At Trustbridge, our Design for Manufacturability (DFM) services help you avoid expensive surprises and unnecessary delays by optimizing your part designs for the real-world constraints of production before a single tool is cut or part is made. Whether you're prototyping a new product, preparing for injection molding, or trying to reduce cost in an existing design, our engineers provide detailed, actionable feedback to align your design intent with the realities of machining, molding, casting, printing, and more.

We’ve supported hundreds of successful product launches across industries and we’ve seen what works, what fails, and what costs you time and money. Let us bring that insight to your design process.

Design for Manufacturability (DFM) Services: Optimizing Product Design For Efficient Manufacturing

Our DFM Services at a Glance

Tolerance and Feature Optimization

We evaluate every critical dimension and surface recommending changes to tolerances, wall thicknesses, hole sizes, and surface specs that reduce production risk without compromising function.

Eliminate overly tight tolerances that drive up cost
Align hole/pin sizing to standard tool sets
Ensure features are moldable, machinable, or castable as needed

Process-Specific Design Recommendations

Each manufacturing process has its own rules. We tailor your part to match:

CNC Machining: Avoid deep pockets, sharp internal corners, or tool-defying features
Injection Molding: Add proper draft angles, eliminate undercuts, and balance wall thickness
Sheet Metal: Standardize bend radii, adjust flange lengths, and design for nesting efficiency
3D Printing: Orient for strength, minimize support structures, and adjust for anisotropic behavior
Casting: Account for shrinkage, gating, parting lines, and post-cast machining needs

Material Compatibility Guidance

We help you select the right material based on:

Strength, stiffness, and durability requirements
Heat resistance, chemical exposure, or regulatory needs
Compatibility with your selected process (e.g., injection moldable vs. machinable)
Cost and availability in target markets

Design Review Reports

We deliver clear, structured feedback not vague suggestions. A typical DFM review includes:

Annotated screenshots of trouble areas
Specific geometry or tolerance changes
Manufacturing process notes
Suggested alternatives
Optional redesign services (upon request)

Whether you're sending us a STEP file, native CAD, or just a sketch we’ll help you move forward with confidence.

Who We Support

We serve design engineers, sourcing leads, and product developers across industries:

Startups who need full design support from concept to launch
Mid-sized OEMs with in-house design teams who need overflow capacity
Contract manufacturers looking to quote or revise customer-provided files
Sourcing teams inheriting incomplete or outdated CAD from legacy vendors
Inventors with a sketch or prototype that needs to go digital

Where DFM Fits in Your Product Lifecycle

Early Prototyping → Parts look great but don’t scale → Design review for production alignment

Mold/Tooling Design → Features require complex, costly tooling → Simplify design for lower-cost tools

Cost Reduction → High scrap rates or expensive features → Identify redesign opportunities

Supplier Transitions → New vendor can’t hold tolerances or lead time → Adjust specs to new vendor capabilities

Legacy Part Redesign → No files, or outdated design features → Rebuild and optimize with current tech

Why Trustbridge for DFM?

Cross-Process Expertise: Our team has worked across machining, molding, casting, and printing so we know how to design for all of them.

Connected to the Factory Floor: Our feedback reflects real-world vendor constraints because we also manage the suppliers.

Clear, Actionable Feedback: We don’t just say “this might be a problem” we show you what to change and why.

Outcome-Focused: Our goal isn’t just a cleaner CAD model it’s parts that run right the first time, at the right cost.

One Partner from Design to Production: Once your part is optimized, we can quote, prototype, and scale it through our manufacturing network.

Don’t Wait to Find Out What Went Wrong. Design It Right the First Time.
Our DFM reviews start at the earliest stages of development and can save you weeks and thousands of dollars down the line.
