Die-casting wall thickness and the filling time close relationship with the thinner walls, filling the shorter the time. Can provide a stable firing rate of fast-pressure die-casting machines and high-performance high-speed filling does not occur under the conditions of flying edge high-precision, high rigidity aluminum alloy die-casting mold is a necessary condition for thin-walled. Summarizes the different thickness aluminum die-casting under the flow of the length of the wall thickness of 1.0mm following definition for ultra-thin wall. Super-book-wall die-casting process elements: a release agent. The use of high-temperature adhesion and good oil and water release agent, spraying time should be brief, and the release agent at high concentrations. 2 Injection casting room. Should be prevented from Injection to reduce the indoor temperature of molten aluminum and filling rate is low,
    Should adopt the ceramic cavity of the pressure chamber or shot Injection directly heated room, and the use of powder lubricants and insulating effect of a good hot fire chamber is also good results. 3 Injection filling. Must have a very high rate of injection. More general use ultra-thin die-casting machines and die-casting machine with the P-Q2 map, ultra-thin pressure die-casting must have a great shot pressure. In order to ensure stable high-speed injection, injection rooms shall have sufficient lubrication, it is recommended to use oil-based lubricants. Cavity of the back pressure will hinder high-speed injection, should give full consideration to the exhaust cavity, can be used a vacuum die-casting. If the exhaust pressure to consider the indoor shot is better; four coagulation. Thin  Wall die-casting during solidification and shrinkage of the process is easy to produce shrinkage and cracking, so casting the structure should be possible to make uniform wall thickness, and to prevent cracking of the response is to be located at the corner fillet. 5 mold pickup. Mold as soon as possible after the top of a casting, still hot when you pick a smaller shrinkage stress is best. Ultra-thin-wall casting molds points: a casting shape. Wall thickness should be uniform, to set rounded corners and strengthen the tendons and a large pull-mode gradient. After the cavity surface can be properly polished bright sand in order to improve liquidity and to prevent mold cracking; 2 gating system. First Injection chamber diameter and position within the runner, injection rooms with diameters ranging from mold filling time and filling rate decision;
Inside runner with wide, and can shorten the distance and the smooth filling of the main points. Runner as far as possible the structure of thin and small form in order to eliminate gas volumes; overflow tank can not be too large, otherwise the boost could easily cause a slow shrinkage and cracks; 3 die temperature. To maintain a high mold temperature, can use oil heating and electric heating, electric heating is recommended. To ensure that the insulation effect, you can set the inserts on the back of insulation materials; 4 out. Ultra-thin-wall die-casting as much as possible the use of coarse mandrel, mandril variable cross-section may also be used to prevent the mandrel bending deformation.
