Are Plastic Gear Racks Suitable for Packaging Lines?

Plastic Gear Rack is a type of rack made from plastic, used to transmit power and motion. It is integral in applications where lightweight, corrosion resistance, and low noise are required.

Structure and Materials

A. Composition of Plastic Gear Rack

The basic structure of a Plastic Gear Rack consists of a series of teeth and gaps that interlock with the teeth of a gear to transmit force and motion. The design of the rack and the tooth profile is crucial for ensuring efficient power transmission and optimal performance.

B. Commonly Used Plastic Materials

Common plastic materials used for gear racks include polyamide (PA), polyethylene (PE), and polypropylene (PP). These materials are chosen for their excellent mechanical properties, such as durability, flexibility, and resistance to wear and chemicals.
