ForceBeyond is a premier global investment casting supplier specializing in high-precision, near-net-shape components. Widely recognized as the lost-wax process, investment casting is the preferred manufacturing method for producing complex metal geometries with exceptional surface finishes and tight dimensional tolerances.
Operating under ISO 9001:2015 and AS9100 quality standards, our global foundry network delivers mission-critical custom investment castings to the aerospace, medical, energy, defense, and fluid power industries. From standard carbon steel investment castings to high-spec vacuum-cast Inconel 718 investment cast components, ForceBeyond provides scalable capacity for parts ranging from fractions of an ounce up to 200+ pounds.
Choosing between metal casting methods depends on geometric complexity, dimensional tolerance requirements, and required surface finishes. The comparison table below highlights why engineers select lost-wax investment casting for precision applications.
| Performance Specification | ForceBeyond Investment Casting | Standard Industrial Sand Casting |
|---|---|---|
| Surface Roughness (As-Cast) | 63–125 RMS (Smooth / Near-Net) | 250–500 RMS (Coarse) |
| Linear Tolerance Standard | ±0.005 in/in (ISO 8062 CT5–CT7) | ±0.030 in/in (Rough) |
| Minimum Wall Thickness | Down to 0.040 in (1.0 mm) | Minimum 0.180 in (4.5 mm) |
| Internal Geometry & Coring | Complex, Draftless Internal Cavities | Limited to Simple Draft-Angled Cores |
The investment casting process offers unmatched material versatility, accommodating virtually any ferrous or non-ferrous alloy. ForceBeyond provides high-performance metallurgy through both standard air-melt and specialized Vacuum Induction Melting (VIM) investment casting processes.
| Investment Casting Material Category | Core Alloys Poured | Key Features & Optimal Applications |
|---|---|---|
| Stainless Steel Investment Casting | 304, 316L, 17-4 PH, 2205 Duplex | Superior corrosion resistance and hygiene. Ideal for medical instruments, marine hardware, and high-pressure fluid valves. |
| Superalloy Investment Casting (VIM) | Inconel 718, Inconel 625, Hastelloy X | Extreme heat and fatigue resistance. Critical for aerospace engine components and industrial gas turbines. |
| Titanium Investment Casting | Ti-6Al-4V (Grade 5) | Unmatched strength-to-weight ratio. Used heavily in aerospace structural parts and biocompatible medical implants. |
| Carbon & Alloy Steel Investment Casting | 1020, 1045, 4140, 8620 | Excellent strength and toughness. Widely used for heavy machinery, automotive components, and industrial brackets. |
When complex engineering designs call for thin walls, intricate internal passages, and tight geometric features, precision investment casting regularly outperforms sand casting, forging, and direct CNC machining from solid billet.
ForceBeyond utilizes robotic shelling equipment and automated wax injection systems to maintain strict lot-to-lot consistency across all investment casting runs.
While near-net investment casting eliminates most metal removal, high-precision features still require finish machining. ForceBeyond provides a seamless Tier-1.5 single-source workflow to manage all secondary processing under one quality standard:
Sand casting uses a reusable wood or metal pattern packed into sand, making it suitable for massive, heavy parts but producing rougher surfaces (250–500 RMS) and loose tolerances. Investment casting utilizes ceramic slurry shells over sacrificial wax to achieve ultra-smooth finishes (63–125 RMS), linear tolerances of ±0.005 in/in, and thin walls down to 0.040 inches.
Depending on the alloy and geometry, precision investment casting can reliably produce wall thicknesses as thin as 0.040 inches (1.0 mm) for small geometries, while standard design guidelines target 0.060 inches to 0.125 inches.
Yes. We utilize 3D-printed wax or SLA patterns to build ceramic shells for rapid prototype pours. This enables engineering teams to validate physical cast alloys and fluid dynamics before committing to hard aluminum production tooling.
