Complex parts such as hydraulic pumps, motors, and valve housings are manufactured with high-precision cores to ensure internal geometry accuracy.
High-Precision Cold Box Cores for Complex Castings
Core boxes play a critical role in the casting process. Each is designed to suit different casting requirements and production volumes.
Our Cold Box Core Technology and Capabilities
FerroCastings is equipped with 15 cold box core makaing machines capable of producing from 0,4 lbs to 100. This allows us to design and manufacture core boxes tailored to the gray iron casting and ductile iron casting types our customers require.

FAQ
Which core-making technology do you use for complex internal geometries?
We specialize in Cold-Box core-making technology. This process is ideal for producing high-precision cores with excellent dimensional stability, allowing us to cast complex internal channels for hydraulic valves, engine blocks, and pump housings.
How do you ensure the quality and strength of the sand cores?
We utilize automatic sand preparation systems that precisely control resin and catalyst ratios. Each batch is tested for tensile strength and permeability to prevent casting defects such as gas porosity or core breakage during the pouring process.
Do you offer specialty coatings for cores?
Yes. To ensure a superior internal surface finish and prevent sand burn-in, we apply water-based or alcohol-based refractory coatings via dipping or spraying, depending on the specific metallurgical requirements of the part.
