The Materials Science Laboratory of Xi'an Jiaotong University (hereinafter referred to as the client) has purchased a tungsten heating furnace from our company for research on heat treatment of new materials. After using the device for a period of time, the customer encountered a device abnormality during an experiment, which affected the experimental process. The customer immediately contacted our company to request technical support and after-sales service.

It was determined that the previous inappropriate parameters caused excessive temperature overshoot after starting the heating process, resulting in a rapid increase in temperature from the cold furnace within a short period of time. The vacuum degree could not be maintained below 10pa, causing the molecular pump to shut down for protection. After adjusting the parameter data, the temperature control system was fully calibrated and the overall performance of the equipment was tested to restore it to normal operation. The engineer also thoroughly cleaned and maintained the equipment to ensure its long-term stable operation.

  After the equipment repair, our company's Mr. Li had in-depth communication with laboratory personnel, providing detailed explanations and demonstrations on the operation process, maintenance points, and common troubleshooting methods of the electric furnace, in order to help customers better manage and use the equipment. At the same time, based on the usage of the equipment and the laboratory environment, Mr. Li proposed targeted equipment maintenance suggestions and preventive maintenance plans to reduce the possibility of future failures.

In this follow-up visit to our clients, our company provided comprehensive services such as rapid response, professional diagnosis, efficient maintenance, operation guidance, and preventive maintenance to ensure the normal progress of laboratory research work. The high praise from the customer not only reflects their recognition of our after-sales service, but also further consolidates the partnership between the two parties. Our company will continue to uphold the principle of customer first, provide timely, professional, and thoughtful after-sales service to customers, ensure the stable operation of scientific research equipment, and assist in the smooth progress of scientific research.
