Die Casting
- 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

- How to Solve Mechanical Scratches of Die Casting?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 mDie Casting August 03, 2020
- Basic Requirements for Alloy Die CastingThe low melting point temperature of the Alloy die casting is beneficial to prolong the service life of die casting mold.Die Casting August 05, 2020
- Causes and Solutions for the Air Holes in Aluminum Alloy Die CastingAluminum alloy die casting has some advantages that other castings can not compare, such as good looks, light weight, corrosion resistance, so that it is widely favored by users. But aluminum alloy die casting is prone to porosity and impurities, so how to solve this problem? Firstly let’s see how dDie Casting November 05, 2019
- It’s important to choose a suitable die casting machineMany customers think it is more cost-efficient, faster and more efficient to use a large-tonnage die-casting machine to die-cast small zinc alloy parts. In fact, this view is wrong!Choose a right die-casting machine with suitable tonnage for a set of zinc alloy die casting parts is extremely necessaDie Casting October 28, 2019
