The Casting Difference

The RLM Investment Casting process offers many benefits over other types of casting processes including:

  • Low Initial Tooling Costs – Initial tooling costs averaged over the parts produced are often less than other manufacturing tool costs.
  • Elimination of Material Waste – Investment castings are cast to size, decreasing the amount of machining required.
  • Design Flexibility and Capability – Infinite choice of alloys and design flexibility for internal and external configurations. Virtually any shape or configuration can be investment cast, producing internally complex parts.
  • Design Enhancements – There are no draft requirements in the investment casting process.
  • Consistency – Our process gives a reliable and consistent product from order to order.
  • Close Tolerances – RLM’s typical linear tolerances can be plus or minus .005 in per inch. However, closer tolerances are frequently achieved on selected dimensions, depending on the alloy and configuration of the part.
  • Surface Finish Improvement – A surface finish of about 125RMS is standard for our investment castings.
  • Reproduction of fine details – Holes, bosses, and splines can be cast
  • Reduction of production costs – Costly machining operations can often be eliminated.
  • Reduction of assembly operations – Several parts can be made as a single casting, reducing assembly and handling costs.

As a general rule all ferrous and non-ferrous materials can be investment castings. Check our Alloy Selection Guide for details.
Investment casting may seem more expensive than other forging methods, but it also requires less secondary machining. RLM focuses on creating quality products, and can turn multiple piece projects into single piece projects. We think outside the box to create smarter and more efficient castings.
