Product Design and Development
Innovative product ideas developed to our customers needs.
Through acquisition and organic growth, Polywest has been a manufacturer of high quality rotationally molded plastic products for over 30 years.
We manufacture for a wide range of industries including marine, recreational vehicle, industrial, agricultural, sewer, water and others. Recognized as a leader in the rotational molding industry we work hard to provide our customers with the optimum solutions for their product needs – whether that is a simple storage tank or an intricate component of a motor home or boat.
Plastic is replacing traditional materials and rotational molding of plastic allows unlimited opportunity for new product solutions to be developed for many industries.
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.
Unlike most metals, plastics can be colored prior to fabrication, eliminating the need for certain post-treatment processes, such as painting.
Plastics typically weigh less than metals of comparable dimensions.
Plastics are generally less susceptible to damage from chemicals or chemical reactions, such as oxidation or rusting, than metals.
Plastic fabrication often involves quick cycle times and fast turnover rates.
