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

Product Overview

Air Curtain Plastic Fan Housing Mould and Moulding Service is designed for manufacturing precision plastic fan housing components used in air curtain systems. The fan housing provides an enclosure and structural interface around the fan assembly, helping maintain the required position of the fan and guiding airflow through the internal air path of the unit.

Renovator Appliances Ltd provides customized plastic injection mould manufacturing and moulding services for fan housing components according to customer drawings, 3D CAD models, physical samples, dimensions, fan specifications, and assembly requirements. The housing can be developed with airflow passages, fan mounting points, motor clearances, reinforcing ribs, locating features, screw bosses, clips, and other features required by the specific air curtain design.

The mould can be engineered for accurate housing dimensions, consistent wall thickness, reliable fitment, and repeatable injection moulding production. Single-cavity or multi-cavity tooling can be considered according to component size, geometry, production volume, and customer requirements.

Industrial Applications

Manufacturing Process

1. Product Design & Development
The fan housing design is reviewed using customer drawings, 3D CAD models, physical samples, fan dimensions, motor specifications, airflow requirements, mounting arrangements, and surrounding component interfaces. Critical areas such as fan clearance, wall thickness, mounting bosses, ribs, and airflow passages are considered.

2. Plastic Mould Design
A dedicated injection mould is designed according to the fan housing geometry and selected plastic material. The mould design considers cavity layout, parting line, gate position, runner system, cooling channels, draft angles, and ejection requirements.

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

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 housing is ejected from the mould.

5. Finishing & Assembly Preparation
Moulded fan housings may undergo gate removal, trimming, deburring, and other finishing operations as required. Components can then be prepared for installation of the fan, motor, and associated parts.

6. Quality Inspection
Finished fan housings are inspected for dimensional accuracy, fan clearance, mounting-feature consistency, surface quality, and compatibility with the intended air curtain assembly.

Raw Materials

Material selection is finalized according to fan speed, motor operating conditions, mechanical requirements, temperature exposure, dimensional stability, and customer specifications.

Quality Control

Raw Material Inspection
Plastic material is checked against the specified grade and applicable production requirements before injection moulding.

Mould Inspection
The mould is inspected for cavity condition, parting surfaces, cooling channels, ejection components, and critical tooling dimensions.

Dimensional Inspection
Overall housing dimensions, fan openings, mounting points, screw bosses, clearances, airflow passages, and other critical features are checked against approved specifications.

Visual Inspection
Components are inspected for flash, short shots, sink marks, warpage, burn marks, weld-line concerns, and other visible moulding defects.

Fitment & Functional Inspection
The fan housing can be checked for fan and motor fitment, mounting alignment, internal clearance, component interfaces, and compatibility with the intended airflow arrangement.

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

Buyer Guide

When sourcing an Air Curtain Plastic Fan Housing Mould and Moulding Service, buyers should consider:
