Warranty structure is one of the most misunderstood — and most critical — parts of purchasing a new roll forming system.
Buyers often assume:
“12 months warranty” means full machine protection
All components are covered equally
Downtime costs are reimbursed
Wear parts are included
Travel is included
Software support is unlimited
In reality, warranty structure is a contractual risk allocation document. It defines:
What is covered
What is excluded
What remedies are available
Who pays for labor and travel
How claims are validated
How long coverage lasts
For engineered OEMs like Samco, warranty terms typically align with industrial equipment standards — but buyers must understand how these terms function in real production environments.
This page explains warranty structure clearly and independently so buyers can evaluate risk properly before signing.
A typical industrial roll forming machine warranty covers:
Structural fabrication defects
Component failure due to faulty assembly
Defective electrical panel build
Incorrect wiring
Improper installation of OEM-supplied components
If a machine cannot perform the specified scope due to design miscalculation, this may fall under warranty — but only within the defined project scope.
Major components (gearboxes, motors, drives, PLC hardware) are typically covered under either:
OEM’s direct warranty
Component manufacturer warranty
Warranty does not generally cover performance outside the agreed material or production scope.
In industrial roll forming:
12 months from commissioning is common
Sometimes 12 months from shipment (less favorable to buyer)
Extended warranty options may be available at additional cost
Important distinction:
Warranty from shipment reduces effective coverage window if commissioning is delayed
Warranty from commissioning protects startup phase better
Buyers should clarify the start date definition.
Warranty scope often differs between:
Covered for:
Structural defects
Assembly errors
Premature component failure
Excluded:
Wear parts
Misalignment from improper installation
Damage from overload
Covered for:
Panel build defects
Faulty wiring
PLC hardware defects
Excluded:
Software changes by third parties
Voltage fluctuation damage
Improper grounding
Customer modifications
Electrical issues often depend on site power quality.
Wear parts are almost always excluded from warranty.
Common wear parts include:
Roll tooling
Punch tooling
Bearings
Belts
Seals
Hydraulic hoses
Filters
Cutting blades
Wear depends on:
Material quality
Production volume
Maintenance practices
Warranty does not typically cover normal wear.
Tooling is often misunderstood.
Tooling warranty may cover:
Manufacturing defects
Hardness or heat treatment errors
Dimensional machining errors
It does not cover:
Surface wear
Damage from incorrect material
Improper setup
Misalignment caused by base leveling errors
Tooling performance depends heavily on setup and maintenance discipline.
Some projects include performance criteria such as:
Dimensional tolerance at production speed
Hole position accuracy
Maximum scrap rate
If defined in contract and validated at FAT, these may form part of performance warranty.
However:
If production changes after acceptance (new material, higher yield steel, speed increase), warranty may not apply.
Performance must be tied to documented FAT results.
Hydraulic systems are covered for:
Pump defects
Valve manufacturing faults
Assembly errors
Excluded items often include:
Seal wear
Oil contamination
Overheating from improper maintenance
Improper pressure adjustments
Hydraulic failure due to oil contamination is typically not warranty.
Drive systems and gearboxes are usually covered against:
Manufacturing defects
Assembly misalignment
Excluded:
Over-torque from improper material
Shock damage from punch overload
Misalignment caused by improper anchoring
Improper foundation installation often voids mechanical warranty claims.
Software logic is generally covered if:
It does not function according to documented scope
It contains OEM programming errors
Excluded:
Modifications made by customer
Unauthorized parameter changes
Integration with third-party devices not in original scope
Remote support access policies also influence warranty support speed.
This is often overlooked.
Warranty may include:
Replacement parts
Remote support
But may exclude:
Travel expenses
On-site labor
Accommodation costs
Some OEMs cover travel within the first 30–90 days, but not full warranty period.
Buyers must confirm:
Who pays for travel during warranty claims?
Typical claim process:
Buyer identifies issue
Documentation of fault provided
Remote diagnostics performed
OEM determines whether defect qualifies
Replacement part shipped or technician scheduled
Clear documentation speeds claims.
Lack of maintenance logs weakens claims.
Common warranty void triggers include:
Operating outside material specification
Exceeding rated thickness
Modifying machine without OEM approval
Ignoring maintenance schedule
Electrical supply instability
Safety bypasses
Improper installation or leveling
Warranty is contingent on proper use.
Commissioning quality directly affects warranty validity.
If:
Machine not leveled properly
Anchors not torqued correctly
Encoder not calibrated
Power unstable
Mechanical stress increases, and warranty disputes become complex.
Commissioning documentation protects both buyer and OEM.
Some buyers negotiate:
18–24 month extended warranty
Spare parts kits included
Preventative maintenance support
Remote monitoring services
Extended warranties increase cost but reduce risk during early production ramp.
Factory Acceptance Testing defines baseline performance.
If FAT verifies:
Dimensional accuracy
Speed capability
Punch alignment
Then warranty generally covers deviations from those validated conditions.
If FAT is vague, warranty disputes become subjective.
Define FAT clearly to protect warranty claims.
For new systems, warranty structure is standard.
For refurbished or used systems:
Limited warranty (30–90 days typical)
Parts-only coverage
No performance guarantee
Buyers must distinguish new vs refurbished coverage.
Before signing a contract, confirm:
☑ Warranty duration start date
☑ Coverage scope (mechanical, electrical, software)
☑ Wear part exclusions
☑ Travel & labor inclusion/exclusion
☑ Performance criteria definition
☑ FAT validation linkage
☑ Spare parts support timeline
☑ Conditions that void warranty
☑ Extended warranty options
☑ Claim response time expectation
This checklist prevents future disputes.
Warranty is not insurance against all production issues.
It protects against:
OEM design defects
Manufacturing errors
Component defects
It does not protect against:
Poor maintenance
Material variability
Improper installation
Operator error
Understanding this distinction prevents unrealistic expectations.
Warranty structure in Samco roll forming systems reflects standard industrial risk allocation: protection against manufacturing and design defects within defined operating scope.
Buyers who:
Define scope clearly
Validate performance at FAT
Document commissioning
Maintain equipment properly
Clarify travel and labor terms
Understand exclusions
…protect themselves from disputes and production downtime.
Warranty evaluation is not about negotiating longer coverage alone — it is about ensuring alignment between:
Scope
Engineering
Acceptance
Maintenance
Risk responsibility
Done properly, warranty becomes a clear framework rather than a future argument.
