Request documentation of testing procedures, failure rate statistics, and after-sales service protocols.

Customization and Engineering Support

Small producers often differentiate themselves through flexibility. Evaluate whether the supplier offers custom payloads, reach configurations, end-effector integration, or proprietary software interfaces. A dedicated engineering team can significantly reduce integration time and improve ROI.

Scalability and Delivery Performance

Assess not only current capacity but also the supplier’s ability to scale with your business. Metrics such as on-time delivery rate, lead times, and reorder frequency provide insight into operational stability. For instance, Jiangsu Jitri Intelligent Manufacturing Technology Institute Co., Ltd. reports a perfect 100% on-time delivery rate, signaling exceptional logistical execution despite moderate reorder rates.

Communication and After-Sales Service

Rapid response times (<7 hours) and multilingual support are critical for global operations. Prioritize suppliers who offer remote diagnostics, firmware updates, training programs, and spare parts availability. These services minimize downtime and extend equipment lifespan.
