When you’re ready to bring your concept to life, one of the first questions is always the same: How much will it cost to custom-manufacture my design? At Mettler Design, we understand how crucial accurate, optimized, and budget-friendly design decisions are—especially for engineers and teams moving quickly from prototype to production.

Using the right materials, finishes, and fabrication methods dramatically impacts overall cost. Fortunately, strategic choices early in the design process can significantly reduce expenses while maintaining top-tier quality.

Below are eight smart, practical tips to help you minimize costs when creating custom sheet metal enclosures, parts, and panels.

1. Stick to Stocked Materials for Maximum Savings

Choosing from stocked materials and standard thicknesses is one of the most effective ways to reduce manufacturing costs. Because stocked materials are readily available, you avoid extended lead times and unnecessary sourcing fees. This approach keeps your project moving quickly and efficiently.

2. Choose In-House Finishes for Better Value

While some processes—like anodizing or tin plating—require third-party services, many finishes can be completed in-house. By selecting powder coating, brushing, chem film, or graphics done internally, you not only streamline workflow but also minimize extra outsourcing costs.

3. Select Cost-Effective Materials Smartly

If you’re budget-conscious, choose materials that balance durability with affordability.

• Most economical: 5052 Aluminum, Cold Rolled Steel
• Mid-range: Galvanneal
• More expensive: Copper, Stainless Steel

Material choice directly affects cost, so choosing wisely can significantly reduce your budget.

4. Use Cutouts Strategically

Cutouts are essential—but excessive cutouts dramatically increase machining time. Instead of hundreds of small holes, consider slots or perforated sheet metal. These alternatives reduce cost and minimize potential warping during fabrication.

5. Add Countersinks Only Where Needed

Countersinks enhance aesthetics and functionality, but adding them everywhere drives up cost. Place them only in positions where a flush surface is essential, such as front panels or areas with interference concerns.

6. Choose Fasteners Over Welding When Possible

Welding adds strength but also complexity and cost. If your design allows it, fasteners are a more economical option. When welding is required, using a combination of spot welding and fasteners can still deliver savings.

7. Mask Selectively to Reduce Finishing Costs

Masking protects areas from powder coating, but masking multiple zones can add up. Instead, request custom masking only where absolutely necessary—such as near specific fasteners or electrical contact points.

8. Increase Quantities for Better Unit Pricing

Mettler Design specializes in low-volume and prototype manufacturing, but ordering higher quantities always lowers the unit price. If you know you’ll need additional units after prototyping, a blanket order can offer even better long-term savings.

Conclusion: Plan Smart. Save More. Build Better.

Ultimately, cost-effective design is about making informed choices—materials, finishes, assembly methods, and quantities all play a crucial role. At Mettler Design, we help you move from idea to reality quickly by offering expert guidance, collaborative support, and fast turnaround times.
