Shen Hua: Special knife holder for precision electronic die-cutting, equipped with ultra-thin anti-static technology to upgrade precision production.
The precision electronic die-cutting field (electronic accessories, mobile phone accessories, RFID labels, medical electronic components) focuses on ultra-thin precision, long-lasting anti-static, clean without dust, and precise rebound. As the core precision consumable in the die-cutting process, the die-cutting tool spring pad needs to be compatible with small-sized and precise-structured die-cutting requirements, while also meeting the anti-static and high-cleanliness requirements of the electronics industry - it needs to be ultra-thin in shape, with controllable precision, avoiding static adsorption and dust pollution, protecting precision electronic components, and providing uniform rebound, avoiding die-cutting deviation and component damage, ensuring the precision and yield of precision electronic die-cutting. Shenhua has been deeply engaged in the field of foam and precision die-cutting consumables for 22 years, accurately understanding the pain points of the precision electronic die-cutting industry, focusing on the specialized research and customization of die-cutting tool spring pads, with "ultra-thin precision, anti-static, clean and long-lasting" as the core, creating a dedicated die-cutting tool spring pad solution for precision electronics die-cutting, becoming the core supporting partner for many leading electronics enterprises and medical electronics manufacturers, and enabling the upgrade of precision electronic production.
Precise attack, solving the core pain points of precision electronic die-cutting
Shen Hua, while deeply engaged in the field of precision electronic die-cutting, discovered that the industry generally faces four core pain points. The precision, anti-static performance and cleanliness requirements for the cutting tool plates are extremely strict: First, the dimensions of precision electronic die-cutting are very small and the structure is very precise. The minimum die-cutting size can reach 10mm×10mm. Traditional cutting tool plate spring pads have uneven thickness and insufficient precision, which easily cause die-cutting deviations and damage electronic components; Second, electronic components are extremely sensitive to static electricity. Traditional cutting tool plate spring pads have no long-term anti-static performance and are prone to generating static electricity, causing chips to be broken, attracting dust, and leading to the failure of electronic components; Third, precision electronic die-cutting requires a high-cleanliness environment. Traditional spring pads are prone to powder shedding and generating fine dust, which contaminates electronic components and die-cut substrates, affecting product quality; Fourth, electronic auxiliary materials are mostly in the form of films and thin sheets. Traditional spring pads have uneven rebound, which easily causes incomplete cutting, burrs, and deformation of the substrate, resulting in a low qualification rate of finished products.
Based on 22 years of accumulated expertise in precise foam molding and anti-static technology, Shenhua has established a specialized R&D team for precise electronic die-cutting blade cushioning. They collaborate with electronic enterprises and precision die-cutting equipment manufacturers to jointly develop and overcome core technologies such as ultra-thin precision molding, long-term anti-static performance, cleanliness without dust, and precise rebound. Over the past 22 years, the technology has continuously evolved: In 2020, a series of precision electronic-specific blade cushioning products were launched, with the minimum thickness of 0.08mm and a thickness tolerance of ±0.005mm, solving the problem of ultra-thin precision die-cutting; In 2022, a long-term anti-static and clean formula was developed, with a surface resistance stable at 10⁶ - 10⁹Ω, without dust shedding or dust, meeting the standards of electronic clean workshops; In 2023, the high-speed rebound structure was optimized, with the rebound response speed increased by 60%, suitable for ultra-high-speed precision die-cutting, eliminating the problems of incomplete cutting and burrs; In 2024, all product series passed special certifications for the electronics industry and were applied in batches to over 40 leading electronic and medical electronic enterprises in China, with the product qualification rate increasing to over 99.8%.
Core product matrix, suitable for all scenarios of precise electronic die-cutting
Shenhua focuses on meeting the comprehensive needs of precision electronic die-cutting. It has developed three series of dedicated die plate spring pads. Each product has undergone rigorous thickness accuracy testing, anti-static testing, and cleanliness testing to ensure it meets the high requirements of precision electronic die-cutting. "The precision electronic die plate spring pads of Shenhua have exceeded our expectations in terms of accuracy and anti-static effect. The ultra-thin model has uniform thickness and will not cause die-cutting deviations. Moreover, it is clean without dust and does not generate static electricity, which will not damage our precision electronic components. They remain stable even under ultra-high-speed production, significantly improving our production efficiency and yield." A senior research and development leader from a leading electronics company commented.
Electronic auxiliary material-specific knife pad spring clip: It features ultra-thin precision, precise rebound, and anti-adhesive properties. It uses a high-rebound polyurethane ultra-thin base material with a thickness ranging from 0.08mm to 1.0mm, with a thickness tolerance of ±0.005mm. It precisely controls the die-cutting depth, eliminating the problem of not being able to cut through or piercing the base material. The surface is treated with anti-adhesion, not adhering to glue or absorbing electronic auxiliary materials. It is suitable for precise die-cutting of electronic films, insulating sheets, heat-conducting sheets, etc. It has high rebound resistance and anti-fatigue properties. Under high-speed die-cutting, the rebound is stable, without burrs or base material stretching deformation, meeting the batch production requirements of electronic auxiliary materials.
