The injection moulding process is a mass series production process. It is quite possible to produce a low to very low series. We can inject moulds starting at 5 pieces. However, such a batch size has a less attractive pricing. It is important to utilise the advantages that injection moulding can offer, as quickly and efficiently as possible: a larger series with low changeover costs. The latter is partly achieved by using as few colours as possible.
Injection moulding is not expensive, but people often focus on the initial investment costs in the required injection mould. If you think in terms of 5-year sales, and divide the mould costs by the total number of products you sell over that period, it’s not that bad!
