When choosing system doors and windows or aluminium alloy doors and windows, many people tend to look first at the profile thickness, glazing specifications, thermal breaks and the price of the entire window, yet they often overlook a key element that truly affects the long-term user experience: door and window fittings. Door and window fittings are not merely a few simple components.

Manufacturing is the foundation of national strength, please pay attention to “metal processing” (mw1950pub).

Following decades of development, prototype manufacturing has evolved into three core process systems centred on CNC precision machining, 3D printing rapid prototyping and vacuum casting. This article will examine these systems from four key perspectives: process principles, strengths and weaknesses, material suitability, and application scenarios.

01 Machining Error Analysis Errors in machining have a profound impact on the overall process performance. In order to improve the productivity and quality of mechanical products, we must break through the limitations of machining technology to effectively reduce and control these errors. However

Industrial photogrammetry is one of the more popular non-contact, wide-area scene measurement techniques today, with relatively mature technology development and a wide range of applications.

As industrial development accelerates, machine tool processing is becoming increasingly important in industrial production. Machine tools, as essential instruments in this process, have gradually evolved into common types such as lathes, milling machines, planers, boring machines, drilling machines and grinding machines. When it comes to the machining processes involved in various techniques,

We generally classify manufacturing processes into two types: material removal and material addition. Most of the processes we use involve material removal, although material addition is also practised; this is generally referred to as forming. For example, injection moulding is a form of material addition; however, our focus here is on material removal.

I. The Transformation of Welding Technology in the Industry 4.0 Era As the cornerstone of smart manufacturing, Industry 4.0 is propelling the manufacturing sector into a new era of digitalisation and intelligentisation through the Internet of Things (IoT), artificial intelligence (AI), big data analytics and robotics.
