How Do I Inspect a Roll Forming Machine Before Shipping?
Before shipment, the machine should be powered and tested under real production conditions.
The Core Principle
A proper pre-shipment inspection must verify:
- 1️⃣ Mechanical integrity
- 2️⃣ Electrical functionality
- 3️⃣ Hydraulic performance
- 4️⃣ Profile accuracy
- 5️⃣ Safety compliance
- 6️⃣ Documentation completeness
- 7️⃣ Packing readiness
Never rely on photos alone.
Step 1️⃣ Conduct a Full Factory Acceptance Test (FAT)
Before shipment, the machine should be powered and tested under real production conditions.
Verify:
- ✔ Profile produced matches approved drawing
- ✔ Dimensions within tolerance
- ✔ Surface finish acceptable
- ✔ Punch locations accurate
- ✔ Cut length accurate
- ✔ Speed performance confirmed
- ✔ Emergency stops functional
Request production samples.
Document everything.
Step 2️⃣ Verify Mechanical Alignment
Inspect:
- ✔ Shaft straightness
- ✔ Roll gap consistency
- ✔ Stand alignment
- ✔ Gearbox mounting
- ✔ Chain tension
- ✔ Bearing preload
Check for:
-
Frame twist
-
Uneven stand spacing
-
Visible vibration during test run
Alignment issues worsen during shipping.
Step 3️⃣ Inspect Roll Tooling Condition
Examine:
- ✔ Roll surface finish
- ✔ No scratches or pits
- ✔ No burrs on edges
- ✔ Proper radii
- ✔ Clean chrome or hardened finish
Tooling damage before shipment becomes your problem after arrival.
Step 4️⃣ Test Hydraulic System
Verify:
- ✔ Pump pressure
- ✔ Stable pressure reading
- ✔ No leaks
- ✔ Smooth cylinder movement
- ✔ Shear operation accuracy
- ✔ Punch return speed
Inspect hoses and fittings.
Hydraulic instability causes commissioning delays later.
Step 5️⃣ Verify Electrical & PLC System
Confirm:
- ✔ Correct voltage specification
- ✔ Control panel labeling
- ✔ PLC program backup provided
- ✔ Encoder calibration
- ✔ Sensor response
- ✔ No fault codes
- ✔ Emergency stop response
Request a copy of PLC program on USB.
Step 6️⃣ Confirm Power Specification Matches Destination
Verify:
- ✔ Voltage (380V, 415V, 480V etc.)
- ✔ Frequency (50Hz or 60Hz)
- ✔ Transformer requirements
- ✔ Motor ratings
Incorrect frequency setup can cause motor overheating later.
Step 7️⃣ Confirm Included Accessories
Cross-check contract against delivery:
- ✔ Decoiler capacity
- ✔ Coil car (if included)
- ✔ Stacker
- ✔ Punch tooling
- ✔ Spare parts kit
- ✔ Shear blade sets
- ✔ Lubrication system
Do not assume optional accessories are included unless documented.
Step 8️⃣ Inspect Structural Frame
Check:
- ✔ Weld quality
- ✔ No visible cracks
- ✔ Anchor bolt holes aligned
- ✔ Frame paint condition
- ✔ No structural bending
Frame integrity determines long-term accuracy.
Step 9️⃣ Check Safety Compliance
If required:
- ✔ CE marking
- ✔ UKCA
- ✔ UL (if applicable)
- ✔ Guarding installed
- ✔ Interlocks functional
- ✔ Warning labels present
Compliance issues can cause customs delays.
Step 🔟 Review Documentation Package
Request:
- ✔ Operation manual
- ✔ Electrical drawings
- ✔ Hydraulic schematic
- ✔ Spare parts list
- ✔ Maintenance schedule
- ✔ Warranty terms
- ✔ FAT report
Missing documentation delays installation.
Step 11️⃣ Photograph Everything
Before packing:
- ✔ Entire machine
- ✔ Control panel interior
- ✔ Tooling
- ✔ Serial plates
- ✔ Accessories
- ✔ Spare parts
Photos protect insurance claims.
Step 12️⃣ Supervise Packing
Ensure:
- ✔ Moving parts locked
- ✔ Shear secured
- ✔ Punch head tied down
- ✔ Electrical cabinet sealed
- ✔ Moisture barrier applied
- ✔ Desiccant packs included
- ✔ ISPM-15 certified wooden crates used
- ✔ Container bracing installed
Poor packing causes alignment damage.
Step 13️⃣ Confirm Shipping Documents
Verify:
- ✔ Commercial invoice
- ✔ HS code
- ✔ Certificate of origin
- ✔ Insurance certificate
- ✔ Packing list
- ✔ Bill of lading draft
Errors here cause customs delays.
Most Common Pre-Shipment Mistakes
- 1️⃣ Skipping full load test
- 2️⃣ Not verifying voltage/frequency
- 3️⃣ Not measuring produced profile
- 4️⃣ Ignoring hydraulic leaks
- 5️⃣ Not checking accessories list
- 6️⃣ No photo documentation
- 7️⃣ No PLC backup provided
These mistakes cause post-arrival disputes.
If You Cannot Visit Factory
Options:
- ✔ Hire third-party inspection company
- ✔ Request live video FAT
- ✔ Require signed inspection checklist
- ✔ Request sample shipment in advance
Never skip independent verification on high-value machines.
Final Expert Insight
A proper pre-shipment inspection should:
- ✔ Verify machine performance
- ✔ Confirm dimensional accuracy
- ✔ Confirm electrical compatibility
- ✔ Confirm all accessories
- ✔ Validate documentation
- ✔ Ensure correct packing
- ✔ Protect warranty & insurance rights
Once the machine leaves the factory, your leverage is reduced.
Inspection before shipment is risk control.
