electrical pins
Built for consistent alignment, fit, and electrical connection.
Gromax manufactures precision stamped pins for connectors, sensors, controls, molded assemblies, and other electrical connections. We review material, geometry, plating, and assembly requirements to support repeatable production.
part examples
Stamped pin examples for your application:
Connector Pins
Flat or formed pins with controlled mating geometry and retention features.
Sensor Pins
Precision pins that connect sensing elements to surrounding electronics.
Control & Switch Pins
Conductive pins for electrical connections within controls and switching assemblies.
PCB Termination Pins
Stamped pins with solder tails designed for board insertion and positioning.
Insert-Molded Pins
Pins with locating and retention features for integration into plastic housings.
Formed & Offset Pins
Bent or stepped pins that connect interfaces at different positions or heights.

part design essentials
Pin reliability depends on material, geometry, finish, and mating fit.
Mating Geometry & Alignment
Pin width, thickness, straightness, tip shape, and position must suit the mating interface.
Material & Thickness
- Conductivity, stiffness, formability, and retention requirements guide material selection.
Retention & Molded Features
Barbs, shoulders, holes, and locating features affect housing retention and positioning during molding.
Bends & Offsets
Bend radius, grain direction, springback, and feature spacing influence repeatable geometry.
Edges & Plating
Burr direction and finish requirements must account for insertion, contact surfaces, corrosion, and solderability.
from DfM to Production
Gromax supports stamped pin programs from drawing review through repeatable production.
Part & DfM Review
Review the drawing, mating requirements, material, tolerances, plating, and production volume.
Progressive Die Design & Build
Develop tooling for the required piercing, blanking, forming, and related operations.
Precision Stamping
Establish a production process around critical pin dimensions and formed relationships.
Plating & Secondary Operations
Incorporate finishing and additional processing into the production plan.
Production Support
Support ongoing programs with tool maintenance, process review, and corrective action.
quality & assembly fit
Inspection should verify the features that determine whether the pin fits and functions in your assembly.
Pin Geometry
Width, thickness, straightness, and tip condition.
Formed Features
Bend angles, offsets, and retention-feature locations.
Spacing & Alignment
Pin positioning while connected to a carrier.
Edges & Plating
Burr direction and specified plating coverage and thickness.
Assembly Fit
Fit with mating connectors, boards, or molded housings.
Gromax checks critical dimensions using standard measurement, fixtures, or custom gaging and reviews your certification, traceability, and inspection documentation needs.
