Pneumatic Rubber Ring Hole Expanding Machine

This semi-automatic pneumatic rubber ring hole expanding machine is specifically designed to enlarge the inner holes of rubber rings and grommets used for wire protection applications. The machine facilitates efficient wire insertion operations by stretching rubber components to the required dimensions.

The equipment features a four-pole pneumatic expansion system that allows operators to manually position rubber rings onto the poles and activate the expansion process via a foot switch. When activated, the four poles extend outward, transforming the circular inner hole into a square opening to accommodate wire insertion requirements.

The expansion stroke is fully adjustable through cylinder control, enabling precise customization of the enlarged hole dimensions based on specific application needs. This flexibility ensures optimal compatibility with various rubber ring sizes and wire protection requirements across different industrial applications.

Both the size and shape of the expanding poles can be customized according to customer product specifications, making this machine adaptable to diverse manufacturing environments. The pneumatic operation provides consistent and reliable performance while maintaining ease of use for operators.

Ideal for electronics manufacturing, automotive wiring harness production, and industrial cable assembly operations, this machine enhances workflow efficiency by streamlining the rubber ring preparation process for wire protection applications.
