Injection moulding of plastic parts commonly uses a two-way split mould. While this is an economical way to produce a simple mould, it offers little flexibility for meeting the differing needs of customers. The FIBOX solution is to design and mould its standard products using four-way split moulds. These moulds have multiple slides that can be individually modified according to customers’ requirements. For example, a flange interface can be added to a side of the enclosure simply by modifying one of the interchangeable slides of the mould. Customization costs are minimized as compared to creating an entirely new mould. The risks in creating a new mould are eliminated. More importantly, the time needed to get the product on the market is greatly reduced.


In addition to construction modifications, the enclosure can be moulded in a custom colour by using colour-pigmented plastic granules. This is cost effective for larger OEM production runs of at least 1000 enclosures.

Openings and knock-outs in the cover and in the bottom of the base are easily created, as FIBOX tooling offers exchangeable mould inserts (Fig.1). In order to meet customer’s requirements, the flange interface on this enclosure was added by modifying one of mould’s slides (Fig's. 2.1 and 2.2).

When opening the mould after injecting the plastic, the main parts of the mould must be opened first 1), only then can the four movable slides be opened 2).
