"Can you do this accuracy, at this thickness?" Here is the answer up front.
This page summarises what design and purchasing engineers most often check early in a project: sheet thickness, materials, accuracy, equipment capacity and data formats. If your requirement is not listed, or goes beyond the stated range, please ask. Our designers will assess feasibility and get back to you.
High-Accuracy Plate Machining
Our Mitsubishi Electric MP2400 ultra-high-precision wire EDM runs in a dedicated climate-controlled room. Die plates and stripper plates, which determine how reproducibly a die performs, are machined with stable sub-micron accuracy.
| Pitch accuracy (proven) | ±0.002 mm (±2 µm) Achieved under climate control |
|---|---|
| Surface roughness (proven) | Ra 0.04–0.2 µm |
| Work size | 600 × 400 mm Maximum machining envelope |
| Plate thickness | Up to 60 mm |
| Materials | SKD11 (D2), SKH51 (M2), powder HSS, tungsten carbide, etc. |
| Minimum corner radius | R 0.075 mm Depends on wire diameter |
| Minimum slit width | 0.15 mm With ø0.1 mm wire |
| Machining environment | Dedicated climate-controlled room Reduces thermal displacement from temperature change |
| Typical applications | Die plates, stripper plates and punch plates for progressive dies; individual die components |
Precision Stamping Die Design & Fabrication
Centred on progressive dies, we design and build dies for fine-pitch, thin-sheet and micro-geometry parts such as electronic components and connector terminals. Manufacturability consulting from the design stage delivers both long die life and stable volume production.
| Die type | Progressive dies |
|---|---|
| Part sheet thickness | 0.05–3.0 mm Extensive experience below 0.1 mm |
| Minimum pitch | 0.35 mm Extensive experience with fine-pitch terminals |
| Minimum punch diameter | ø0.5 mm Carbide micro punches |
| Punch / die materials | Tungsten carbide, powder HSS, SKD11 (D2), etc. |
| Die size | Up to 1000 × 400 mm Subject to plate machining envelope |
| Design system | 2D/3D integrated CAD/CAM (EXCESS HYBRID) |
| Typical products | Connector terminals and contacts, lead frames, shield cases, spring parts, precision chassis components |
| Features | Designed for high SPM, slug-pulling prevention, optimised relief and fit, high-rigidity / high-concentricity assembly, design data retained in-house |
Precision Metal Stamping
Fourteen presses, centred on Kyori precision high-speed automatic presses. We draw out the full potential of our own dies and support your volume production with lines that keep running.
| Presses | 11 precision high-speed automatic presses (Kyori and others), 3 servo / Hi-Flex presses (Aida) |
|---|---|
| Press capacity | 30–150 t |
| Sheet thickness | 0.05–3.0 mm |
| Strip width | Up to 100 mm |
| Materials | Phosphor bronze, beryllium copper, Corson alloy (Cu-Ni-Si), brass, nickel silver, stainless steel, nickel alloys, copper, aluminium, etc. Pre-plated and clad materials also handled |
| Minimum lot size | Prototype and small lots welcome — please ask |
| Delivery format | Reel-wound (continuous terminals), loose parts, trays |
| Quality control | 100% or sampling inspection according to part characteristics; real-time production data collection from tablets on every press (MD SYSTEM for PD) |
| Certifications | ISO 9001:2015 / ISO 14001:2015 |
Inspection & Measurement
Measurement is performed on a Tokyo Seimitsu coordinate measuring machine and Keyence image dimension measuring systems and digital microscope. First articles are delivered with an inspection report.
| Coordinate measuring machine | Tokyo Seimitsu XYZAX AXCEL 9/6/6 |
|---|---|
| Image dimension measuring systems | Keyence LM-1000 / IM-6000 / IM-7000 |
| Digital microscope | Keyence VHX-700F |
| Measuring room | Climate-controlled |
| Documentation | First-article inspection report, measurement data Customer-specified formats accommodated on request |
Data Formats & Working With Us

Telling us the following speeds up our reply
You do not need all of it. Share whatever you know.
- Part drawing or data (2D or 3D; a rough sketch is fine)
- Material and thickness (plating, if any, and preferred supplier if specified)
- Critical dimensions and tolerances (features that need the tightest control)
- Expected quantity (monthly / annual volume, or prototype quantity)
- Target delivery (approximate dates for first articles and production start)
- Scope of engagement (die plus production, die only, production only, components only)
- Preferred delivery format (reel, loose, tray, etc.)
- Whether an NDA is required (please send your template if you have one)
See Manufacturing Process for what happens after you place an order, and FAQ for answers to common questions.

Requests that go one step beyond the listed range — a thinner sheet, a finer pitch —
are exactly where our strengths come into play.
