I chose Roto Dynamics as my plastics manufacturer as they have been very helpful in making my design idea a reality, fabricating a mold and advising on improvements and ultimately producing a functional heavy duty product. Roto Dynamics is a dedicated professional who went out of his way to reassure me with all my queries and solve all the initial hiccups that is expected when starting up a business. I would recommend Roto Dynamics to anybody who is looking to produce their products by the rotational molding method in the United States.
