Product Description

Specialized in manufacturing PVC double-pipe out electrical conduit production lines, this complete extrusion system is engineered to simultaneously produce two parallel electrical conduit pipes in one pass. Designed for Φ16-Φ63mm electrical conduits, it integrates raw material mixing, dual-channel extrusion, synchronous cooling, and precision cutting. The line ensures consistent dimensional accuracy, flame resistance, and impact resistance of the pipes, fully complying with international standards.

Core Competitive Advantages

1、Dual-Output EfficiencyEquipped with a customized twin-screw extruder and dual-channel die head, it produces 2 pipes simultaneously, significantly reducing unit production costs.

2、Precise Synchronization & Uniform QualityAdopts Siemens PLC control system with synchronous speed regulation for extrusion, haul-off, and cutting. The dual vacuum calibration tanks ensure both pipes have consistent wall thickness and smooth surfaces, avoiding deformation or mismatch between the two pipes.

3、Flexible Customization

Quick-change die heads allow switching between different pipe sizes within 40 minutes. Supports production of dual pipes with the same or different specifications to meet diverse project needs.

4、Energy-Saving & Easy Maintenance

Low-power consumption motor and heat recovery system reduce energy use by 25% vs. traditional lines. Modular structure simplifies cleaning and maintenance, with key components made of high-quality alloy steel for long service life.

Key Components

CONICAL TWIN SCREW EXTRUDER

This machine is equipped with a quantitative feeding device, so that the extrusion amount and the feeding amount can be matched to ensure the stable extrusion of the product.
EXTRUSION DIE

After compaction, melting, mixing and homogenization of PVC the subsequent material is pushed to the die by the screw,The extrusion die is the most important part of tube forming.
VACUUM CALIBRATION TANK

Used for shaping and cooling of pipes, it is equipped with a vacuum system,water circulation system, as well as front and rear moving device and left and right, height adjustment manual device, stainless steel box, circulating water spray cooling.
TRACTOR

It is used to continuously and automatically lead out the cooled and hardened pipes from the machine head,and the speed is controlled by frequency conversion.
CUTTING MACHINE

After being controlled by encoder according to the required length, automatic cutting is carried out, the stacker is turned over with a delay, pipes are cutted smoothly without scraps and dust.
