Rice Cooker Shell Plastic Tools & Parts Injection Mold Part

Core Competencies

• Heat-resistant appliance mold manufacturing technology: For the steam high-temperature environment of rice cooker housings, mold steel utilizes corrosion-resistant pre-hardened grades, processed through precision temperature control systems and wear-resistant surface treatments to ensure cavity dimensional stability under long-term thermal cycling, with molded parts achieving heat deflection temperatures at material-rated values.
• Complex structure molding capability: Housings often feature steam channels, reinforcing ribs, metal heating plate anchoring points, and multidirectional clips. The mold employs large slides, angled lifters, and internal corepulling mechanisms to ensure smooth undercut ejection and accurate assembly interface dimensions for subsequent inner pot and control module mounting.
• Rich surface treatment processes: Supports various mold surface treatments, including high-gloss polishing, grain etching, and soft-touch coating, producing housing components with flat surfaces anda comfortable touch that align with home appliance industrial design aesthetics.
• Onestop component delivery: Beyond mold manufacturing, capabilities extend to plastic welding and assembly, completing housing to steam valve welding and metal heating plate insert molding to reduce client supply chain management costs.

Technical Specifications

• Heat-resistant insulation: Utilizes heat-resistant grade engineering plastic formulations, with molded parts maintaining dimensional stability and odor-free performance under long-term steam exposure (typically 100120℃), dielectric strength meeting home appliance safety standards.
• Dimensional stability: Scientifically arranged cooling channels combined with hot oil or steam mold temperature control technology effectively control shrinkage rates in large housing injection molding, ensuring dimensional consistency across high-volume production and preventing warpage deformation that compromises sealing performance.
• Surface consistency: Specially treated mold cavities produce components free of flash, sink marks, and gas lines, with scratch resistance achieving pencil hardness 2H or above to meet consumer-grade appliance appearance standards.
• Insert compatibility: Mold design reserves metal insert molding mechanisms, supporting stainless steel heating plates, grounding tabs, and other inserts to be simultaneously embedded during injection, ensuring pullout force and thermal conductivity meet design requirements.

Application Scenarios

• Rice cookers: Applicable to housings, bases, and control panel frames for mechanical, microcomputer, and IH electromagnetic heating rice cookers.
• Electric pressure cookers: Mold manufacturing for pressure cooker housings and steam valve components, meeting high-pressure sealing and explosion-proof design requirements.
• Electric steamers and slow cookers: Housing components for multifunction cooking appliances, meeting steam flow guidance and heat insulation requirements.
• Commercial kitchen appliances: Mold development for restaurant-grade large rice cookers and warming buckets, meeting high-frequency usage and easy-clean design requirements.
• Home appliance accessory market: Custom housing mold development and production services for appliance brands.

FAQ & Solutions

Q1: Surface gas marks or weld lines on rice cooker housings after molding, how to resolve?
Solution: This typically results from inadequate venting in steam channel areas or low melt temperature. We incorporate venting grooves and porous steel inserts at steam outlets and rib intersections during mold design, optimizing hot runner gate placement to avoid visible weld lines from melt front convergence; simultaneously guiding clients to increase mold and melt temperatures to ensure flat, defect-free surfaces.
Q2: Uneven gaps between the housing and the metal inner pot after assembly, causing steam leakage. What causes this?
Solution: This often relates to unbalanced mold cooling or shrinkage prediction deviation. We utilize moldflow analysis software to simulate the molding process, optimizing cooling channel layout and mold temperature curves, with beryllium copper inserts at critical mating surfaces to accelerate cooling and shape retention; conducting full dimensional inspection after molding to ensure profile conformity to sealing design requirements.
Q3: For molds exported to Europe, how can compliance with food contact material regulations and electrical safety standards?
Solution: Leveraging 15 years of export experience, our mold designs fully comply with DME and HASCO standards, and we can cooperate with clients to select steel grades and surface treatments meeting EU 10/2011 food contact regulations. We provide complete mill certificates, heat treatment reports, and mold maintenance manuals, with critical wear parts adopting standardized designs for local procurement and replacement, ensuring long-term stable mold operation.
