Established in 1990, Fadong Power Co., Ltd. is a professional China engine block manufacturer and supplier of in the emergency power supply industry. We not only specialize in manufacturing different kinds of generators, but also in motors, engines, diesels, gearmotors and other power supply products. We also have more than 100 series of equipment to support and check our products, such as VPI equipment, auto painting lines, auto testing systems and CAD systems. We warmly welcome every customer to cooperate with us on the basis of mutual benefit, and hope to be your faithful friend and best partner. Our custom engine blocks has obtained the certifications of ISO9001-2000, GS/TUV, CE, VL, EPA, QHS, SON, CAP and SRS.

Aluminium foundry alloys used in the production of such complex cast parts as engine blocks and cylinder heads must meet a combination of requirements which include low cost, castability, machinability, and moderate strength at elevated temperatures. Alloys commonly used in these applications include AA 319, AA 320, AlSi5Cu3, and AlSi6Cu4 (A23). These are all secondary hypoeutectic Al-Si alloys whose relatively high Cu content enables them to retain their strength at elevated temperatures as well as making them easily machinable. The parts may be T6 tempered but for many designs a T5 stabilizing temper is frequently sufficient. Some heads have even been put into service in the F-temper. These alloys have proven themselves over time to be the best engineering compromise for gasoline engines. Diesel engine cylinder heads may be cast out of AA 356, AA 357, AA 359, AlSi7Mg or AlSi9Mg. The higher resistance to cracking in the plastic regime that these alloys display enables them to survive the much harsher thermal fatigue loading conditions encountered in this application. There is some sacrifice in machinability (mainly burring) and added cost in heat treatment since a T6 or T7 temper is usually required. Cast aluminium cylinder heads and engine blocks generally weigh only half as much as ferrous castings.

Our shot-blasting machine employs a cleaning method using stainless steel shot. This finishing process is used by Promar to remove surface contamination such as rust and irregularities from engine blocks during remanufacturing. The result of this method is a cleaner smoother surface finish to make easy the detection of surface and subsurface casting defects during quality inspection.
To insure stress free casting, the peening process is used to impart compression strength to metal parts. This is accomplished by metal shot pellets acting like miniature ball peen hammers as they strike the entire surface of the block. All iron castings are put through this process before a preliminary inspection for defects is done. This process using the AR HB41 is employed for cast iron blocks only and facilitates a more accurate magnetic particle inspection.
