Ductile Iron Investment Casting Parts
Product Details

Brief Introduction

Ductile iron, also known as ductile cast iron, is a type of graphite-rich cast iron alloy for iron castings. Ductile Iron contains spheroidal (nodular) shaped graphite, is higher strength than Gray Iron, and weighs about 10% less than steel for the same section size.


  • Excellent strength to weight ratio

  • Low cost

  • More impact and fatigue resistance

Specific operation

The alloy block is placed on the bottom of the bag and covered with iron filings (also available in thin steel plates). When the molten iron is full, stir the molten iron with a stir (accelerate the reaction) and add straw ash (reduce heat radiation and oxidation) to the iron water immediately. When the spheroidization reaction is over, take out a small amount of molten iron with a sampling spoon, pour the test piece into a shape, solidify and then water-cool, cut off, and check the section to judge the degree of spheroidization. After the requirements are met, the molten iron is poured into the ladle and cast. A process in which a metal is smelted into a liquid that meets certain requirements and poured into a mold, cooled and solidified, and subjected to a treatment to obtain a casting (part or blank) having a predetermined shape, size, and performance. The basic process of the modern machinery manufacturing industry. The blank produced by casting has low cost, and it can show its economicality for parts with complicated shape, especially with complex inner cavity; at the same time, it has wide adaptability and good comprehensive mechanical properties. However, materials required for casting production (such as metal, wood, fuel, modeling materials, etc.) and equipment (such as metallurgical furnaces, sand mixers, molding machines, core making machines, falling sand machines, shot blasting machines, etc.) are more It can pollute the environment by generating dust, harmful gases and noise.
