  Learn More Ab out LEDs 1. What is an LED? A light emitting diode (LED) is a tiny, electronic semiconductor that converts electric energy into visible light. The chemical compound used within an LED determines its color, brightness and power efficiency. Unlike incandescent lamps, LEDs have no filaments that can burn out or fail. Surface Mount LEDs Surface Mount Devices, or SMD for short, refers to the LED lead frame mounting method. LEDs are mounted to the surface of the circuit board. The SMD contains red, green and blue die. Through-Hole LEDs Through-hole LEDs are mounted with leads protruding through the circuit board and appear to stand taller. Each LED is a single-color die of either red, green or blue. LEDs come in two different forms. Manufacturers use several types of LEDs to construct digital displays. The two most common are Through-Hole LEDs and Surface Mount Device (SMD) LEDs, also known as Surface Mount Technology (SMT). Each type has its respec

BRIEF INTRODUCTION OF CASTING | Ngdxtech.com

  Casting is the process of melting the metal into a required liquid and pouring it into the mold. After cooling, solidifying and cleaning, a casting (part or blank) with a predetermined shape, size and properties can be obtained It is the basic technology of modern machinery manufacturing industry. The cost of casting blank is low, especially for the parts with complex shape, especially with a complex cavity, it can show its economy, at the same time, its adaptability is wide, and has better comprehensive mechanical properties. However, there are more materials (such as metal, wood, fuel, molding materials) and equipment (such as metallurgical furnace, sand mixer,   grinding ball molding machine , core making machine, sand falling machine, shot blasting machine, etc.) needed for casting production And will produce dust, harmful gases and noise and pollution of the environment. Casting is the process of melting the metal into a required liquid and pouring it into the mold. After coolin

UNDERSTAND NORMALIZING, ANNEALING, QUENCHING AND TEMPERING (1)

  1. Tempering for grinding casting ball : The microstructure obtained by high-temperature tempering is tempered sorbite. The main purpose of tempering is to eliminate quenching stress and get the required structure. According to the different tempering temperature, tempering can be divided into a low temperature, medium temperature, and high temperature. Tempered Martensite, troostite, and sorbite were obtained. The quenching and tempering heat treatment is called quenching and tempering heat treatment, which aims to obtain the strength, hardness, and plasticity, toughness is better comprehensive mechanical properties. Therefore, widely used in automobiles, tractors, machine tools and other important structural parts, such as connecting rods, bolts, gears and shafts. Hardness after tempering is generally HB200-330. 2. Annealing The main aim of annealing is to make the internal structure of the metal reach or close to the equilibrium state and to prepare for the subsequent processing a

IMPLANT DRILL USAGE | Xmystool.com

  Your pilot drill and osteotomy formers are not meant to last forever. When they are sharp, these instruments will cut efficiently and accurately. These burs, especially the pilot, take a lot of abuse as they go through cortical bone. On top of that, every time they are heat sterilized, there is degradation of the cutting edge. All this results in a less than ideal cutting instrument. If you are using dull pilot drills, you will find that you need to use more pressure to drive the bur through bone. Your osteotomy formers will also not cut smoothly and effortlessly through bone. This inefficiency can result in heating of the bone and possibly a larger osteotomy than recommended. Both of these can result in lack of primary stability and possibly failure of your implants due to bone necrosis. Yushang  recommends that your pilot be changed out every 15th osteotomy and your osteotomy formers should be replaced every 20th implant (depending on bone density) in order to keep them efficiently

  Table lamps   are one of the most widely used lighting options because they can be used in just about every room. The top three spots for a table lamp are: 1. On a console table A console table is a hallway staple and a luxury table lamp makes the perfect partner. Not only do they provide light for those moments when you really need them, but also they add interest to an often unsung space. 2. On a side table Lighting schemes are often rounded off by a layer of lighting around eye level, so a table lamp on a side table is a great option particularly in a living room or sitting area. They offer a flattering pool of light which counteracts unflattering shadows from general lighting and often act as the invisible boundaries of an intimate seating area. 3. On a bedside table When is subtle lighting more needed than at bedtime? A carefully chosen bedside table lamp will create a calming, romantic mood. Bedside table lamps shouldn't feel overwhelming though so, unless your furniture is
