The gate position refers to the entrance of metal liquid into the casting cavity, commonly known as the feeding position or the inlet position.As far as possible, the spout position makes the flow of metal liquid short, low resistance, small pressure loss, filling time moderate, so as to ensure the Read More »

Mold retention time: the time from the end of the hold-down stage to the release of the die casting. The purpose of this time is to ensure that the casting is fully solidified, cooled and has a certain strength in the die, so that the die casting will not be deformed or cracked during the release an Read More »

The low melting point temperature of the Alloy die casting is beneficial to prolong the service life of die casting mold. Read More »

Mechanical scratches is a linear scratch on the surface of the die casting during core-pulling and push-out.Causes of mechanical scratches mainly include the following aspects:Demoulding agent lubricity is not good, the mold temperature exceeds the adhesion temperature of demoulding agent, coating m Read More »

Shrinkage rate of die casting refers to the relative change rate of die forming size and actual size of die casting at room temperatureThe shrinkage rate of die casting includes liquid volume shrinkage of metal liquid, solidification phase transformation shrinkage and solid volume shrinkageThe more Read More »

After the metal liquid fills the cavity, the time required under the action of pressurization and specific pressure until the internal gate is completely set is called holding time.The effect of holding time is to crystallize the solidifying liquid metal under pressure, thus obtaining a die casting Read More »

There are four flow modes when the metal liquid fills the mold cavity: jet flow, pressure flow, re-jet flow, and supplementary metal flow.Injection flow: In the initial stage of die casting, the molten metal passes through the inner sprue at a high speed, driven by the injection punch, and is shot s Read More »
