Small offices have unique needs, and thatincludes document shredding. Designed with the smaller business inmind, the Dahle 20314 is a cross-cut shredder that offers Level 3security and brings you into compliance with federal regulations. The As we all know to live in this world we have to perform some activity by which we can earn money. There are many activities by which we can earn money and meet the standards to live in this society. And from one of them is franchise.  Franc

Automotive industry is still the largest powder metallurgy industrial development and the largest power users. On the one hand the increasing automobile production in the other hand, metal powder metallurgy parts in a single amount on the cars are not of the increase. Powder metallurgy parts per vehicle in North America the highest amount, 19.5 kg, the European average of 9 kg, an average of 8 kg in Japan. As the rapid development of Chinese auto industry has huge market potential powder metallurgy parts, powder metallurgy has become a large international business focus.Iron-based powder metallurgy parts in the car is mainly used in engines, transmission systems, ABS systems, ignition devices. Car were two major trends of development in order to reduce energy consumption and environmental protection; main technical means is the use of advanced engine systems, and lightweight. European automobile exhaust filter of porous powder metallurgy materials and provides a large market. In the current engine operating conditions, powder metal porous material than ceramic materials with better performance and cost advantage.Tool material is another important industrial powder metallurgy products, which is particularly important carbide. 3A is currently moving in the direction of the development of manufacturing, ie Agility, Adaptivity and Anticipativity. This requires the processing tool itself more sharp, better rigidity, toughness higher; processing of materials extends to co-Lu, magnesium alloys, titanium and ceramics; dimensional accuracy requirements are higher; calling for lower processing costs; to reduce environmental impact to a minimum, a greater proportion of dry machining. These new tools and materials to speed up the development of powder metallurgy. Carbide grains ( 6um); coating technology has developed rapidly, CVD, PVD, PCVD technology has improved, there are many types of coatings, from the common CVDTiCN/Al2O3 / TiN to CVD PCBN (polycrystalline cubic BN) and PVD TiAIN, Al2O3, cBN (cubic BN) and SiMAlON, etc., to meet the processing needs of occasions.Information industry for powder metallurgy industry to provide a new opportunity. Japan's electronics industry has been using the powder metallurgy products reached $ 4.3 per year, which accounted for 23% of the heat sink material, manganese powder were extremely light-emitting materials with 30%. The former includes thermal material, such as Si / SiC, Cu-Mo, Cu-W, Al-SiC, AlN and Cu / diamond and other materials; latter include tungsten, molybdenum material.Powder atomized powder has been prepared by high-performance technology. Hot gas atomization technology can extend the metal droplets in the liquid state the time, the powder can be subjected to secondary fragmentation (atomization), thus greatly improving the efficiency of atomization, the resulting powder particle size is more small. ASL's research results show that if the gas temperature to 330 . The required particle size powder prepared by the same 30% reduction in gas consumption, the economic analysis and engineering studies indicating that the technology is entirely feasible. Powder atomization in a significant improvement of technology. For example, using a new free nude gas atomization, to be more fine tool steel powder, boron powder the distribution of carbide particles is more uniform, with fewer defects. U.S. Heeg Las company advanced steelmaking technology for powder production, the integration of the arc furnace (EAF) technology, argon oxygen decarbonization technologies (ADO), high-performance spray technology and hydrogen annealing technology has greatly improved the powder quality, density and intensity of powder compacts has been improved. In the reactive powder atomization, in order to reduce the melt and crucible melting process of the reaction, the German development of the electrode induction melting gas atomization (EIGA) technology, can be prepared by high activity of titanium, zirconium and TiAl intermetallic compound powder. Study of mechanical alloying is still popular, but most of the laboratory work. It is worth mentioning that the German Zoz company developed only with their own high-energy ball milling equipment milling arc melting furnace slag, and then through the hydrometallurgical recovery of metal, this technology both to improve the environment, open up a huge market.
