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

Product Overview

Renovator Appliances Ltd manufactures Air Circulator Plastic Fan Housing Mould and Moulding Service for injection-moulded fan housing components used in air circulator assemblies. The fan housing provides structural support and positioning around the fan and motor assembly while helping maintain the required airflow path and clearance around rotating components.

The mould is developed according to the fan diameter, motor dimensions, blade clearance, housing depth, airflow direction, grille interfaces, mounting points, and overall equipment geometry. Precision injection moulding provides consistent housing dimensions, accurate mounting features, controlled wall thickness, and reliable assembly fitment.

Industrial Applications

Manufacturing Process

1. Product Design & Development

The fan housing is developed according to the fan diameter, blade profile, motor dimensions, shaft position, required radial and axial clearances, airflow direction, grille interfaces, and mounting arrangement. The design also considers vibration, heat generated by the motor, assembly sequence, and access for servicing where required.

2. Plastic Mould Design

The mould is designed around the housing's internal cavity, external profile, mounting bosses, ribs, grille interfaces, cable passages, and locating features. Gate and runner placement, cooling channels, venting, and ejection are optimized to maintain dimensional stability and reduce warpage in the housing.

For larger or deeper housing sections, mould design focuses particularly on balanced filling, cooling uniformity, and wall-thickness control to maintain fan concentricity and assembly alignment.

3. Mould Manufacturing

The mould can be manufactured using P20, H13, or S136 Steel, depending on production volume, plastic material, surface-finish requirements, component complexity, and expected mould life. CNC machining, EDM, polishing, fitting, and mould trials are used to produce the required cavity geometry.

4. Injection Moulding

The selected plastic material is processed using controlled injection pressure, melt temperature, holding pressure, cooling time, and cycle parameters. Process conditions are optimized to maintain housing roundness, mounting dimensions, fan clearance, and consistent wall thickness.

5. Finishing & Assembly Preparation

Moulded fan housings are inspected for flash, gate marks, sink marks, short shots, warpage, and surface defects. Gates are trimmed where necessary, and mounting holes, bosses, grille interfaces, and internal clearances are checked before assembly.

6. Quality Inspection

Critical dimensions such as housing diameter, depth, fan clearance, motor mounting position, grille interface, boss location, wall thickness, and overall alignment are inspected. Assembly trials with the fan, motor, front grille, and rear grille can be performed to verify complete fitment.

Raw Materials

The final material should be selected according to motor temperature, vibration, mechanical loads, impact requirements, airflow conditions, and applicable product-safety requirements.

Quality Control

• Fan housing diameter and profile inspection

• Fan blade radial and axial clearance verification

• Motor mounting-position inspection

• Front and rear grille interface checks

• Mounting-hole and boss-position inspection

• Wall-thickness consistency checks

• Housing roundness and concentricity verification

• Warpage and deformation inspection

• Flash and gate-mark inspection

• Surface-finish inspection

• Cable-routing and opening verification where applicable

• Complete assembly fitment testing

• Vibration and temperature validation

• Batch-to-batch dimensional monitoring

Buyer Guide

When sourcing an Air Circulator Plastic Fan Housing, buyers should provide the fan diameter, blade dimensions, motor dimensions, shaft position, required clearance, housing depth, grille interface, mounting arrangement, plastic grade, surface finish, and production quantity.

For new mould development, a 2D drawing, 3D CAD model, physical housing sample, fan assembly, or complete air circulator assembly can be used as a reference. The housing should be validated with the actual fan and motor assembly to confirm clearance, concentricity, vibration performance, and airflow-related fitment.

Frequently Asked Questions

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

It provides structural enclosure and positioning around the fan and motor assembly while maintaining the required clearances and airflow path.

2. How is fan clearance maintained inside the housing?

The housing is designed according to the fan diameter, blade height, axial movement, motor position, vibration, and required operating clearance to prevent contact with rotating components.

3. Which plastic material can be used for a fan housing?

PP, ABS, HIPS, PC+ABS, Nylon, Glass-Filled Nylon, or suitable flame-retardant plastics may be considered according to the required strength, temperature, impact, vibration, and safety requirements.

4. Can the housing be designed to integrate with front and rear grilles?

Yes. The housing can include dedicated grooves, mounting bosses, clips, locking features, or other interfaces required to connect the front and rear grille assemblies.

5. Can Renovator manufacture the fan housing from an existing sample?

Yes. An existing housing, complete fan assembly, 2D drawing, or 3D CAD model can be used as a reference for mould development and assembly-fitment validation.
