Description

ZSK92 Co-Rotating Twin Screw Spline Shaft | Cold Rolling Core Shaft For PP PE PVC PET Plastic Pelletizer

ZSK92 Co-Rotating Twin Screw Spline Shaft | Cold Rolling Core Shaft for Plastic Pelletizing Machine
Product Overview

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.

Unique Product Advantages
  1. 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.

  2. 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.

  3. 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.

  4. 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.

Applicable Materials & Production Fields

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
Custom Processing Guide

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.

SEO
Q1: What plastic materials fit this ZSK92 twin screw shaft?
A1: It works well for PP, PE, POM, PVC, PET and most modified plastic raw materials.
Q2: What spline production craft do we use?
A2: We use imported European CNC cold rolling equipment to form involute inner spline teeth.
Q3: What heat treatment do all finished shafts receive?
A3: Every shaft adopts full vacuum quenching to achieve consistent hardness and anti-deformation performance.
Q4: What L/D ratios match ZSK92 plastic pelletizer?
A4: Standard options include 40:1, 44:1, 48:1, custom L/D sizes available on request.
Q5: Can I get a cooling channel inside the ZSK92 spline shaft?
A5: Two options exist: solid shaft without cooling passage and hollow shaft with internal cooling system.
Q6: What screw assembly style matches this involute spline shaft?
A6: The shaft supports modular brick pattern construction for flexible screw element layout.
