Designing functional sheet metal enclosures is challenging enough without budget surprises. Shockingly, 30% of manufacturing costs are locked in during design phase according to Industrial Design Society studies. Many engineers overlook simple optimization opportunities that compound savings.
Over-specifying material thickness is incredibly common. We recently redesigned a control panel reducing gauge from 14 to 16 without compromising durability. This simple change cut material costs by 18%.
| Factor | Aluminum | Steel |
|---|---|---|
| Material Cost | Higher | Lower |
| Machining Cost | 30% faster | Standard |
| Corrosion Resistance | Excellent | Requires coating |
| Weight Impact | 40% lighter | Heavier |
Interestingly, aluminum often wins for enclosures despite higher material costs due to reduced secondary processing.
Complex bends require multiple operations. Our team discovered reducing bend directions from 5 to 3 decreased production time by 25% in a 2025 HVAC enclosure project. Simple adjustments like consistent bend radii matter tremendously.
Avoid designing sharp internal corners! They require specialized tooling and increase costs by up to 40%. Always maintain minimum bend radii relative to material thickness.
Traditional prototyping burns budgets fast. Instead, consider:
Surprisingly, skipping physical prototypes entirely isn’t recommended. Balance is key.
□ Standardized hardware throughout design
□ Minimum 2x material thickness between holes/edges
□ Consistent bend allowances across parts
□ Eliminated unnecessary surface treatments
□ Confirmed manufacturability with partner
Q: How much can DFM reduce enclosure costs?
A: Proper Design for Manufacturability typically cuts 15-30% off production expenses.
Q: What’s the most overlooked cost factor?
A: Shipping weight! Lightweight designs save repeatedly throughout product lifecycle.
Q: When should I consider custom tooling?
A: Only for production runs exceeding 5,000 units or critical functionality requirements.
