Frequently Asked Questions

Straightforward answers about our CNC milling, EDM, and stamping die services for heavy manufacturing.

What micrometric tolerances can your multiaxis CNC milling achieve?

Our machines hold geometric tolerances within ±5 microns on complex mold cavities, verified by in-process CMM inspection. This ensures the structural rigidity required for heavy-gauge stamping dies operating under cyclical press loads.

How does electrical discharge machining improve surface fidelity on hardened tool steels?

EDM removes material via controlled electrical sparks, producing a recast layer that can be polished to Ra 0.2 µm or better. This process avoids mechanical stress and thermal distortion, preserving the die’s dimensional stability through severe press cycles.

What is the typical lead time for a custom heavy-gauge stamping die?

Lead time depends on cavity complexity and steel grade. A single-station die typically ships in 6–8 weeks after design approval. We prioritize structural validation and heat treatment scheduling to avoid delays in your production timeline.

Do you offer design assistance for molds intended for high-cycle stamping?

Yes. Our engineers review your part geometry and press specifications to recommend draft angles, radii, and steel selection that maximize die life under repeated impact. We provide DFM feedback before any cutting begins.

What materials do you machine for heavy manufacturing molds?

We work with A2, D2, H13, S7 tool steels, as well as pre-hardened P20 and 420SS. For extreme wear resistance, we also machine carbide and powder-metal grades. Each material is paired with appropriate EDM or milling parameters to maintain tight tolerances.

How do you ensure repeatability across multiple die sets for the same part?

We use a combination of datum-based fixturing, thermal compensation routines, and statistical process control on critical features. Each cavity is documented with a full dimensional report, so replacement dies match the original within the specified tolerance band.

Core advantages

Why precision mold makers choose us

Every benefit is engineered for heavy-gauge stamping dies and severe press cycles.
01

Micrometric geometric tolerances

Our multiaxis CNC milling holds positions within ±5 µm, eliminating secondary finishing steps and reducing scrap rates on production runs.

Directly lowers per‑part cost in high‑volume stamping.
02

Superior surface fidelity for stamping

Electrical discharge machining delivers Ra 0.2 µm finishes on hardened tool steels, ensuring consistent material flow and minimal die wear during heavy‑gauge forming.

Extends die service life by up to 40% under cyclical loads.
03

Structural rigidity under severe press conditions

Each mold is designed with reinforced ribbing and premium tool steel grades, tested to withstand 500,000+ cycles without fatigue cracking or dimensional drift.

Reduces unplanned downtime and maintenance intervals.
04

Prolonged operational lifecycle

Advanced heat treatment and cryogenic processing increase surface hardness to 62 HRC, resisting abrasive wear from heavy‑gauge metal stamping.

Typical die life exceeds 2 million strokes before refurbishment.
05

Complex cavity geometries without compromise

5‑axis simultaneous milling and wire EDM enable deep ribs, undercuts, and tight internal radii that conventional machining cannot reach.

Enables one‑piece mold designs that eliminate weld lines and assembly errors.
06

Repeatable precision across production batches

In‑process CMM verification and closed‑loop feedback maintain Cpk ≥ 1.67 on critical features, ensuring every cavity matches the master CAD model.

Guarantees interchangeability of inserts and replacement parts.
