Seemingly humble drill tail screws, with the core advantages of self-drilling, efficient assembly, stable and durable, and diversified scenes, cover the vast majority of thin metal fasteners from construction engineering to new energy infrastructure, from transportation manufacturing to home appliance production. It not only simplifies the construction process, improves the production and construction efficiency, reduces the project cost, but also through the continuous upgrading of materials and processes, ADAPTS to all kinds of complex and harsh working conditions, and ensures the structural safety and long-term stability of all kinds of projects and equipment.
Under the industrial development trend of assembly, lightweight and efficiency, the application scenarios of drilling screws continue to expand.
Iii. Transportation and rail transit industry: key parts for lightweight assembly
The transportation field has strict requirements for precision, strength and fatigue resistance of accessories. With the characteristics of efficient assembly, anti-vibration and high adaptability, drilling screws are widely used in automobile manufacturing, rail transit, outdoor transportation facilities and other scenes.
In automobile manufacturing, the bulk assembly of thin metal parts, such as body sheet metal, interior metal support, air conditioning shell, and car door fittings, are all using drilling screws. The feature of no pre-punching greatly simplifies the assembly process of the automobile production line, and improves the overall assembly efficiency by more than 40%. At the same time, the optimized drilling screw can pass 2 million times of vibration fatigue tests, which is perfectly suitable for high-frequency vibration conditions in vehicle driving, and is not easy to loosen and break, ensuring the stability of body structure and interior accessories.
In the field of rail transit, the lightweight plate, equipment cabinet and line support of high-speed railway and subway carriages are fixed, as well as the outdoor protective facilities and signal equipment shell assembly. With the advantages of small, precise, firm fastening and strong weather resistance, the drilling screw is suitable for the narrow installation space of the carriages and the complex outdoor working conditions. In the installation of outdoor traffic facilities such as highway guardrails, traffic signs, street lights metal bases, it can quickly complete the fixation of plates and supports, convenient construction, rustproof and durable, suitable for all kinds of outdoor environments.
Iv. Household appliances and industrial manufacturing industry: the efficiency of batch production is just needed
Household appliances and general industrial equipment are mostly thin metal plates and aluminum alloy profiles, and mass production has extremely high requirements for assembly efficiency, appearance cleanliness and cost control. The wonderful use of drilling screws is reflected incisively and vividly in this scene.
The assembly of the shell sheet metal, internal metal support and heat dissipation components of household appliances such as refrigerators, air conditioners, washing machines and disinfection cabinets basically uses the drilling screw in the whole process. Traditional screw assembly needs to punch holes in advance and lock the position, which is time-consuming and laborious, and is prone to hole position deviation, which affects the appearance and accuracy of products. The drilling screw can directly penetrate the thin plate of household appliances, and complete the tightening at one time. The hole position is accurate, and the surface is smooth and unbulging, which perfectly meets the requirements of fine production of household appliances, and greatly reduces the labor and time costs of mass production.
At the same time, the assembly of industrial electrical cabinets, storage shelves, logistics boxes, refrigeration equipment, and communication cabinets also rely on a large number of drilling screws. Aiming at the use scenarios of electronic equipment and precision cabinet, small precision drill tail screws can realize lightweight fasteners, avoid plate deformation, take into account the stability of product structure and appearance texture, and adapt to the production needs of various light industries and precision manufacturing.
V. Outdoor decoration and municipal engineering: the adaptation artifact of complex scenes
Outdoor decoration, municipal facilities scene environment is complex, damp, acid and alkali, salt spray, strong wind and other factors easily lead to corrosion and loosening of ordinary fasteners, drilling screw with multi-material, multi-coating category advantages, suitable for all kinds of harsh working conditions.
In the field of outdoor advertising and curtain wall decoration, the installation of metal billboards, light boxes, aluminum plastic panels on the exterior wall and metal curtain walls can effectively resist rain and dust erosion by using anti-corrosion drill tail screws, and it is not easy to rust off for a long time to reduce the safety risks of billboard falling. In the garden municipal engineering, the construction of outdoor metal guardrab, landscape steel structure and leisure facilities also rely on drilling screws to achieve rapid installation, flexible construction and strong adaptability.
For special scenes such as chemical plants and coastal cities, the stainless steel and high anti-corrosion coating drilling screw can withstand acid and alkali gas and high salt fog environment, solve the problem of easy corrosion and frequent replacement of traditional screws, and greatly reduce the maintenance cost of municipal facilities and industrial outdoor equipment.
