Table Fan Plastic Fan Blade Mould and Moulding Service

Product Overview

Renovator Appliances Ltd. provides Table Fan Plastic Fan Blade Mould and Moulding Service for manufacturing precision plastic fan blades designed to generate airflow when rotated by the table fan motor. The Table Fan Plastic Fan Blade is a critical rotating component whose blade shape, pitch, diameter, balance, and weight directly influence airflow, noise, and fan performance. Custom moulds can be developed according to the required fan size, motor speed, blade configuration, and OEM design specifications.

Key Features

• Aerodynamic Blade Profile: The blade geometry is designed to move air efficiently as the blade rotates, helping achieve the required airflow performance.

• Accurate Blade Pitch: Blade pitch determines how the blade interacts with air during rotation. Precise moulding helps maintain consistent pitch across the complete blade.

• Balanced Construction: Proper dimensional control and uniform material distribution help maintain rotational balance and reduce unwanted vibration.

• Lightweight Design: Plastic construction provides a relatively low-weight rotating component, helping the motor operate efficiently.

• Strong Blade Structure: Suitable plastic material and appropriate blade thickness provide resistance to normal rotational and mechanical stresses.

• Smooth Surface Finish: A smooth blade surface helps maintain consistent airflow and provides an attractive finished appearance.

• Custom Blade Design: Blade diameter, number of blades, pitch, hub design, thickness, colour, and mounting arrangement can be customized.

• Consistent Production: Injection moulding provides repeatable blade geometry and dimensional consistency for large production batches.

Industrial Applications

Table Fan Plastic Fan Blades are commonly used in:

• Table Fans: The blade rotates around the motor shaft to generate airflow for room cooling and air circulation.

• Domestic Electric Fans: Plastic blades are used in household fan designs where lightweight and economical rotating components are required.

• Oscillating Table Fans: The blade assembly works together with the motor and oscillation mechanism to distribute airflow across a wider area.

• Portable Fan Designs: Lightweight plastic blades can be incorporated into compact fan assemblies.

• OEM Fan Manufacturing: Customized blades can be manufactured according to specific airflow, motor, size, and appearance requirements.

Manufacturing Process

The manufacturing process starts with the customer's blade drawing, sample, 3D model, or performance requirements. Important parameters such as blade diameter, blade count, pitch angle, hub dimensions, blade thickness, motor shaft connection, and required material are evaluated before mould development.

The selected plastic material is heated inside an injection moulding machine and injected into the precision mould cavity. The cavity forms the aerodynamic blade profile, hub, mounting arrangement, and other required features. After cooling, the mould opens and the finished fan blade is ejected.

The moulded blades are then inspected for dimensions, blade profile, balance, shaft fitting, surface finish, warpage, and moulding defects. Trial assembly and rotational testing can also be carried out to verify compatibility with the intended fan assembly.

Mould Manufacturing Process

1. Product Drawing & Sample Review: Blade dimensions, number of blades, pitch, hub design, motor shaft connection, and performance requirements are evaluated.

2. 3D CAD Blade Design: A detailed 3D model is prepared to accurately represent the required aerodynamic blade geometry.

3. Flow & Balance Consideration: Blade thickness, weight distribution, pitch, and geometry are considered to support stable rotation and consistent airflow.

4. Mould Steel Selection: Suitable mould steel is selected according to the plastic material, production quantity, component complexity, and expected mould life.

5. CNC Machining: Precision CNC machining is used to manufacture the mould cavity, core, plates, and other components.

6. EDM Machining: EDM is used for detailed hub features, narrow sections, and complex mould geometry where required.

7. Mould Surface Finishing: Cavity surfaces are polished or finished according to the required blade appearance and surface quality.

8. Mould Assembly: The mould components are assembled and accurately aligned to ensure proper blade formation.

9. Trial Injection Moulding: Initial blades are produced to evaluate filling, blade geometry, dimensions, hub fitting, and surface quality.

10. Balance & Assembly Testing: Trial blades can be checked with the intended motor assembly to evaluate fitting, rotation, and balance.

11. Final Mould Approval: Required corrections are completed before the mould is released for regular production.

Raw Materials

• PP (Polypropylene): A lightweight thermoplastic with good flexibility, chemical resistance, and easy processability. It can be considered for fan blades where low weight and suitable flexibility are required.

• ABS (Acrylonitrile Butadiene Styrene): A rigid and impact-resistant thermoplastic offering good dimensional stability and surface finish. It can be considered for fan blades requiring a more rigid structure.

• HIPS (High Impact Polystyrene): A lightweight, impact-resistant material that can be used for suitable fan blade designs where economical injection moulding and good rigidity are required.

• Nylon: A strong engineering plastic with good mechanical strength and wear resistance. It can be considered for specialized blade applications requiring higher mechanical performance.

• Engineering-Grade Plastic: Specialized reinforced or high-performance thermoplastics can be selected where higher strength, temperature resistance, dimensional stability, or rotational performance is required.

Quality Control

• Blade Diameter Inspection: The overall blade diameter is checked to ensure compatibility with the fan housing and required airflow area.

• Blade Pitch Inspection: The pitch and angular profile of the blades are checked because variations can affect airflow and fan performance.

• Hub Dimension Check: The central hub is inspected to ensure accurate fitting with the motor shaft or blade mounting mechanism.

• Rotational Balance Check: The blade is checked for uneven weight distribution or deformation that could cause vibration during operation.

• Blade Thickness Inspection: Critical sections of the blade are checked for consistent thickness and structural integrity.

• Surface Finish Inspection: Blade surfaces are inspected for flow marks, sink marks, scratches, and other visible moulding defects.

• Warpage Inspection: The blade is checked for deformation that could change its aerodynamic profile or interfere with rotation.

• Assembly Testing: Trial blades can be fitted to the corresponding motor and fan assembly to verify proper installation and rotation.

• Material Quality Check: The selected plastic grade and material consistency are monitored to maintain repeatable product performance.

Production Capacity

Production capacity depends on fan blade weight, blade dimensions, mould cavity configuration, injection moulding machine capacity, cycle time, material type, and required production quantity. Single-cavity moulds can be considered for lower-volume requirements, while multi-cavity moulding solutions can be developed for high-volume table fan production.
