Die Design Services

The Problem We Solve

Bad Design = Expensive Rework

Most die problems aren't machining problems — they're design problems. A small oversight on the drawing turns into weeks of rework, thousands in wasted material, and missed production deadlines.

Without DFM Review

Die fails first tryout → 2–4 weeks rework → thousands in scrap → delayed production

With Our Design Process

Issues caught during design → fixed on screen → die runs right on first tryout

Design + Build In-House

Designers who've built dies — practical designs that actually work on the shop floor

Die Types We Design

Three Core Die Design Services

Progressive Dies
Compound Dies
Forming & Drawing Dies

Progressive Die Design

High-volume, high-speed stamping dies for continuous production. We design strip layouts, station sequences, and feed systems optimized for material utilization and die life.

Strip layout optimization — reduce scrap rate
Cam, lifter, and ejector system design
Material flow and springback analysis
Guide pillar and bushing selection for precision

Compound Die Design

Precision blanking and piercing dies for tight-tolerance parts with flat, clean edges. Ideal for medium-volume production where precision matters more than speed.

Blank and die opening clearance optimization
Piercing and shaving station layout
Stripper plate design for clean part ejection
Lower cost than progressive dies

Forming & Drawing Die Design

Deep drawing, bending, flanging, and forming dies for complex geometries. We optimize radii, blank holder pressure, and draw beads to control springback and splitting.

Blank holder and pressure pad design
Draw bead and radius optimization
Springback compensation design
Nitrogen gas spring selection for consistent pressure

How We Work

From Your Part Drawing to a Complete Die Design

Five clear steps that keep your project on track and catch issues before they become expensive problems.

1

Drawing Review

We review your CAD files, tolerances, and requirements — and flag any design concerns upfront.

2

DFM Analysis

We evaluate manufacturability and cost — and suggest design improvements early.

3

Strip Layout

We design the strip layout and station sequence — optimizing material utilization.

4

3D Die Design

Full 3D die design in SolidWorks — punches, dies, inserts, springs, guides.

5

Review & Approval

We share the 3D model and drawings for your review, revise, and lock the design.

Common Questions

Frequently Asked Questions

Quick answers to the questions we hear most often about our die design services.

How long does die design take?
Typical design time is 1–2 weeks for simple dies, and 3–4 weeks for complex progressive dies. We'll give you a clear timeline after reviewing your part drawing.
Can you help improve my part design?
Yes. Our DFM review flags manufacturability issues — sharp corners, tight radii, difficult features — and suggests design improvements that make the die more reliable and longer-lasting.
Do you also manufacture the dies you design?
Yes — we design and manufacture dies in-house at both our Dongguan and Nantong facilities. This means our designs are always practical and manufacturable, not just theoretical.
Are my drawings kept confidential?
Absolutely. We're happy to sign an NDA before any design work begins. Your part drawings and intellectual property are always protected.

Have a Part That Needs a Die Design?
