Sand Casting for Power Generation Equipment Applications

June 13th, 2023

Many components of power generation equipment perform best when produced in cast iron. It’s a metal that can dampen vibration, distribute heat, hold up to wear and withstand high loads. Impro sand casts an extensive range of components in iron

Creating Internal Cavities in Sand Cast Parts

May 19th, 2023

Cavities in parts made by sand casting, like valve bodies, pump housings, and engine blocks, are there mainly to channel, guide and hold fluids. They can also reduce finished part weight and save on material. In principle they could be

Sand Casting for Commercial Vehicle Applications

May 9th, 2023

Components used in commercial vehicles must have strength, toughness, and a little ductility. Good heat transfer properties and low density are bonus factors. These requirements push part designers to the family of cast iron alloys, and this is a metallurgy

The Role of Binders and Resins in Sand Casting

March 23rd, 2023

Sand casting is a process where sand forms a mold that holds molten metal as it cools and solidifies. It’s also used for the cores that create hollow regions inside the cast parts. Sand grains must stick together to create
