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 »

The essence of CAE simulation is the physical model formed after highly approximating the actual production process, and the process of solving and displaying the key physical field variables with numerical methodsThe complete CAE simulation process includes: pre-processing, calculation and solution 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 »

The casting hot spot refers to the isolated area where the metal liquid cools and solidifies at some local locations during solidification in the mold cavity.The formation of hot spots usually depends mainly on the casting structure and wall thickness distribution (internal causes), and the local he 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 »

Mold cooling methods are mainly air cooling and water cooling two kinds.Air cooling characteristics: The air cooling mainly comes from compressed air;There is no need to set the cooling device in the mold, and the structure is simple;It can evenly blow the paint inside the mold cavity, accelerate an Read More »
