When purchasing heavy industrial equipment like roll forming machines, understanding the warranty and support terms is just as important as evaluating performance specifications. A warranty protects your investment, while after-sales support ensures that unexpected issues don’t undermine production or increase lifecycle costs.
This page explains what buyers can reasonably expect from Shijiazhuang Yingyee Machinery Co., Ltd. in terms of warranty coverage, duration, types of support offered, common limitations, and practical steps to protect themselves when contracting internationally.
Yingyee generally offers a 12-month warranty period from the time of delivery or dispatch for its roll forming and metal processing machines. This applies across product categories including purlin lines, stud and track formers, storage rack machines, and similar equipment.
Core coverage: Most machines are backed by a 12-month warranty.
Warranty start date: Usually begins from the delivery date (documented through shipping or Bill of Lading).
Some listings also describe this as “warranty of core components.”
During the warranty period, a typical supplier warranty for roll forming machines will include:
Failures due to manufacturing flaws
Premature wear not caused by misuse
Breakdowns of mechanical or control components
For Yingyee systems, this generally includes the core machine structure, forming stands, control systems, and other major assemblies.
Repair of failed parts at no additional machine cost
Replacement of defective components
Sometimes support for adjusting or realigning installed machines
This is standard practice in machinery supply — but specifics should be confirmed in writing.
Most industrial OEM warranties exclude:
Consumables (e.g., shear blades, tooling wear parts)
Damage from misuse or improper operation
Installation errors if not performed by approved technicians
Unauthorized modifications after installation
Normal wear and tear over time
For example, coatings on roll surfaces, hydraulic seals, or punch tooling are typically not covered as part of routine wear.
Note: While this is standard across manufacturers, specific limitations should be clearly drafted in your contract.
In addition to warranty coverage, Yingyee typically communicates after-sales support that includes:
Online guidance through:
fault diagnosis
parameter adjustment
basic troubleshooting
This support is often offered via email, video call, or messaging channels.
Some listings mention engineers available for overseas service — typically at extra charge for travel, accommodation, and daily rates.
Buyers usually receive:
electrical diagrams
control wiring schematics
user manuals
troubleshooting guides
These documents are critical for local maintenance and should be delivered at time of sale — not assumed.
Strong warranty enforcement depends on how risks are allocated in the contract. Common requirements include:
✔ Machine maintained according to specified schedules
✔ Operators trained on correct procedures
✔ Faults reported promptly with photographic/video evidence
✔ Logs maintained for machine usage, hours, and issues
Without documented maintenance records, some suppliers limit warranty responsibility.
International equipment warranties often have constraints:
Travel for technicians to foreign sites is usually not covered unless explicitly negotiated.
Spare parts shipped from China can have:
long lead times
customs clearance delays
additional freight costs
Plan to maintain some spare parts locally.
Contracts should specify:
where disputes are adjudicated
who pays for warranty-related shipping
what qualifies as “defect” vs operator error
These make warranty enforcement smoother.
To protect warranty rights, include in your purchase contract:
Exact length (e.g., 12 months from delivery/commissioning)
Clear list of parts covered
Repair response expectations (e.g., remote response times)
Onsite support terms if negotiated
Out-of-warranty support cost structure
Operation manual (English or relevant language)
Electrical schematics
PLC program copy
List of spare parts with reference numbers
These deliverables are often overlooked but essential for resolving issues.
In many international machinery deals, buyers negotiate that the warranty start date is tied to:
✔ Successful Factory Acceptance Testing (FAT)
and/or
✔ On-site Commissioning Acceptance
This ensures the warranty truly begins when the machine is installed and running to expectations, not merely at shipment. Explicit language helps avoid claims lapsing before commissioning.
Public product descriptions consistently list “12 months warranty” for equipment such as storage rack roll forming machines and stud/track lines. They also often mention engineers being available to service machinery overseas — although the details of travel/per diem are usually separate charges.
If your acceptances include specific dimensional and speed tolerances, incorporate these into warranty obligations.
Take photos/video of machine condition at commissioning. This helps avoid disputes over whether an issue was present at start.
Common parts to stock include:
bearings
proximity switches
hydraulic seals
encoder wheels
fuses and relays
This reduces downtime and puts you in a stronger negotiating position.
Yingyee machines generally come with a 12-month manufacturer warranty covering defects and core system failures from the time of dispatch or delivery. Buyers should expect:
basic remote support during warranty
the possibility of engineers available overseas (often at extra cost)
exclusions for wear items and misuse
documentation and acceptance criteria defined upfront
To maximize protection:
negotiate warranty start tied to FAT or commissioning
detail covered parts and response times
plan for spare parts and local maintenance
Clear contract language combined with realistic expectations ensures your warranty delivers real value — reducing long-term risk and protecting your investment in roll forming equipment.
