CM International’s custom metal casting services include die casting, sand casting, investment casting, and other processes. Our resources allow us to offer customers high-quality products at competitive costs. Our parts size range from 25mm to 750 mm (1” to 30”), and are made to fit your specifications. Quick, reliable service is our priority. We offer a 12 week lead time for large order; and as a full-service manufacturer, we can provide complete logistics support, warehousing in the USA, inventory programs, feasibility analysis and other quality assurance programs. When necessary, we assist customers with light sorting and assembly needs. Plating and heating treatments are also a part of our value-added services.
We process a variety of metals and materials to meet customer needs and specifications:
CM International produces die casted parts from 1”-30” in size (12mm-750mm) and works with many materials. We offer a 12 week lead time for large orders and our tolerances are always to customer specifications based on the size of the part, with general tolerance per ISO 2768 /ASME Y14.5-2009.
Machining: Conventional Milling and Turning; CNC Machining and Turning.
Plating: Zinc Plating, Chrome Plating, Tin Plating, Nickel Plating, E-coating, Black Oxide, Anodize, etc.
Heat Treatments: Annealing, Normalizing, Tempering, Quenching, Induction Harding etc.
Die casting is a high-pressure casting process where molten non-ferrous metals are forced into a steel mold (die) to form complex, precise parts with excellent dimensional accuracy. It is ideal for mass production in industries such as automotive and electronics. Although it involves initial tooling costs, the process uses reusable dies, allowing for high production rates and tight tolerances, good for repeatability.
CM International's sand casting capabilities serve almost any industrial or commercial application. Most commonly, we work with the automative, hydraulic, railway, electronic, commercial, marine, and mining industries. Our part size capabilities range from 25mm to 750mm (1* to 30*), and are made to fit your specifications based on the size of the part, with general tolerance per ISO 2768 /ASME Y14.5-2009.
Machining: Conventional Milling and Turning; CNC Machining and Turning.
Plating: Zinc Plating, Chrome Plating, Tin Plating, Nickel Plating, E-coating, Black Oxide, Anodize, etc.
Heat Treatments: Annealing, Normalizing, Tempering, Quenching, Induction Harding etc.






Sand casting is a traditional metal casting method using molds made from compacted sand to form intricate shapes. It is one of the more versatile casting methods, but precision can be limited. It is valued for its flexibility, cost-effectiveness, and ability to handle high-temperature metals. Example parts made with sand casting are engine blocks or valve bodies.
CM International manufactures gravity casted parts for a wide range of industries, including, but not limited to, automotive, hydraulic, railway, electronic, and commercial. Common parts we manufacture with the gravity casting process include engine housing, brackets, cooling systems and large utility equipment. Our part size capabilities range from 25mm to 750 mm (1” to 30”). We offer general tolerance per ISO 2768 /ASME Y14.5-2009 and are headquartered in Chicago with manufacturing facilities in China.
Machining: Conventional Milling and Turning; CNC Machining and Turning.
Plating: Zinc Plating, Chrome Plating, Tin Plating, Nickel Plating, E-coating, Black Oxide, Anodize, etc.
Heat Treatments: Annealing, Normalizing, Tempering, Quenching, Induction Harding etc.



Gravity die casting also uses a mold (die) to form non-ferrous metals, but instead of a high pressure forcing the molten metal into the mold, gravity is only used to pour the molten metal into the mold. It creates stronger and larger products, but is only suitable for lower production volumes.
CM International produces investment casting parts from 1”-30” (12mm-750mm) in size, and works with many materials, including stainless steel, aluminum, carbon steel, iron, and zinc. We offer a 12 week lead time for large orders and our tolerances are always to customer specifications based on the size of the part, with general tolerance per ISO 2768 /ASME Y14.5-2009.




Investment casting, or lost-wax casting, is a precision metal casting process that creates intricate molds by coating a wax pattern with a ceramic shell, melting out the wax, and pouring molten metal into the resulting cavity. It's valued for its ability to produce complex geometries, thin walls, and excellent surface finishes for industries like aerospace, and medical parts. It tends to have higher mass production costs, but can be net cost effective due to the lower finishing costs needed.
