Hello everyone, this is Tomon. As an R&D engineer engaged in copper processing technology research for many years, I have focused on solving the pain points of stain contamination and oxidation of exposed copper surfaces after wire drawing. Through long-term experiments and on-site verification, I have summarized a set of practical technical solutions, which I […]

内容 [tomoon Technology Popularization | Anti-Corrosion Guide for Stainless Steel After Heat Treatment, Protecting Long-Term Durability of Materials ✨] Although heat treatment can optimize the mechanical properties of stainless steel, it is prone to forming oxide scale and residual stress on the surface. If anti-corrosion treatment is not properly done, problems such as pitting corrosion

3D printing, also known as additive manufacturing (AM), has revolutionized industrial production, prototyping, and customization across aerospace, medical, automotive, and consumer electronics sectors. As a critical technology for modern engineers, understanding the core 3D printing processes is essential for selecting the right solution for specific project requirements. This article provides a concise overview of mainstream

The reliability of the metro platform door lock emergency manual release mechanism depends not only on its design but also on proper installation. Incorrect alignment, poor calibration, or improper mounting can lead to system failures during emergencies. Therefore, installation is a critical stage for ensuring future safety performance. 1. Pre-Installation Requirements Before installing the mechanism, technicians must

Electrical failures can happen in any metro system due to equipment malfunctions, short circuits, environmental factors, or external power grid issues. When the power cuts off, the automatic control system for platform screen doors (PSDs) becomes temporarily inactive. In such cases, the metro platform door lock emergency manual release mechanism becomes the only reliable method for unlocking

Metro platforms are dynamic environments. Passing trains generate high-frequency vibrations, structural tremors, and repetitive mechanical shocks. Over time, these conditions can cause metal fatigue, loosening of screws, or misalignment of precision parts. To ensure reliable performance, the metro platform door lock emergency manual release mechanism must be designed with advanced vibration-resistant engineering. 1. Vibration Challenges in Metro

The metro platform door lock safety interlock mechanism is the foundation of passenger safety in modern subway systems. In high-traffic urban stations, PSD (Platform Screen Door) systems often operate thousands of cycles every day. This intense usage requires a locking mechanism that not only prevents accidental opening but also maintains structural stability under repeated stress. 1: High-Traffic

A modern PSD system relies heavily on the metro platform door lock safety interlock mechanism to maintain predictable and safe door movements. In rail transit environments, unpredictable faults can cause elevated risk if the locking system lacks fail-safe protection. 1: What “Fail-Safe” Means for Metro DoorsFail-safe engineering ensures that in any unexpected situation—power loss, sensor deviation, or

By ToMoon Engineering Team Stainless steel is indispensable in aerospace, marine, and industrial equipment due to its superior corrosion resistance and mechanical strength. However, welding disrupts its passive chromium oxide (Cr₂O₃) film, triggering issues like intergranular corrosion and pitting—threats to structural reliability. Drawing on ToMoon’s field experience across aerospace, marine, and industrial projects, this article
