METAL STAMPING CAPABILITIES
We are a leading manufacturer of high-quality products. Our company has
Precision Stamping for Electronics & Power Systems
Zakobe specializes in high-precision metal stamping for electronics-scale components, with a core focus on contacts, bus bars, and conductive stamped parts where dimensional control, repeatability, and material integrity are critical.
Our processes, tooling, and inspection methods are engineered for repeat production, not experimentation.
Core Stamping Processes
Zakobe routinely performs the following stamping operations:
- Progressive stamping (core process)
- Blanking (core process)
- Piercing
- Forming
- Shallow draw
- Coining
- Fine blanking (tight-clearance, electronics-scale applications)
Core vs Occasional Processes
- Core: Progressive stamping, blanking
- Occasional: Forming, shallow draw, coining, fine blanking
Processes outside the core are evaluated based on part geometry, material behavior, and quality risk.
Press Equipment & Capacity
Zakobe operates seven gap-frame stamping presses, supporting a wide range of part sizes, materials, and production speeds.
Press Tonnage & Speed
- 5 ton — up to 280 SPM (2 presses)
- 33 ton — up to 600 SPM (2 presses)
- 45 ton — 60–180 SPM
- 60 ton — 60–175 SPM
- 250 ton — up to 35 SPM
Press selection is based on:
- Material type and thickness
- Feature density
- Required tolerance
- Tooling configuration
Material Thickness Capability
Published Routine Range
- 0.003" – 0.080"
This range reflects controlled, repeatable production for electronics and power-system components.
Expanded Capability
- Heavier-gauge applications up to 1.0" thickness are supported on the 250-ton press and addressed separately under large-format stamping programs.
Materials Processed
Zakobe regularly stamps:
- Copper and copper alloys
- Nickel alloys
- Carbon and alloy steels
- Pre-plated materials, including:
- Gold
- Tin
- Silver
- Nickel
- Gold
Materials Not Typically Processed
- Rubbers
- Hard plastics
- Specialty composite materials
Material selection is reviewed during quoting to ensure formability, tool life, and part consistency.
Tolerances & Precision
Typical production tolerances (process-dependent):
- Linear dimensions: ±0.003"
- Critical features: down to ±0.0005"
- Angular features: ±0.5°
Tighter tolerances are evaluated based on:
- Material behavior
- Tooling design
- Inspection strategy
Production Volumes & Scaling
Typical Lot Sizes
- 2,500 – 450,000 pieces
Capacity
- For a typical part, Zakobe can produce up to 750,000 pieces per week from a single tool on a single press under standard operating conditions.
Scaling strategies include:
- Multi-press tooling compatibility
- Redundant tooling builds for high-volume programs
Scaling Constraints
The primary scaling constraint is material supply, particularly at high volumes requiring mill-run material. These constraints are identified early during quoting.
Application Focus
Zakobe produces stamped components used in:
- Electrical contacts
- Bus bars
- Solder tabs
- Weld tabs
- Connectors and conductive interfaces
Core Specialization
Zakobe’s strongest and most repeatable applications are:
- Contacts
- Bus bars
These parts benefit most from our tooling approach, inspection methods, and material experience.
Process Selection Philosophy
There is no single correct way to stamp a part.
Process selection is determined by:
- Part geometry
- Material type and thickness
- Tolerance requirements
- Volume and lifecycle expectations
- Available equipment and tooling strategy
Zakobe evaluates each part for manufacturability and long-term stability rather than forcing designs into a preferred process.
