assembly fixtures
For stamped parts that need controlled fit, alignment, and repeatable build results.
When a stamped part needs to seat, align, retain, contact, or interface with another component, the assembly method can affect the final result just as much as the part itself.
Gromax builds assembly fixtures that help control how stamped parts are positioned, supported, inserted, retained, or checked during assembly — helping teams reduce variation, improve throughput, and catch fit issues before they reach the customer.

makes sense
Parts Are Hard to Align by Hand
Small stamped contacts, clips, terminals, shields, and inserts can be difficult to position consistently. A fixture helps locate the part and mating component before force is applied.
Assembly Results Vary by Operator
If one operator gets a clean fit and another struggles with alignment, seating, or retention, the process likely needs better control.
The Part Can Bend During Assembly
Thin stamped features, spring arms, tabs, and plated contacts can distort if they’re pushed, pressed, or handled incorrectly. A fixture helps support the part during installation.
Insertion Force Needs to Be Controlled
Some parts need a consistent push direction, stop position, or seating depth. A fixture helps guide the motion and reduce damage from side loading or overtravel.
The Part Fits on the Print but Fails in Build
A stamped part may meet dimensional requirements but still create assembly problems if the process doesn’t control alignment, stack-up, or mating engagement.
Production Needs a Faster Assembly Method
A fixture can help operators load, position, and assemble parts more quickly without relying on hand feel or repeated adjustments.
Retention or Engagement Needs Confirmation
Clips, tabs, lances, spring arms, and contact features often need to snap, seat, or engage correctly. A fixture can help confirm the assembled condition.
First Article or Launch Builds Need Support
During launch, prototype builds, PPAP, or customer validation, a dedicated fixture helps prove that the assembly method is controlled and repeatable.
Rework or Scrap Is Coming From Assembly Damage
Bent contacts, scratched plating, misaligned tabs, and poor seating are often process-related. A fixture can reduce handling damage and improve consistency.
The Current Fixture No Longer Matches the Part
Design changes, worn tooling, or process updates can make an older fixture unreliable. A fixture review can help bring the assembly method back in line with the part.

what
assembly fixtures
can support
Controlled Part Location
A fixture holds the stamped part and mating component in the correct position before assembly starts
Repeatable Insertion
Guided motion, hard stops, and support surfaces help operators assemble parts with consistent direction, depth, and seating.
Alignment and Stack-Up Control
A fixture can help manage how stamped parts, molded components, hardware, or mating features come together during the build.
Contact and Retention Features
Assembly fixtures can support delicate tabs, lances, clips, spring arms, and contact beams so they engage without being distorted.
Production Floor Assembly
Operators can use fixtures at the press, bench, or assembly station to build parts faster and with less variation.
First Article and Launch Support
A dedicated fixture helps engineering, quality, and production teams prove the assembly method during prototype builds, launch, PPAP, or customer validation.
In-Process Fit Checks
The same fixture can often support a quick confirmation that the part is seated, retained, aligned, or engaged correctly.
Operator Consistency
A good fixture reduces hand placement, judgment calls, and assembly variation between shifts, operators, or workstations.
Quality Issue Review
A fixture can help isolate whether the problem is coming from the stamped part, mating component, assembly method, or tooling condition.
Whether you’re trying to improve part alignment, reduce assembly variation, protect delicate stamped features, control insertion force, or speed up a production build, we’re happy to take a look.
