Our rigid plastic granulator machines are your ideal solution for granulating small rigid plastics such as PET preforms, various plastic blocks, and injection molded runners and reject parts. It’s a great addition to any molding or extrusion operation to directly reclaim runners, cut-offs, or resins. There’s also added sound-proofing materials throughout the cutting chamber to reduce operation noise.
In terms of usability, our rigid plastic granulator machines offers easy access to the cutting chamber and filter screen making maintenance and cleaning convenient. When the knives become blunt, the adjustable clearance between knives makes dismounting them for sharpening simple.
Make sure to look into our granulator blade sharpener machines to automate your knives sharpening process.
WORKING PRINCIPLE
The rigid plastic granulator is a heavy-duty machine for cutting all sorts of tough, rigid plastics under 2 cm thick. The claw-shape blade bed system and stepping motion of the knives adequately disperses the pressure of granulating this type of plastic improving its cutting efficiency as well as the durability of this granulator.
Unlike our standard plastic granulators that use several longer blades set in a v-shape array, our rigid plastic granulator machines make use of more than 20 smaller blades set in a stepping manner on a wide open rotor. As the rotor spins, the many blades chip away at the tough plastics continuously until they are small enough to pass through a filter screen set between 10-12 mm.
As our rigid plastic granulator machines were designed for indoor use for low volume cutting of tough plastic parts, the most powerful model can reach up to 300 kg / hr. For high volume cutting of rigid plastics, please look into our rigid plastic granulator machines XL with capacities up to 1200 kg / hr.

Frequently Asked Questions
What materials can the rigid plastic granulator process?
These machines granulate small rigid plastics under 2 cm thick — PET preforms, various plastic blocks, injection-molded runners, cut-offs, and reject parts. They are an ideal addition to molding or extrusion operations that want to reclaim runners and scrap directly at the source rather than sending them off as waste.
What capacities do the models offer?
The range runs from 50 to 300 kg/h: the WP750 (7.5 kW) handles 50–100 kg/h, the WP1100 (11 kW) 100–200 kg/h, and the WP1500 (15 kW) 200–300 kg/h. For high-volume cutting of rigid plastics, the XL version reaches up to 1,200 kg/h. Tell us your scrap volume and we will recommend the right model.
How does it differ from a standard plastic granulator?
Standard granulators use several longer blades in a v-shape array, while this rigid model uses more than 20 smaller blades set in a stepping arrangement on a wide open rotor. As the rotor spins, the many blades chip away at tough plastics continuously until particles pass through a 10–12 mm screen — a design tuned for hard, thick pieces rather than general feedstocks.
How is knife maintenance handled?
Maintenance is straightforward: the cutting chamber and filter screen are easy to access, and the adjustable clearance between knives makes dismounting them for sharpening simple. For shops that sharpen frequently, the matching granulator blade sharpener machine automates the process and keeps knife geometry consistent — which directly protects particle-size consistency.
Is the machine suitable for indoor use?
Yes. These granulators were designed for indoor, low-volume cutting of tough plastic parts, and the cutting chamber is lined with sound-proofing materials to reduce operating noise. That makes them practical to run on the factory floor near molding or extrusion lines, reclaiming runners and reject parts right where they are generated.
What warranty and certification are available?
All recycling machines come with a 1-year limited warranty, and CE certification is available. Because these are beside-the-press machines rather than full-line equipment, the key sizing questions are your thickest part (up to 2 cm), your hourly scrap volume, and your desired regrind size — send those details for a firm recommendation.
