Our service promise is not a slogan, a concept or an advertisement, our service promise is serious. To this end, we have built a large, systematic and standardized service guarantee system to ensure that each link is implemented in place and finely processed.

We have assembled and specialized a large team of installation engineers


EPC stands for project general contracting, also known as "turnkey solution". This mode is often used in the field of engineering construction.

Generally speaking, the projects that adopt the EPC project general contracting mode are generally projects with large investment scale, long construction period, relatively complex technology, and many uncertain factors. Therefore, this also puts forward high requirements on the overall strength of the contractor.

As part of a turnkey solution with expertise and experience in general contracting of projects, we provide customers with:

  • Free site survey
  • Material inspection
  • Market analysis
  • Global scheme design
  • Return on investment analysis
  • Site Planning
  • Foundation construction guidance
  • Equipment installation guide
  • Production line management training
  • Delivery inspection test machine
  • Original parts supply
  • Project transformation

Investing in leading technology and expert training will help you maximize efficiency so you can take your company to the next level. You’ll benefit from a smoother and safer process, fewer production errors, and a higher return on investment.

We provide comprehensive and systematic training for the technical staff of each user to better serve the needs of customers' projects. After the technicians have finished their studies, they will return to the project during the operation period. TongLi Industry will provide follow-up technical support services, and the training instructors will follow up the project use effects in the later stage to ensure the stable operation of the customer projects.


Training is provided to all employees who are in contact with our equipment. We aim for all employees to gain a full understanding of our equipment and its capabilities to unleash its full potential.

Training service scope:

  • System training
  • Installation skills training
  • Equipment structure and principle training
  • Fault judgment and troubleshooting training
  • Equipment maintenance training
  • Equipment operation training
  • Core component introduction training
  • Accessory installation training
  • Field operation training
  • Production process training
  • Material processing technology training

Based on many years of market experience and project experience, we provide professional production line transformation services for customers who already have production lines, provide high-performance equipment to replace old equipment, greatly increase the output of old production lines, and allow customers to spend less investment. Obtain huge benefits.


With the help of equipment upgrade services, you will be able to improve old production lines to make them more efficient and avoid technical problems.


  • Replace aging equipment that has actually reached or is approaching the end of its useful life cycle
  • Implement easy available engineering features and solutions to expand equipment capabilities and efficiency
  • Refurbish, repair, and replace subassemblies to improve equipment operation and safety
  • Production transformation, to produce more high-value products according to market demand, and improve the profitability of the entire production line.

We provide customers with comprehensive installation training services, including site leveling, foundation drawing inspection, construction progress and team planning, guidance for the entire process of equipment installation, and production line test machines to ensure that the production line runs well until the customer is satisfied. TongLi's many years of on-site management experience makes production line management no longer a problem.


With the help of equipment upgrade services, TongLi provides commissioning services to customers who purchase equipment. Training can also be added as a service package.


  • Assure that equipment is designed, installed, tested, operated, and maintained according to installation and operational requirements of a new project
  • Assure that the refurbished equipment is assembled, installed, tested, operated, and maintained according to installation and operational requirements after revamping
  • Provide technical services, operator training and assistance in equipment installation and setup

TongLi provides you with detailed equipment maintenance knowledge and various maintenance techniques, so that you can become an "engineer" without leaving home. You can also sign up for system training, or call our after-sales engineers to help you.


Through this service, we strive to eliminate any inconvenience that TongLi machinery may cause and ensure the normal operation of the equipment.


  • Maximize the use of machinery and parts without jeopardizing machine reliability
  • Accurately predict and schedule maintenance work
  • Improve the efficient use of maintenance resources by scheduling corrective maintenance when a potential failure is observed rather than performing unscheduled maintenance upon component failure
  • Reduce the frequency of unexpected equipment failures
  • Maintain equipment in good operating condition
