Shape of Weirs That Are Less Prone to Turbulence | Important Runner Design in Casting

Explaining the essential conditions for installing a weir! Introducing the cross-sectional shape of the flume (weir) and more!

The installation of weirs and riser pipes is directly linked to product quality, so careful consideration of the installation location and diameter is necessary. Additionally, we often see unnecessary riser pipes added due to concerns about casting failures. Increasing the number of riser pipes beyond what is necessary can lead to turbulence, which has a negative effect. In this column, we will explain the essential conditions for installing weirs. We encourage you to read it. 【Contents】 ■ What is a weir ■ Essential conditions for riser pipes ■ Cross-sectional shape of riser pipes (weirs) ■ Diameter of riser pipes and flow rate ■ Changes in flow rate due to differences in weir shape *For detailed content of the column, please refer to the related links.

Basics of Installing a Weir | Important Runner Design in Casting

Introducing the basics of dam installation and methods to prevent "cracks" that can occur at the junction between the dam and the product!

The definitions of the runner and the gate vary somewhat depending on methods such as sand casting, lost-wax ceramic shell method, and block molding method. The term "runner" originally refers to the path through which molten metal reaches the product part of the mold, encompassing the entire wax tree except for the pouring basin. In this column, the term "gate" specifically defines the junction between the runner and the product within the runner. We encourage you to read on. [Contents] ■ Basics of gate installation ■ Appropriate thickness of the gate ■ Methods to prevent "cracking" at the junction of the gate and product ■ Proper installation position of the gate ■ Dividing the runner into multiple parts ■ Runner sprue *For detailed content of the column, please refer to the related links.
