Description

Variable Angle Corner Welding

The machine enables flexible welding of UPVC profiles at angles between 30° and 180°, making it suitable for arched, special-shape, and non-standard window and door structures without additional fixtures.

Digital Temperature and Time Control

Equipped with an accurate temperature control system, the heating plate maintains stable welding temperatures, while adjustable welding and cooling times ensure uniform fusion and reliable weld quality across different UPVC profile types.

Pneumatic Clamping and Stable Positioning

A pneumatic clamping system applies even pressure during welding, minimizing profile displacement and ensuring precise corner alignment, which directly improves dimensional accuracy and weld seam consistency.

Simple Operation and Fast Changeover

The user-friendly control panel allows quick parameter adjustment and rapid profile changeover, reducing setup time and making the machine suitable for both small-batch customized production and continuous daily operation.

FAQ

What profiles can the Single Head Variable Angle UPVC Welding Machine process?

It is designed exclusively for PVC and UPVC window and door profiles. It is not suitable for aluminum or other metal materials.

What range of angles can this machine weld?

The machine is specifically designed for versatility, easily adjusting to weld any angle between 30° and 180°. This makes it the perfect tool for manufacturing arched, triangular, trapezoidal, and bay window frames.

Will the single-head welding process result in weaker corners?

Not at all. Because it utilizes the same heavy-duty pneumatic clamping and precision heating mechanisms found in our larger machines, it guarantees a deep, uniform melt that meets the highest structural strength standards.

Is the machine suitable for small-batch or customized production?

Yes. Its fast setup, adjustable parameters, and flexible angle control make it ideal for customized orders and mixed-model production.

How is welding strength ensured at variable angles?

Uniform pneumatic clamping and precise temperature control maintain consistent fusion quality, ensuring reliable weld strength regardless of angle settings.

Does it require a lot of factory floor space?

No, its compact vertical design integrating the machine head, control cabinet, and frame minimizes its footprint. It is easily installed in smaller workshops or alongside larger production lines as a dedicated custom-shape station.
