FAQs: Casting Metalworking Services
When clients come to us for casting metalworking, they usually have a few burning questions regarding budget, timing, and scalability. Here is the breakdown of what you need to know before kicking off a project.
Cost Comparison: Die vs. Investment Casting
Choosing between a die casting foundry and investment casting services often comes down to volume and detail. High-pressure die casting requires expensive hardened steel molds but pumps out parts cheaply and incredibly fast. Conversely, the lost wax process (investment casting) has significantly lower upfront tooling costs but a higher per-piece price tag.
| Feature | Die Casting | Investment Casting |
|---|---|---|
| Tooling Cost | High ($$$) | Low to Medium ($$) |
| Part Cost | Low (Best for high volume) | Medium to High |
| Surface Finish | Good | Excellent |
| Volume Suitability | 5,000+ units | 100 – 5,000 units |
Standard Lead Times for New Tooling
Time-to-market matters. Because die casting molds must withstand extreme pressure and heat, machining them takes time—usually 8 to 12 weeks. However, if you are utilizing sand casting aluminum methods, we can often get tooling ready in just 2 to 4 weeks since the patterns are simpler.
- Simple Patterns (Sand/Investment): 3–5 weeks
- Complex Die Cast Tooling: 10–14 weeks
- First Article Inspection (FAI): +1 week after tooling completion
Low-Volume Prototyping Availability
We don’t just handle million-part runs. We offer rapid prototyping casting to validate your designs before you commit to expensive hard tooling. By using 3D-printed sand molds or soft tooling, we can produce OEM casting parts in low volumes (even 1–50 units). This approach bridges the gap between initial design and mass production, allowing for functional testing without breaking the bank.
