As the core acoustic component of mobile devices, smartphone speakers rely on precision micro-welding and assembly to deliver Hi-Fi sound in ultra-slim designs. Their performance & lifespan depend entirely on coil weld quality, magnetic coating uniformity, and component fit accuracy. Check out our metallographic sample prep workflow for crystal-clear micrographs: 1️⃣ P180 SiC disc → […]
In the industrial kingdom woven by steel and iron, welds never seek the spotlight, yet they hold the core power to prop up countless pieces of equipment and projects, truly deserving the name of invisible “life veins”. From the steel structures of bridges spanning rivers, to the aero-engines soaring through the sky; from the shells […]
As high-performance heat transfer components, finned tubes boost heat exchange area dramatically by adding fins to the base tube surface. This enables more compact, efficient heat transfer—making them indispensable across key industrial sectors. The welding quality between fins and base tube is non-negotiable for equipment safety & lifespan. Secure metallurgical bonding is a must to […]
In the manufacturing of drill bits and cutting tools, metallographic inspection of metal powders prior to sintering serves as the fundamental guarantee for quality control. By preparing and observing raw powder samples, the internal microstructure can be directly evaluated—including the degree of pre-alloying, morphology of primary carbides, and purity—thus predicting the uniformity of the sintered […]
When it comes to gypsum rock, don’t just think of construction gypsum boards! This sedimentary rock formed from calcium sulfate minerals has plenty of hidden talents. Its formation dates back to ancient oceans or lakes. As water evaporated, calcium sulfate crystals gradually precipitated and compacted, eventually forming the gypsum rock we see today. It is […]
Thermal spray coating is known as the “protective armor” for industrial components, widely used in machinery, aerospace, energy and other fields. It not only provides wear-resistant protection for easily worn shafts and blades, but also builds a corrosion-resistant barrier for pipelines and containers in corrosive environments. Additionally, it can realize functions such as heat insulation […]
