Rapid Prototype & Small Lot Production Castings

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 90-year tradition of best foundry practices combined with modern engineering, IT and its patented intellectual property.

Its focus has been on three fronts:

  • Japan and USA 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 Artificial Sand Kimura Foundry has innovated on many fronts of casting production including artificial sand

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.

Sand Recylicing Costs

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.

Delivery times reduced

Because of Kimura’s rapid delivery, quality and price combination, sales in Japan have grown dramatically.
