# A5 Ejector Pin with Polyurethane Spring \u2013 For Blind Rivet Nuts<\/p>\n
This detailed product description presents the precision extraction mandrel belonging to the Wiel\u00e4nder+Schill XSeries professional riveting technology, specifically developed for processing Hollow Self Piercing Rivets. The premium quality tool ensures a reliable and efficient riveting process during body repair work.<\/p>\n
## Product Identifier and Key Features<\/p>\n
Product identifier: **700369**.<\/p>\n
This extraction mandrel (Extraction Mandrel) is a crucial component in riveting systems, especially in applications where rivet removal or precise positioning of workpieces is required. The integrated polyurethane spring (polyurethane spring) offers a unique advantage over traditional solutions.<\/p>\n
### Polyurethane Spring Advantages<\/p>\n
The integration of the polyurethane spring into the design of the extraction mandrel brings several functional benefits:<\/p>\n
* **Optimized Retraction:** The spring ensures fast and reliable retraction of the pin after the riveting cycle is complete, minimizing downtime.
\n* **Excellent Vibration Damping:** The polyurethane material absorbs vibrations exceptionally well, increasing tool lifespan and improving handling during high-speed operations.
\n* **Long Service Life:** Polyurethane is extremely resistant to fatigue and mechanical stress, ensuring long-term, consistent performance.
\n* **Corrosion Resistance:** The spring material resists moisture and chemicals commonly found in workshop environments.<\/p>\n
## Technical Data and Dimensions<\/p>\n
Precision manufacturing guarantees that the tool fits perfectly with compatible riveting heads and machines.<\/p>\n

## Application Area and Compatibility<\/p>\n
This extraction mandrel is designed for A5 type tools and is closely related to the technology of Hollow Self Piercing Rivets. These rivets play a critical role in joining modern vehicle body components where high strength and a clean, non-destructive joint are essential.<\/p>\n
Wiel\u00e4nder+Schill products, like this extraction mandrel, are manufactured according to OEM (Original Equipment Manufacturer) recommendations, ensuring the highest level of repair quality that complies with strict automotive standards.<\/p>\n
### The Role of the Ejector Pin in the Riveting Process<\/p>\n
During the riveting process, the task of the extraction mandrel is to hold the tool stably after the rivet has been inserted, and then precisely retract the tool for the next operation at the end of the cycle. The design equipped with a polyurethane spring is particularly advantageous in high-volume series production or large-scale repair environments that require fast cycle times. The precise dimensions of the mandrel (18.3 x 18.3 x 47.6 mm) guarantee minimal clearance and maximum efficiency during tool changes or transitions between workpieces.<\/p>\n
## Quality Assurance and Standards<\/p>\n
Wiel\u00e4nder+Schill is committed to the highest quality requirements. The quality of the manufactured tools is evidenced by internal inspections and international standards.<\/p>\n
The company holds the following certifications, which ensure the reliability of the products and the environmental responsibility of the manufacturing processes:<\/p>\n
* **ISO 9001:** Quality Management System Certificate.
\n* **ISO 14001:** Environmental Management System Certificate.<\/p>\n
These standards guarantee that during the manufacturing of the A5 extraction mandrel, strict quality control protocols are applied, ensuring consistent product performance in the body repair industry.<\/p>\n
## Summary<\/p>\n
The **A5 Ejector Pin with Polyurethane Spring, part number 700369**, is a specialized, high-performance component that is an essential part of the Wiel\u00e4nder+Schill XSeries professional riveting systems. The design, complemented by the polyurethane spring, significantly improves the tool's operating speed and durability while ensuring the precise and reliable processing of blind rivet nuts. Its compact dimensions (18.3 x 18.3 x 47.6 mm) and adherence to strict quality specifications make this component an ideal choice for professional body repair shops.<\/p>","protected":false},"excerpt":{"rendered":"
