【Casting Pits】 Turbulence of Molten Metal and Countermeasures | Important Runner Design in Casting
Explaining how to prevent "turbulence in molten metal" with illustrations! Introducing turbulence generated by center sprues and more.
When installing the pouring system, it is very important to consider the flow of molten metal. By fully understanding the flow of molten metal during casting, the solidification time of the metal, and the characteristics such as viscosity and surface tension of the molten metal, and by taking appropriate measures, we can reduce casting defects. In this column, we will explain how to prevent "turbulence of molten metal," which is one of the causes of entrapped air defects, using diagrams. We encourage you to read it. [Contents] ■ Turbulence of molten metal ■ Turbulence generated by center sprue ■ Turbulence caused by L-shaped geometry ■ Turbulence caused by T-shaped geometry ■ Turbulence caused by U-shaped geometry *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."
