Rolling Shutter Insert-Molded Drive Gear

Manufacturing Processes & Capabilities

• Heavy-Duty Insert Molding: High-strength knurled metal shafts are precisely positioned inside the mold and insert-molded with impact-resistant engineering plastics (e.g., PA66+GF / POM), maximizing torsional bonding strength and anti-slip performance.

• Shrinkage & Profile Precision Control: Mold flow optimization for thick-walled and glass-fiber reinforced structures precisely controls cooling shrinkage, preventing tooth sink marks and eccentricity while ensuring high-precision meshing.

Features & Advantages

• High Torque & Impact Resistance: Engineered to withstand instantaneous peak loads and reverse shock forces during rolling shutter startup and braking, combining solid metal shaft strength with plastic shock absorption.

• Low Noise & Weather Resistance: Significantly dampens operating noise compared to all-metal gearboxes, offering excellent self-lubrication, wear resistance, and long-term durability in dusty and humid environments.
