SECONDARY OPS & ASSEMBLY
Parts That Arrive Finished and Ready for Your Line
Downstream operations like plating, tapping, finishing, and handling can introduce burrs, variation, or damage after stamping.
Gromax coordinates these processes within a controlled workflow to deliver parts finished, inspected, and ready for production, reducing quality risk and supplier handoffs.
Deburring & Edge Conditioning
Controlled deburring and edge conditioning, including tumbling or mechanical finishing where appropriate, to remove burrs and sharp edges from stamped components.
Improves part safety, assembly fit, and cosmetic quality, while preventing downstream handling damage.
Precision Tapping & Machining
Secondary machining processes including tapping, drilling, reaming, countersinking, and chamfering to produce threaded or precision features not achievable in the die.
Ensures accurate threaded and functional features, reducing assembly issues and improving product reliability.
Coining & Feature Sizing
Coining or sizing operations used to refine critical surfaces, thickness, or interface geometry after stamping.
Improves fit-critical interfaces and dimensional stability for parts used in assemblies with tight tolerances.
Part Marking & Traceability
Laser marking, stamping, or identification methods used to apply part numbers, date codes, or traceability information when required.
Supports product traceability, lot tracking, and regulatory compliance for controlled programs.
Plating & Surface Finishing Coordination
Managed plating and finishing services including tin, nickel, gold, and silver, with RoHS-compliant options where required.
Delivers consistent corrosion protection, conductivity, and cosmetic finish while simplifying supplier coordination
Mechanical Assembly & Riveted Subassemblies
Integration of stamped parts into mechanical subassemblies, including riveted assemblies and related fastening methods.
Reduces customer assembly steps and supplier complexity, delivering components ready for installation.
Welded Assemblies
Welded assembly operations managed as required based on program needs and component design.
Enables multi-part stamped assemblies to be delivered as complete components, reducing internal fabrication requirements.
Kitting & Production-Ready Packaging
Custom kitting, orientation, and packaging designed to support efficient material handling and line-side builds.
Helps improve assembly speed, inventory control, and production efficiency.
frequently asked
questions
What secondary operations can Gromax support?
We support a range of secondary operations, including tapping, machining, deburring, plating coordination, and part-specific finishing based on the application.
Can you assemble multiple components into a finished part or subassembly?
Yes. We support assembly of stamped components and related hardware to deliver finished parts or subassemblies ready for the next step.
Can you help reduce handling and assembly issues?
Yes. We review the part and assembly flow to identify ways to improve fit, reduce extra handling, and simplify downstream assembly.
Can Gromax manage secondary operations and assembly in one program?
Yes. We can manage stamping, secondary operations, and assembly together to simplify sourcing and improve coordination.
How do secondary operations and assembly affect cost and lead time?
Cost and lead time depend on the number of steps, part complexity, outside processing, and packaging requirements. We outline those factors clearly during quoting.
Can Gromax support repeat quality for assembled parts?
Yes. We use controlled processes and inspection steps to support consistent quality across both component production and final assembly.
