Injection Molded Plastic Rotary Damper

1. Product Name
Plastic Rotary Damper with Soft-Close Gear

 

2. Product Category
Plastic Mechanical Components & Motion Control Hardware

 

3. Product Description
This rotary damper is a precision-molded component equipped with an integrated internal damping fluid chamber and an external drive gear. Designed for smooth rotational resistance, it controls the closing velocity of lids, doors, and drawers to achieve a quiet, high-end soft-close experience. Crafted via single-color plastic injection molding, the housing and gear offer high structural rigidity, wear resistance, and long-term leak-proof reliability under continuous operating cycles.

 

4. Main Application
Automotive glove boxes, center console lids, household appliance doors (microwave ovens, washing machines), sanitary toilet seats, and office furniture cabinets.

Material

POM

Material Characteristics

POM provides exceptional dimensional stability, high stiffness, and a very low friction coefficient, which is critical for smooth gear meshing and long-term wear resistance during continuous rotational movement.

Special Requirements

High-temperature resistant polymer grades available for automotive interior applications; leakage-proof ultrasonic welding compatibility.

Manufacturing Process
