Product Description

PVC Profile Extrusion Line Equipment Introduction

With the growing demand for high-performance PVC profiles in industries such as construction, home furnishings, and decoration, efficient, stable, and intelligent production equipment has become a core driver of industry development. Our company's PVC Profile Extrusion Line adopts advanced twin-screw extrusion technology, equipped with high-precision servo drive systems, intelligent feeding devices, and automated auxiliary equipment. It can produce various types of door and window profiles, decorative moldings, furniture edge bands, and more, meeting customers' needs for diversified, high-precision, and energy-efficient production.

High-Efficiency Twin-Screw Extruder

Calibration and Cooling System

Mold

The heart of the production line is the SJSZ65/132 or SJSZ80/156 conical twin-screw extruder, specifically designed for PVC profiles, featuring:

Superior Plasticizing Capacity: The intermeshing twin-screw design ensures uniform material mixing and precise temperature control, effectively preventing degradation and guaranteeing profile density and surface smoothness.
Energy-Saving and Stable Operation: Driven by a servo motor, it saves over 20% energy compared to traditional asynchronous motors, with speed fluctuations ≤±0.5% and no long-term performance degradation.
Corrosion-Resistant Design: The screws and barrels are nitrided or hard-chrome plated to withstand corrosive components in PVC formulations, such as calcium carbonate and stabilizers.

6-Meter Vacuum Calibration Table: Multi-stage water-cooled vacuum calibration with high-precision temperature control (±1°C) ensures stable profile dimensions and straightness.

Modular Calibration Molds: Customized to customer requirements, allowing quick mold changes for different cross-section profiles, including complex structures (e.g., multi-chamber, hollow).

4. Haul-Off and Cutting Unit
High-Strength Belt Haul-Off: Servo-driven with a pulling force ≥5000N and speed synchronization accuracy of ±0.1%, preventing profile deformation or slippage.
Fully Automatic Cutter: Cutting length tolerance ≤±0.5mm, equipped with a dust extraction system to collect PVC particles, complying with environmental standards.

II. Technical Highlights of the Production Line
Intelligent Control

Centralized PLC and touchscreen control for real-time monitoring of extrusion pressure, temperature, haul-off speed, and other parameters, with fault alarms and data tracking.
Optional remote maintenance module for cloud-based equipment management.
Energy-Saving and Eco-Friendly Design

Servo systems and high-efficiency heating bands (energy savings ≥30%) reduce power consumption, while dust extraction minimizes workshop pollution.
High Compatibility

By changing molds and adjusting processes, it can produce solid, multi-chamber, and co-extruded profiles, suitable for PVC, ASA, wood-plastic composites, and other materials.

5. Optional Auxiliary Equipment
Crushing and Recycling System: Directly grinds scrap for reuse, reducing raw material costs.
Grinding Machine: Processes trimmings into recycled powder for non-appearance parts.
