Electric Rice Cooker Plastic Steam Vent Mould and Moulding Service | Renovator Appliances Ltd

Product Overview

Renovator Appliances Ltd. provides Electric Rice Cooker Plastic Steam Vent Mould and Moulding Service for manufacturing accurately moulded plastic steam vent components used in electric rice cookers and related cooking appliances. The steam vent is designed to provide a controlled passage for steam generated during cooking while supporting the appliance's overall lid and steam-management assembly.

The component can be developed according to the required vent geometry, steam passage, dimensions, mounting arrangement, locking features, surface finish, and appliance design. Injection moulding enables consistent production of steam vents with accurate openings, smooth internal passages, proper fitment, and repeatable dimensions.

Industrial Applications

Manufacturing Process

1. Product Design & Development

The steam vent is developed according to the rice cooker lid design, required steam passage, vent openings, mounting arrangement, dimensions, and assembly requirements. Wall thickness, draft angles, ribs, clips, locating features, and shrinkage considerations are evaluated during product development.

2. Plastic Mould Design

The injection mould is designed according to the steam vent geometry. The cavity, core, parting line, gate location, runner system, cooling channels, and ejection arrangement are planned to support accurate formation of the vent passages and mounting features.

3. Mould Manufacturing

The mould can be manufactured using suitable tool steel such as P20 Steel, H13 Steel, or S136 Steel, depending on production volume, mould life, dimensional requirements, and surface finish. CNC machining, EDM, grinding, polishing, fitting, and mould trials are performed as required.

4. Injection Moulding

The selected plastic material is heated and injected into the mould cavity under controlled processing conditions. Injection pressure, melt temperature, holding pressure, cooling time, and cycle time are adjusted according to the material and component geometry.

5. Finishing & Assembly Preparation

After moulding, gates and excess plastic are removed. Steam passages, vent openings, clips, tabs, locating features, and other assembly surfaces are checked and finished as required.

6. Quality Inspection

Finished steam vents are inspected for dimensional accuracy, vent-opening consistency, surface quality, warpage, flash, and proper fitment with the intended rice cooker assembly.

Raw Materials

The final material should be selected according to the actual steam temperature, moisture exposure, cleaning conditions, mechanical requirements, and location of the component within the rice cooker. For components exposed directly to hot steam, the selected grade should be validated for the actual operating conditions.

Quality Control

• Raw Material Inspection: Plastic grade, colour, and material consistency are checked before production.

• Mould Inspection: Cavity, core, vent-forming sections, parting surfaces, cooling system, and ejection system are inspected.

• Dimensional Inspection: Overall dimensions, steam openings, passages, mounting features, and critical interfaces are checked.

• Visual Inspection: Components are inspected for flash, short shots, burn marks, sink marks, warpage, scratches, and other moulding defects.

• Fitment & Functional Inspection: The steam vent can be checked for proper fitment and alignment with the rice cooker lid and associated components.

• Packaging Inspection: Finished components are protected against deformation, scratches, dust, and handling damage during storage and transportation.

Buyer Guide

When sourcing an Electric Rice Cooker Plastic Steam Vent Mould and Moulding Service, buyers should provide the required drawing, 3D model, sample, dimensions, vent-opening details, mounting arrangement, material preference, colour, surface finish, and estimated production quantity where available.

For new product development, special attention should be given to the steam passage geometry, vent openings, clearances, mounting arrangement, wall thickness, and material's resistance to the actual temperature and moisture conditions. If the component has any direct or indirect food-contact function, the material should also be selected and validated according to the applicable requirements.
