In recent years, the consumer electronics market has developed rapidly, and the renewal cycle of many consumer electronics products is getting shorter and shorter. In addition to product technology innovation, various packaging materials have gradually changed from plastics to metal materials. This is because the metal cost is getting lower and lower, the products are getting lighter and lighter, more environmentally friendly, more practical and more beautiful, and more and more electronic manufacturers are starting to “replace the case”. Although some electronic products us......

Many producers are expected to discover that die-casting aluminum is not suited for anodizing treatment while performing surface treatment on various aluminum materials. All of this is governed by the composition of die-casting aluminum and the anodizing characteristics, so why is die-casting aluminum not suited for anodizing? To begin with, anodizing requires no imperfections on the aluminum’s surface, and the aluminum must be relatively pure because the anodized layer must be uniform and flat. Excessive impurities and other components will inevitably affect the thickness ......

In the normal production process of oxidation electrolytic polishing, the composition of the electrolyte is relatively constant, while the operating conditions are variable. For different materials and surface effect requirements, the required polishing is often obtained by changing the operating conditions. The influence of surface effect and operating conditions on polishing quality mainly includes the following aspects. 1. Temperature The temperature determines the viscosity and volume resistance of the electrolyte. For aluminum electropolishing, only when the solution ha......

Mechanical keyboard, so many axes, which one should you choose? On mechanicalkeyboards.com (mechanical keyboard. com) in the United States, the ratings of mechanical keyboard users on each axle body are counted. The user will rate the used shaft body from the three perspectives of “game”, “typing” and “comprehensive”.   Today we will focus on Cherry’s seven axes (the gray axis is not in the statistics). Before comparing the values, let’s see how many people have scored. This grou......

For the current office work, especially the work requiring codewords for a long time, what keyboard is suitable for the office? Before we talk about what keyboard is suitable for use, let’s first analyze the requirements for a suitable keyboard in the office. One is that the sound will not be too loud, the other is that the keys will not have too much damping as far as possible, and the third is that the service life will be longer.   The main difference that affects these three points lies in the keyboard bearings. Ther......

For computer enthusiasts, the metal texture of the mechanical keyboard and the sound of the mechanical equipment are a kind of enjoyment for keyboard users. The modeling design of the mechanical keyboard frame is one of my favorite hardware configurations, especially the glaze color, which is very intoxicated when the computer is typing. Nowadays, DIY keyboard has become a great pleasure for computer enthusiasts, and preference for design schemes is becoming more and more important. Sometimes, it is a headache to choose a suitable keyboard frame. In the next time, CNCJY will show you ho......

During anodizing, pitting is one of the more common faults in electrolytic polishing. The content of chromic acid in the electrolyte is too high, the temperature is too high, the current density is too high, the content of sulfuric acid is too low, the viscosity is too high or too low, chlorine Excessive ion content, excessive trivalent chromium content, unreasonable stirring and poor pretreatment before electrolytic polishing will all lead to pitting during anodic oxidation. If pitting occurs during anodizing, what should we do? If pitting occurs on the surface of the workpie......

As the name suggests, the mixed-axis mechanical keyboard is to use a variety of axes on a mechanical keyboard, which not only satisfies the curiosity of users, but after all, the price of a mechanical keyboard is relatively expensive. Users bought a mechanical keyboard with a certain axis. The mixed-axis mechanical keyboard actually appeared very early. As early as 2010, Erik and Duck launched the mixed-axis mechanical keyboard, but due to the small number of products and the small influence, they stopped. The theory of the mixed-axis mechanical keyboard is actually derived from......
