This document discusses different materials used for washing machine drums - porcelain enamel steel drums, plastic drums, and stainless steel drums. Porcelain enamel steel drums can chip and rust over time, exposing the steel. Plastic drums are cheaper but their porous interior can absorb stains and odors. Stainless steel drums are the most expensive but are very durable, can handle higher spin speeds, and are less likely to accumulate stains or odors. The production process for drums involves several stations including straightening, cutting, folding, trimming, caulking, punching, stamping, screwing, and paddle insertion.

HOW IT IS MADE ?

2. – Over time, the porcelain enamel may chip or
wear away, exposing the steel underneath; the
exposed steel will rust, which can weaken the
tub and stain clothing.
– Porous which cause tub surfaces to absorb
stains and odors; in time, the interior of tubs
may become discolored and smelly.
– Cost: 750 USD (RM 3093)

3. – Durable and inexpensive alternative.
– the porous interior of plastic drum may become
discolored and smelly because the surfaces can absorb
stains and odors.
– Cost: 73 USD (RM301)

4. stronger and can hold up to
higher spin speeds; because
higher spin speeds remove
more water from clothes and
make laundry easier to dry.
less porous and much less likely
to accumulate stains and odors
over the life of the machine.
stainless steel drum doesn't get
rough and may in fact get
smoother as it wears, so it's
considerably less likely to
damage clothing.Cost: 2050 USD (RM8454)
