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.

Automotive Automation Buyer Decision Framework
Treat automotive automation 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 automotive suppliers, integrators, and equipment builders handling ferromagnetic components. 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 part number, material grade, surface treatment (e-coat, phosphate, zinc), 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 validation scope because automotive projects usually need clear acceptance evidence before production release. |
| Release behavior | Can the part release within the placement tolerance without residual magnetism, double pickup, or stack disturbance? | Define sample acceptance criteria around validation scope 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 part variation and surface treatment and list any custom mounting or control requirements before PO release. |
Validation Plan Before application validation
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, surface treatment changes (e.g., new coating supplier) affect magnetic holding without warning. Include magnetic response validation in the engineering change process and re-test with new-coating samples before line release. Another common issue is that automotive quality documentation (ppap, fmea, control plan) is requested after the gripper is already in production. Agree on quality documentation scope and format during the RFQ phase, not after the first batch ships.
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.
Application Evaluation Matrix
| Evaluation Metric | Typical Range | Buyer Relevance |
|---|---|---|
| Validation scope | Defined by sample parts and internal acceptance criteria | Automotive projects usually need clear acceptance evidence before production release. |
RFQ Preparation Checklist
- Part number, material grade, surface treatment (e-coat, phosphate, zinc), and weight
- Line takt time, station sequence, and transfer distance between stations
- Robot or transfer system model, payload, and controller generation
- Quality documentation requirements: PPAP level, Cpk, FMEA, and control plan expectations
- Annual volume, program duration, and engineering change notification process
Risk and Mitigation
- Surface treatment changes (e.g., new coating supplier) affect magnetic holding without warning.: Include magnetic response validation in the engineering change process and re-test with new-coating samples before line release.
- Automotive quality documentation (PPAP, FMEA, control plan) is requested after the gripper is already in production.: Agree on quality documentation scope and format during the RFQ phase, not after the first batch ships.
- Part variation across multiple stamping or forming tools changes the magnetic contact area.: Test representative parts from each tool cavity or forming station to confirm the gripper works across the full part population.

Buyer FAQ
Can you support PPAP documentation for automotive gripper projects?
We can provide dimensional reports, material certificates, and process documentation to support your PPAP submission. Define the required PPAP level in the RFQ so we can plan accordingly.
How do you handle engineering changes on automotive programs?
We follow a formal change-control process: the buyer submits the change request, we review impact on the magnetic circuit and tooling, and re-validate with updated samples before releasing the revised design.
What automotive part types suit magnetic gripping?
Steel brackets, stamped panels, formed parts, blanks, and machined components with ferromagnetic properties. Non-magnetic alloys (aluminum body panels, stainless exhaust parts) require different gripping methods.
