AC Plastic Fan Blade

AC Plastic Fan Blade | Renovator Appliances Ltd

Product Overview

AC Plastic Fan Blade is a precision-moulded plastic component used in air-conditioning systems to generate and direct airflow. It is designed with a balanced blade profile and optimized geometry to support efficient air movement while maintaining stable operation and minimizing vibration and noise.

The fan blade can be manufactured according to specific diameter, blade count, blade pitch, hub dimensions, shaft mounting configuration, material, weight, balance requirements, and air-performance specifications using precision plastic injection moulding.

Manufacturing Process

The AC Plastic Fan Blade is manufactured using precision plastic injection moulding. Selected plastic granules are dried and fed into an injection moulding machine, where the material is heated to the required processing temperature.

The molten plastic is injected into a precision-engineered mould cavity containing the required blade profile, hub geometry, blade pitch, mounting bore, ribs, and reinforcement features. Controlled cooling allows the component to solidify while maintaining its aerodynamic shape.

After ejection, the fan blade is trimmed and inspected for dimensions, blade angle, hub geometry, mounting accuracy, weight, surface finish, warpage, and balance. Dynamic balancing can be performed where required for rotating applications.

Mould Manufacturing Process

The mould is developed from the required 2D drawing, 3D CAD model, blade profile, or customer specifications. Special attention is given to blade geometry, pitch angle, hub design, mounting bore, parting line, cooling channels, draft angles, and ejection system.

Suitable mould steel such as P20, H13, or S136 can be selected based on production volume, required mould life, product complexity, and surface-finish requirements.

Mould components are manufactured using CNC machining, EDM, precision drilling, grinding, polishing, and precision fitting. Trial moulding is then performed to verify blade dimensions, balance, mounting accuracy, warpage, surface quality, and moulding performance.

Raw Materials

Suitable materials may include:

• PP

• Glass-filled PP

• ABS

• Nylon / PA

• Glass-filled Nylon / PA

• Impact-modified engineering plastics

• Other application-specific engineering polymers

Material selection depends on rotational speed, operating temperature, mechanical strength, impact resistance, dimensional stability, fatigue requirements, and environmental conditions.

Quality Control

The AC Plastic Fan Blade can be inspected for:

• Overall diameter

• Blade count

• Blade pitch

• Blade angle

• Hub dimensions

• Mounting bore

• Product weight

• Blade thickness

• Concentricity

• Warpage

• Surface finish

• Flash and burrs

• Colour consistency

• Static balance

• Dynamic balance where required

• Rotational stability

Production Capacity

Production capacity depends on mould cavity count, injection moulding machine capacity, component weight, cycle time, cooling time, plastic material, balancing requirements, and machine operating efficiency.

The required injection moulding machine is selected according to the fan blade dimensions, mould size, projected area, product weight, and required clamping force.

Actual production capacity is determined after evaluating the final fan blade design, mould configuration, machine specifications, cycle time, and required production quantity.
