弹簧中的应力松弛是什么?它如何影响性能?
弹簧中的应力松弛是什么?它如何影响性能?

应力松弛是指弹簧在恒定变形下,其载荷或力随时间逐渐损失的现象。它是决定精密部件是在数月后失效,还是可靠运行数十年的隐藏因素。与疲劳(由循环载荷引起的突然断裂)不同,应力松弛会悄无声息地降低弹簧维持所需力的能力,导致连接松动、密封泄漏或电接触失效。对于为高温或长寿命应用选型弹簧的工程师而言,考虑应力松弛并非可有可无,而是...

薄型设备热管制造的最新趋势是什么?
薄型设备热管制造的最新趋势是什么?

当今热管制造的两大主导趋势是采用微沟槽吸液芯结构和超薄外形设计,这得益于智能手机、笔记本电脑和5G模块对高性能散热的需求。具体而言,现代微沟槽热管可实现超过20,000 W/m·K的导热系数,同时保持1.0毫米或更薄的厚度,这是传统烧结粉末吸液芯无法实现的。这一转变使工程师能够解决热密度问题(通常超过15 W/cm²)...

是什么推动了半导体设备零部件精密加工热潮?
是什么推动了半导体设备零部件精密加工热潮?

半导体设备零部件正经历精密加工热潮,因为芯片制造商要求更严格的公差、更硬的材料和更快的交付周期,以支持3nm和2nm等先进制程。这一热潮由气体分配环、静电吸盘和石英窗等关键部件的需求驱动,这些部件需要±5微米的公差和Ra 0.2 µm的表面光洁度。BQUQ拥有20年的CNC加工和金属冲压经验,正处于这一浪潮的中心,为蚀...

CFD仿真如何改变散热器设计的采用率?
CFD仿真如何改变散热器设计的采用率?

CFD仿真对于严肃的散热器工程来说已不再是可选项——在新型翅片散热器项目中,热设计团队的采用率已从2018年的约35%上升到2025年的超过78%。这一转变得益于物理样机成本降低40%,以及定制挤压和铲削翅片设计的上市时间加快60%。在本文中,我们量化了CFD采用对CNC加工、冲压和挤压散热器的技术与财务影响,并提供了...

CNC加工桥梁服务如何加速从原型到生产?
CNC加工桥梁服务如何加速从原型到生产?

对于东莞及全球各地的制造商来说,从验证过的原型到全面量产之间的差距,是产品生命周期中最关键的风险点。CNC 加工桥接服务正是通过使用量产级材料和工艺,制造 10 到 1,000 件的小批量试产,并在 5 到 15 个工作日内交付,同时保持 +/- 0.005 毫米的公差,直接应对了这一挑战。这种方法无需在设计定稿前投入...
