DFM for Rivets: Integrate Fasteners Early in CAD
Did you know that 80% of manufacturing costs are determined during the design phase? For design engineers, this means that decisions made at the CAD stage can make or break production efficiency. One of the most overlooked but critical factors in this process is fastening.
When it comes to fastening in digital design, rivets play a pivotal role. Ignoring rivet compatibility until late in the process leads to costly redesigns, tooling issues, or failed assemblies. At Rivetwise, we believe that design for manufacturing rivets should start in CAD not on the shop floor.
Why Fastener Integration in CAD Matters
Too often, fasteners are treated as afterthoughts. But if you’re designing for industries like automotive, aerospace, or construction, fasteners such as rivets influence structural integrity, assembly time, and material compatibility.
By incorporating rivets in CAD design from the outset, you ensure that every component aligns with the realities of manufacturing. This includes considerations like hole dimension for rivets, material stack-up, and access for tooling—all vital to streamline the transition from digital to physical.
Key Considerations for Rivet Integration in CAD
Here’s a practical breakdown for ensuring fastener compatibility during the design phase:
1. Grip Range Matters
Your selected rivet must match the combined material thickness. Rivets have a specific grip range and exceeding it can cause improper setting or structural failure. Always verify your material stack-up in CAD before finalising part geometry.
2. Hole Dimensions Must Be Precise
Designing the correct hole dimension for rivets is crucial. Undersized holes may prevent insertion; oversized holes weaken joint strength. Always use manufacturer specifications—Rivetwise offers downloadable 3D models of rivets with detailed dimensional data.
3. Spacing and Edge Distance
Poor spacing can lead to material tearing, while improper edge distances reduce the joint’s durability. A good rule of thumb? Edge distance should be at least 1.5× the rivet diameter, and pitch should be 3× the diameter.
4. Fastener Accessibility
Is there enough clearance for a rivet gun or tool? In tight assemblies, you might need to switch to a different rivet head or tool type. This is why early fastener integration in CAD is essential.
Tools and Resources to Simplify Design
At Rivetwise, we provide engineers with digital resources to make design for manufacturing rivets simple:
- 3D models of rivets for easy CAD drag-and-drop
- Material grip charts
- Fastener selection guides
- Technical support for bespoke fastening solutions
When you integrate rivets in CAD design from the beginning, you reduce risk, increase efficiency, and improve product performance all without surprises in production.
Fastening isn’t just a final step. It’s a strategic part of your product design. Embracing fastener integration early specifically with rivets in CAD design helps you move faster, smarter, and with fewer costly errors.
