， the joint laboratory has established a rapid transformation mechanism. For formulations that are feasible after laboratory verification， Shenhua Printing Materials can complete pilot production and mass production within 1-2 months， ensuring that new technologies can respond quickly to market demands. As of now， the two parties have applied for 12 patents related to elastic materials， including 5 invention patents. These patent technologies have all been applied to deephua printing materials' knife plate spring pad products， becoming an important part of the enterprise's core competitiveness.
