1. Bench pickup check
Start with representative parts, including the worst expected surface condition. Check pickup contact, peel risk, air gap, and any stacked-part behavior before approving the gripper concept.

- Static and dynamic holding requirements
Holding Force and Pole Layout Review Buyer Decision Framework
Treat holding force and pole layout review as a complete handling decision, not a stand-alone magnet purchase. The right choice depends on whether the workpiece can be held magnetically, whether the robot motion keeps enough margin, whether the part releases cleanly, and whether the installation scope is clear enough for quotation.
Buyer fit: For teams that need a magnetic gripper sized around real parts instead of catalog assumptions. Before comparing price, align the practical constraints below so the quote reflects the real automation cell instead of a generic catalog condition.
| Decision Area | Buyer Question | Practical Evidence |
|---|---|---|
| Workpiece fit | Can the magnetic poles contact enough real surface area under production conditions? | Send workpiece material, dimensions, thickness, and weight plus photos or drawings of the pickup face. |
| Motion margin | Will the gripper hold through acceleration, rotation, off center pickup, and stop conditions? | Review force margin because the right margin depends on workpiece, motion, orientation, and risk level. |
| Release behavior | Can the part release within the placement tolerance without residual magnetism, double pickup, or stack disturbance? | Define sample acceptance criteria around force margin and record the release test result before batch release. |
| Interface scope | Are the flange, adapter, cable, connector, controller, and documentation assumptions included in the same RFQ? | Confirm material and magnetic permeability and list any custom mounting or control requirements before PO release. |
Validation Plan Before program release
2. Robot-path check
Test the planned orientation, acceleration, tool center, cable route, and stop assumptions. A static lift is not enough when the cell includes fast motion or rotated handling.
3. Release and repeat run
Measure release timing, residual magnetism, placement tolerance, and repeatability across a small run. Use the result to freeze pole layout, interface, and quality-control notes.
Procurement Notes and Boundaries
The most common sourcing mistake is treating holding force as a fixed catalog value. In practice, holding force is estimated from catalog assumptions instead of the real workpiece. Review the workpiece material, contact area, air gap, and surface condition before final selection. Another common issue is that release behavior changes after coating, oil, burrs, or stack height variation. Validate release timing and residual magnetism with representative samples before batch production.
For a quote that can move from engineering review to procurement, include the workpiece file set, automation interface, cycle target, release requirement, quantity, destination, and any custom packaging or documentation needs. If those values are not final, mark them as assumptions so the quotation can separate confirmed scope from validation-dependent scope.
- Use Contact / RFQ when drawings, photos, robot model, and quantity are ready for review.
- Review sample validation and quality control if the application includes coating, oil, burrs, stack variation, or release precision risk.
Program Evaluation Matrix
| Program Metric | Typical Range | Procurement Value |
|---|---|---|
| Force margin | Defined by application review and sample tests | The right margin depends on workpiece, motion, orientation, and risk level. |
RFQ Preparation Checklist
- Workpiece material, dimensions, thickness, and weight
- Surface condition, coating, oil, burrs, holes, and stacking state
- Target holding force, safety factor, release behavior, and cycle rate
- Robot, cobot, or automation interface with available power and signals
- Quantity, project stage, destination, and customization requirements
Risk and Mitigation
- Holding force is estimated from catalog assumptions instead of the real workpiece.: Review the workpiece material, contact area, air gap, and surface condition before final selection.
- Release behavior changes after coating, oil, burrs, or stack height variation.: Validate release timing and residual magnetism with representative samples before batch production.
- Robot payload and moment limits are checked without the full EOAT mass.: Confirm gripper mass, adapter plate, cables, workpiece weight, and motion profile together.

Buyer FAQ
Can you quote from photos and drawings?
Yes. Photos, drawings, material notes, weight, target cycle, and robot model are enough for an initial review. Sample validation is recommended before final release.
Do you support OEM customization?
Yes. We can review pole layout, mounting plates, cable and connector needs, controller interface, packaging, and batch production requirements.
Can one magnetic gripper fit every metal part?
No. Magnetic gripping depends on material, contact area, air gap, thickness, surface condition, and motion. We size and validate around the actual workpiece.
