  • Effect of Raw Material Quality on Forgings
    Posted: 07/03/2015 14:04:38  Hits: 157
    Good quality of raw materials is the necessary prerequisite to ensuring production of quality forgings. Defects of raw materials will influence forming process and final quality of forgings.   If chemical element content of raw materials exceeds specified range or content of impurity elemen...
  • Quenching Process by Remaining Heat from Forging
    Posted: 06/16/2015 16:47:10  Hits: 162
    Conventional heat treatment of forgings is mostly such heat treatment of cooling forgings to room temperature and reheating them based on technological procedure. However, quenching process by remaining heat from forging is such heat treatment of using remaining heat from forging for direct quench...
  • Characteristics of Magnesium Alloy Die Castings
    Posted: 05/27/2015 14:33:14  Hits: 198
    Magnesium is the lightest among commonly used metals. It is one of the most abundant elements in earth crust, accounting for 25% of earth crust. Its melting point, namely 650°C, is nearly the same as melting point of aluminum. But it is lighter than aluminum and its density is equal to one thi...
  • Forging Methods, Advantages and Applications
    Posted: 05/11/2015 16:22:00  Hits: 185
    Forging is a manufacturing process of flattening, hammering or extruding metals with great pressure to form high-strength metal parts. In general, except in special cases, metals before forging should be preheated to reach anticipated temperature. It is noted that forging and casting are different...
  • Features of Magnesium Alloy Castings
    Posted: 04/29/2015 08:39:58  Hits: 365
    Magnesium alloy castings are characterized by light weight, good rigidity, corrosion resistance, dimensional stability, shock resistance, abrasion resistance, good attenuation property and easy recycling. In addition, they also have excellent thermal conductivity and electrical conductivity, no ma...
  • Cooling Process after Forging of Stainless Steels
    Posted: 04/08/2015 22:53:46  Hits: 337
    Martensitic stainless steels are sensitive to cooling rate, even air cooling. During cooling process, cracks are prone to occur due to relatively great cooling stress caused by martensitic transformation. As a result of non-concurrent martensitic transformation of forging surfaces and internal for...
