Tightening machine selection guide: from manual to automatic, which one is more suitable for your production needs?

The selection of a suitable Dalian tightening machine should be based on the core requirements of the production scenario, and the gradient selection from manual to automatic is essentially a process of balancing efficiency, accuracy, and cost.

The manual tightening machine is suitable for simple assembly scenarios with small batches and multiple varieties. Its core advantage lies in high flexibility, with a unit price usually only 1/10 of automatic models, and no need for complex installation and debugging. The common preset torque wrench limits the maximum torque through mechanical structure and relies on manual touch for operation, making it suitable for scenarios such as furniture assembly and small mechanical maintenance. However, it should be noted that the fatigue caused by manual operation can lead to accuracy fluctuations (with an error of about ± 15%), and it is difficult to exceed 500 lock payments per day. Only workshop style production with a daily demand for fasteners less than 300 is recommended.

The semi-automatic Dalian tightening machine is a transitional choice that adds torque monitoring function on the basis of manual operation. The operator holds the electric screwdriver to complete the tightening process, and the equipment displays the torque value in real time with sound and light alarms. The accuracy has been improved to ± 8%, making it suitable for small and medium-sized production with basic quality requirements (such as home appliance assembly). Its procurement cost is about 3-5 times that of manual models, but it can meet basic traceability needs through data recording, with a daily processing capacity of up to 1000-2000 times.

The fully automatic tightening machine is the core equipment for large-scale production. Equipped with a servo system and visual positioning, it can automatically complete the entire process of grasping, alignment, and tightening, with an accuracy controlled within ± 3%, suitable for high-precision scenarios such as automotive engines and aerospace components. When multi axis linkage design is adopted, the daily average production capacity of a single equipment can reach more than 10000 times, and full data traceability can be achieved through the industrial Internet. However, it should be noted that fully automatic models need to be matched with standardized components and assembly lines. The initial investment is 10-50 times that of manual models, making them more suitable for stable production scenarios with large quantities and high precision.
