After-Sales Services

Providing high-quality after-sales service ensures customers feel at ease when using and experiencing ONYX products. This includes spare parts replacement, product repairs, system support, software upgrades, and more.

ONYX has established a three-dimensional after-sales service system: "Technology + Supply Chain + Service." This seamlessly integrates technical support, supply chain management, and service assurance to provide customers with a unified and seamless after-sales service experience.

Technical Dimension：

Leverage digital technology to understand on-site conditions in advance, accurately match engineer skills with customer needs, and improve service efficiency.

Supply chain dimension：

Establish an efficient spare parts supply and logistics distribution network to ensure that the parts required for maintenance can be supplied in a timely manner.

Service Dimension：

Focus on the professional capabilities and service quality of the service team, as well as the standardization and regularization of service processes to ensure service quality.

After-Sales Service Process:

When customers encounter problems, they can communicate via WeChat, phone, or email. Leveraging intelligent technology connections, they receive accurate and rapid diagnosis and solutions.

At the same time, the supply chain ensures that required parts arrive promptly based on the bill of materials (BOM).

The service team efficiently completes online repairs or on-site maintenance work, allowing customers to experience convenient, efficient and professional services throughout the entire after-sales process.
