How to choose a suitable automatic screw machine for your product?
Currently, there are mainly two types of screwdriver machines on the market that offer relatively high cost-effectiveness. So, which type of screw fastening machine is more suitable for your product and production requirements?
When choosing an automatic screw locking machine, both the air suction type and the air blowing type have their own advantages and disadvantages. Here is a detailed breakdown for you:
Air Suciton-type Screw Driving Machine
Advantages: It is especially suitable for handling small-sized and short-length screws. The equipment has excellent versatility and good stability. Within the allowable torque range, if you need to change the screw specification (for example, switching from M2 to M3), you only need to simply replace the feeder, the screwdriver bit, and the suction nozzle, and the operation is convenient. Even if the cap of screws of the same specification are different, the feeder can still be used universally, which greatly reduces the equipment adaptation cost and time cost.
Disadvantages: Due to the additional step of sucking the screws, its locking speed is slightly slower than that of the blowing-type screw locking machine. However, compared with manual screw locking, the efficiency has been significantly improved.
Air Blowing-type Screw Fastening Machine
Advantages: It has extremely high screw fastening efficiency. The screws can be directly blown to the locking nozzle, eliminating the suction action. The fastest speed can reach one screw locked per second, which greatly improves the production efficiency and is very suitable for large-scale and high-efficiency production scenarios.
Limitations: It has strict requirements for screw specifications. The total length of the screw must be more than 1.3 times the length of the nut, otherwise it cannot be applied. At the same time, it has extremely high requirements for screw precision. If the screw quality is uneven and the consistency is poor, it is very easy to cause the problem of material jams in the clamping nozzle and the feeder. In addition, when changing the screws, the feeder, the feeding pipe, the clamping nozzle, and the screwdriver bit need to be replaced simultaneously. Not only is the operation complicated, but the cost is also relatively higher.
In summary, if you value the stability of equipment operation more, or if the screw specifications are frequently changed during production, the suction-type screw driving machine is an ideal choice. If you pursue ultimate production efficiency and the screw specifications used in production meet the requirements and the quality is stable, the air blowing-type screw fastening machine can better meet your needs.
