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.

Company information
Our company, established in 1960, was the first in Japan to develop and sell domestically produced casting machines for jewelry, making us the longest-established casting machine manufacturer in the country. Currently, we manufacture and sell both analog and digital devices for melting and casting various metals and alloys, not only for the jewelry industry but also for companies in all sectors. We do not just sell products; we provide technology. We propose the most suitable casting machines while listening to what our customers want to create, and we also offer customization based on their requests and suggestions for consumable materials that match their products. After purchase, we support our customers to ensure they can create products that align with their vision under our technical guidance. Additionally, we are focusing on proposals for casting production using 3D printers and low-cost prototyping technologies, contributing to the future of "Japanese manufacturing."
