Hair Dryer Plastic Inner Air Duct Mould and Moulding Service

Product Overview

Hair Dryer Plastic Inner Air Duct Mould and Moulding Service is used for manufacturing precision plastic inner air ducts designed to guide airflow through the internal structure of a hair dryer. The inner air duct helps channel air from the fan toward the heating section and outlet while maintaining the required airflow path and separation between internal components.

The air duct can be manufactured according to specific air passage dimensions, inlet and outlet geometry, fan interface, heating-element clearance, wall thickness, mounting points, airflow requirements, material, and hair dryer design using precision plastic injection moulding.

Manufacturing Process

The Hair Dryer Plastic Inner Air Duct is manufactured using the injection moulding process. Selected plastic granules are fed into an injection moulding machine and heated to the required processing temperature.

The molten plastic is injected into a precision-engineered mould cavity under controlled pressure. The mould is cooled to allow the plastic to solidify into the required duct geometry. After cooling, the mould opens and the finished air duct is ejected.

The moulded air duct is inspected for internal passage dimensions, inlet and outlet openings, wall thickness, mounting accuracy, airflow clearances, surface finish, flash, and warpage.

Mould Manufacturing Process

The mould is designed according to the required product drawing or 3D CAD model. Particular attention is given to the internal air passage, inlet and outlet openings, fan interface, heating-section clearance, guide walls, mounting bosses, support ribs, wall thickness, draft angles, parting line, cooling channels, and ejection mechanism.

Suitable mould steel such as P20, H13, or S136 can be selected according to production volume, component complexity, mould life, and required surface finish.

Mould components are manufactured using CNC machining, EDM, drilling, grinding, polishing, and precision fitting. After mould assembly, trial moulding is performed to verify filling, cooling, ejection, dimensions, airflow passage, mounting accuracy, component clearances, and assembly fit.

Raw Materials

Suitable materials may include:

• ABS

• PP

• PC

• PBT

• PA66 Nylon

• HIPS

• POM

• Engineering-grade plastics

• Heat-resistant plastic grades

• Flame-retardant plastic grades where required

Material selection depends on temperature exposure, heat resistance, mechanical strength, dimensional stability, airflow conditions, and application requirements.

Quality Control

The Inner Air Duct can be inspected for:

• Overall dimensions

• Air passage dimensions

• Inlet and outlet geometry

• Wall thickness

• Fan interface accuracy

• Heating-element clearance

• Mounting-hole positions

• Support rib dimensions

• Surface smoothness

• Product weight

• Flash and burrs

• Warpage

• Cracks and sink marks

• Assembly compatibility

Production Capacity

Production capacity depends on mould cavity count, injection moulding machine capacity, product weight, cycle time, cooling time, plastic material, and machine operating efficiency.

For example, a 2-cavity mould operating with a 35-second cycle time can theoretically produce approximately 206 pieces per hour, before accounting for downtime, inspection, material changes, and other production losses.

Actual production capacity depends on the final inner air duct design, mould configuration, machine specifications, material, and operating conditions.

Buyer Guide

When ordering a Hair Dryer Plastic Inner Air Duct Mould and Moulding Service, buyers should provide the product drawing or 3D CAD model, fan dimensions, inlet and outlet dimensions, required airflow path, heating-element position, component clearances, mounting locations, operating temperature, plastic material, colour, surface finish, expected production quantity, and assembly specifications.

These details help determine the appropriate mould design, mould steel, cavity configuration, plastic material, and injection moulding machine.
