In the realm of mechanical engineering, various standards govern threads, and it’s time to organize and summarize them. Threads, whether metric or imperial, straight or tapered, sealed or unsealed, internal or external, with angles of 55 or 60 degrees, often…
The earliest firearm: “铳” Firearms have a long history, starting in 10th-century China. People then created early versions by putting bamboo tubes with gunpowder and pellets on spears. These portable “fire lances” could be operated by just one person. They…
As an integral part of injection molds, the water channel is located within the mold to guide the flow of cooling water, controlling temperatures, and expediting the cooling process. The mold cooling system is a crucial factor influencing the quality…
What are the axes of a CNC machine? When we refer to the axes of a CNC machine, we’re essentially delving into the spatial dimensions along which the machine can move and operate. Each axis represents a specific direction, and…
I. What is Turn-Milling CNC Machining? CNC machining, short for Computer Numerical Control machining, is a manufacturing process that utilizes computerized controls to manipulate cutting tools and equipment for precision machining. Within the realm of CNC machining, there exists a…
Introduction Passivation is a commonly used method for treating metal surfaces. Like many other surface treatment processes, its primary purpose is to protect metal surfaces from rust and corrosion. What sets the passivation process apart from many other surface treatment…
Sheet metal fabrication is the art of transforming raw metal sheets into various components and structures, serving a multitude of industries. While you may already be well-acquainted with the basics, we will delve deeper into the nuances that impact the…
MIG and TIG welding are two popular welding methods that share similarities, such as utilizing an electric arc and a shielding gas. However, there are distinct differences, particularly in the type of welding electrodes employed to establish the arc. MIG…
Ribs in injection-molded parts add strength and stiffness, making the part more rigid. Without ribs, we’d need a thicker, heavier part to achieve the same stiffness. To avoid excessive sinking and weight, the ribs’ thickness should be about 50% of…
Some undercut features are inevitable In the injection molding process, it’s important to avoid designs that have undercut features, as they can cause problems when removing the product from the mold. But sometimes, these undercuts are necessary for the product…
