maybe you find many many products around you contain plastic parts, for example, handset, telephone, iphone, ipad, ipod, Walkman, DVD player，TV set，HI-FI set，laptop，refrigerator and so on, why our manufacturer use plastic parts on them？because There are numerous reasons why replacing metal parts with plastic makes sense. One of them is to decrease piece part prices

in molding industry, we always say: “A penny saved is a penny earned.” You know, for a mass molding production, we just need to pay an initial tooling cost, then we will get all the parts we need after completing molding process, so the piece part pricing is usually much less than the same part produced in metal, because the injection molding process has faster cycle times (more parts made per machine hour),

for a metal part, it could be a stamping, casting or a die cast part, the cost also can be saved, but in order to get a qualified product, it could contain secondary machining cost.
