Model 820A is a pneumatic-driven fastener insertion machine featuring an 8 t (78 kN) clamp force and a 500 mm throat. It utilizes an air-to-hydraulic intensifier to achieve a high forming force. A current-sensing anti-crush safety stops motion on abnormalities. Built-in fastener parameter charts enable quick, reliable setup.

Runs on standard single-phase mains (220 V, 50 Hz); control cabinet power ~50 W.
Uses compressed air only during insertion cycles, avoiding continuous high-power draw.
Minimal additional energy required—suitable for low-energy, green production environments.
Assisted positioning: Laser positioning provides a visual reference to help operators align large or complex workpieces.
Improved accuracy: The laser guide speeds up target acquisition and increases riveting precision and throughput.
Crafted from forged alloy steel with heat treatment, it delivers impact resistance and long-term stability. The integrated V-guide groove ensures precise tooling positioning while supporting a range of standard and custom dies for various rivet types. Designed for effortless maintenance and secure, consistent performance in single-station operations.
Advanced pneumatic riveting safety with interlocks and rapid stop on fault.
Protects operators during insertion cycles and reduces incident risk.
Enhances operator confidence and steady production.

Your questions about our fastener insertion machines, answered by our experts.
First, assess the workpiece material and thickness — stainless steel typically requires a higher-force model, while thin aluminum parts can use small- to mid-sized machines. Next, check the fastener specifications — different diameters and fastener types require matching dies and pressure settings, so confirm the machine and tooling are compatible. Finally, consider production throughput: for high-volume runs, choose semi- or fully-automatic insertion machines; for small-batch, multi-spec production, a model with flexible manual adjustments is preferable. Please provide sample parts and production requirements so our engineering team can make a precise recommendation.
Three common causes and remedies:
Die mismatch: If the die does not match the fastener specification, the rivet can misform. Replace with the correct die for the fastener.
Incorrect pressure settings: Insufficient pressure yields loose joints; excessive pressure can deform or skew the part. Adjust pressure according to material and fastener specs — start testing at about 80% of the recommended setting and fine-tune.
Poor part positioning: Loose or inaccurate fixturing causes misalignment. Verify and secure the fixture, ensure correct part placement, and, if necessary, improve locating accuracy.
