- How to Choose the Gate Location?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 theDie Casting October 10, 2020
- What is Die Retention Time And What Effects Does It Have?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 anDie Casting October 09, 2020
- What Is The Shrinkage Rate Of Die CastingShrinkage 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 moreDie Casting July 20, 2020
- What Is Holding Time?What Are The Main Factors That Affect It?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 castingDie Casting June 29, 2020
- There Are Four States of Liquid Metal FlowThere 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 sDie Casting May 25, 2020
- What Is Die Retention Time And What Effects Does It Have?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 anDie Casting April 20, 2020
- What is The Slow Injection Rate?The slow injection velocity collects the first stage injection velocity in the three-stage injection system. After the metal liquid is poured into the pressure chamber, the filling degree of the metal liquid in the chamber is generally controlled at 50%-80%, and the rest space is filled with air. Th
- Another Important System for Mold Quality Control!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
- An Important Factor Affecting Die Casting Defects, ——How does Hot Spot Occur?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
- How to Understand Simulation? Do You Have the Right Idea?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
