Base POM resin
Without a dominant wear, electrical or impact gap, establish molding and dimensional baselines with base POM. If sticking, tooth wear or load deformation emerges, move to lubricated or reinforced formulations.
Material selection for washing machine components
Washing Machine Components
Drive parts face starting impact and tooth wear; drain and valve parts depend on fit and sealing after hot-water and detergent exposure. Build separate shortlists for dry and wet service.

Typical components
Material requirements for washing machine parts
Water inlet & distribution
Hot-water and fluid exposure can alter sealing dimensions; repeated actuation wears mating surfaces. Balance dimensional retention and starting force, then leakage after pressure cycles.
Water pipes
Uneven shrinkage across ports shifts seals; hot-water cycles alter fits. Balance filling with warpage control; check leakage after detergent exposure.

View materials & gradesDrum drive
For continuous meshing, control tooth heat and wear; for starts or reversals, balance root loading with impact toughness.
Drum Drive Gear
Spin-cycle starts add impact and cyclic loads; tooth wear adds noise. Balance root capacity with wear resistance; check assembly clearance after vibration.
Precision plastic gears
Wear-resistant & low-friction POM
For meshing or sliding wear and clearance growth, shortlist MoS₂-modified EMS102 and EMS162. Start with EMS102 for flow-sensitive molding and EMS162 when tensile strength leads selection.
For low-speed starts, dry sliding or stick-slip noise, start with PTFE-modified EPTL402. Compare starting force, running torque and wear separately for steel–plastic and plastic–plastic pairs.
View materials & gradesGlass fiber reinforced POM
For load deformation or location drift, compare EGH302H (15% GF) with EGH602H (30% GF). Alongside stiffness, check orientation-driven warpage, assembly toughness and mating-surface wear.

Hot-water and fluid exposure can alter sealing dimensions; repeated actuation wears mating surfaces. Balance dimensional retention and starting force, then leakage after pressure cycles.
Drainage pump housing
Chamber and flange warpage disrupts sealing; hot water and detergent complicate dimensional control. Compare stiffness and toughness, then sealing under pressure differential.
