Southwest University of Science and Technology Visits – Deepening Industry-Research Integration and Jointly Promoting Innovation in Advanced Materials Heat Treatment Technology

I. Client Background

Client Name: Southwest University of Science and Technology

Visiting Unit: Representatives from the School of Materials and Chemistry and related research teams

Background: The School of Materials and Chemistry at Southwest University of Science and Technology has long focused on scientific research in key areas such as nuclear energy utilization materials, special energy materials, and optoelectronic functional materials. The university possesses deep research experience and a strong demand for experimental equipment in fields such as nuclear waste treatment and disposal materials, high-performance polymer films, powder metallurgy, and ceramic materials.

Visit Date: Early July 2025

Visiting Team: Representatives from relevant research teams of the School of Materials and Chemistry, including professors/associate professors and graduate students, totaling 7 people.

II. Visit Itinerary
Our technical team and international business department warmly received the visiting team from Southwest University of Science and Technology at our factory. After a brief welcome meeting in the conference room, our technical director comprehensively introduced the company's development history, product system, technological advantages, and latest R&D achievements in vacuum heat treatment, high-temperature sintering, and atmosphere control to the teachers. The visiting professors also shared the latest research progress and equipment needs of Southwest University of Science and Technology in areas such as the State Key Laboratory of Environmentally Friendly Energy Materials, nuclear waste treatment materials, high-performance thin film materials, and powder metallurgy.

Following this, the visiting team toured our company's production workshop, equipment assembly and debugging center, sheet metal processing workshop, and finished product display area. During the tour, the professors highly praised our 6S on-site management standards, lean production processes, and advanced processing equipment. They paid particular attention to the manufacturing details of several vacuum furnaces, tube furnaces, and bogie furnaces under assembly, including furnace body welding processes, vacuum system assembly processes, heating element layout, and temperature control system integration. They also frequently engaged in in-depth exchanges with our technical staff regarding quality control measures for key processes.

The afternoon's itinerary included live demonstrations of several pieces of equipment. Accompanied by our engineers, the visiting team observed the entire vacuuming and heating process of a heat-insulated vacuum furnace (working area 400×400×400mm), reviewed the independent temperature control effect of a multi-zone tube furnace, and observed the material tumbling and heating uniformity of a tilting rotary tube furnace under dynamic heating conditions. Both parties also conducted preliminary feasibility studies on specific process requirements related to the university's research projects, including high-temperature treatment of nuclear waste solidification materials, vacuum heat treatment of polymer films, and vacuum sintering of metal-based ceramic coatings. Our technical team provided preliminary process suggestions and equipment configuration schemes based on the characteristics of various materials.

III. Visit, Exchange, and In-depth Collaboration
Both parties conducted in-depth technical exchanges and project collaborations regarding the current research needs and future laboratory construction plans of the School of Materials Science and Engineering at Southwest University of Science and Technology.

Southwest University of Science and Technology's Relevant Research Directions and Equipment Needs: Southwest University of Science and Technology possesses the State Key Laboratory of Environmentally Friendly Energy Materials and the Provincial and Ministerial Collaborative Innovation Center for Nuclear Waste and Environmental Safety, conducting extensive research in the areas of nuclear waste treatment and disposal and radiation safety materials. The laboratory has independently developed a series of instruments and equipment, including a novel high-temperature ceramic rapid-fire equipment and a diamond thin-film CVD preparation system, achieving industrial-scale production of nuclear-grade extraction resins and the production and application of radiation protection gloves. In the research on radioactive waste vitrification, the university successfully developed a laboratory electric melting furnace for medium- and low-level radioactive waste vitrification, successfully producing and simulating nuclear waste vitrified products, achieving a breakthrough in my country's technology and process research in this field. These research efforts have created a continuous demand for vacuum sintering furnaces with high vacuum and high temperature uniformity, especially in optimizing the sintering process of nuclear waste vitrified materials.

During the exchange, our company highlighted the following equipment series:

Insulated Screen Vacuum Furnace Series: With an ultimate vacuum level of up to 6.67 × 10⁻³ Pa and a maximum operating temperature of up to 1400℃, it is suitable for sintering nuclear waste vitrified materials, vacuum sintering of hard alloys, and vacuum heat treatment of metallic materials. Its excellent temperature field uniformity and multi-segment programmable temperature control system can meet the high-precision control requirements of the nuclear industry for sintering processes.

Multi-zone tube furnace series: 2-5 independent heating zones, each with independent PID control, adjustable temperature gradients, and temperature control accuracy ±1℃. Particularly suitable for research applications such as functionally graded material synthesis, CVD thin film deposition, and continuous multi-step reactions within the same furnace tube.

Tilting rotary tube furnace series: Adjustable tilt angle 0-10°, adjustable rotation speed 0-15 rpm. Materials undergo a combined "tumbling + axial movement" motion, suitable for continuous drying, roasting, and heat treatment of powder materials. It has broad application prospects in mineral roasting, catalyst activation, and battery material processing.

Atmosphere muffle furnace series: Fully sealed furnace structure, capable of introducing various atmospheres such as Ar, N₂, O₂, and H₂/N₂ mixtures. Oxygen content can be controlled at the ppm level. Suitable for heat treatment of thin film materials sensitive to oxidizing/reducing atmospheres and sintering of battery materials.

IV. Customer Feedback and Future Cooperation

"This visit to your company was extremely fruitful. Our School of Materials Science and Chemistry at Southwest University of Science and Technology has extensive research work in areas such as nuclear waste treatment materials, high-performance thin film materials, powder metallurgy, and ceramic materials, and our needs for vacuum heat treatment equipment are very specific. Your technical team was able to provide targeted equipment configuration solutions and technical suggestions on-site based on our material characteristics and process requirements. This professionalism and responsiveness left a deep impression on us. Especially regarding the heat-insulated vacuum furnace and multi-zone tube furnace, the technical specifications and manufacturing processes of your products are highly compatible with our research needs. We look forward to establishing a long-term and stable cooperative relationship with your company to jointly promote the innovation and application of advanced materials heat treatment technologies."
