Frequently Asked Questions
1. What is the most important factor in supplier evaluation?
The most important factor is whether the supplier can reliably deliver equipment that meets your specific material, capacity, and quality requirements—verified by testing and references.
2. How do I evaluate a supplier’s technical capability?
Assess engineering team, design capability, material testing, and customization ability. Ask technical questions and request test reports.
3. How do I verify product quality?
Check component brands (SKF bearings, ABB motors), build quality, certifications (ISO, CE), and warranty terms. Request material testing.
4. What are the most important components to check?
Motor, bearings, gearbox, die, and controls are the most critical. Premium brands in these areas indicate quality.
5. How do I assess after-sales support?
Evaluate service team size and location, spare parts availability, warranty terms, and response time commitments. Contact references.
6. What are the biggest red flags?
No verifiable factory, vague component specifications, no references, no material testing, and short warranty are the biggest red flags.
7. How many suppliers should I evaluate?
Shortlist 3-5 suppliers for detailed evaluation. This provides competitive pricing while keeping the evaluation manageable.
8. How do I score suppliers?
Use a weighted scoring matrix: technical capability (25%), quality (25%), support (20%), manufacturing (15%), commercial (15%). Score each criterion 1-5 and calculate weighted total.
9. Should I always choose the lowest price?
No. The lowest price may mean lower quality, less support, or hidden costs. Consider total cost of ownership and supplier reliability.
10. What is the best way to verify a supplier?
Factory visits, reference calls, and material testing are the most effective verification methods.
