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

Product Overview

Air Curtain Plastic Fan Blade Mould and Moulding Service is designed for manufacturing precision plastic fan blades used in air curtain systems. The fan blade is a critical rotating component that works with the motor and fan assembly to move air through the unit. Its blade profile, pitch, diameter, balance, and surface geometry can be developed according to the specific air curtain design and airflow requirements.

Renovator Appliances Ltd provides customized plastic injection mould manufacturing and moulding services for air curtain fan blades according to customer drawings, 3D CAD models, physical samples, dimensional specifications, and application requirements. The mould can be developed to maintain consistent blade geometry, hub dimensions, mounting features, and overall balance across production batches.

The fan blade can be customized with an appropriate number of blades, hub configuration, blade pitch, curvature, thickness, shaft interface, and other design features according to the approved product design. Single-cavity or multi-cavity moulding solutions can be considered depending on production volume and manufacturing requirements.

Industrial Applications

Manufacturing Process

1. Product Design & Development
The fan blade geometry is reviewed using customer drawings, 3D CAD models, physical samples, motor specifications, required airflow characteristics, blade diameter, pitch, number of blades, hub dimensions, and shaft interface. Critical areas such as blade thickness, root strength, clearances, and balance are considered during development.

2. Plastic Mould Design
A dedicated injection mould is designed according to the fan blade geometry and selected material. The tooling design considers cavity layout, parting line, gate location, runner system, cooling arrangement, ejection system, and appropriate draft angles.

3. Mould Manufacturing
The mould is manufactured using suitable mould steels such as P20, H13, or S136 according to production requirements. CNC machining, EDM, grinding, drilling, polishing, and other precision tooling operations can be used to achieve the required cavity geometry.

4. Injection Moulding
The selected thermoplastic material is heated and injected into the mould cavity under controlled processing conditions. After cooling and solidification, the fan blade is ejected from the mould.

5. Finishing & Balancing Preparation
Moulded fan blades may undergo gate removal, trimming, deburring, and other finishing operations where required. Depending on the application, rotational balance and dimensional consistency can also be evaluated.

6. Quality Inspection
Finished fan blades are inspected for blade geometry, hub dimensions, surface quality, dimensional accuracy, and compatibility with the intended motor and air curtain assembly.

Raw Materials

Material selection depends on rotational speed, motor configuration, mechanical loads, operating temperature, dimensional requirements, vibration conditions, and customer specifications.

Quality Control

Raw Material Inspection
Plastic material is checked according to the specified grade and applicable production requirements before processing.

Mould Inspection
The mould is inspected for cavity condition, blade-profile accuracy, parting surfaces, cooling arrangement, ejection system, and critical tooling dimensions.

Dimensional Inspection
Blade diameter, blade thickness, pitch-related geometry, hub dimensions, mounting interface, blade spacing, and other critical dimensions are checked against approved specifications.

Visual Inspection
Fan blades are inspected for flash, short shots, sink marks, warpage, burn marks, surface imperfections, and other visible moulding defects.

Fitment & Rotational Inspection
The fan blade can be checked for proper motor/shaft fitment, mounting alignment, clearance, and rotational balance according to the product requirements.

Packaging Inspection
Finished fan blades are packed appropriately to help prevent blade deformation, scratches, contamination, and transportation damage.
