Investment Casting Expertise
We specialize in custom high-precision investment casting processes, each tailored to your part’s complexity, size, and production goals. Here’s how these techniques deliver value:
Low Wax Investment Casting
Uses wax patterns and ceramic shells to achieve precise, detailed castings. Suitable for complex shapes with tight tolerances and minimal finishing needs
Shell Mold Investment Casting
Applies heated patterns and resin-coated sand to create strong, accurate molds. Ideal for medium parts needing dimensional stability and clean surface finish.
Vacuum Investment Casting
Performs casting in vacuum to avoid oxidation and trapped gases. Best for high-purity alloys like titanium, enhancing fatigue life in demanding fields.
What is Investment Casting?
Investment casting—also known as lost wax casting—is a precision metal forming method that uses expendable wax patterns to create high-accuracy ceramic molds, enabling the production of near-net-shape metal parts with complex geometries and exceptional surface quality.
A key advantage of this technique is its ability to work with a broad range of specialized materials—from corrosion-resistant alloys for marine environments to biocompatible metals used in dental and medical applications—helping engineers meet strict performance and regulatory standards. Its consistency in dimensional accuracy makes it ideal for both small-batch customization and high-volume production, often with little need for secondary machining.
Moreover, investment casting excels at producing intricate details, thin-walled sections, and internal cavities that are difficult or impossible to achieve through other casting or subtractive methods. This makes it a preferred solution in precision-critical industries such as aerospace (turbine blades, engine housings), medical (implants, surgical tools), automotive (valves, pump components), and advanced industrial systems.

Investment Casting FAQs
Have questions about Investment Casting? We’ve compiled a list of frequently asked questions to help you understand our processes better.
Production runs take 15–30 days (includes wax pattern creation, ceramic shell building, and casting). For prototypes or low-volume parts, rapid investment casting with 3D-printed wax patterns can shorten lead time to 7–14 days.
Both! We accept 3D models (STL, STEP, IGES) and work with your existing designs. Our engineering team also offers free design reviews to optimize geometry for investment casting—like adjusting wall thickness or gating to improve precision and reduce waste.
We support batches from 1 unit (prototypes) up to 500,000 units annually. Our process scales efficiently—whether you need a single functional prototype or high-volume production.
Yes. We offer in-house CNC machining, grinding, and polishing to meet tight tolerances. We also integrate surface treatments like passivation, anodizing, or electroplating for a turnkey solution.
We specialize in stainless steel (304, 316, 17-4 PH), aluminum alloys (A356, 6061), titanium (Ti-6Al-4V), nickel superalloys (Inconel 718), and copper alloys (bronze, brass). Each material uses tailored process parameters to maximize performance.
Investment casting is better for complex geometries (thin walls, intricate details), tight tolerances, and smooth as-cast finishes. Sand casting is more suited for larger, less detailed parts or lower-cost, high-volume production of simpler shapes.
