Shenhua Printing Material Knife Plate Spring Pad: Special High-Precision Anti-Clogging Solution for Packaging and Cutting of Small Parts

Packaging of small components (such as electronic micro-components, precision metal small parts, and miniature jewelry packaging) has the characteristics of small size of components, high packaging precision requirements, and easy jamming. During die-cutting, it is necessary to ensure that the packaging cut edges are neat and the dimensions are precise, avoiding jamming that causes production interruptions. Conventional spring clips have insufficient precision and poor waste discharge, prone to problems such as cut edge burrs, size deviations, and waste blockage, making it difficult to meet the strict requirements of micro-component packaging. Shenhua Printing Materials focuses on the pain points of micro-component packaging and creates high-precision anti-jamming special knife plate spring clips to achieve efficient and precise die-cutting of micro-component packaging.

In terms of precision optimization, a nano-level high-precision forming process is adopted, with the thickness error of the spring clip controlled within ±0.01mm, and the hardness fluctuation of the same plate ≤1 Shore A, ensuring precise die-cutting dimensions, and meeting the fine knife line requirements of micro-component packaging (knife line width ≤0.5mm); a high-density homogeneous base material is selected, with an elastic recovery rate of over 98% and a compression permanent deformation rate of ≤2%, ensuring uniform pressure transmission and avoiding excessive pressure causing cut edge burrs, size deviations, and waste blockage, achieving neat and smooth cut edges.

In terms of anti-jamming and waste discharge design, the surface of the spring clip is coated with a special low-friction anti-sticking coating, with the friction coefficient reduced to below 0.06, reducing the adhesion of waste materials to the spring clip, and adding micro-sized waste discharge guide patterns to guide the rapid discharge of small waste materials, avoiding production interruptions caused by jamming; a 0.3-0.8mm ultra-thin spring clip is launched, suitable for thin materials of micro-component packaging (such as thin PET film, PP film), avoiding material stretching deformation, ensuring precise packaging dimensions. After an electronic micro-component packaging enterprise applied this solution, the defective rate of micro-component packaging die-cutting decreased from 8% to 0.2%, the frequency of jamming-induced production interruptions reduced by 90%, production efficiency increased by 35%, and it fully met the strict requirements of micro-component packaging.
