Which of the following is NOT an advantage of Injection Moulding?

Injection moulding is a manufacturing process that involves injecting molten material into a mould to create parts. The advantages of injection moulding are closely tied to its efficiency and capability, especially in large-scale production.

Producing complex 3D shapes is indeed one of the key advantages of this process. The moulds used can be designed to create intricate geometries that would be difficult or impossible to achieve with other manufacturing methods. This flexibility in design makes injection moulding highly valuable for producing detailed parts.

Large production with consistent quality is another significant advantage. Once the injection moulds are created, they can reproduce parts with a high degree of accuracy and repeatability. This means that thousands or even millions of identical pieces can be manufactured without significant variation, making it ideal for mass production.

The ability to incorporate metal inserts is also a strong point of injection moulding. This allows designers to enhance certain features of a product, such as adding strength or functional interfaces, by combining different materials within a single moulding process.

However, the notion of low initial setup costs does not align with the advantages of injection moulding. In fact, the setup costs for creating moulds can be quite high due to the precision and tooling required. This aspect often makes injection moulding less
