The Rheo-Pro iVG hot runner stack mould systems are said to have a 54% smaller carbon footprint than their single-face counterparts. Also, they can run in smaller injection moulding machines with less clamp tonnage, which further cuts overall energy consumption while maintaining the same high level of output and improved part quality, MHS said.

It noted that a standard Rheo-Pro iVG 48+48 stack mould, running in a relatively small 200-tonne machine, can produce 96 lightweight bottle closures every three seconds or almost three million parts per day. That is said to make it 30% more cost efficient than a conventional 96-cavity single-face system.

According to MHS, Rheo-Pro iVG hot runner systems are robust, simple to use and virtually maintenance-free by omitting wear items like seals and lubricants.
