Yes. That’s often a strong fit when a program needs tool transfer, requalification, and tighter process control without risking fit, molding performance, or production stability.
MOLDING INTEGRATED
Insert & Overmold-Ready Metal Components.
Insert-mold and overmold programs fail fast when stampings aren’t stable. If carriers twist, parts warp in plating, or datums shift under injection pressure, the mold stack misaligns—causing flash, scrap, and sensor misreads.
Gromax loops in molding and automation early—before steel is cut. We design carriers, pitch, and datums to your mold and plating windows so inserts load cleanly, seat properly, and hold spec shot after shot.
what we
BUILD
Progressive-die carriers with tie-bar strategy, downsets, and plating windows that survive clamp, heat, and flow.
Insert-Molded Terminals & Blades
Create robust electrical paths molded into thermoplastic housings for connectors, switches, and sensor bodies; eliminate secondary assembly.
Overmold-Ready Leadframes
Provide the electrical fan-out and mechanical skeleton inside overmolded sensor/connector packages; supports pick-and-place and singulation.
Insert-Moldable Press-Fit / Compliant Pins
Enable solderless or hybrid connections from a molded module into a PCB backplane while locking pins in the plastic body.
Mold-In Ground Tabs & Shield Frames
Provide chassis/PE ground and EMI containment integrated into plastic housings for modules and sensor covers.
Overmolded Busbars & Power Links
Encapsulated low-impedance conductors inside connector bodies, power modules, EV subsystems, and compact controllers for creepage/clearance control.
Mold-Integrated Latches, Springs & Retention Clips
Provide repeatable snap-fits and actuation forces molded directly into housings for modules, cartridges, and covers.

how we add
VALUE
Insert Location That Holds
Stamped inserts built to functional datums so they locate cleanly in the mold and stay aligned to critical plastic features.
Retention Features That Mold Right
Barbs, windows, locks, and anti-rotation details designed for handling, molding pressure, and repeatable in-part retention.
Flash- and Cosmetic-Sensitive Interfaces
Edge condition and shutoff-aware geometry developed to reduce plastic shaving, interface flash, and visible cosmetic issues.
Protected Contact Areas
Plating-aware stamped contacts and terminals designed to keep conductive surfaces intact through molding heat, flow, and handling.
Repeatability Over Long Runs
Tooling and inspection strategies focused on springback control, wear monitoring, and stable insert position at production volume.
Stamping Aligned to the Mold
CTQs, gaging, and inspection built around molding and assembly datums so the insert performs in the tool, not just on the print.
frequently asked
QUESTIONS
What stamped components are a good fit for insert molding or overmolding?
Stamped inserts, terminals, contacts, grounding clips, reinforcement frames, and shielding features are all strong fits—especially when location, retention, and interface control matter.
What design issues should be reviewed early on molding-integrated parts?
Focus on insert location to molded datums, retention features, edge condition at plastic interfaces, plating protection, and stack-up with mating parts. These details usually drive molding performance and assembly yield.
How do you control variation that affects molding performance?
We control CTQs tied to insert position, retention, and contact areas. That includes datum-based gaging, burr strategy, springback control, and tool wear monitoring to keep inserts stable over long runs.
What should we look for in a supplier for molding-integrated stamped parts?
Look for experience with insert-molded and overmolded programs, strong positional control, plating awareness, repeatable inspection, and documented change control.
What documentation can be supported for these programs?
Depending on the program, support can include FAI or FAIR, inspection reports, SPC, PPAP when required, and MSA or Gage R&R.
