Spot Clinching Machine Spiro Litelocker

Spot Clinching Machine Spiro Litelocker


Spiro Litelocker is a compact and reliable machine for cold “button-lock” (clinch/press-join) connection of sheet materials. It provides a joint of up to three layers of metal through cold forming without damaging the coating or heating the material. Powered by a pneumo-hydraulic system, the working stroke and pressing cycles are configured to produce clean, corrosion-resistant, and strong joints without the need for rivets or pre-drilling holes.

Features and Advantages

Feature Advantage
Cold Forming No heat is applied, ensuring there is no thermal impact on the material's protective coating.
No Consumables Eliminates the need for drilling or rivets—saving time and materials while maintaining surface integrity.
Pneumo-Hydraulic Drive Delivers stable, repeatable pressing force with a low noise level.
Multi-Layer Support Ability to reliably join up to 3 sheets simultaneously.
Low Maintenance Low energy consumption and minimal service requirements result in low operating costs.
Shape Versatility Suitable for both rectangular and circular elements (e.g., ducts and fittings).
