Mirror Welding

CPL have the expertise and technology to provide Butt Fusion application, commonly referred to as Mirror Welding. This is superior to hand welding, which we also employ, Butt Fusion performs a more solid, accurate and durable welding procedure.

Butt Fusion is the process of merging two plastic items to create a new product, with a larger capacity. This is achieved by welding across the full face of a joint. Part of the process can include further welding of the internal ribs that would not be able to be welded manually.


Where an already moulded crate or box exists in its standard form and size, we have the technology to extend, reduce or modify all types of crates as required. By fusing two sections of a standard crate by welding two surfaces on a flat plane, we are able to form a bespoke specification, custom made to your very own size requirements.
