Aluminum alloy die casting
Aluminum alloy die casting products are mainly used for electronic、A car、The motor、Some home appliances and communications industry, etc,Some high-performance、High precision、High toughness of high quality aluminum alloy products is also used in large aircraft、Shipping requirements such as high in the industry。The LordcTo use or on some equipment parts。
Metal casting
Metal mold cooling fast,Casting organization is relatively dense,Heat treatment can be improved,Mechanical properties is higher than sand mold casting15%The left and right sides。   The metal mold casting,Casting quality is stable,The surface roughness is better than that of sand mold casting,The rejection rate is low。   Good working conditions,Productivity is high,Workers are easy to master。
The invalidation forms and mould design key points of die casting mould
1、Die casting mould thermal fatigue crack failure during die casting production,Die casting die again and again by chilling the role of heat shock,Molding surface and its internal deformation,With each other and appear repeatedly cycle thermal stress,Lead to organizational structure damage and loss of resilience,The emergence of micro cracks,And continue to expand,Once the crack expansion,Fluid diapir and molten metal,Repeated mechanical stress are combined to make acceleration of crack extension。To do this,On the one hand, die casting mould must be fully preheat starting。In addition,In the process of die casting production die casting mould must be kept in a certain operating temperature range,In order to avoid in early crack failure。At the same time,Be sure to die casting
What do excellent mold design?
1、View width excellent mold designers not only technical excellence,There will be enough vision broadband,Of the latest developments in mould industry。Study of new product design layout,Mold design experience,Can say,Excellent mold designers are good at learning。2、Trade-offs measure mold development for so many years,Actually have a rapid growth of various options,But each mold lasts only a plan,So how to choose the most appropriate solution is need to test the strength。3、Track the mold process must not feel finished mould design is ok,In fact,Whether in the process of open mould,Or try mould and mass production,All
