Assembly and Testing - Riganelli Engineering

Why it matters

Where everything comes together

Assembly and testing is where everything comes together. Individual machined, printed, molded, and fabricated parts are assembled into a complete, functional product - ready to be held, used, and tested under real-world conditions.

By assembling the product ourselves - using parts fabricated in-house alongside purchased or client-supplied components - we gain firsthand insight into the assembly process. We see which steps are difficult, which tolerances are too tight or too loose, and where the design could be simplified for production.

Complete functional prototypes

Bringing together custom and purchased mechanical and electrical components into a fully assembled product you can hold, operate, and demonstrate. Complete prototypes give you the confidence to make decisions about the design and the path to production.

Design for assembly improvements

Every assembly teaches us something - whether it's reducing part count, changing a fastener type, adjusting a clearance, or resequencing the assembly order. These improvements reduce assembly time and production costs at scale.

Real-world validation

Functional testing under real conditions catches issues that bench testing individual components cannot. How does the product feel in use? Does the mechanism operate smoothly? Do the electronics perform correctly inside the enclosure?

Faster iteration cycles

When testing reveals an issue, the engineering and prototyping teams are right here to update the design, remake the part, and reassemble - often the same day.

How we can help

Component Integration

We bring together parts fabricated in-house - machined, 3D printed, laser cut, injection molded, and soldered - with purchased components such as fasteners, bearings, seals, motors, and electronics, as well as any client-supplied existing parts.

Full Product Assembly

We build the complete product from individual components, following the intended assembly sequence. This step tests fit, clearances, fastener access, and assembly order - identifying any issues that only become apparent when you're physically putting the product together.

Functional Testing

The assembled prototype is put through its paces - testing performance, durability, ergonomics, and function against the product's specifications and intended use conditions. Testing is tailored to what matters most for your product.

Design for Assembly Feedback

Every assembly reveals insights. We document opportunities to reduce part count, simplify assembly steps, adjust tolerances, and make the product easier and cheaper to build at scale. These findings are incorporated into the next design revision.

Reporting and Iteration

Test results and assembly observations are documented and reported back to you and our engineering team. The report covers what worked, what didn't, and what we recommend changing. Findings drive the next design iteration - and the cycle repeats until the product is ready for production.
