Introduction to the Design Guide

Introduction

This document is a significant revision of ARM's "green book," The Introductory Guide to Designing Rotationally Molded Plastic Parts, originally published in 1982. A number of ARM members contributed to the original publication, including significant work by Glenn Beall.

The revision was written by Dr. Nick Henwood with contributions from the ARM Education Committee.

The publication is dedicated to the memory of Tom Wyszynski, who assisted with rewriting the guide.

This Design Guide answers the following four basic questions, and many others:

• What is the rotational molding process?
• What are its advantages to users?
• How do you design rotationally molded parts?
• What plastics can be molded?

You should find this guide useful whether you are a designer, a specifier, or a buyer of rotationally molded parts. The sections which follow will provide a better understanding of rotational molding, what it offers the design engineer, the unique capabilities of the process and the inputs required to successfully design parts.
