Capabilities
From single-station blanking tools to 24-stage progressive dies — our in-house capabilities span the full spectrum of precision stamping tooling, backed by CAE simulation at every stage.
Multi-station dies performing sequential operations on a continuous strip. Up to 24 stations — ideal for high-volume terminals, connectors, and brackets.
Up to 24 StationsSeparate blanks transferred station-to-station by servo fingers. For larger complex parts with deep draw or multi-directional forming that can't run on a strip.
Complex GeometriesBlanking and piercing in a single simultaneous stroke. Produces flat parts with exceptional flatness and positional accuracy — washers, discs, precision blanks.
Single-Stroke Multi-OpTriple-action tooling with V-ring and counter punch for shear-cut burr-free edges across full material thickness. Eliminates secondary operations.
Burr ≤ 5μmMulti-stage reduction dies for cups, shells, and 3D enclosures. Draw ratios up to 2.5:1 achieved with optimised blank holder, punch radius, and clearance geometry.
Draw Ratio ≤ 2.5:1Up to 1,200 SPM engineering with tungsten carbide inserts, DLC coatings, and precision guide systems for connector terminals, micro-contacts, and lead frames.
Up to 1200 SPMStamping Processes
We integrate all core metal forming operations within a single progressive or transfer die — combining multiple processes for reduced cycle time and tighter process control.
Shearing the outer part profile from sheet metal with controlled punch-die clearance for clean cut edges.
Punching holes, slots, or cutouts with the slug discarded. The pierced sheet is the finished workpiece.
3D shape generation by plastic deformation without material removal — combining bends, offsets, and contours in one die.
Angle forming with V-dies, U-dies, or wipe tools. Spring-back compensation built into every die for consistent angle accuracy.
Controlled material flow forming cups, shells, and enclosures. Blank holder force and punch radius precisely engineered.
Raised or recessed logos, ribs, and identification marks without material removal — thickness redistribution creates the geometry.
High-pressure full-surface contact die squeezing — zero spring-back. Produces coin-flat surfaces and sharp corners for contacts and connectors.
In-die internal thread forming within the progressive stroke, eliminating secondary operations on high-speed production lines.
All processes above are integrated within our progressive and transfer die designs. We run CAE forming simulation for spring-back prediction and optimisation before cutting steel — reducing first-tryout risk and development time by up to 40%.

Manufacturing Workflow
A structured 10-step process from drawing to certified sample delivery — engineering checkpoints at every stage.
Customer 2D/3D drawings reviewed for manufacturability — radii, draft angles, wall thickness, and feature feasibility validated before quoting.
Die steel grade selected by application: SKD11, DC53, Cr12MoV, PM-HSS, or tungsten carbide inserts based on volume, material stamped, and tolerance spec.
3D die design in SolidWorks/CATIA with FEA forming simulation for spring-back prediction, station layout, and BOM generation for CNC programming.
High-speed 4-axis CNC milling at ±0.005mm positioning. Die blocks, punch holders, and backing plates machined from pre-hardened or annealed tool steel.
Wire EDM for punch profiles and die openings to ±0.002mm. Sinker EDM for blind cavities, engraving, and features unreachable by conventional machining.
Vacuum hardening to HRC 58–62 for SKD11. Cryogenic treatment plus double tempering stabilises dimensions and eliminates residual stress before grinding.
Surface grinding, lapping, and hand-fitting to design clearances. Every punch-die interface fitted and confirmed under CMM before assembly.
Press tryout on production material. Parts measured on CMM; clearances, spring-back, and pitch adjusted iteratively until dimensional conformance is achieved.
Full FAI dimensional report with CMM printout, material certs, and Cpk data. PPAP Level 3 including control plan and PFMEA available on request.
Die sets cleaned, oiled, and packed in custom foam with moisture-proof barrier. Exported via DHL/FedEx/sea freight with full documentation and die maintenance manual.
Quality Assurance
Every stamping die undergoes a documented multi-stage inspection protocol. We measure, validate, and certify before any die leaves our facility.
Mill certificates verified against spec. Hardness spot-tested; die steel blocks measured before entering production.
100% Material TraceabilityEach punch-die clearance measured by CMM and feeler gauge. Clearance uniformity ≤ 0.002mm variation around perimeter confirmed.
±0.002mm Clearance Control50,000–100,000-stroke durability run on production press with dimensional sampling at 10k intervals for stability verification.
50,000 – 100,000 Stroke TrialFull FAI report with CMM printout for every critical dimension, including balloon reference, measured value, and conformance status.
PPAP Level 3 AvailableMaterials & Steel Grades
Correct material selection is fundamental to die life and part quality. We stock and specify the right grade for every application and volume requirement.

Standard production capability. Tighter tolerances achievable on request via additional EDM and lapping operations.
Surface Finishes
The right surface treatment extends die life, reduces friction, prevents galling, and directly improves the quality and consistency of stamped parts.
Ra ≤ 0.05μm on punch faces and die cavities. Reduces ejection force, prevents material adhesion, improves surface quality of drawn parts.
Die life +30%Gas or plasma nitriding creates a hardened layer (HV 900–1100) to 0.1–0.3mm depth — dramatically improves wear resistance without dimensional change.
Surface hardness +60%Diamond-Like Carbon 1–4μm thick. Friction coefficient as low as 0.05 — ideal for stainless steel and copper stamping where adhesive wear is the primary failure mode.
Friction coeff. −70%PVD titanium nitride (gold) and titanium carbonitride (grey) 2–5μm, HV 2300+. Suitable for high-volume applications with abrasive materials.
Wear life ×3–5Electrodeposited hard chrome 5–50μm, HRC 70+ surface. Applied to punch shanks, guide posts, and wear surfaces for corrosion and abrasion resistance.
Corrosion resistance +90%Precision surface grinding Ra 0.2–0.8μm and diamond lapping Ra ≤ 0.05μm. Ensures accuracy and flatness of mating die components after heat treatment.
Flatness ≤ 0.002mmChemical conversion coating providing corrosion inhibition with near-zero dimensional change (<1μm). Used for die bodies, retainer plates, and backing plates.
