Manufacturing Capabilities

Stamping Die
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.

01
Progressive Dies

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 Stations
02
Transfer Dies

Separate 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 Geometries
03
Compound Dies

Blanking and piercing in a single simultaneous stroke. Produces flat parts with exceptional flatness and positional accuracy — washers, discs, precision blanks.

Single-Stroke Multi-Op
04
≤5μm BURR
Fine-Blanking Dies

Triple-action tooling with V-ring and counter punch for shear-cut burr-free edges across full material thickness. Eliminates secondary operations.

Burr ≤ 5μm
05
Deep Drawing Dies

Multi-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 ≤ 2.5:1

Supported Operations

Stamping 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.

Blanking

Shearing the outer part profile from sheet metal with controlled punch-die clearance for clean cut edges.

Piercing

Punching holes, slots, or cutouts with the slug discarded. The pierced sheet is the finished workpiece.

Forming

3D shape generation by plastic deformation without material removal — combining bends, offsets, and contours in one die.

Bending

Angle forming with V-dies, U-dies, or wipe tools. Spring-back compensation built into every die for consistent angle accuracy.

Deep Drawing

Controlled material flow forming cups, shells, and enclosures. Blank holder force and punch radius precisely engineered.

Embossing

Raised or recessed logos, ribs, and identification marks without material removal — thickness redistribution creates the geometry.

Coining

High-pressure full-surface contact die squeezing — zero spring-back. Produces coin-flat surfaces and sharp corners for contacts and connectors.

Tapping

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%.

Engineering &
Manufacturing Workflow

A structured 10-step process from drawing to certified sample delivery — engineering checkpoints at every stage.

10 STEPS DFM MATERIAL CAD/CAE CNC EDM HEAT TX FITTING TRYOUT PPAP DELIVERY
01
Drawing / DFM Analysis

Customer 2D/3D drawings reviewed for manufacturability — radii, draft angles, wall thickness, and feature feasibility validated before quoting.

02
Material Selection

Die steel grade selected by application: SKD11, DC53, Cr12MoV, PM-HSS, or tungsten carbide inserts based on volume, material stamped, and tolerance spec.

03
CAD / CAE Die Design

3D die design in SolidWorks/CATIA with FEA forming simulation for spring-back prediction, station layout, and BOM generation for CNC programming.

04
CNC Machining

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.

05
Wire EDM & Sinker EDM

Wire EDM for punch profiles and die openings to ±0.002mm. Sinker EDM for blind cavities, engraving, and features unreachable by conventional machining.

06
Heat Treatment

Vacuum hardening to HRC 58–62 for SKD11. Cryogenic treatment plus double tempering stabilises dimensions and eliminates residual stress before grinding.

07
Precision Fitting

Surface grinding, lapping, and hand-fitting to design clearances. Every punch-die interface fitted and confirmed under CMM before assembly.

08
Tryout & Optimisation

Press tryout on production material. Parts measured on CMM; clearances, spring-back, and pitch adjusted iteratively until dimensional conformance is achieved.

09
FAI / PPAP Sample Approval

Full FAI dimensional report with CMM printout, material certs, and Cpk data. PPAP Level 3 including control plan and PFMEA available on request.
