Air Circulator Plastic Fan Blade Mould and Moulding Service | Renovator Appliances Ltd

Product Overview

Renovator Appliances Ltd manufactures Air Circulator Plastic Fan Blade Mould and Moulding Service for injection-moulded fan blades used in air circulator assemblies. The fan blade is designed to generate the required airflow by rotating around the motor shaft at the specified operating speed while maintaining accurate balance and reliable mechanical attachment.

The mould is developed according to the blade diameter, number and profile of blades, pitch, hub geometry, shaft interface, rotational direction, blade thickness, weight distribution, and required airflow characteristics. Precision injection moulding supports consistent blade geometry, dimensional stability, concentricity, and repeatable production quality.

Industrial Applications

Manufacturing Process

1. Product Design & Development

The fan blade is developed according to the required airflow, rotational speed, fan diameter, number of blades, blade pitch, hub dimensions, shaft interface, and motor characteristics. Blade geometry and weight distribution are considered to support stable rotation and the required airflow performance.

2. Plastic Mould Design

The injection mould is designed around the blade profile, pitch, hub geometry, shaft socket, blade thickness, and parting-line requirements. Special attention is given to balanced filling, cooling, ejection, and shrinkage control because even small dimensional variations can affect blade balance and rotational performance.

3. Mould Manufacturing

The mould can be manufactured using P20, H13, or S136 Steel, depending on production volume, plastic grade, required surface finish, component complexity, and expected mould life. CNC machining, EDM, precision finishing, fitting, and mould trials are used to achieve the required blade and hub geometry.

4. Injection Moulding

The selected plastic is processed using controlled injection pressure, melt temperature, holding pressure, cooling time, and cycle parameters. Process control is important for maintaining uniform blade thickness, hub dimensions, pitch geometry, and weight consistency.

5. Finishing & Assembly Preparation

Moulded fan blades are inspected for flash, gate marks, warpage, sink marks, short shots, and surface defects. Gates are trimmed where required, and the shaft socket and hub area are checked for proper fitment.

6. Quality Inspection

Finished fan blades are checked for overall diameter, blade profile, pitch, hub dimensions, shaft interface, blade thickness, concentricity, and weight consistency. Rotational balance and assembly testing with the specified motor shaft can be performed to verify stable operation.

Raw Materials

The final material should be selected according to rotational speed, blade loading, temperature, impact requirements, vibration, environmental exposure, and the complete fan assembly's performance requirements.

Quality Control

• Overall blade diameter inspection

• Blade pitch and profile verification

• Blade thickness inspection

• Hub diameter and height inspection

• Shaft-socket dimensional verification

• Concentricity inspection

• Blade-to-blade dimensional consistency

• Weight consistency checks

• Warpage and deformation inspection

• Flash and gate-mark inspection

• Surface-finish inspection

• Static and dynamic balance testing where required

• Motor shaft fitment testing

• Rotational vibration verification

• Batch-to-batch dimensional monitoring

Buyer Guide

When sourcing an Air Circulator Plastic Fan Blade, buyers should provide the required fan diameter, number of blades, rotational speed, blade pitch, airflow requirements, hub dimensions, shaft diameter and profile, rotational direction, plastic grade, and production quantity.

For new development, a 2D drawing, 3D CAD model, existing fan blade, motor assembly, or complete air circulator can be used as a reference. Blade balance should be verified with the actual motor and shaft because blade mass distribution and hub fitment directly affect rotational stability.

Frequently Asked Questions

1. What is an Air Circulator Plastic Fan Blade used for?

It is the rotating airflow-generating component of the air circulator, designed to move air according to the required fan speed and blade geometry.

2. How is fan blade balance controlled?

Balance is supported through accurate blade geometry, consistent wall thickness, controlled weight distribution, precise hub moulding, and dimensional inspection. Static or dynamic balancing can also be performed according to the application.

3. Which plastic material is suitable for an air circulator fan blade?

PP, ABS, Nylon, Glass-Filled Nylon, PC+ABS, or other suitable engineering plastics may be considered depending on rotational speed, mechanical loading, temperature, impact, and dimensional requirements.

4. Can the fan blade hub be customized for a specific motor shaft?

Yes. The hub can be designed with the required bore, keyed profile, D-shaped interface, splined interface, press-fit, or other approved shaft connection.

5. Can the fan blade mould be manufactured for high-volume production?

Yes. Single-cavity or multi-cavity tooling can be considered according to blade size, moulding-machine capacity, production quantity, cycle time, balancing requirements, and tooling economics.
