Tooling
Categories
The tooling types we design and build, with the advantages and trade-offs of each. Selecting the right category early is what keeps cost, lead time, and part quality in line — we will help you make that call before any design work begins.
TC-01
Class A & B Tooling
Tooling classified by expected production life. Class A is built for sustained high-volume production with hardened, ground details; Class B is built for lower volumes or bridge production where full Class A construction is not justified.
+ Advantages
- Tooling cost matched to the actual production volume required
- Class A gives predictable, long service life with scheduled maintenance intervals
- Class B lowers upfront investment for pilot or bridge runs
- Clear standard both sides can quote and inspect against
− Trade-Offs
- Class A carries a higher upfront cost and longer build lead time
- Class B has limited run life and will need rebuild or replacement sooner
- Underestimating volume at the start means paying twice
- Class definitions vary between shops and must be agreed in writing
TC-02
Stamping Dies
The general category covering press tooling that cuts and forms sheet metal. Ranges from single-station tools through fully automated multi-station sets, sized to the press and the part.
+ Advantages
- Very low cost per part once volume is reached
- High production rates with excellent part-to-part repeatability
- Wide material compatibility across steel, stainless, aluminum, and copper alloys
- Well-established process with predictable quality control methods
− Trade-Offs
- Significant upfront tooling investment before the first part
- Design changes after the tool is cut are expensive to implement
- Requires available press tonnage, bed size, and shut height
- Not economical for low volumes or frequently revised parts
TC-03
Blanking Dies
Cuts the flat developed shape out of strip or sheet stock in a single operation. Often the first station in a larger process or a standalone tool feeding downstream forming.
+ Advantages
- Simple construction, lower tooling cost, and shorter build time
- Fast cycle times with minimal setup
- Straightforward to maintain and resharpen
- Clean, consistent blank edge when clearance is set correctly
− Trade-Offs
- Skeleton and web material becomes scrap, affecting material utilization
- Performs one operation only — additional tools needed for forming or piercing
- Burr height and edge quality require ongoing clearance control
- Handling between operations adds labor if not integrated
TC-04
Bend & Form Dies
Produces bends, flanges, offsets, and formed features from a flat blank. Includes wipe, V-bend, U-bend, and restrike stations depending on the geometry and tolerance required.
+ Advantages
- Creates three-dimensional geometry without welding or secondary assembly
- Strong repeatability once springback is dialed in
- Can combine several bends in one press stroke
- Adds stiffness to the part without added material
− Trade-Offs
- Springback must be compensated in the tool and verified on first article
- Material lot variation shifts bend angle and may require tool tuning
- Tight inside radii risk cracking on harder or grain-sensitive material
- Restrike or coining stations may be needed to hold tight angular tolerance
TC-05
Riveted Assembly Tooling
Performs riveting and component joining inside the die, so parts leave the press already assembled rather than moving to a separate downstream station.
+ Advantages
- Eliminates a downstream assembly operation and its labor cost
- Joint quality is consistent because it is set by the tool, not the operator
- Reduces work-in-process inventory and handling damage
- Shortens total lead time from strip to finished assembly
− Trade-Offs
- More complex die design and a higher upfront tooling cost
- Component feed systems introduce additional failure points
- Troubleshooting is harder because the joint is formed inside the die
- A feed jam can stop the entire press rather than one station
TC-06
Cam Actuated Tooling
Uses cams and drivers to convert the vertical motion of the press ram into horizontal or angular action, allowing side piercing and side forming within a standard press.
+ Advantages
- Produces side-action features without a specialty press or secondary operation
- Allows undercuts and return flanges that vertical action cannot reach
- Keeps the whole part in one tool, protecting positional tolerance
- Compact — fits within an existing press envelope
− Trade-Offs
- More moving components means more wear surfaces to maintain
- Cam timing is critical and mis-timing can crash the tool
- Higher build cost and longer design time than straight vertical tooling
- Requires more skilled setup and die maintenance staff
TC-07
Rocker Arm Tooling
Uses pivoting rocker arms to transfer and redirect press force, delivering motion to locations a direct-acting punch cannot reach and providing mechanical advantage where it is needed.
+ Advantages
- Mechanical advantage delivers higher local force from the same press
- Reaches confined areas where a direct punch will not fit
- Enables multi-axis action within a single die set
- Motion ratio can be tuned by arm geometry during design
− Trade-Offs
- Pivot points wear over time and shift the working position
- Complex to build and requires precise initial setup
- Adds height and mass to the die, affecting shut height
- Maintenance requires understanding the linkage, not just the punch
TC-08
Progressive Dies
A multi-station tool where the strip advances through sequential stations — piercing, forming, extruding, tapping — with a finished part separating at the last station on every stroke.
+ Advantages
- Highest output of any die category — a finished part per stroke
- Lowest labor cost per part once the coil is running
- All features held in one tool, protecting feature-to-feature tolerance
- Complex parts completed without any secondary operations
− Trade-Offs
- Highest tooling cost and longest design and build lead time
- Strip layout errors are expensive to correct after the tool is cut
- Requires a coil feed line and press with adequate bed length
- A single station failure stops production of the entire part
TC-09
Swage Dies
Reshapes material by compression rather than cutting — reducing diameter, forming shoulders, or displacing material into a required profile without removing stock.
+ Advantages
- No material removed, so utilization is excellent
- Cold working increases hardness and strength in the formed area
- Produces a smooth, work-hardened surface finish
- Fast cycle time relative to machining the same feature
− Trade-Offs
- Requires high forming forces and adequate press tonnage
- Limited to geometry that material will flow into predictably
- Tool wear is significant on harder materials
- Work hardening may require an annealing step for further forming
TC-10
Draw & Redraw Dies
Forms a flat blank into a cup or shell using a punch, die ring, and blank holder, with redraw stations progressively reducing diameter and increasing depth.
+ Advantages
- Produces seamless hollow parts with no welded joint to fail
- Excellent strength and pressure integrity compared to fabricated equivalents
- Consistent wall geometry across high production volumes
- Eliminates welding, grinding, and leak-test operations
− Trade-Offs
- Wall thinning must be predicted and controlled through the draw sequence
- Blank holder pressure and lubrication require careful process control
- Wrinkling or tearing occurs if the draw ratio is too aggressive
- Material must be selected for formability, narrowing supplier options
TC-11
Deep Draw & Redraw
The extended case of drawing, where finished depth exceeds the part diameter. Requires multiple redraw stages and tightly controlled process conditions at every step.
+ Advantages
- Achieves depths not possible with single-stage drawing or fabrication
- Seamless construction with excellent strength-to-weight ratio
- Replaces multi-piece welded assemblies with one component
- Very low per-part cost at the volumes that justify the tooling
− Trade-Offs
- Highest risk of tearing, wrinkling, and earing of any forming process
- Interstage annealing is often required, adding cost and cycle time
- Demands tight control of lubrication, material grade, and grain direction
- Largest number of stations and the most development iterations to prove out
