How It’s Made: Promotional Dumbbells
Promotional dumbbells are a unique way for your brand to reach a wide audience. Dumbbells are used in a variety of settings, from gyms, to rehabilitation clinics, and even homes. Branded by Disrupt allows you to create your own branded dumbbells, and these are able to reach a huge range of people.
Promotional Dumbbells come in a variety of forms. The oldest, most traditional form is the iron dumbbell – think of the term ‘pumping iron’. Today, people pump iron with a variety of materials, including chrome, rubber, and plastic, as well as the old-school iron dumbbells. All dumbbells are composed by creating two heads, and attaching them onto a handle. We’ll start with the construction of the head.
Promotional Dumbbells Head
The head of the dumbbell is where most of the weight comes from. This weight is created in the development of the head core, which is generally constructed of cast iron, steel, or a combination material. The material used is then shaped into a circular, hexagonal, or whatever kind of shape is required for the head of a specific dumbbell.
Head Outer Material
The outer section of the head is essentially there to cover the core, create a more aesthetically pleasing product, and to provide a base on which to write the weight of the dumbbell on. The outer material is where dumbbells can differ, and is where the different types mentioned above – chrome, rubber, plastic, and iron – come in.
Promotional Dumbbells Handles
Generally, dumbbell handles are made of steel. To make them, manufactures start with a solid slab of steel. A lathe is then used to cut this slab into the cylindrical shape you will grip when lifting your dumbbell. Often you will find the handles have been knurled during the manufacturing. Knurling is a process whereby crossed lines are cut into a material in order to provide grip, as per the picture below.
Attachment of the Head and the Handles
There are a number of processes through which the head and the handles of a dumbbell are joined together. The most common of these are using an adhesive, welding the parts together, or using a screw and nut to join them. Each of these processes has drawbacks and benefits, and the best option depends largely on what environment the dumbbell will be used in. In order to compensate for various needs, a combination of these processes is often the most appropriate.
