This directory lists 56 lost wax casting companies across the United States, from specialty aerospace foundries to general industrial investment casting facilities.
Buyers engage with lost wax casting suppliers to solve a range of pressing manufacturing challenges, including producing parts with intricate internal features, achieving near-net shapes to minimize expensive machining, and leveraging specialized alloys not easily fabricated by other means. The process excels where precise dimensional tolerances, fine surface finishes, and repeatable metallurgical integrity are paramount, especially for components that are too complex or costly to machine from billet, or where thin walls and complex geometries, common in medical and aerospace, are required.
The lost wax casting landscape features diverse supplier types. Some specialize in specific materials like superalloys or titanium, catering primarily to aerospace and defense, often holding advanced certifications like AS9100 and NADCAP. Others focus on high-volume production of industrial parts using common steels and aluminum, prioritizing cost-efficiency and lean manufacturing. There are also smaller, more agile shops ideal for intricate, lower-volume runs or quick-turn prototypes, offering greater flexibility but potentially less extensive in-house post-processing capabilities.
When approaching lost wax casting companies, buyers should arrive with detailed 3D CAD models, material specifications (including specific alloy grades like 17-4 PH or Inconel 718), and clarity on critical dimensions and tolerances. Suppliers expect clear understanding of expected annual volumes, a target price point (even if it's a rough estimate), and any specific inspection or testing requirements. Providing clear end-use application details can also significantly aid suppliers in offering relevant DFM advice and process recommendations.
A notable trend in the lost wax casting industry is the increasing integration of automation, particularly in the wax room and ceramic shell building processes, to improve consistency and reduce labor costs. Additionally, there's a growing demand for suppliers offering advanced post-casting operations in-house, such as sophisticated CNC machining, heat treatment, and non-destructive testing (NDT) like X-ray or fluorescent penetrant inspection, to provide a more complete, single-source solution.

For a new lost wax casting project, expect initial lead times to range from 8 to 20 weeks. This primarily covers the design and fabrication of the wax injection tooling, which is a significant upfront investment, followed by the first article inspection (FAI) and approval process. Factors influencing this include part complexity, the number of cavities in the wax tool, material availability (especially for exotic alloys), and the foundry's current backlog. Subsequent production runs for approved parts will be much shorter, typically 4-8 weeks, depending on the casting process cycle and secondary operations.
The wax injection tool is absolutely critical as it defines the precise geometry of your wax pattern, which directly dictates the final cast part's dimensions and features. You generally cannot reuse tooling designed for other processes (like plastic injection molding) for lost wax casting due to differences in material shrinkage rates (wax vs. plastic), tool material requirements, and ejection mechanisms. Even if you have an existing investment casting wax tool, its condition, the original foundry's process parameters, and design for specific ceramic shell buildup can vary, making a thorough evaluation by the new supplier essential before committing to its use.
Beyond the basic casting, several post-casting operations are often necessary. These commonly include gate removal (sawing, grinding, or abrasive blasting), heat treatment (to achieve desired mechanical properties), straightening (to correct any distortion during cooling), and various machining operations (to meet tighter tolerances on critical features). Surface finishing like shot blasting, polishing, or electro-polishing may also be required. For critical parts, non-destructive testing (NDT) such as X-ray, liquid penetrant inspection, or magnetic particle inspection is often mandated to verify internal integrity and surface condition.
