Stamping Tooling Manufacturer
Precision Stamping Die & Tooling Manufacturer
In-House Die Making · Wire EDM · D2 / SKD11 Tool Steel
Progressive dies, compound dies, fine blanking tooling and transfer dies — engineered, machined and validated in our 6,000 m² toolroom. Tolerance to ±0.005 mm on critical punch and die components.
Why In-House Tooling Matters
When a stamping manufacturer owns its die room, the feedback loop between part quality and tooling corrections shrinks from weeks to hours. We design, build, trial, and maintain all tooling under one roof — no external die shops, no communication gaps.
Faster Design Changes
Engineering change orders are fed directly to die makers on the shop floor. Minor punch repositioning or size adjustment typically takes 1–2 days, not 2–3 weeks at an external tool shop.
Tighter Tolerances
In-house EDM and precision grinding lets us match punch-to-die clearances to within 0.003 mm — critical for micro-parts, fine blanking, and tight-tolerance connectors.
Lower Total Cost
No third-party tooling markup. Shared overhead between high-volume and short run programs means you benefit from economies of scale even on small-batch tooling investments.
Preventive Maintenance
Die maintenance schedules tied directly to press counter data. Punch sharpening, guide replacement, and die polishing done proactively — not reactively after a quality escape.
Die Types We Manufacture
Progressive Dies
Multi-station dies for high-speed strip feeding. Up to 20 stations — blanking, piercing, bending, forming, trimming — in one die set. Most economical for volumes above 50,000 pcs.
- Strip width: 10 – 300 mm
- Press tonnage: 30 – 400T
- Speed: up to 600 SPM
Compound Dies
Blanking and piercing in a single stroke. Produces flat parts with superior flatness and concentricity. Ideal for washers, gaskets, shims, and simple brackets.
- Flatness: ≤ 0.05 mm
- Concentricity: ≤ 0.03 mm
- Cut edge perpendicularity: ≤ 0.02 mm
Transfer Dies
Parts transferred between stations by mechanical fingers. Suited for larger parts (over 100 mm) or deep-draw components that cannot be produced in strip-fed progressive format.
- Part size: 50 – 500 mm
- 3–6 station transfers typical
- Press: 160 – 800T
Fine Blanking Dies
Triple-action tooling with V-ring stinger to produce burr-free, perpendicular, shear-smooth cut edges. Surface roughness Ra ≤ 0.8 µm without secondary finishing.
- Material: steel to 8 mm thick
- Tolerance: ±0.01 mm
- Edge perpendicularity: 100% burnish zone
Deep Draw Dies
Single or multi-draw tooling for cups, cans, housings, and shells. Draw ratios up to 2.5:1. Blank holder force and draw ring geometry engineered to prevent wrinkling and thinning.
- Draw diameter: 5 – 250 mm
- Wall thickness variation: < 10%
- Redraw stages: up to 5
Micro & Specialty Dies
Custom dies for connectors, contacts, micro-springs, and lead frames. Punch diameters from 0.1 mm, clearance from 0.003 mm. Built in climate-controlled environment.
- Min punch diameter: 0.1 mm
- Min clearance: 0.003 mm
- Material: carbide inserts available

Tooling Materials & Steel Grades
D2 Tool Steel (Cr12MoV)
HRC 60–62 after heat treatment. Standard choice for progressive die punches and inserts. Excellent wear resistance for steel and stainless strip stamping. Life: 1–3M strokes.
SKD11 (Equivalent to D2+)
Higher vanadium content than standard D2. Superior toughness for high-speed operations (300+ SPM). Our default punch material for fine-blanking and micro-dies.
Tungsten Carbide
For ultra-long life applications (>5M strokes) and abrasive materials (silicon steel, hard stainless). Used as punch tips or full punch bodies in micro-die applications.
P20 / NAK80 (Pre-hardened)
HRC 30–40. Used for die shoes, cam blocks, and soft tooling applications where lower hardness with good machinability is preferred. Faster to machine for bridge tooling.
Tooling Design Process
Every die goes through a structured design and validation process to ensure it performs to specification from the first stroke.
DFM Analysis
Part geometry reviewed for stampability. Minimum feature sizes, bend radii, grain direction, and spring-back validated before die design begins.
Strip Layout Design
Material utilisation optimised (target >75%). Station sequence planned for force balance and pilot hole accuracy. Carrier width and bridge dimensions set.
3D Die Design (CAD)
Full 3D model in SolidWorks/AutoCAD. Interference checks, punch clearance simulation, cam and lifter motion analysis, and assembly drawing issued for review.
Machining & EDM
CNC roughing → heat treatment → wire EDM finishing → surface grinding. Each component inspected on CMM before assembly into die set.
Trial & T1 Samples
Die trialled on press at target speed. T1 samples measured against drawing. Adjustments made in die room, not on press floor. T1 report issued within 48h.
Customer Approval & Production
Customer signs off on T1 report. Die locked to approved setup parameters. Tooling card created for preventive maintenance tracking throughout production life.
Tooling Ownership & Storage
We believe tooling should protect your business, not lock you in. Our tooling policy is transparent and customer-friendly.
You Own the Tooling
100% customer ownership after tooling payment is settled. Full die drawing and BOM provided on request. No IP restrictions on your part geometry.
Free Storage 2 Years
Dies stored in a climate-controlled toolroom at no charge for 2 years. Extended storage available at nominal cost. Dies tagged and tracked in our ERP system.
Maintenance Included
Routine punch sharpening and die cleaning included in production cost. Major repairs quoted separately with customer approval before work begins.
Die Shipment Available
If you choose to move production, we will package and ship your die to your designated location. Export documentation and customs support provided.
Frequently Asked Questions
How long does tooling take to build?
Standard progressive die: 14–21 days from approved drawing. Complex fine blanking or deep-draw tooling: 25–35 days. Expedite programs (additional cost) can compress simple dies to 7–10 days.
What is the cost of a typical progressive die?
Simple 3–5 station progressive die in D2 steel: $2,000–$6,000. Complex 10–15 station die with in-die forming: $8,000–$25,000. Fine blanking or carbide-insert dies: $15,000–$50,000. All pricing includes T1 samples and dimensional report.
Can you replicate a die from an existing part sample?
Yes. We can reverse-engineer existing parts using CMM scanning and produce a matching die. Tolerance to the reverse-engineered dimension is typically ±0.02 mm. A formal drawing is preferred for traceability.
Do you manufacture tooling for external stamping companies?
We primarily build tooling for our own stamping production. However, for high-value tooling projects (above $20,000), we do accept external die manufacturing orders. Contact us to discuss your requirements.
What happens to the tooling when a product is discontinued?
We will notify you before storage expiry. You can extend storage, ship the die, or authorize us to scrap it. All decisions require written customer authorisation. We never scrap a die without customer approval.
