Wire & Cable Connectors — 0.8–5.08 mm pitch held
Wire and cable connectors, also known as crimp terminals, crimp wire connectors, crimp cable connectors and eyelet terminals serve a simple but essential purpose of connecting electrical wires and cables to other parts and modules within the entire electrical system of vehicles, appliances, control systems and other electrical applications.

Performance
OPTIMAL CONNECTOR PERFORMANCE
Precision manufacturing of wire and cable connector parts is vital, as debris or a loose connection can create a gap or resistance between modules and cables or wires. These issues can lead to extreme heat during high current draws, causing the terminal and joining parts to corrode or even melt. When ISTAMPING supplies your wire and cable connectors, you can rest easy knowing they fit, conform and function as intended - leveraging 3D modeling and tooling simulation, sensor and inspection technology, and precision stamping techniques to produce high-quality, conforming parts repeatedly.
Secure connections are crucial for any electrically powered application. A subpar link between the parts of an electrical system can result in blown fuses and inoperability. Ensure your electrically driven application operates dependably and safely with high-quality wire and cable connectors from ISTAMPING.
We are a high-volume supplier of stamped metal parts and assemblies for use in a variety of industries, with deep expertise in electrical eyelet connectors, wire eyelet connectors and high-volume connector production for automotive and EV applications.

Manufacturing Process
How We Manufacture Wire & Cable Connectors
From drawing review to delivered parts — die design, stamping, plating and inspection records all owned in-house.
Connection Failure Analysis
A loose crimp or contaminated contact creates resistance that generates heat under high current - eventually corroding or melting the joint. We engineer every connector to maintain a stable, low-resistance path across its service life.
Design & Engineering
We review mating requirements, current rating and wire gauge to engineer progressive tooling that delivers consistent crimp quality and strip integrity at high speeds.
Progressive Die Tooling
Precision progressive dies are built in-house to form terminals, contacts and eyelets while holding tight tolerances run after run.
High-Speed Stamping
Connectors and eyelets are stamped in high volume with in-process monitoring on presses up to 300 SPM, holding ±0.005 mm precision.
Selective Plating
Reel-to-reel selective plating applies tin, silver, gold or nickel only where contact performance requires it - controlling cost while preserving conductivity.
Inspection & Quality Control
Camera vision and sensor technology inspect every part during stamping under IATF 16949:2016, supporting zero-defect, high-volume delivery.

In-House Tool Room
Made in Our Own Tool Room
Every progressive die behind our stamped parts is 100% in-house stamping tooling — design, machining, assembly and T1 trial all under our roof. That is why tooling issues get solved on the shop floor in hours, not by email exchange with an outside die shop.
±0.001 mm Achieved
Combined machining accuracy down to ±0.001 mm, Ra0.05 µm surfaces and Ø0.05 mm micro end mills for tight die features.
30 In-House Machines
30 die-making machines — wire EDM, CNC and precision grinding — keep every die build and repair on our own schedule.
2–5 Weeks for Stamp Dies
Typical stamping die delivery in 2–5 weeks, with T1 trials run on our own presses before you commit to volume.
One Accountable Chain
Self-designed progressive dies, machined in-house, run at 60–300 SPM with CCD inline inspection — no outsourced-die handoff where quality falls between suppliers.
INSIDE THE PLANT
Inside Our Stamping Line
Real equipment and inspection floor from our Dongguan plant — 25–110T high-speed presses, in-house tool room, and a CMM lab running first-article inspection on every program.
Engineering Support
Design-for-Manufacturability Support
Our engineers review your connector geometry at the quoting stage - material selection, crimp height, plating zones and tolerance relaxation - to lower tooling cost without compromising electrical performance. We also take over existing dies and optimize them for our high-speed presses.
FAQ
Questions Buyers Ask
Straight answers on materials, plating, supply format, quality and timing — send your drawing for anything specific.
What connector types do you stamp?
We stamp board-to-board, wire-to-board, inline and crimp terminals, eyelets and connector contacts in reel-to-reel strip or loose form, for automotive, EV and industrial harness applications.
What pitch sizes can you hold?
Our high-speed progressive tooling holds pitch ranges from 0.8 mm to 5.08 mm, with ±0.005 mm positioning precision on critical features.
Can you plate connectors selectively?
Yes. Reel-to-reel selective plating applies tin, silver, gold or nickel only on contact surfaces - preserving conductivity while controlling cost.
How do you prevent connection failures?
Every program starts with a feasibility review and run-at-rate study. In-line camera vision and sensors inspect each part, eliminating loose crimps and contamination that cause resistance, heat and joint failure.
