Moretto has introduced Hyper Cut, a high-performance grinder for processing production scrap and recycled materials in injection moulding, extrusion and blow moulding operations. The series comprises the GR5060 and GR5084 models, with throughput up to 1,200 kg/h. A 280 rpm rotor and a dedicated rotor configuration are specified to deliver double the cutting capacity of conventional grinders while operating at 60 percent lower rotational speed. The design targets consistent output quality, including dust-free regrind.
The machine is built for intensive duty with cast iron and steel components and a cast body. According to the company, energy demand is 22 Wh/kg at up to 1,200 kg/h. The cutting chamber geometry is designed to promote material pick-up from the hopper and to retain material until it passes the screen apertures. The screen surface extends to 160 degrees to balance precision and throughput.
Hyper Cut is intended for a wide range of items such as waste pieces, sprues, blown parts and films. It is positioned for both post-industrial and post-consumer recycling, supporting in-plant reuse of material.
Models and cutting configurations
The Hyper Cut series includes the GR5060 and GR5084, each with a flexible rotor that can be configured for different types of feedstock. The rotor can be fitted with 15 movable blades on the GR5060 or 21 movable blades on the GR5084, with three fixed blades included on both models. Cutting elements can be tailored to the application to achieve regrind with controlled shape and dust-free output.
- Modular Uniblade, for hollow items, jerry cans, bulky parts and films
- Stepper Multiblade, for moulded parts, preforms and packaging materials
- Pyramidal Multiblade, for parisons, sprues and hard components

Cutting performance and screening
The design of the cutting chamber and rotor is intended to improve the capture of incoming material from the hopper. Material remains in the chamber until its size allows it to pass through the screen openings. The 160 degree screen surface maximises screening efficiency without limiting output, supporting a balance of precision and throughput.

Energy use, construction and noise
The grinder is specified to deliver up to 1,200 kg/h at an energy consumption of 22 Wh/kg, which is presented as less than half that of standard solutions. The cast body and use of high-grade cast iron and steel components align with the company’s global manufacturing standards. The cast construction also contributes to quiet operation within industry-acceptable limits.
Operation, safety and control
The range includes features for daily use and maintenance: electric, servo-assisted opening and closing of the cutting chamber and feed hopper, tool-free access, and an open rotor design to support cleaning and safe maintenance. Low rotor speed reduces wear and can extend maintenance intervals.
Control is via an intuitive touchscreen panel that monitors granulator functions. Operators can adjust settings by material type and shape to optimise grinding performance. The functionalities are in line with Industry 5.0 standards. As an option, programmable grinding modes can be stored via a frequency modulator for fast recall.

Material handling and dust control
For integrated handling of regrind, an optional cyclone extractor is available. It features a soundproofed design, a rigid stainless steel pipe and full accessibility for quick cleaning. When paired with a dedicated dust collector and bag filter, the setup is stated to ensure zero dust leakage into the work environment.
