PRECISION DIES

Precision Dies

What Are Precision Dies?

Precision dies are custom stamping tools that cut, bend and form sheet metal into specific part geometries. Each die is developed around a customer's part drawing, material and production volume, then built to run reliably in a stamping press.

You typically need a precision die when a part must hold tight geometry across high volumes. That includes connectors, terminals and battery parts. You also need it when burr control and dimensional repeatability matter downstream.

✓Custom to your drawing

✓±0.005 mm repeatability

✓Design to tryout, in-house

▤Typical Capabilities

Tolerance	±0.005 mm (can reach ±0.002 mm)
Tool steel hardness	58–62 HRC
Surface finish	Ra ≤ 0.2 μm
Life cycle	Up to 10,000,000 strokes
Die size	Up to 600 × 2000 mm
Stamping thickness	0.05–6 mm (material dependent)
Stamping materials	Stainless steel, copper alloys, aluminum, special alloys

Values are typical ranges; actual figures depend on part design, material and volume.

One Roof, One Chain

Design, strip layout, machining and assembly in one facility — reducing outsourcing risk and lead time.

Heat Treatment & Tryout

Die components are heat-treated and the assembled die is tested on a press before shipment.

Process Consistency

Grinding, EDM and CNC run under the same quality system, so each component follows one standard.

Quality & Inspection

Every die is checked against the drawing with CMM and optical measurement before shipment. Inspection runs in a controlled-environment lab, so measurements are stable and repeatable.

✓ ISO 9001:2015 certified quality system across design, machining and inspection.

✓ Sample part inspection — first articles checked on CMM and projector against the customer drawing.

✓ Controlled-environment lab — dimensional checks under stable temperature conditions.

What Affects Die Design?

Four factors drive how a precision die is laid out and built.

Part Geometry

Holes, slots, bends and formed features determine how many stations the die needs and the order of operations.

Material & Thickness

Different metals and gauges change cutting behavior, springback and required punch-to-die clearance.

Production Volume

Expected run length influences tool steel choice and how wear-prone components are designed.

Critical Dimensions

Features holding tight tolerance get dedicated stations and inspection points, not post-stamping luck.

These factors are why a die approach starts with your drawing, material and volume.

We Review & Discuss

Our engineers check formability and strip layout, then come back with questions or a die approach.

Precision Dies — Common Questions

What information should I provide to start a die project?+

At minimum: a 2D drawing or 3D model, material and thickness, and expected volume. Critical dimensions and plating requirements help us evaluate the die layout more accurately.

Can you build a die from my own drawings?+

Yes. Most precision dies are built from customer-supplied drawings or CAD files. Send the part drawing and the engineering team will review formability and tooling approach.

Can you supply both the die and the die set / mould base?+

Yes. We build precision dies, die sets and non-standard mould bases, so the die and its structural support can come from one supplier. See our tooling die sets for the standard range.
