Automatic Pin Pressing Machine

In industrial production lines, every assembly step plays a vital role in ensuring the quality of the final product. One of the key steps is pin pressing, which helps secure parts in place, ensuring both assembly precision and structural durability. 

To meet this demand, ETEK has researched and developed an automatic pin pressing machine, specifically designed for high-precision assembly stages such as controller units, battery frames, and handheld devices. Automating this step not only improves productivity but also ensures mechanical durability, aesthetic appeal, and product consistency throughout the entire production line. 

Technical Features 

• Precision Pressing Position: The system utilizes Servo Pressing technology — a process that uses a servo motor-controlled press to perform pressing operations. This allows highly precise control of pressing force, stroke, and speed. The pressing cycle can be flexibly adjusted to suit different product types. 
• Real-time Force and Stroke Monitoring & Control (Servo Pressing) :The pressing system integrates sensors that accurately measure force and stroke. It ensures precise measurements, stores data, and provides detailed analysis of each machine cycle. This guarantees that pressing force and stroke remain within safe, product-specific limits — preventing errors such as inconsistent quality or material deformation. 
• Seamless Integration with Existing Production Lines: The machine is designed for easy expansion and integration into existing factory automation systems, helping businesses save on new equipment investments while optimizing operational efficiency. 
• Intuitive Display and Alerts: Equipped with an HMI screen and visual displays of pressing force and stroke, the machine allows flexible adjustments across different product models. The force and stroke readings are easy to observe, with built-in alert systems when thresholds are exceeded. 

Technical Specifications 

• Voltage: 220V
• CT: 2s/product
• Accuracy: ±0.1 mm
• Dimensions: 2139 x 1000 x 2100 mm
