4 HEAD WELDING MACHINE FOR PVC PLASTIC PROFILES EVOO IV

4-Head Welding Machine for PVC Plastic Profiles EVOO IV – Four Corners, One Perfect Connection

Technological Precision for Modern Window and Door Manufacturing

EVOO IV – Advanced Welding Technology for Industrial PVC Frame Production

The 4-Head Welding Machine for PVC Plastic Profiles EVOO IV by Evomatec represents the latest generation of industrial welding systems for the manufacturing of PVC window frames, door frames, and sashes.
This four-head PVC welding machine combines digital temperature control, energy-efficient heating systems, and fully automatic process management — all engineered for maximum precision, speed, and durability in serial production.

With its automatic heating and cooling cycle, the machine welds all four frame corners simultaneously in a single operation. The result is uniform, airtight, and high-strength connections across all PVC and plastic profile types — making it the ideal solution for window, door, and uPVC fabrication.

Functionality – Four Heads for Perfect Frame Welding

A 4-head welding machine for PVC windows operates on the principle of simultaneous corner welding. All four profile ends are heated, pressed, and cooled at the same time.
Through digital process control, the system ensures even temperature distribution and controlled pressing pressure, minimizing burr formation, distortion, and energy consumption.

The machine can handle a wide range of profile geometries — from classic PVC window frames to modern door systems. Whether in window manufacturing, door construction, or industrial profile fabrication, the EVOO IV consistently delivers reproducible, high-quality results.

Technical Data and Performance Features

The 4-Head Welding Machine for Plastic Profiles EVOO IV is built to European CE standards, suitable for both small workshops and fully automated production lines.

Technical Specifications

Frame size (min./max.): 350 × 410 mm / 2650 × 4110 mm
Profile height: 40 – 200 mm
Profile width: 30 – 150 mm
Welding angle: 60° – 180°
Weld seam: approx. 0.2 mm
Power: 14.75 kW
Voltage: 400 V / 3 Ph AC
Air pressure: 6 – 8 bar
Frequency: 50 – 60 Hz

These performance characteristics make the EVOO IV an essential tool for production facilities that demand precision, efficiency, and high output capacity.

Fully Automatic Welding Cycle with Digital Control

The EVOO IV executes a fully automated welding process across four precisely controlled phases:

1. Profile Detection and Positioning

The system automatically detects and clamps the inserted PVC profiles in the correct position.

2. Heating

The digitally controlled heating plate ensures uniform heating of welding surfaces between 0 °C and 350 °C.

3. Welding

All four welding heads press the profile ends together simultaneously, guaranteeing perfect angular accuracy and strong, airtight seams.

4. Cooling and Return

After controlled cooling, the system automatically opens and returns to its starting position — ready for the next cycle.

This digital process automation ensures consistent weld quality and maximum repeatability, independent of the operator.

Structural Advantages of the EVOO IV

The 4-Head Welding Machine for Window Frames features a heavy-duty, low-vibration steel frame with precision-ground linear guides and durable Teflon-coated heating plates.
The pneumatic drive system provides even pressure distribution, uniform seam formation, and minimal wear during continuous operation.
