Plastic is replacing traditional materials and rotational molding of plastic allows unlimited opportunity for new product solutions to be developed for many industries.
Benefits of Plastic vs. Steel
There are many reasons for using plastic over metals besides the obvious benefits of having
no rust and/or corrosion, a low noise level, and also low cost. Some other advantages of plastic are:
Ease of forming.
Due to its low melting point and high malleability compared to other materials, plastic can be formed into basic and complex geometries with relative ease.
Reduced finishing.
Unlike most metals, plastics can be colored prior to fabrication, eliminating the need for certain post-treatment processes, such as painting.
Lighter weight.
Plastics typically weigh less than metals of comparable dimensions.
Chemical resistance.
Plastics are generally less susceptible to damage from chemicals or chemical reactions, such as oxidation or rusting, than metals.
Faster production.
Plastic fabrication often involves quick cycle times and fast turnover rates.
