- 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
- The Role of Heating and Cooling SystemsBefore the die casting production, the mold should be fully preheated and kept within a certain temperature range during the die casting process. Its main functions are as follows:The die can achieve better heat balance and improve the solidification condition of casting sequence so that the solidif
- Customer Case of Investment CastingThe commonly used stainless steel material in Sieg-Huao includes 304, 316,316L and 17-4PH among which 17-4PH is much special. 17-4 PH is a martensitic, chromium-nickel-copper precipitation-hardening stainless steel. 17-4 PH stainless steel is capable of attaining a wide range of strength and toughneInvestment Casting March 25, 2019
- Universal Law of Shrinkage of Die CastingThe casting structure is complex, Core more, The shrinkage rate is small when the shrinkage of obstruction is larger，On the contrary, the shrinkage rate is largerThe radial dimension of the casting core is in the direction of obstruction and the shrinkage rate is small, while the dimension parallel
- 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
