Xiaolu has seen this kind of single-screwdriver, dual-station screw locking machine in many factories. The screw locking process may look like a small step, but in actual production, it often slows down the whole line. Operators need to load screws and handle the products at the same time. Manual screw locking is not fast enough, and once an experienced worker is replaced, the production capacity can become unstable very quickly.

As product quality requirements are getting higher, problems such as stripped screws, floating screws, loose locking, and over-tightening are also more likely to happen. That is why the market needs our Jushi 5331 desktop four-axis single-screwdriver dual-station screw locking machine. Next, let’s take a closer look at its main features and practical applications.

Main Functions of the Screw Locking Machine

1. Dual-track design allows product loading and unloading to run at the same time as screw locking, making full use of the single electric screwdriver and improving efficiency.
2. Screw picking can be done by vacuum suction or magnetic suction, suitable for different types of screws.
3. The machine supports detection functions such as missing screws and stripped screws.
4. Strong product compatibility. It can store parameters for up to 100 different products.

Applicable Industries

The desktop four-axis single-screwdriver dual-station screw locking machine can be used in many different industries. It is a flexible auxiliary automation machine that can work across various production fields. That is why many processing factories choose Jushi screw locking machines.

1. Electronics and Electrical Industry
   It can be used for PCB housings, controllers, switch panels, small electronic parts, and similar products. These products usually have many screw holes and require high locking accuracy and efficiency, so automatic screw locking machines are a good replacement for manual work.
2. Small Home Appliance Industry
   It is suitable for products such as electric fans, induction cookers, humidifiers, air fryers, soybean milk makers, and water dispensers. Small home appliances usually have large assembly volumes and repeated screw locking processes, making them suitable for dual-station automatic screw locking.
3. Hardware and Plastic Industry
   It can be used for plastic housings, hardware brackets, small metal parts, and other components. These products are updated frequently, so the machine needs strong compatibility. In this case, customized non-standard solutions have more obvious advantages.
4. Automotive Parts Industry
   It is suitable for small automotive accessories, interior parts, electronic module housings, and similar products. Since this industry has higher requirements for locking quality and consistency, automatic screw locking machines can help reduce the defect rate.
5. Communication Equipment Industry
   It can be used for routers, switches, communication module housings, terminal device accessories, and other products. These products are usually produced in large quantities and have many structural parts, so automatic screw locking solutions can improve assembly efficiency.
6. LED and Lighting Industry
   It is suitable for lamp housings, driver boxes, lighting components, and similar products. These products usually have fixed screw locking positions and are produced in batches. Using a desktop four-axis machine makes it easier to achieve standardized operation.

Solving Four Main Pain Points for Factory Owners

1. Manual screw locking is slow and inefficient. When there are many products, orders can easily get delayed. In serious cases, it may directly affect order delivery.
2. Manual screw locking quality is not stable. Problems such as stripped screws, floating screws, loose locking, and over-tightening can easily happen. This leads to a higher rework rate and makes the product yield harder to control.
3. The screw locking position is repetitive and boring. It is difficult to recruit workers, difficult to keep workers, and staff turnover is high. This also brings more pressure to factory management.
4. New workers need more time to learn. The training period is long, and when workers are not skilled enough, both production capacity and product quality can easily become unstable.

Requirements for Using the Screw Locking Machine

Our dual-station screw locking machine can be used in a wide range of industries. As long as the screw size is within M1.0 to M4.0, most products can basically be locked by this machine.

However, we do not sell the machine to every factory. Why? Because if the machine cannot meet the customer’s actual requirements, we will not force the sale. We first need to clearly understand each customer’s product, screw type, locking position, production demand, and quality requirements. Then we recommend the right machine. If it is not suitable, we would rather not close the deal.
