Which technique is best for manufacturing plastic bins?

Blow moulding is particularly suited for manufacturing hollow plastic items such as bins, bottles, and containers. This technique involves inflating a heated plastic tube (parison) within a mould to form the desired shape. The primary advantage of blow moulding is its efficiency in creating lightweight, robust, and seamless containers, which is ideal for applications like storage bins where durability and weight considerations are essential.

Additionally, blow moulding allows for the production of larger parts compared to some other methods, making it well-suited for items like plastic bins that may need to accommodate substantial volumes or are intended for storage purposes.

In contrast, techniques like injection moulding, while versatile and widely used for a variety of plastic products, are typically associated with creating solid objects rather than hollow ones. Rotational casting is primarily used for larger, hollow items but is often less efficient for high-production runs. Compression moulding is generally reserved for specific thermosetting materials and is not the best fit for creating hollow plastic bins.
