What We Actually Solve

Tooling That Controls the Process (Not Just the Part)

Do you struggle with unreliable part positioning, slow assembly, or quality issues that “come and go” from one shift to the next? In most cases, the problem doesn’t start with machining or assembly—it starts with how the part is located, restrained, and released.

Rapidaccu designs and manufactures process-control fixtures and jigs that turn unstable steps into repeatable outcomes. With an engineering-led team and hands-on experience—especially in automotive production tooling, semiconductor fixtures, and optical/photonics alignment tooling—we help you stabilize your line and reduce rework.

Our fixtures are built to:

✓
Lock geometry before variation begins
✓
Control deformation caused by force, heat, and repetition
✓
Shorten cycle time without sacrificing accuracy
✓
Make inspection results repeatable and defensible

If your quality depends on “who’s on shift,” your process isn’t controlled yet. We build the tooling that makes it controlled.

Custom Tooling FAQ

How does Rapidaccu ensure measurement correlation?

For metrology fixtures, we align datums directly with your inspection plan. By enforcing a “Seat First, Constrain Second” logic, we eliminate mechanical bias between different operators and sites.

Can you handle engineering changes (ECO) after the build?

Yes. We utilize modular swappable nests and contact interfaces. This allows us to iterate revisions cost-effectively without requiring a full fixture rebuild.

What is your typical lead time for production fixtures?

Standard leads range from 4-8 weeks depending on complexity. We provide a full quotation with lead time and risk assessment within 24 hours of receiving your drawings.
