Purchasing a conveyor system is a significant capital investment — often ranging from $50,000 to $500,000+ depending on your production line requirements. Yet many manufacturers rush into contracts without properly vetting suppliers, leading to:
- ❌ Delivery delays that halt production for weeks
- ❌ Quality issues requiring expensive rework or replacement
- ❌ Poor after-sales support leaving you stranded when breakdowns occur
- ❌ Hidden costs that blow your budget by 30-50%
Pada Vitrans, we’ve seen countless examples of companies learning these lessons the hard way. That’s why we’ve created this comprehensive 15-point supplier evaluation checklist to help you make informed decisions.

- Overall satisfaction 12+ months post-installation
✅ Question 3: What is their annual production capacity?
What to look for: Capacity that matches your timeline needs
Why it matters: A supplier operating at 95%+ capacity may struggle with:
- Rush orders or timeline changes
- Quality consistency during peak periods
- Dedicated attention to your project
Good signs:
- Operating at 70-85% capacity (room for your project)
- Multiple production lines
- Scalable manufacturing partnerships
Section 2: Engineering & Technical Capability (Questions 4-7)
✅ Question 4: Do they have in-house engineering staff?
What to look for: Dedicated mechanical, electrical, and controls engineers
Why it matters: In-house engineering means:
- Faster design iterations

- Certifications (Professional Engineer licenses)
- CAD/CAM software capabilities
Red flag: All engineering outsourced to third-party firms
✅ Question 5: Can they provide detailed CAD drawings before production?
What to look for: 3D models, layout drawings, foundation plans
Deliverables should include:
- Overall layout with dimensions
- Component-level assembly drawings
- Electrical schematics
- Foundation and anchoring requirements
- Utility connection points (power, air, etc.)
Vitrans standard: We provide complete CAD packages within 5-7 business days of order confirmation, with unlimited revision rounds during approval.
✅ Question 6: What testing procedures do they follow?
What to look for: Documented FAT (Factory Acceptance Testing) protocols
Standard tests should include:
| Test Type | Duration | What to Verify |
|---|---|---|
| No-load run | 2-4 hours | Smooth operation, noise levels, alignment |
| Load test | 4-8 hours | Performance at rated capacity |
| Endurance test | 24-72 hours | Reliability under continuous operation |
| Safety check | 1-2 hours | Emergency stops, guards, interlocks |
Best practice: Request video documentation of FAT before shipment. Even better — attend in person for critical systems.
✅ Question 7: Do they offer custom engineering or only standard products?
What to look for: Flexibility to adapt to your specific needs
When customization matters:
- Unusual product sizes or weights
- Special environmental conditions (temperature, humidity, cleanliness)
- Integration with existing equipment
- Space constraints requiring non-standard layouts
Question to ask: “Can you show me an example of a custom solution you engineered for a client?”
Section 3: Manufacturing Quality (Questions 8-10)
✅ Question 8: What quality certifications do they hold?
Minimum certifications:
- ISO 9001 — Quality management system
- CE marking — European safety compliance (if exporting to EU)
- UL certification — US electrical safety (if exporting to USA)
Industry-specific certifications:
- USDA/FDA — Food grade applications
- Clean Room Class — Electronics/pharmaceutical
- Ex-rated — Explosive atmosphere environments
Verify: Ask for certificate numbers and verify directly with issuing bodies.
✅ Question 9: What materials do they use for critical components?
Key components to specify:
| Component | Standard Options | Premium Options |
|---|---|---|
| Frame | Mild steel (painted) | Stainless steel 304/316 |
| Belt | PVC, rubber | PU, silicone, modular plastic |
| Rollers | Carbon steel | Stainless, UHMW |
| Bearings | Standard | Sealed, food-grade |
| Motor | Generic brand | SEW, Nord, Siemens |
Red flag: Supplier cannot or will not specify material grades and component brands.
Vitrans transparency: We provide complete bill of materials (BOM) with brand names and specifications before production begins.
✅ Question 10: What is their defect rate and warranty policy?
What to look for:
- Defect rate below 2% (industry average is 3-5%)
- Minimum 12-month warranty on all components
- Clear warranty claim process
Warranty should cover:
- Manufacturing defects

- Modifications made by customer
Critical question: “What is your average response time for warranty claims?”
Section 4: Commercial Terms (Questions 11-13)
✅ Question 11: Is the pricing fixed or subject to change?
What to look for: Fixed-price contract with clear change order process
Common hidden costs:
- Engineering revision fees
- Expedited shipping charges
- Installation supervision (often quoted separately)
- Training costs
- Spare parts packages
Protect yourself: Contract should state:
“Total price is fixed unless customer requests changes to approved specifications. Any change orders must be documented in writing with cost impact before work proceeds.”
✅ Question 12: What are the payment terms?
Industry standard:
- 30% deposit with order
- 40% after design approval / before production
- 30% after FAT / before shipment
Red flags:
- 100% upfront payment demanded
- No retention amount for warranty period
- Unclear milestone definitions
Negotiation tip: For large projects (> $200K), negotiate 5-10% retention payable after successful commissioning.
