When looking at molding options for production purposes, there are a few different methods available. Blow molding and injection molding stand as the two most common. The major difference between injection molding and blow molding is the kind of product produced. Typically, blow molding is designed to produce hollow, singular containers, such as bottles. On the other hand, injection molding is used to produce solid pieces, such as plastic products. Ultimately, blow molding is about creating a hollow product. This is also a process that has been performed for thousands of years, only blow molding originated with a manual, hand twist and physically blowing, or pushing, air into the product.
Rotational molding is a unique plastic molding process used primarily to create seamless, stress-free, hollow one-piece items. Also called rotomoulding, it is a high temperature, low-pressure manufacturing method that combines heat and bi-axial rotation.This is a cost-effective method to produce large plastic parts. Resins are added into a mold that's heated and rotated slowly, both vertically and horizontally. Various types of plastic polymers can be used in rotational molding, depending on the desired end product. A commonly used plastic is polyethylene (PE) , as it is able to withstand elevated temperatures for prolonged periods of time and is fairly inexpensive
