PP Threading Bellows Production Line/Winding Bellows Processing Equipment

Zhongrui Machinery's High-Capacity Innovative Automated Bellows Production Line represents a technological leap forward in industrial manufacturing, engineered to meet the rigorous demands of modern, large-scale bellows production. This fully automated, state-of-the-art system integrates precision engineering, intelligent control, and modular flexibility to deliver unparalleled efficiency, consistency, and quality in the fabrication of various bellows types—from protective cable conduits to complex industrial expansion joints.
Designed as a complete turnkey solution, the production line streamlines the entire manufacturing process—from raw material feeding and extrusion to forming, cooling, printing, and final coiling—all within a seamlessly synchronized operation. Its advanced PLC-based control system, equipped with a user-friendly HMI interface, allows for real-time monitoring and precise adjustment of critical parameters such as temperature, speed, and tension. This ensures not only high dimensional accuracy and surface finish but also optimal material utilization and minimal waste.
A key strength of this system lies in its customizability and adaptability. The production line can be configured to accommodate different polymer materials—including PVC, PE, PP, and nylon—and tailored to produce bellows with varying diameters, wall thicknesses, and corrugation profiles. Whether for automotive wiring harness protection, construction ducting, or agricultural drainage systems, the line can be easily adjusted to meet both standard specifications and unique client requirements, making it a versatile asset across multiple sectors.
In terms of performance, the line operates with high-speed precision, capable of sustained output with minimal downtime thanks to its robust mechanical design and premium component selection. Energy efficiency is built into its core, with optimized drive systems and optional heat recovery units that significantly reduce power consumption and operational costs.
After-sales support is a cornerstone of our commitment. We provide comprehensive online technical assistance for troubleshooting, preventive maintenance guidance, and remote diagnostics to ensure continuous operation. Each line comes with a full one-year warranty, covering parts and labor, backed by our global service network for prompt onsite support when needed. All equipment is supplied brand new, manufactured under strict quality controls, and compliant with international safety and performance standards.
Ideal for manufacturers looking to scale production, enhance product consistency, and reduce labor dependency, Zhongrui’s Automated Bellows Production Line is more than machinery—it’s a partnership in productivity, designed to grow with your business and sustain competitiveness in a dynamic industrial landscape.

Product Description

Introduction

    The unit mainly uses PP and PE as raw materials to produce bellows pipe. The bellows forming head has high precision and the module interchangeability is good. Online flaming can be realized to ensure the performance indexes of the pipe forming. Bellows have the advantages of light weight, heat insulation, heat preservation, moisture proof, flame retardant, acid and alkali resistance, corrosion resistance, widely used in power cable casing, urban drainage, agricultural irrigation, buried infiltration irrigation and building water delivery fields.
