ZSK92 Co-Rotating Twin Screw Spline Shaft | Cold Rolling Core Shaft For PP PE PVC PET Plastic Pelletizer
This involute inner spline shaft matches ZSK92 co-rotating twin screw pelletizers for plastic granulation. It serves as the main carrier for all modular screw blocks during plastic melting, mixing and pelletizing work.
We design this shaft to satisfy heavy-load continuous pelletizing production. It holds large torque output, stable high-temperature strength and precise dimensional tolerance for long-hour plastic recycling and compounding production.

- Multi-grade alloy steel for diverse plastic materials
Three pre-hardened alloy steel grades stand ready for different processing materials. The steel base keeps stable mechanical performance when processing PP, PE, POM, PVC, PET and other plastic raw materials. It resists abrasion from mineral fillers and thermal aging under long high-temperature operation.
- Cold rolling spline eliminates element slipping
European CNC cold rolling machines shape all involute spline teeth. Even tooth contact spreads torque evenly during high-speed rotation. Modular mixing and conveying blocks lock firmly on the shaft without offset movement in long pelletizing cycles.
- Vacuum quenching boosts overall toughness
Whole shaft undergoes closed vacuum quenching. The shaft gains uniform hardness across the entire body. It withstands frequent startup torque shocks and avoids bending or cracking under heavy filler feeding loads.
- Dual structure choices for different pelletizing demands
Users pick solid shaft for regular plastic pelletizing tasks. Hollow cooling shaft fits high-filler, high-temperature formula production to lower shaft thermal expansion risk. Brick pattern screw layout supports free combination for melting, dispersion and devolatilization sections.
Current plastic pelletizing lines run faster and carry larger feeding loads. Ordinary shafts deform quickly and trigger frequent machine stops. This cold rolling spline shaft cuts maintenance downtime for pelletizing factories.
Suitable plastic raw materials: PP, PE, POM, PVC, PET
Main production scenarios:
- Virgin plastic compound pelletizing
- Waste plastic recycling granulation
- Filler-reinforced plastic masterbatch production
- Modified engineering plastic pellet making
- Replacement spare core shaft for ZSK92 co-rotating twin screw pelletizer
We manufacture spline shafts directly at factory workshop. We accept drawing customization for non-standard ZSK series pelletizer sizes.
Share your barrel inner diameter, production L/D ratio and plastic processing formula with technical staff. We select matched steel grade and spline size then provide fast quotation.
This high-strength spline shaft extends pelletizer service life and raises continuous production efficiency.
