High-Performance Motors for Plastic Processing
India's ₹3 lakh crore plastic industry demands motors that can handle the extreme starting loads of injection moulding and the continuous duty of extrusion — without interrupting your production cycles.
Why This Application Demands Specialized Motors
Plastic processing machinery places severe demands on motors. Injection moulding machines require very high starting torque to generate clamping pressure. Extrusion screws need consistent torque across wide speed ranges. The heated barrel environment raises ambient temperatures around the motor. Frequent colour and material changeovers demand rapid speed adjustments. Indian plastic processors often run 24-hour shifts during peak demand.
How Sun Star Motors Solves It
Sun Star Motors™ heavy-duty and standard motors power injection moulding machines, extruders, and blow moulding equipment across India. Extra-high starting torque handles the clamping force requirements of injection moulding. VFD compatibility enables precise screw speed control for consistent melt quality. Class F insulation withstands the elevated ambient temperatures near heated barrels. Available from 0.5 HP for small tabletop machines to 20 HP for production extruders.

Best Motors for Plastic Processing Motors

Standard Motor
The workhorse of the industrial world. Our standard AC induction motors are engineered for the relentless demands of conveyors, compressors, and pumps. Built with high starting torque and a robust cast iron frame, these motors provide the consistent power needed to keep your primary machinery running without failure.

Heavy Duty Motor
Built for the extremes of mining, steel mills, and cement plants. Our heavy-duty motors feature reinforced bodies and shafts to handle massive starting loads and high-torque crushing operations. VFD-compatible and S1-rated for continuous duty in the most punishing industrial environments.

Standard Three Phase Motor
Balanced, constant-torque power for heavy industrial loads. Our three-phase motors ensure smooth operation across textile machinery, plastic processing, and hydraulic power packs. The self-starting design and balanced load distribution minimize electrical stress while maximizing mechanical output.

Foot Cum Flange Mounted Motor
Precise alignment for direct-drive applications. This hybrid mounting design eliminates the need for separate base plates, ensuring perfect structural alignment with gearboxes and hydraulic pumps. The secure B5 flange provides a vibration-resistant connection for high-efficiency power transmission.
