Technology and equipment

With technology as a shield, we can ensure the quality and delivery of fasteners.

We have always maintained a rigorous approach to productquality management, committed to meeting externalrequirements and expectations. Detailed inspections arecarried out from initial proofing to series production. To meetthe industry quality standards, CNRl will do a series of testson automotive fasteners, including mechanical andchemical tests, such as hardness, metallographic, tensilestrength, yield, neutral salt spray test, friction coefficient, etc.to ensure the quality and durability of all fasteners. Thecustomized products will be assembled and tested on actua!objects after production to ensure that the productsdelivered to customers meet the promise of exceeding theirexpectations! Consequently,our professional productinspection report is convenient for customers to check all theinformation regarding the Qc of the product, offering themprofessional insight on the product quality. The packaging ofthe relevant accessories contains a description that providesessential installation information for different fasteners.Testing with the direct-reading spectrometer, platingthickness gauge, tensile testing machine, salt spray testchamber, Lowe's hardness tester, metallographicmicroscope,etc,, helps conform to relevant industrystandards as well.

Six Things to Consider Before Automation

  • 1.Material and process innovation

    2025-05-28

    Automotive requirements for fastener materials are gradually increasing, both to meet the needs of lightweight, but also to ensure sufficient strength and durability. Therefore, it is necessary to choose high-strength and lightweight materials, such as aluminum alloy, magnesium alloy, titanium alloy and carbon fiber composite materials.

    And the innovation of fastener manufacturing process is crucial to improve production efficiency and product quality. For example, Rayon continues to use advanced cold extrusion technology, heat treatment technology and surface treatment technology, which can significantly improve the mechanical properties and corrosion resistance of fasteners.【detailed】

  • 2.Design and standardization

    2025-05-28

    The design of fasteners needs to take into account the special needs of electric vehicles, such as the fixing of battery packs, the connection of motors and drive systems. By optimizing the design of fasteners, it is possible to improve their connection efficiency and reliability, while reducing weight and cost.

    Promoting the standardization of fasteners helps to reduce production costs, improve production efficiency, and promote interoperability between different suppliers. Therefore, when developing fastener standards, the special needs of electric vehicles need to be fully considered.

  • 3.Automation and intelligent production

    2025-05-28

    In order to improve production efficiency and reduce costs, fastener manufacturing needs to achieve automated production. Through the introduction of advanced automation equipment and robotics, fasteners can be quickly and accurately processed and assembled. This is also the direction of CNRL's development

    Using technologies such as the Internet of Things, big data and artificial intelligence, intelligent management of the fastener production process can be achieved. This includes monitoring production status in real time, predicting equipment failures, optimizing production plans, and more. These are some of the smart technologies that CNRL continues to incorporate and adopt in its fastening systems and solutions.

  • 4.Supply Chain Management Optimization

    2025-05-28

    The development of the automotive market has put forward higher requirements for the supply chain management of fastener manufacturers. Manufacturers need to optimize supply chain management and reduce costs to improve the market competitiveness of products.

    Establish long-term and stable cooperative relations with raw material suppliers to ensure the quality and supply stability of raw materials; On the other hand, the cost is reduced by optimizing the production process and improving the production efficiency. In addition, we also introduce advanced management methods to further enhance the efficiency and effectiveness of supply chain management

  • 5.Quality control and inspection

    2025-05-28

    The quality of fasteners directly affects the safety and reliability of automobiles. Therefore, CNRL has established a strict quality control system and conducts multiple rounds of inspection of raw materials, semi-finished products and finished products to ensure that they meet quality standards.

    The use of advanced testing technology, such as non-destructive testing, mechanical properties testing, etc., can more accurately evaluate the quality and performance of fasteners.

  • 6.Environmental protection and sustainable development

    2025-05-28

    Choosing environmentally friendly and recyclable materials for fastener manufacturing helps reduce environmental pollution and waste of resources.

    In the process of fastener manufacturing and electric vehicle production, energy saving and emission reduction measures need to be taken to reduce energy consumption and carbon emissions.

    With the increasing attention of the world to environmental protection and sustainable development, Ruili auto fastener manufacturers are also actively promoting green production and achieving sustainable development. We offer custom fastening systems specifically designed for clean energy applications.
