The Importance of PVC Welding Technology in Modern Window Production

PVC (polyvinyl chloride) has long been established as the leading material in window manufacturing. Its dimensional stability, weather resistance, and excellent insulation properties make it the preferred choice for modern profile systems. To ensure durable and precise frame connections, a high-quality welding machine is essential.

The EVOO ISN enables precise thermal welding of PVC profiles at angles between 30° and 180°. It delivers permanently strong joints that withstand mechanical stress while meeting today’s strict energy-efficiency and aesthetic standards.

Technical Design and Operating Principle

The EVOO ISN is a single-head welding machine based on pneumatic motion, electronic temperature control, and automated process logic. It combines industrial robustness with digital precision — ensuring consistent results with minimal operator intervention.

Pneumatic Motion System

The EVOO ISN operates with a fully pneumatic motion control system that maintains constant pressure throughout the welding process. This ensures vibration-free operation and clean, seamless welding results.

Temperature Control

An electronic thermostat allows precise temperature adjustment between 0°C and 350°C. The digital heating control guarantees uniform melting of the PVC surface without overheating or color changes.

Automatic Process Cycle

Once the profiles are positioned, the entire welding cycle — heating, joining, cooling, and release — runs automatically. A single button starts the process, ensuring operator-friendly use and consistent quality.

Adjustable Welding Angles

The adjustable range between 30° and 180° allows processing of all standard frame corners and special designs for doors, facades, and roof windows.

Heating and Control System

The heating plate is Teflon-coated to prevent PVC residue from sticking and to ensure smooth, clean joints throughout continuous production.

Detailed Welding Process

The EVOO ISN performs the PVC welding process in four precisely controlled stages:

1. Profile Positioning
   The profile ends are aligned and pneumatically clamped.

2. Heating Phase
   The Teflon-coated plate heats both contact surfaces evenly to the required melting temperature.

3. Joining Phase
   Once the heating plate retracts, the profile ends are pressed together under controlled pneumatic pressure to form a homogeneous joint.

4. Cooling and Release
   The welded joint cools under pressure to maintain perfect alignment and structural stability.

This automated process guarantees consistent quality and reliable results for every welded frame.
