Basic Characteristics Of Plastic Parts in Home Appliances

Basic Characteristics of External Plastic Parts
Appearance: High surface gloss and flatness; free from bubbles or cracks. They support diverse decorative finishes-such as painting or electroplating-to align with the appliance's overall design style.
Mechanical Properties: Good impact resistance, scratch resistance, and rigidity; resistant to deformation or paint chipping from accidental bumps during daily use.
Environmental Adaptability: Basic weather resistance to withstand daily temperature fluctuations; components for outdoor or balcony appliances must also meet additional requirements for cold resistance and aging resistance.
Safety Attributes: Compliant insulation performance and adherence to basic standards for electric shock prevention and flame retardancy in appliance housings, ensuring user safety.
Common Materials: Primarily ABS, high-gloss PP, and PC/ABS alloys, which offer a balance of performance, aesthetic quality, and manufacturing cost.

 

Basic Characteristics of Internal Plastic Parts
Operational Adaptability:Precisely matched to specific internal conditions; for example, components in high-temperature zones can withstand temperatures exceeding 150°C, while parts exposed to detergents offer excellent chemical corrosion resistance.
Structural Stability: High dimensional accuracy and creep resistance; resistant to deformation over long-term use, ensuring assembly precision and operational stability for internal components.
Special Functionality: Some components possess inherent self-lubricating, anti-static, or high-insulation properties-such as POM for washing machine gears and reinforced PA for vacuum cleaner motor brackets.
Safety and Compliance:Critical live components meet stringent flame retardancy and dielectric strength requirements; food-contact components must pass safety certifications ensuring they are non-toxic and odorless.
Common Materials: Primarily engineering plastics such as glass fiber-reinforced PP, POM, PPS, reinforced PA, and flame-retardant PBT; the focus is on functional performance rather than aesthetic appearance.
