Our aluminum investment castings offer precision and consistency whether you need a single prototype or production quantities. We handle everything from thin-wall components to complex shapes with tight tolerances, making sure your parts meet exact specs and quality benchmarks.
Design Freedom
Investment casting lets you create complex, thin-wall shapes impossible with sand or die casting. This means fewer parts, lighter components, and faster assembly.
Strength-to-Weight Ratio
Using alloys like A356 and A357, investment castings deliver strong parts that keep weight low—perfect for aerospace and automotive uses.
Cost-Effectiveness
For short runs and low-volume production, investment casting cuts waste and machining, saving time and money compared to die casting or machining from solid blocks.
In short, aluminum investment castings offer the right balance of precision, strength, and design flexibility—helping U.S.-based companies stay competitive with quality parts that perform.

Design Guidelines for Aluminum Investment Castings
When designing aluminum investment castings, keeping a few basic guidelines in mind can save time and cost while improving part quality.
- Draft Angles: Use at least 1–3 degrees of draft on vertical surfaces. This helps with easy removal of the ceramic shell and reduces damage during casting.
- Fillets: Add fillets or rounded corners instead of sharp edges. This strengthens the casting, reduces stress concentrations, and improves metal flow.
- Ejector Pin Placements: Plan ejector pins in areas that won’t impact critical surfaces or dimensions. Proper placement avoids marks on visible or functional parts.
- Parting Lines: Position parting lines where they’re least noticeable and easiest to machine or finish. Keep them on flat or low-stress surfaces when possible.
Following these tips will help ensure smooth production and yield strong, precise aluminum lost-wax castings that meet your specifications.
Контроль качества и тестирование
We take quality seriously with every aluminum investment casting we deliver. Our process includes thorough chemical analysis to ensure the alloy meets exact specs. Mechanical testing checks strength, hardness, and durability so your parts perform as expected.
Before full production, we provide инспекция первого изделия (FAI), to verify dimensions and features match your designs. Every casting undergoes visual inspection to catch surface defects and confirm finish quality.
Dimensional inspections take place using precise tools like CMM (Coordinate Measuring Machines) to ensure tight tolerances and consistency. This thorough approach guarantees your aluminum castings meet or exceed industry standards, ready for use in aerospace, automotive, medical, and other critical applications.
