Shen Hua: Special knife holder and indentation strips for precision electronics/tag die-cutting, providing ultra-thin precision to upgrade small-scale die-cutting operations

The precision electronics / label die-cutting field (electronic labels, self-adhesive labels, precision electronic auxiliary materials, medical labels), the core requirements for die-cutting processes focus on ultra-thin precision, anti-static, clean without dust, and precise indentation. The die-cutting components such as the die-cutting spring pad and indentation strip are the core consumables in the die-cutting process and need to be adapted to the die-cutting requirements of small-sized and precise structures - the die-cutting spring pad needs to be ultra-thin, high rebound, and anti-static to avoid static adsorption, pad displacement, and ensure die-cutting accuracy; the indentation strip needs to be ultra-thin and precise to meet the indentation requirements of small-sized labels, prevent indentation that is too deep, too shallow or offset, and at the same time be clean without dust to avoid contaminating electronic auxiliary materials and labels. Shenhua has been deeply engaged in the foam and die-cutting consumables field for 22 years, accurately understanding the pain points of the precision electronics / label die-cutting industry, focusing on the specialized research and customization of die-cutting spring pads and indentation strips, with "ultra-thin precision, anti-static, clean long-term" as the core, creating dedicated die-cutting consumables solutions for precision electronics / labels, becoming the core supporting partner of many leading electronic label and precision electronics enterprises, and enabling the high-end and precision upgrade of the small-sized die-cutting industry.

Precise attack, solving the core pain points of precision small-scale die-cutting 

Shen Hua, through its deep involvement in the fields of precision electronics and label die-cutting, has discovered that the industry generally faces four core pain points, and the requirements for the precision and cleanliness of consumables are far higher than those in ordinary die-cutting scenarios: Firstly, the die-cutting dimensions are very small and the structure is very precise. Traditional die-cutting templates have thick spring pads and insufficient forming accuracy, which can easily cause displacement, uneven elasticity, resulting in die-cutting deviations and inability to meet the requirements for small-sized products; Secondly, electronic labels and precision electronic auxiliary materials are sensitive to static electricity. Traditional die-cutting templates have no anti-static performance, which can easily cause static adsorption of dust, labels or electronic auxiliary materials, affecting product quality; Thirdly, the requirements for indentation are very precise. The indentation lines of small-sized labels are very fine. Traditional indentation strips have insufficient precision and uneven thickness, which can easily cause indentation that is too deep, too shallow or offset, resulting in the failure of label folding; Fourthly, precision electronic and medical labels have extremely high cleanliness requirements. Traditional consumables are prone to powder shedding and dust generation, polluting the products and not meeting the industry's cleanliness standards. Based on 22 years of accumulated expertise in precision foam sheet forming technology, Shen Hua has established a specialized research and development team for precision micro-cutting consumables, and has collaborated with electronic label enterprises, precision electronic manufacturers, and research institutions to conduct joint research, overcoming core technologies such as ultra-thin precision forming, anti-static, clean without dust, and micro-sized compatibility. 

For the past 22 years, the deephua knife plate elastic pad and indentation strip technology has continuously evolved, aligning with the development trends of the precise electronic/label die-cutting industry: In 2020, a series of ultra-thin knife plate elastic pads specifically for precise electronic/label applications was launched, with a thickness as thin as 0.1mm and a size accuracy controlled within ±0.01mm, suitable for small-sized die-cutting requirements; In 2022, a long-lasting anti-static formula was developed, and an anti-static knife plate elastic pad and indentation strip series was launched, with precise surface resistance control and effective prevention of static adsorption, while achieving a clean and dust-free environment, in line with the clean standards of the electronic and medical industries; In 2023, the ultra-thin precision forming technology was optimized, with the rebound rate of the knife plate elastic pad increasing to over 90%, and the precision of the indentation strip reaching ±0.02mm, suitable for more precise small-sized die-cutting requirements; In 2024, all product series passed special certifications for the electronic and medical industries, and were批量 applied in electronic labels， self-adhesive labels， precision electronic auxiliary materials， medical labels， etc.， serving over 40 leading electronic and label enterprises， with die-cutting accuracy improved to ±0.01mm， product qualification rate improved to over 99.8%， completely solving the problems of static， dust， and insufficient precision.
