Fine pitch, thin sheet, high-speed production, backed by die accuracy.
Connectors used in smartphones, PCs and vehicles keep getting smaller and denser, which means narrower terminal pitch and thinner material. Since terminal dimensional variation directly affects mating force and contact reliability, the die must reproduce the same geometry throughout the entire production run.
Building on die plates machined to ±2 µm pitch accuracy, we design and build progressive dies for connector terminals and contacts, and can run mass production on our own presses.
What the industry requires, and how we respond
| Item | What the industry requires | Our response |
|---|---|---|
| Fine pitch | Narrower terminal pitch and fine blanking between adjacent terminals | 0.35 mm minimum pitch in production. ±2 µm pitch-accuracy plates keep station-to-station pitch error to a minimum. |
| Thin sheet & spring materials | Sheet around 0.1 mm and high-spring copper alloys | From 0.05 mm, with extensive experience below 0.1 mm. Phosphor bronze, beryllium copper, Corson alloy (Cu-Ni-Si), nickel silver and more. |
| Contact & mating dimensions | Minimal variation in bend angle, spring height and contact position | Plate accuracy that reproduces design clearances exactly, plus die designs with optimised relief and fits, keep dimensions stable throughout production. |
| High-speed production & die life | Long continuous runs at high SPM with long maintenance intervals | High-SPM die design, slug-pulling prevention controlled to 1/1000 mm, and rigid, concentric mounting of fine carbide punches for lines that keep running. |
| Surface quality on plated strip | No scratches or dents on plated surfaces | We run production on pre-plated and clad strip, and design strip feeding and guides to minimise contact with plated surfaces. |
| Delivery format | Continuous terminals on reels for automatic insertion and assembly | Reel-wound continuous terminals, as well as loose parts and trays. |

Why customers choose us
Die and production in one company
Die design, die building and mass production are all in-house. Our die designers see production issues first-hand and feed them into the next improvement.
Manufacturability input at the design stage
When quoting, we propose shape and tolerance changes, eliminating features that would not run stably before the die is built.
We own the die design data
Because we keep the design data in-house, we can handle maintenance, modifications and spare parts quickly.
Start with a single drawing.
We welcome early-stage inquiries, including parts other suppliers have turned down.
Our die designers will assess feasibility and get back to you.
