Offer customer service acceptance 24 hours a day. Users have several options for submitting the service declaration to the Customer Service Response Center, including phone, fax, mail, and email.

We have a strong R&D team,and we can develop and produce products according to the drawings or samples the customers offered.

We often visit users to check on project implementation and after-sales maintenance, listen to their feedback, and assess the project as it actually stands. This information serves as a key foundation for our evaluation of the company's support staff.

A thorough technical consulting contact letter will be given to the user following the execution of the project contract. Throughout the whole warranty (maintenance) period, customers can contact us at any time by phone, fax, letter, email, or another flexible communication method.
