Maer WM500 TC 10 rotary cutting machine for large-mouth PET containers

Maer SA of Girona, Spain, designer and manufacturer of high-speed rotary trimmers for neck cutting of plastic bottles and containers, has released the WM500 TC 10 rotary cutting machine for the high-speed, low-cost production of PET large-mouth containers for products such as mayonnaise and sauces.

The machine is designed to cut off the dome of a PET container that was produced for blow-trim technology. This technology allows for the efficient and low-cost production of wide-mouth containers by using standard narrow-neck preforms, eliminating expensive injection-mould tooling and saving energy, resins and cycle times.

The wide-mouth finish is built into the same bottle mould rather than into the preform. The blow-moulded jar has two portions: the threaded neck finish and an upper dome that is removed in an on-line process. This provides processors with a lightweight, unbreakable jar alternative to those made of glass.

The machine is versatile, as it enables the handling of containers which do not require cutting to pass through the on-line machine, saving a bypass of the cutting machine. It can process necks with diameters ranging from 45 to 110 mm.
