stamped inserts for overmolding
Precision stamped inserts for molded and overmolded assemblies.
part samples
Stamped inserts for molded parts must do more than stamp cleanly. They need to stay put during loading and molding, keep their electrical or mechanical function, and fit the final plastic assembly.
Connector Inserts
Precision stamped contacts or terminals molded into connector housings for electrical connection, retention, and mating performance.
Mold-Loaded Terminals
Stamped terminals designed for manual or automated placement into molds before the plastic molding process.
Sensor Inserts
Stamped conductive or structural inserts used in molded sensor housings where contact alignment, stability, and repeatability are critical.
Leadframe-Style Inserts
High-volume stamped leadframe-style parts used in molded electronic assemblies that need tight contact spacing and consistent geometry.
Overmolded Contacts
Stamped contacts designed to hold position, conductivity, and contact shape through the molding process.
Switch Inserts
Stamped conductive inserts used inside molded switch assemblies to provide electrical pathways, contact surfaces, or mechanical retention.
Grounding and Conductive Inserts
Stamped inserts used to provide grounding, shielding, current transfer, or electrical continuity inside molded electromechanical products.
Medical Cartridge Inserts
Precision stamped inserts used in molded diagnostic, monitoring, sensing, or fluid-management components where small features, clean geometry, and repeatability matter.

common applications
Stamped inserts are used where insert position, molded-in retention, electrical performance, durability, and production consistency directly affect the finished assembly.
Battery Terminal Fuse
Stamped terminals, contact plates, grounding features, and formed current-carrying members are used in molded battery and power-management components to support current flow, circuit protection, and compact electrical routing.
Automotive Sensor Connector Housing
Stamped inserts and terminals are used in molded sensor housings to provide stable signal, power, and ground paths while holding the contact position inside the plastic body.
Overmolded Temperature Sensor Probe
Overmolded stamped inserts, terminals, and contact features help maintain sensor position, electrical continuity, strain relief, and sealing performance in vehicle sensor assemblies.
Diagnostic Test Cartridge
Precision stamped inserts may support sensing interfaces, electrical contact points, retention features, and compact assembly details inside molded medical diagnostic components.
22 mm Pushbutton Switch
Stamped contacts, spring/contact elements, terminal features, and retention details are used in molded industrial pushbuttons to support switching function, wiring connection, contact alignment, and long service life.
Overmolded Switch Assembly
Stamped contacts, domes, terminals, and retention features are positioned inside molded or sealed switch bodies to support tactile response, electrical continuity, actuator alignment, and long-term switching performance.

Insert Location Must Be Controlled
Stamped inserts may need tight control of contact position, spacing, height, flatness, or alignment so they locate correctly inside the molded part.
The Part Needs a Carrier Strip
Carrier strips can help with plating, handling, mold loading, automated feeding, inspection, packaging, and maintaining orientation through production.
Retention Features Matter
Tabs, holes, slots, embossments, coined areas, undercuts, barbs, or formed features may be needed to help the insert lock into the molded plastic.
Burr Direction Affects Molding
Burrs and sharp edges can affect sealing surfaces, plastic flow, flash, insert seating, molded-in retention, operator handling, or downstream assembly.
Plating Must Survive the Process
Tin, nickel, silver, gold, and other finishes may need to support conductivity, solderability, corrosion resistance, wear, and compatibility with molding and handling.
High-Volume Production Is Planned
Progressive tooling is often a strong fit when the program requires repeatable inserts, consistent orientation, stable carrier design, and ongoing production supply.
Whether you’re developing a new overmolded insert, sourcing an existing molded-in terminal, reviewing insert movement or flash issues, or qualifying a second source, we’re happy to take a look.
