Pin insertion machine
This unit is ideally used for the safety glasses industry with a self-locking pin introduced by SPIROL. The Twist-Lok pin is a replacement for common threaded screws like the hinge pins of the glasses' temples.
Screws are known to be more expensive and requires complex installations. They can also get out of the holes by themselves. These Twist-Lok pins are easily pressed into the holes, which results to a compact hinge connection that will never come loose. It offers its services in a compact and lightweight body with cost efficient head center distance adjustment to permit the use of various width glasses.
