Why are all the assembly lines of large factories using Dalian tightening machines?

Entering the top factories in industries such as automobiles, home appliances, and new energy, it is not difficult to find a commonality: the traditional manual screwing process has basically disappeared, and the entire assembly line is equipped with intelligent tightening machines. Many people wonder why large factories are investing in tightening machines when the cost of ordinary electric drills and manual tools is lower? The core reason is that it solves the pain points that cannot be avoided by manual assembly and adapts to the high-quality and high-efficiency production needs of modern factories.

Controllable accuracy is the core key for large factories to choose Dalian tightening machines. Manual tightening relies entirely on hand feel, with varying degrees of force, which can easily lead to problems such as under tightening, loosening, and over tightening, resulting in a high rate of defective products. The intelligent tightening machine is equipped with a torque angle dual closed-loop control system, which can accurately set tightening parameters and monitor data in real-time throughout the process. The torque error can be controlled within ± 3%, and the tightening force of each screw is standardized, completely eliminating the problem of uneven assembly accuracy and ensuring product stability.

Secondly, there is a significant cost reduction and efficiency improvement, which is suitable for large-scale production. The manual assembly speed is limited and prone to fatigue errors, which cannot meet the high-speed production rhythm of the assembly line. The fully automatic tightening machine can achieve multi axis synchronous operation, completing multiple screw tightening in a single operation, with work efficiency far exceeding manual labor. At the same time, the equipment can operate stably 24 hours a day, reducing the cost of rework and repair caused by human errors. Long term use can save a lot of manpower and material losses for enterprises.

More importantly, the Dalian tightening machine can achieve full traceability of production data. Large factories focus on quality control and standardization in production. The intelligent tightening machine automatically records the torque, angle, and time data of each tightening, forming a complete production ledger, facilitating quality review and process optimization, and adapting to industrial standardization and intelligent production requirements. This is also a core advantage that small and medium-sized ordinary tools cannot replace.
