Stamping Dies & Tooling — Custom Die Design and Fabrication
Our full-service in-house tool and die shop provides complete metal stamping die design, fabrication, maintenance, and repair services. From initial concept through production-ready tooling, our experienced die makers build high-performance stamping dies that deliver precise, repeatable results across millions of press cycles. By controlling the entire tooling process in-house, we ensure faster lead times, tighter quality control, and lower total tooling costs.
Our tooling capabilities support all our stamping processes — progressive die stamping, deep draw, sheet metal stamping, and compound die operations. Whether you need a new production die, a prototype soft tool, or maintenance on an existing die, our team has the expertise and equipment to deliver.
Types of Stamping Dies We Build
- Progressive dies — multi-station dies with up to 30+ stations for high-speed production. Each station performs a sequential operation (blanking, piercing, bending, forming) producing a finished part with every press cycle.
- Compound dies — perform blanking and piercing simultaneously in a single stroke, producing parts with superior flatness and concentricity between features.
- Transfer dies — individual die stations with mechanical part transfer for larger and deeper formed parts that cannot be carried on a progressive strip.
- Deep draw dies — single and multi-stage drawing tooling for cups, enclosures, housings, and cylindrical components.
- Line dies — individual stamping dies operated in a tandem press line for large body panels and structural parts.
- Secondary operation dies — trimming, piercing, restrike, and forming dies for operations on pre-formed parts.
- Prototype / soft tooling — quick-turnaround tooling for prototype quantities and design validation before committing to production tooling.
Die Design Engineering
Our engineering team uses industry-leading tools for die design and validation:
- SolidWorks 3D modeling — full 3D die design with interference checking and assembly verification
- Stamping simulation — forming analysis to predict material flow, thinning, springback, and wrinkle risk before any steel is cut
- Strip layout optimization — maximizing material utilization to reduce per-part material cost
- FEA analysis — stress analysis of die components to ensure adequate strength and longevity
Every die design begins with a thorough review of your part geometry, material properties, tolerance requirements, and production volume. We optimize the die design for part quality, die life, cycle time, and maintainability — minimizing your total cost of ownership over the life of the tooling.
Die Shop Equipment
- Wire EDM machines — ±0.0001 inch accuracy for die sections and punch profiles
- CNC machining centers — 3-axis and 4-axis for die blocks, punch holders, and die shoes
- precision metal stamping surface grinders — flatness and parallelism to ±0.0002 inches
- Jig grinding — for precise hole locations and profile grinding
- Die spotting press — for die tryout, blue spotting, and adjustment
- Heat treating — in-house and outsourced hardening to optimize die component life
Custom Metal Stamping Dies
Every stamping die we build is custom-engineered for your specific part geometry, material, production volume, and tolerance requirements. We design dies to maximize tool life (typically 500,000 to 5,000,000+ hits depending on material and complexity), minimize scrap, and optimize cycle time for the lowest total cost per part.
Die Maintenance and Repair
Proper die maintenance extends tool life and maintains part quality. We provide:
- Preventive maintenance programs with scheduled die inspection and sharpening
- Emergency die repair for broken punches, worn die sections, and damaged components
- Die modification for engineering changes and part revisions
- Die refurbishment for worn tooling that needs reconditioning
- Maintenance on dies not originally built by us
