Today’s manufacturers demand faster and more complex casting solutions. To answer that challenge, Kimura is your “single-source” solution for the design, production and delivery of rapid prototype (RP) castings and small lot production castings. Our engineers work closely with you to develop and finalize your designs. Raw castings are produced with zero defects in just 5 days — ready for immediate shipment to your facilities in North America and worldwide.
Rapid Prototype and Small Lot Production
Precision Iron, Cast Steel and Specialty Alloy Castings
Use of 3D printing technology for rapid prototyping is commonplace today. But to make it truly effective for engineers and other buyers who need high precision, high complexity castings on demand—either a few RP castings or highly specialized castings in relatively small numbers —Kimura Foundry developed its own proprietary technologies.
The result: once design is completed, it takes just five days to produce molds, cast the parts, perform finishing and final inspection. This may be followed by machining operations. Castings can be made from Gray Iron, Ductile Iron, Ni- Resist, Stainless Cast Steel, Aluminum and Other Specialty Alloys. They can feature:
- Highly complex shapes
- Wall thicknesses as low as 1.5mm
- Dimensional accuracy ±0.5mm
- Internal cooling structures for castings
- Exceptionally smooth surfaces and defect free castings
Kimura produces castings to the highest global standards because of its more than 90-year tradition of best foundry practices combined with modern engineering, IT and its patented intellectual property.
Its focus has been on three fronts:
- USA and Japan patents on Kimura’s development of artificial sand that creates molds free of veining, burrs and other defects—and significantly lowers production costs.
- Sophisticated pouring and cooling standards that ensure uncompromised product integrity.
- Use of the latest Magma simulation software which tracks all aspects of pouring, solidification and casting quality.
Kimura’s RP castings are designed produced on the company’s four ExOne 3D printers
Total production costs are reduced, making RP and small lot castings very competitively priced.

Delivery of RP and small lot production castings has been reduced by 8x versus traditional casting. Design to production to delivery times now stand at just a few weeks. Faster than competitors in Europe and the USA.
Because of Kimura’s rapid delivery, quality and price combination, sales in Japan have grown dramatically.
