Durable Design: Stainless Steel Tanks & Hardened Alloy Steel Screw
Product Introduction

Engineered for exceptional durability and longevity, this production line features core components manufactured from premium industrial materials to ensure long-term stable operation with minimal maintenance requirements. All water tanks (primary cooling, secondary setting) are constructed from corrosion-resistant 304 stainless steel, while the extruder's core screw and barrel utilize 38CrMoAlA alloy steel treated with nitriding for superior surface hardness and outstanding wear resistance. This robust material selection ensures reliable performance in demanding production environments, delivering a service life that significantly exceeds industry standards.

Frequently Asked Questions
What are the advantages of using stainless steel water tanks compared to ordinary painted steel plate tanks?
The primary advantage is exceptional corrosion resistance. During PP production, cooling water is used continuously. Ordinary steel is prone to rust, and rust particles can contaminate products and clog pipelines. 304 stainless steel eliminates corrosion issues entirely, is easy to clean, ensures product cleanliness and long-term cooling system functionality, and is ideal for production environments with stringent hygiene requirements.
How much does nitriding treatment extend the screw's service life?
Nitriding creates an extremely hard nitride layer on the screw surface, significantly enhancing wear and corrosion resistance. Under normal use with PP materials (without excessive filler or regrind), a nitrided screw's lifespan can be extended by 50% to over 100% compared to standard carburized screws, substantially reducing the frequency and cost of replacing this critical component.
Does this durable design mean the equipment price is much higher?
While the initial investment may be slightly higher than equipment using standard materials, from a Total Cost of Ownership (TCO) perspective, it is more economical. Longer component life means less downtime for replacements, reduced spare part consumption, and lower maintenance costs. Considering the gains in production efficiency and operational stability, this represents a highly valuable investment.
