Electric Rice Cooker Plastic Inner Lid Mould and Moulding Service | Renovator Appliances Ltd

Product Overview

Renovator Appliances Ltd. provides Electric Rice Cooker Plastic Inner Lid Mould and Moulding Service for manufacturing accurately moulded plastic inner lid components used in electric rice cookers and related cooking appliances. The inner lid is positioned inside the main lid assembly and can help support the cooking chamber interface, steam-management arrangement, sealing components, and related lid mechanisms depending on the appliance design.

The inner lid can be developed according to the required dimensions, mounting arrangement, sealing interface, steam passages, locking features, surface finish, and assembly requirements. Injection moulding enables consistent production with controlled dimensions, repeatable geometry, integrated ribs and locating features, and suitable surface quality.

Industrial Applications

Manufacturing Process

1. Product Design & Development

The inner lid is developed according to the rice cooker lid structure, cooking chamber dimensions, sealing arrangement, steam path, mounting points, and assembly requirements. Wall thickness, ribs, bosses, draft angles, and shrinkage considerations are evaluated during product development.

2. Plastic Mould Design

The injection mould is designed according to the inner lid geometry. The cavity and core arrangement, parting line, gate location, runner system, cooling channels, and ejection system are planned to achieve accurate moulding of the component.

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, surface requirements, and component specifications. CNC machining, EDM, grinding, polishing, fitting, and mould trials are carried out 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 inner lid geometry.

5. Finishing & Assembly Preparation

After moulding, gates and excess material are removed. The inner lid is checked for smooth surfaces, mounting features, steam openings, sealing interfaces, clips, and other assembly-related details.

6. Quality Inspection

Finished inner lids are inspected for dimensional accuracy, warpage, surface quality, moulding defects, and proper fitment with the intended rice cooker lid and cooking chamber assembly.

Raw Materials

The final material should be selected according to the actual temperature, steam and moisture exposure, cleaning conditions, mechanical requirements, and food-contact considerations of the inner lid. General-purpose plastics should not be assumed suitable for direct food contact or high-temperature exposure without appropriate validation.

Quality Control

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

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

• Dimensional Inspection: Overall dimensions, sealing interfaces, mounting points, openings, ribs, and critical features are checked.

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

• Fitment & Functional Inspection: The inner lid can be checked for proper fitment with the main lid, sealing components, steam-management parts, and cooking chamber interface.

• Packaging Inspection: Finished components are packed to minimize scratches, deformation, dust, and handling damage during transportation.

Buyer Guide

When sourcing an Electric Rice Cooker Plastic Inner Lid Mould and Moulding Service, buyers should provide the required drawing, 3D model, sample, dimensions, mounting arrangement, sealing details, steam-path requirements, material preference, colour, surface finish, and estimated production quantity where available.

For new product development, special attention should be given to the inner lid's operating temperature, steam and moisture exposure, sealing interface, dimensional stability, cleaning conditions, and relationship with food-contact areas. The selected plastic grade should be validated for the actual application and applicable requirements.
