How to improve the way of magnesium alloy die casting
Copy from:    Author:kenostian    Time:2016-03-09 16:51:23    Popularity:410

   The way of magnesium alloy die casting using cold chamber die casting machine or hot chamber die casting machine. At present the improvement of hot chamber die casting machine mainly includes: using energy storage booster, the injection speed of the injection ram can reach 6m/s; induction heating gooseneck pipe and a nozzle to keep the optimum temperature; double furnace melting heat preservation, and the use of heat insulation equipment and recycling pipeline, accurately maintain the molten pool temperature. When the die casting magnesium alloy is used in the common cold chamber die casting machine, must carry on the necessary transformation to the die casting machine of the injection system and the automatic feeding system, so that it is suitable for magnesium alloy die casting.
   Need to transform the contents include:
(1) The fast injection speed of the injection system is increased from 4 ~ 5m/s to 6 ~ 10m/s;
(2) Shorten the time to build up the pressurization process;
(3) Increase the compression force;
(4) The use of electromagnetic automatic dosing device to prevent the oxidation of magnesium alloy in the pouring process;
(5) If special die casting process is adopted, the necessary equipment is equipped, such as vacuum die casting, etc..
