What kind of plastic is used to make electrical enclosures?
The classification of small household appliances mainly includes: microwave oven, rice cooker, electric iron, electric heater, vacuum cleaner, electric fan, hair dryer, water dispenser, induction cooker, electric hot pot, electric kettle, air humidifier, electric shaver, soymilk machine, juicer, coffee machine and so on. So, how do modified plastics choose their shells and other parts? Wei Bianxiao collected the following for everyone:

1, Application of plastic materials in small household appliances

① Main materials of appearance parts

ABS: high gloss, easy to spray, but resistant to low temperature;

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 comprehensive properties, but expensive.

(2) the main materials of decorative parts

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

Electroplating material: electroplated ABS

Film materials: PET film, PC film.

③ Core requirements of 3C key components

Main materials: flame retardant PBT, flame retardant PP and flame retardant PPO.

④ Core requirements of other key structural parts

Main materials: polyformaldehyde, glass fiber reinforced nylon, polyphenylene sulfide, PPA and Pei.

2. Selection of common plastic materials for small household appliances

(1) microwave oven

The plastic parts on the microwave oven are mainly external parts, including shell, base, handle, knob and so on. This requires heat resistance.

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

(2) rice cookers

The plastic parts on the rice cooker are mainly external parts, including shell, base, cover, handle, switch and so on. This requires heat resistance. The selected plastic varieties are ABS, high-gloss PP and PP.

(3) Electric iron

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

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

Parts near the heating area require high heat resistance, and PC, PA+GF, PBT/PET+GF, PBT+GF and heat-resistant ABS can be used.

The base requires high heat resistance, and PBT/PET+GF and PET+GF can be used instead of metal parts.

(4) electric heater?

The plastic material used on the electric heater requires heat resistance, especially the style grid.

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

(5) Vacuum cleaner

The plastic material used for the parts of vacuum cleaner requires anti-static to avoid dust absorption. In addition, it also requires good electrical performance, good rigidity, impact resistance, scratch resistance, good dyeability and luster, especially the shell.

The selected plastic varieties are ABS, HIPS and high-gloss PP, and the transparent part can be PC, AS and GPPS.

(6) Electric fan

Plastic parts used for electric fans mainly include blades, leaf covers, shell covers and knobs.

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

(7) hair dryer

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

(8) Drinking machine

The plastic parts on the water dispenser require good rigidity, high gloss and impact resistance.

The selected plastic varieties are ABS, HIPS and high-rigidity PP.

(9) Induction cooker, electric hot pot

The selected plastic varieties are heat-resistant ABS and high-gloss heat-resistant PP.

(10) electric kettle

The selected plastic varieties are PC/ABS, heat-resistant ABS and high-gloss heat-resistant PP.

(1 1) air humidifier

The selected plastic varieties are: transparent parts (PC, GPPS) and opaque parts (ABS, high-gloss PP).

(12) juicer and soymilk machine

The selected plastic varieties are: transparent parts (PC, AS, GPPS) and opaque parts (ABS, high-gloss PP).

(13) coffee machine

The selected plastic varieties are: transparent part (PC), opaque part (ABS, high-gloss PP).

(14) electric shaver

At present, the plastic parts of small household appliances on the market generally include PP, ABS, PC/ABS, PC, PBT, PET, PBT/PET and so on. Not only are there many kinds of plastics used in different small household appliances, but also the modified plastics used in different parts of a small household appliance are different, and there will be differences in color.
