When we are used to the rapid changes in the market, smart locks come in a dazzling array, and we are dazzled by all kinds of smart locks. No matter how intelligent the product is, the smart lock can’t break away from the function of anti-theft. No matter how smart the product is, no matter how smart it is, no matter how smart it is, it must have a high-precision composite structure anti-theft lock cylinder. What conditions should a good anti-theft lock cylinder have? Today we will teach you how to identify the material of a good lock cylinder & how to choose a good lock cylin......

Guitar string tuning pegs have many aliases: string axis, rotary tuning pegs, string alignment, head tuning pegs, etc., which refer to the parts on the head of the guitar used to fix the strings and tune. In the early days, the selection range of guitar string tuning pegs was very small. Few companies produced metal string tuning pegs. Most of them were wooden string tuning pegs like violin or pipa. However, it was inconvenient to use them on folk guitar with metal wire. The turnbuckles of violins are mostly made of hardwood John Frederick Hintz was one of the earliest k......

If you’re in the market for a new keyboard, you’ve probably come across the terms “mechanical keyboard” and “ordinary keyboard.” But what is the difference between them? Check this guide and we make a comparison for mechanical keyboards vs ordinary keyboards Mechanical Keyboard Vs Ordinary Keyboard At present, most of the mechanical keyboards on the market are connected by soldering, which is commonly known as “soldering keyboards”. Its shaft body is welded on the PCB board, which has the advantage of stable connection. If you ha......

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......
