What Kind of Plastic Material is Used for the Injection Molded Parts of Small Household Appliances?

The categories of small household appliances mainly include: microwave ovens, rice cookers, electric irons, electric heaters, vacuum cleaners, electric fans, hair dryers, water dispensers, induction cookers, electric hot pots, electric kettles, air humidifiers, electric shavers, soymilk machines, juice extractor, coffee machine. So, how to choose modified plastics for injection molded parts of small home appliances? Collected for everyone as follows:


Ⅰ. Application of plastic materials in injection molded parts of small home appliances

1. Main materials used for appearance parts


ABS: high gloss, easy to spray, but not high temperature resistance;


PP: low cost, good fluidity, but poor dimensional stability;


PC: High strength, high temperature resistance, good transparency, but easy to crack;


PC/ABS alloy: Excellent overall performance, but higher price.


2. The main materials used for decorative parts


Transparent materials: transparent ABS, PMMA, PC, etc.


Electroplating material: electroplating grade ABS


Membrane material: PET film, PC film


3. Core requirements of 3C key components


Main materials: flame-retardant PBT, flame-retardant PP, flame-retardant PPO


4. The core requirements of other key structural parts


Main materials: POM, glass fiber reinforced nylon, PPS, PPA, PEI


Ⅱ. Plastic selection of injection molded parts of common small home appliance shells

1. Injection molded parts of microwave oven shell


The plastic parts on the microwave oven are mainly external parts, such as shell, mould base, handle, knob, etc., which require heat resistance.


The selected plastics for home appliance mould are PBT/PET+GF, PBT+GF, PC/ABS, heat-resistant ABS, HIPS, heat-resistant PP, and PP.


2. Injection molded parts of rice cooker shell


The shell injection molded parts on the rice cooker are mainly external parts, including shell, base, cover, handle, switch, which require heat resistance. The selected plastics are ABS, high-gloss PP, and PP.


3. Injection molded parts of electric iron shell


The performance requirements of the plastic materials used for the injection molded parts of the electric iron shell are mainly heat resistance, followed by impact strength and appearance.


The shell, handle and sink base can be made of ABS, high-gloss PP;


The parts near the heating zone require high heat resistance. PC, PA+GF, PBT/PET+GF, PBT+GF, heat-resistant ABS can be used;


The heat resistance of the base is higher, and PBT/PET+GF, PET+GF can be used instead of metal parts.


4. Injection molded parts of electric heater shell


The plastic material used on the electric heater requires heat resistance, especially the outlet grille.


The selected plastic varieties are PBT/PET+GF, PET+GF, PC, PC/ABS, heat-resistant ABS, heat-resistant PP


5. Injection molded parts of vacuum cleaner shell


The plastic materials used for vacuum cleaner components require anti-static to avoid dust absorption. In addition, they require good electrical performance, good rigidity, impact resistance, scratch resistance, good dyeability, and gloss, especially the housing.


The selected plastics are ABS, HIPS, and high-gloss PP. Among them, the transparent parts can be PC, AS, GPPS.


6. Injection molded parts of electric fan shell


The plastic parts used in electric fans mainly include fan blades, blade covers, shell covers, knobs and so on.


The selected plastic varieties are ABS, HIPS, high-gloss PP, PP+GF, AS+GF.
