In the current era of rapid iteration of 3C digital products, heat dissipation performance has become an important indicator for measuring the quality of devices such as mobile phones and laptops. As a well-known domestic supplier of 3C accessories, Xunke Precision Technology Co., Ltd. has successfully overcome technical bottlenecks by introducing pneumatic punching machines in the production of mobile phone heat sinks, seizing market opportunities with higher production efficiency and product accuracy. Its experience provides new ideas for industry transformation and upgrading. ?
1、 Production dilemma: Traditional craftsmanship cannot meet the strict standards of the 3C industry
Xunke Precision mainly provides heat sinks for major mobile phone brands. With the increasing trend of lightweight smartphones, the thickness of heat sinks has gradually decreased from 0.3mm to 0.15mm, and there are extremely high requirements for surface flatness and heat dissipation hole accuracy. However, the ordinary mechanical punching machines originally used by the enterprise have obvious shortcomings: the punching speed is slow, only 60 times per minute, which is difficult to match the short delivery cycle needs of mobile phone manufacturers; During stamping, metal sheets are prone to deformation, resulting in a deviation of over ± 0.05mm in the position of heat dissipation holes and a scrap rate of up to 20%; At the same time, the stability of the equipment is poor, and there are frequent problems such as mold wear and uneven punching pressure. The monthly downtime caused by equipment failures can reach up to 30 hours, seriously affecting production progress and customer cooperation relationships. ?
2、 Technological Innovation: Pneumatic Punching Machine Accurately Empowers Production Upgrade
To address the aforementioned challenges, Xunke Precision has conducted extensive research and introduced the SP-600 high-speed precision pneumatic punch press. This device is customized for the precision stamping needs of 3C products, equipped with an ultra high speed pneumatic servo system, with a stamping frequency of up to 200 times per minute, greatly improving production efficiency; By adopting a nanometer level precision mold positioning system and pressure closed-loop control technology, the stamping accuracy is improved to ± 0.01mm. Even ultra-thin heat sinks with a thickness of 0.15mm can maintain a smooth surface and precise heat dissipation holes; The equipment is also equipped with an intelligent fault warning system, which can monitor mold wear, abnormal air pressure and other situations in real time, issue warnings in advance and automatically shut down, reducing the downtime caused by equipment failures. In addition, the rapid mold changing device of the pneumatic punch press supports quick switching of various specifications of molds, meeting the production needs of different models of mobile phone heat sinks. ?
3、 Significant Results: Achieving Leapfrog Growth in Production Efficiency
After the pneumatic punch press was put into use, Xunke Precision's heat sink production line underwent a comprehensive upgrade:
Significant improvement in production efficiency: The monthly output of a single production line has increased from 80000 pieces to 200000 pieces, and the delivery cycle has been shortened by 50%. We have successfully won long-term orders from multiple leading mobile phone manufacturers; ?
Significant optimization of product quality: The scrap rate has been reduced from 20% to within 3%, and the heat sink has passed strict customer quality inspection standards, resulting in an increase in customer satisfaction to 98%; ?
Cost effective reduction: Equipment energy consumption is reduced by 35% compared to traditional mechanical punching machines, saving approximately 400000 yuan in electricity costs annually; Due to a reduction in equipment failures and a decrease in scrap rates, the annual comprehensive cost has been reduced by over 2 million yuan. ?
4、 Industry Insights: Intelligent Devices Drive 3C Manufacturing to New Heights
The transformation practice of Xunke Precision fully proves that in the field of 3C digital product manufacturing, pneumatic punching machines, with their high-speed, precision, and intelligent characteristics, can effectively solve the production pain points of enterprises and help them stand out in the fierce market competition. With the continuous development of 5G and AI technologies, the precision and production efficiency requirements for accessories in 3C products will continue to increase. Intelligent equipment such as pneumatic punching machines will become a key force in promoting the high-quality development of the 3C manufacturing industry.
