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 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.
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.
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.
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.
Drawing Review
We review your CAD files, tolerances, and requirements — and flag any design concerns upfront.
DFM Analysis
We evaluate manufacturability and cost — and suggest design improvements early.
Strip Layout
We design the strip layout and station sequence — optimizing material utilization.
3D Die Design
Full 3D die design in SolidWorks — punches, dies, inserts, springs, guides.
Review & Approval
We share the 3D model and drawings for your review, revise, and lock the design.
