FOUR-HEAD WELDING MACHINE EVOO IV


Four-Head Welding Machine EVOO IV – Precision, Efficiency, and Perfection in PVC Window Production

Technological Innovation for Modern PVC Frame Manufacturing

The Four-Head Welding Machine EVOO IV by Evomatec represents a new generation of automated welding systems designed for simultaneous welding of four corners of PVC, uPVC, and plastic profiles.
Developed for the precise production of PVC window frames, door frames, sashes, and mullions, the EVOO IV is a cornerstone of professional PVC manufacturing.

With its fully automatic four-head welding technology, the EVOO IV enables all four corners of a frame to be welded at once – delivering maximum accuracy and consistent quality.
The integrated electronic thermostat control system allows precise temperature adjustment between 0 °C and 350 °C, with programmable welding time, pressure, and cooling cycles to ensure uniform heating and high-quality bonding.

Technical Excellence and Advanced Construction

Combining robust mechanical design with intelligent control software, the EVOO IV ensures consistent results across all frame dimensions – from small window sashes to large PVC frames.
Its electronically regulated heating plate distributes heat evenly across the welding surface, creating a homogeneous and durable bond without deforming the PVC material.

Main Technical Specifications:

  • Frame size with mold: min. 350 × 410 mm

  • Frame size without mold: max. 2650 × 4110 mm

  • Profile height: 40–200 mm

  • Profile width: 30–150 mm

  • Welding bead thickness: 0.2 mm

  • Power: 14.75 kW

  • Voltage: 400 V / 3N PE AC

  • Frequency: 50–60 Hz

  • Air pressure: 6–8 bar

Its solid frame design ensures high stability, easy accessibility to all welding units, and seamless integration into automated production lines.

Functionality and Process Control

The EVOO IV operates via a fully automated welding cycle, precisely coordinating each phase of the process – from clamping to heating, fusing, and cooling:

  1. Automatic Profile Detection and Alignment:
    The system automatically detects and positions the PVC profiles with exact alignment.

  2. Heating Phase:
    The heating plate moves between the profile edges and evenly warms both surfaces for optimal bonding.

  3. Four-Corner Welding:
    All four heads apply synchronized pressure to fuse the profiles simultaneously, producing airtight and watertight joints.

  4. Cooling Phase:
    The heating plate retracts, and the profiles remain clamped to ensure controlled cooling and perfect weld strength.

  5. Automatic Reset:
    After cooling, all heads automatically return to their initial positions – ready for the next cycle.

Ultimate Precision in PVC Welding

The EVOO IV guarantees perfect weld seams with minimal burrs (0.2 mm) – ideal for seamless corner cleaning and finishing operations.
Each weld is strong, airtight, and visually flawless, ensuring premium results that meet the highest European window manufacturing standards.

Its digital process management system allows operators to store, recall, and optimize welding parameters, providing repeatable consistency in mass production.
Moreover, the independent programmability of each welding head allows custom frame designs and non-standard profiles to be processed with ease.

Advantages of the Four-Head Welding Machine EVOO IV

1. Maximum Efficiency Through Four-Side Welding

All four corners are welded simultaneously – reducing production time, labor, and handling, while boosting throughput.

2. Energy Efficiency and Process Stability

The advanced electronic thermostat ensures even temperature distribution and lower energy consumption.

3. Perfect, Smooth Welding Finish

The uniform pressure and precise thermal control guarantee clean, burr-free joints with no deformation.

4. Intuitive Control and Operation

A central operator panel allows easy management of temperature, timing, and cycle programs – ideal for repetitive, high-volume tasks.

5. Durability and Low Maintenance

The machine’s solid construction, Teflon-coated heating surfaces, and industrial-grade components ensure long service life and minimal maintenance.

6. Integration in Automated Production Lines

Fully compatible with CNC systems, barcode management, and digital production software, the EVOO IV fits seamlessly into Industry 4.0 environments.

Applications

The EVOO IV Four-Head Welding Machine is designed for:

  • Window production: Welding of sashes, mullions, and frame corners
