Powder forging process and its application Business Articles | April 12 Wholesale NFL Jerseys Free Shipping , 2012
Powder forging process successful developed at the end of last century is an advanced metal plastic forming high-tech. It has the advantages of high-quality, high-precision, high efficiency, low consumption and low cost.

It can meet the production requirements of low-carbon, energy saving and environmental protection in the 21st century. At the same time, it creates the need for rapid development of modern cars.

The end of the last century Wholesale NFL Jerseys From China , foreign-developed a new type of metal plastic forming process of powder forging, has tempered the automobile differential planetary gear and connecting rod forgings and built the world''s first powder forging production line. It is the organic combination of the conventional manganese powder metallurgy process, and precision-forged and developed a considerable market competitive without cutting metal processing methods. Metal powder as raw material, after pre-shaping to suppress heating sintering in a protective atmosphere and as rough forging, and then forging and flash precision die forging press time, the same density and ordinary forging complex shape precision forgings.

It has not only the advantages of powder metallurgy Wholesale NFL Jerseys China , but also plays forging deformation characteristics to effectively change the organization of metal materials and performance. It achieves a new breakthrough in production of powder metallurgy forging process is the edge of professional disciplines. It is especially suitable for mass production of high strength, complex structural parts and promotion in various industrial fields.

Powder forging process is the appropriate formula and mixed powder used in the manufacture of ordinary sintering in the same way to shape, made of low-density pre-formed parts, and as a rough forging, hot state after sintering forging. Should be increased before the sintering preshaped form containing lubricant, lubricant removal process. After sintering Wholesale NFL Jerseys , cooling, re-heating before forging. Before the heat treatment after forging, often require some degree of machining nickel powder. In addition to the short period of time forging all heating throughout the process in the oxidation of the protective atmosphere.

There are two ways for sintered body forging process: First, the use of waste heat insulation to the forging temperature of the sintered immediately forged in order to save energy. Second, the sintered body cooled to room temperature after re-heating, and then forging the relative increase of the energy consumption of this law. Sintered by the densification of closed die forging Wholesale Sports Jerseys , 80% theoretical density of sintered forged up nearly 100% theoretical density. It must be noted that in the forging deformation, the shape of the preform design should be reasonable, in order to reduce the lateral flow of metal and to alleviate the wear and tear of forging die.

As the powder particles smaller, poured into the mold cavity as fluid around the filling cavity, forming a very high-performance of a variety of complex shape forgings smoothly. The rough parts of the material utilization reached 100% that does not leave any metal allowance and dressing. Forging the heating temperature is low, and because in the oxidation protection of atmosphere Wholesale Jerseys Cheap , there is no oxide scale. It can obtain high dimensional accuracy and low surface roughness of the forging boron powder. The workpiece surface by the mold cavity at a high temperature smooth the surface of the ironing and gloss.

Compared with the ordinary forging processing methods, firstly, it has high machining accuracy. Thus it can greatly save machining, improve material utilization, save time and reduce costs. Because raw material powder possesses a higher proportion in the cost, the production proves that the applications of powder forging in machine parts which can save the impress are more favorable. At present Wholesale Jerseys Free Shipping , the powder forging process has become matured as a streamline processes. It will reduce pollution and conserving natural resources. It is a cross-century advanced high-tech in line with the requirements of the times.Source:http:www.mhcmp

As a tool for transport, the ebike has benefited from the talented designers and the high-developing tech that is bringing pleasure and good experiences to our daily life. But for our amateur, we have no clear cognition of every core component in the bike as well as theirs application. Knowing the details could get ready for your cycling and help you acknowledge the professional knowledge.

Colorful display (wristband):
Freway screen is the electronic products that can calculate the dump energy and operate the assistant system. There are also information about temperature. The Freway 2th generation will launch the smaller and smarter wristband Wholesale Jerseys From China , it replaces the display screen and was designed for the Freway APP, it shows the speed, calories. pedal frequency. While the wheels moving, the inductor traces the information from the induced magnet and deliver to the wristband, usually, the data we see is the result after processing.

Derailleur
Bicycle derailleur works like this: it does the cooperation between chain and gear plate to change the bike speed. The size of the two plates decides how much strength you will cost. The smaller for before plate and the bigger for later plate Wholesale Jerseys China , the less strength you will spend. Freway provide three-level assistant. people can adjust the working condition of the gear plate to change the cycling speed, with the need of different road condition.
