About Us — Est. 2010
A Manufacturing Partner Behind Every Connection
Wenzhou Hehui Electric Co., Ltd. (HEH) — we design and manufacture automotive connectors, terminals and cable accessories: 371 models, 1–66 pins, every stage produced inside one plant in Yueqing, Wenzhou.
- Founded 18 March 2010
- Yueqing — China’s electrical industry hub
- Import / export licensed manufacturer
Who We Are
One Factory. Full Control.
We started on 18 March 2010 in Yueqing, Wenzhou — one of China’s densest clusters for electrical components and connectors. From day one we narrowed our focus: build reliable automotive connectors and terminals at a competitive total cost, and nothing else.
Most suppliers in this industry assemble. We manufacture. Rather than buying housings from one workshop and terminals from another, we built the whole chain in-house: mold R&D, plastic injection molding, metal stamping, final assembly and inspection, all on one site.
That choice is the reason buyers stay with us. When every stage sits under one roof, dimensional accuracy, material quality and delivery dates are ours to control — not something we have to chase through third parties. Today we are a licensed import/export manufacturer serving buyers of on-board vehicle systems, low-voltage electrical equipment and instrumentation worldwide.
We inspect incoming material, run in-process patrol checks (IPQC), and test dimensions, conductivity, sealing and temperature resistance on finished parts.
We work from your drawings — including drawing modification and full Engineering Change Notice (ECN) execution through to production.
We are a fully registered manufacturer with import/export qualification, so your orders clear customs without improvised paperwork.
Our standardized production and experienced export team give you fast, reliable quotations and repeat supply.
Why We Don’t Outsource
Four Stages. One Roof.
It would be cheaper to buy housings from one workshop and terminals from another. We don’t, and here is what that decision buys you.
Mold R&D
We design and cut molds in-house, so a new model or a cavity change does not wait in someone else’s queue.
Injection Molding
Our own injection lines run connector housings and insulating parts, with the mold and the machine in the same building.
Metal Stamping
We stamp terminals and contacts to the dimensional tolerances your drawing actually specifies — not to the nearest available grade.
Assembly & QC
We assemble and inspect at the end of the same line, so what we measure is what ships.
Why Three Gates, Not One
Quality Is Cheaper Before Shipment
A connector carries current and lives in a harsh environment. A single final inspection can only tell you that some parts are bad — it cannot tell you where the problem started.
Incoming Inspection
We check resin and metal strip against specification before it goes onto a machine.
In-Process Patrol (IPQC)
Our patrol checks keep molding, stamping and assembly inside tolerance during the run, not after it.
Final Testing
We verify the key indicators on the finished part before shipment — dimensions, conductivity, sealing and temperature resistance.

Inside the Plant
Machines Feed. People Decide.
Our assembly hall runs on automatic vibratory-bowl feeding: terminals and housings are sorted, oriented and fed to the assembly station by machine, which is what keeps cycle time and orientation repeatable across a production run.
The operators you see are not there to feed parts by hand. They are there to watch the process, pull the sample, and stop the line when something drifts. Automation gives us consistency; people give us judgment. We keep both.

How We Work Together
From Your Drawing to Repeat Supply
Most of our business is not an off-the-shelf part number. It is a buyer’s drawing that has to become a part — and then keep being that exact part, order after order.
Drawing or Requirement
Send a drawing, a sample, or just the application: pin count, current, mating part and environment.
Feasibility
Our engineers check the tolerance and material against our own molds and dies, then come back with a straight answer.
Quotation & Sample
We quote against your volume and send samples, so you can check fit before committing.
Engineering Change
If the part has to change, we run it as a formal ECN — drawing revised, tooling updated, revision recorded.
Production & Supply
We produce to the agreed revision, and match repeat orders to the approved sample.
Buyers rarely hand over a finished drawing. Cavity layout, wall thickness and terminal position usually need adjusting to be manufacturable — or to fit a harness that changed after the first sample. We handle that as a document, so the revision you approve is the revision we build.
What Drives Us
Mission, Vision & Spirit
Three statements we wrote for ourselves, kept in the original Chinese because the English is only an approximation. They are our founder’s own commitments — still how we run the plant.
