Air Circulator Plastic Oscillation Gear Mould and Moulding Service | Renovator Appliances Ltd

Product Overview

Renovator Appliances Ltd manufactures Air Circulator Plastic Oscillation Gear and provides precision Plastic Injection Moulding and mould manufacturing solutions for automatic oscillation mechanisms. The oscillation gear is a mechanical transmission component that transfers rotary motion within the oscillation system to produce controlled side-to-side movement of the fan assembly.

The mould is developed according to the gear's tooth profile, module, pitch diameter, outside diameter, tooth count, bore geometry, hub dimensions, face width, and shaft interface. Accurate tooth formation, concentricity, and dimensional control are essential for smooth gear meshing, consistent oscillation, reduced noise, and reliable operation during repeated cycles.

Industrial Applications

Manufacturing Process

1. Product Design & Development

The oscillation gear is developed according to the complete transmission mechanism. Important parameters include tooth count, module, pressure angle, pitch diameter, outside diameter, root diameter, tooth thickness, face width, bore diameter, hub geometry, shaft interface, and required rotational speed and torque.

2. Plastic Mould Design

The injection mould is designed with precision gear-tooth cavity and core geometry. The gear-forming sections require accurate machining to maintain the specified tooth profile and pitch. Gate placement, cooling, ejection, draft considerations, shrinkage allowance, and core alignment are optimized to maintain gear concentricity and dimensional stability.

3. Mould Manufacturing

The mould is manufactured through precision machining and mould-making processes. P20, H13, S136, or another suitable mould steel can be selected according to production volume, plastic material, gear precision, surface-finish requirements, and expected mould life. Gear cavity and core dimensions are inspected carefully before trial production.

4. Injection Moulding

The selected engineering plastic is injection moulded under controlled processing conditions. Melt temperature, injection pressure, injection speed, holding pressure, and cooling time are adjusted according to the selected resin and gear geometry. Controlled processing helps minimize tooth deformation, sink marks, shrinkage variation, and bore distortion.

5. Finishing & Assembly Preparation

After moulding, gates, runners, flash, and excess material are removed without damaging the gear teeth. The gear is checked for clean tooth formation, bore accuracy, hub geometry, and surface quality. The component can then be prepared for assembly with the corresponding shaft, pinion, gear train, or oscillation mechanism.

6. Quality Inspection

The finished gear is inspected for tooth count, tooth profile, pitch dimensions, outside diameter, bore diameter, face width, concentricity, tooth thickness, runout, surface finish, and assembly fitment. Functional gear-mesh testing can be performed to verify smooth rotation and proper transmission of motion.

• Outside and root diameter

• Tooth thickness

• Face width

• Central bore diameter

• Shaft-interface geometry

• Hub dimensions

• Warpage and shrinkage

• Rotational smoothness

• Repeated-cycle performance

Buyer Guide

When sourcing an Air Circulator Plastic Oscillation Gear, buyers should provide the gear drawing or CAD model, tooth count, module, pressure angle, pitch diameter, bore diameter, shaft profile, face width, mating gear details, operating speed, expected load, material preference, and production quantity.

The gear should be designed as a matched transmission component with its mating gear or pinion. Tooth geometry, backlash, bore fit, concentricity, and material selection should be evaluated together to achieve smooth motion and controlled oscillation. For continuous operation, wear, temperature, lubrication conditions, and repeated-cycle performance should also be considered.
