But now let’s look at …

Manufacturing Of Motorcycle Helmets – The Outer Shell: 

Thermoplastic Shells

Thermoplastic shells

Injection moulding is the process generally used to manufacture thermoplastic shells (Hartung 1981). Molten polymer is injected into a die which contains a negative and positive mould at a pre-determined temperature and pressure. The molten polymer is then allowed time to cure. The space between the positive and negative moulds forms the thickness of the shell (Shuaeib et al. 2002b). The advantages and disadvantages of manufacturing thermoplastic shells for motorcycle helmets are outlined in Table 1 on our website.

Advantages

1. Lighter than composite shells
2. Low manufacturing cost and reduced labour due to machinery use
3. The manufacturing method produces even shell thickness
4. Good accuracy of helmet dimensions requires no additional finishing processes, i.e., trimming, machining or grinding

Disadvantages

1. Require a large shell thickness for sufficient impact strength which increases weight and cost
2. Polycarbonate (PC) shells are difficult to process
3. PC material is susceptible to organic solvents or lacquers
4. Relatively poor shock-absorbing capacity
