Aluminum profiles have many advantages and can be used to build almost all kinds of structures. However, in some cases, non-metallic materials have more advantages. This is why item developed KH profiles.
This special profile is made of a composite of thermoplastic polypropylene and wood. The wood used is PEFC certified and comes from sustainable forest management.
More than 70% of the material of the profile KH is wood fiber, so it is much lighter than the aluminum profile (1.06 kg/m) and is more ergonomic. It also has a better carbon dioxide value (carbon dioxide equivalent: 3.6 kg), as well as ideal electrical insulation and electromagnetic wave permeability.Read more
Speaking of machine tools, you might think of German machine tools and Japanese machine tools. In fact, Swiss machine tools and even the entire Swiss manufacturing industry are at a good level.
TITANS, a CNC training center in the United States, walked into the Swiss precision machining workshop and shot the video. You can feel the charm of small parts. There are more than 4,000 parts on a plate less than the size of a palm.
The Swiss have a rigorous and conscientious “craftsman spirit” and a perseverance in craftsmanship. There are many invisible champions among Swiss machine tool companies. Let’s take a look at who are these machine tool companies? (names not listed in order):Read more
Tungsten steel: tungsten steel, cemented carbide, tungsten steel manufacturers, tungsten steel tools, tungsten steel molds, tungsten steel plates, tungsten steel round bars, tungsten steel round molds, YG15, YG8, YG20, YL80, YL90
The main components of tungsten-cobalt cemented carbide are tungsten carbide (WC) and binder cobalt (Co).
The grade is composed of “YG” (the initials of the Chinese pinyin of “hard and cobalt”) and the percentage of average cobalt content.Read more
