Profile: Blue-reed LLC offers plastic product design and development services. Rotational molding design leans heavily on experience to create a proper part for this process. This isn?t to say that its rocket science and that not every designer can do it. It?s to say that depending on the complexity of the part and what it?s function is, you better have some familiarity with this particular process as well as be somewhat familiar with the molder that will be molding the part. Otherwise things can get ugly in a hurry.
