Engineered Downstream Equipment for Profile Extrusion

Precision Crafted for Quality – Designed for Performance

Manufactured by EXTRUTEX Austria

In the world of PVC and polymer profile extrusion, downstream equipment is not an accessory—it is the silent architect of dimensional accuracy, surface perfection, and long-term production stability. While extruders shape the melt, it is the downstream line that defines whether a profile becomes a premium product or a compromised one.

EXTRUTEX Austria designs and manufactures high-performance downstream equipment for profile extrusion with a singular philosophy:
Quality over quantity. Precision over volume. Partnership over transactions.

Our downstream systems are not built for every market. They are engineered specifically for manufacturers who demand the highest levels of process stability, energy efficiency, automation, and reliability, and who compete in markets where tolerances are tight and expectations are unforgiving.

About EXTRUTEX Austria – A Different Engineering Philosophy

EXTRUTEX Austria is founded on a deliberate departure from mass-market machinery manufacturing. Rather than focusing on high sales volumes, we concentrate on engineering excellence, long service life, and uncompromising performance.

Our downstream profile extrusion equipment is supplied only to manufacturers who understand that:

• Consistent dimensional accuracy is more valuable than peak short-term output

• Stable production reduces waste more effectively than post-production correction

• True cost efficiency is measured over years—not months

Backed by decades of engineering experience, intensive R&D, and close collaboration with European technology partners, EXTRUTEX delivers downstream solutions that integrate seamlessly into modern extrusion lines—whether for PVC window and door profiles, technical profiles, WPC systems, or high-speed industrial applications.

What Is Downstream Equipment in Profile Extrusion?

Downstream equipment refers to all machinery positioned after the extruder die, responsible for shaping, cooling, pulling, cutting, and handling the final profile. These systems directly affect:

• Dimensional stability

• Surface quality

• Internal stress distribution

• Line speed consistency

• Energy consumption

• Scrap rate

EXTRUTEX downstream profile extrusion systems typically include:

• Vacuum calibration tables (dry & wet)

• Water cooling systems

• Haul-off (puller) units

• Cutting systems (saw or knife)

• Stacking or handling solutions

Each component is engineered as part of an integrated ecosystem—not as isolated machines.

Key Design Principles of EXTRUTEX Downstream Equipment

1. Engineered Energy Efficiency

Energy efficiency is not an option—it is a design obligation.

EXTRUTEX downstream systems are engineered to minimize energy consumption without compromising process stability. This is achieved through:

• Servo-controlled vacuum and drive systems

• Optimized water flow dynamics

• Intelligent vacuum zoning

• Reduced pump load through smart automation

Unlike conventional systems that run at constant maximum capacity, EXTRUTEX equipment adapts dynamically to real process demand—reducing electricity usage, heat loss, and mechanical wear.

Result:
Lower operating costs, reduced carbon footprint, and longer component lifespan.

2. Unmatched Process Stability

In profile extrusion, stability is everything. Micro-fluctuations in vacuum, water pressure, or temperature can translate into visible defects, dimensional drift, or internal stress buildup.

EXTRUTEX integrates advanced automatic control systems to maintain absolute process consistency, including:

CVR – Constant Vacuum Regulation

Automatically maintains stable vacuum levels across multiple calibration zones, compensating for line speed changes and profile geometry variations.

CWP – Constant Water Pressure Control

Ensures uniform water pressure throughout the cooling circuit, eliminating uneven cooling and surface distortion.

CWT – Constant Water Temperature Control

Actively stabilizes water temperature in cooling cycles, preventing thermal shock, shrinkage, and profile deformation.

Together, these systems form a closed-loop control architecture that protects product quality—even during high-speed operation or material variation.

3. Operator-Friendly by Design

Advanced machinery should not require advanced complexity.

EXTRUTEX downstream equipment is designed so that operators do not need deep technical expertise to achieve optimal performance. This is accomplished through:

• Intuitive touch-screen HMI interfaces

• Pre-configured process recipes

• Guided startup and adjustment menus

• Clear visual diagnostics

The system does the thinking.
The operator focuses on production.

This dramatically reduces training time, human error, and startup losses—especially valuable in high-turnover production environments.

Core Systems and Technologies Used by EXTRUTEX

Servo-Controlled Vacuum System (Siemens Technology)

At the heart of profile calibration lies vacuum precision.

EXTRUTEX uses custom-designed vacuum pumps combined with servo controllers, enabling:

• Precise vacuum level adjustment

• Fast response to process changes

• Reduced mechanical stress on pumps

Integration with Siemens control systems (Germany) ensures industrial-grade reliability, real-time feedback, and seamless automation integration.

Benefits:

• Superior dimensional accuracy

• Improved surface quality

• Reduced scrap during startup and speed changes

• Lower energy consumption compared to conventional vacuum systems

Advanced Bypass Filter System

Water contamination is one of the most underestimated causes of calibration defects and equipment wear.

EXTRUTEX integrates an advanced Bypass Filtration System that continuously removes impurities from the cooling and calibration water—without interrupting operation.

This system:

• Protects calibration plates and seals

• Improves surface finish

• Extends maintenance intervals

• Stabilizes vacuum performance

Clean water is not a luxury—it is a prerequisite for precision extrusion.

High-Performance Haul-Off Units (Pullers)

The haul-off unit is the backbone of line speed stability. Any fluctuation here directly translates into profile deformation.

EXTRUTEX haul-off systems feature:

• Fully automatic operation

• Self-tensioning chain systems for uniform force distribution

• Central motor and gearbox arrangement for balanced torque transmission

• Optimized mechanical design for easy access to puller pads (PODs)

Engineering Advantages:

• Smooth, vibration-free pulling

• Consistent line speed under load

• Faster changeover and adjustment

• Extended lifetime of wear components

These innovations reduce downtime, simplify maintenance, and ensure stable pulling force even in high-speed or thick-wall profile extrusion.

Advanced Water Circulation and Cooling Systems

Cooling is not just about temperature—it is about control, consistency, and cleanliness.

SWC – Dry Calibrator Water Cycle

Designed for applications requiring controlled cooling without direct water contact, this system manages:

• Water flow rate

• Temperature stability

• Water volume

• Water quality

The result is highly efficient heat extraction with minimal energy loss.

SWC – Wet Calibrator Water Cycle

For high-speed extrusion lines and sensitive profiles, the wet calibration system ensures:

• Uniform surface cooling

• Reduced internal stress

• Minimal risk of shrinkage or warping

Especially critical for PVC window and door profiles, where surface appearance and dimensional stability are non-negotiable.

FBF – Rear Overflow Filter for Wet Calibrators

This specialized filtration system improves water quality directly at the wet calibrator outlet, delivering:

• Exceptional surface finish

• Reduced particle contamination

• Enhanced results for visually sensitive profiles

Ideal for premium architectural PVC profiles.

DWD – Direct Water Drain System

For fast cleaning, maintenance, and scale reduction, the Direct Water Drain (DWD) system allows:

• Rapid and complete water discharge

• Automated cleaning cycles

• Reduced mineral buildup

This ensures long-term system efficiency and minimizes unplanned downtime.
