Description

Versatile Multi-Angle Welding

Featuring a highly flexible dual-head design, the machine easily accommodates standard 90° corners as well as arbitrary angles. This makes it the perfect solution for fabricating complex architectural designs, including arch windows, bay windows, and other irregular geometric frames.

Smart PC Control System

Driven by an intuitive PC controller and robust pneumatic transmission, it ensures a highly stable and repeatable welding cycle. Operators can easily manage exact heating times and pressures, guaranteeing consistent, high-strength joints for every UPVC profile.

Oil-Free Precision Bearings

The moving mechanisms utilize premium CM oil-free lubricating bearings and linear ball bearings. This ensures ultra-smooth carriage travel and pinpoint accuracy during the melting and joining phases, guaranteeing flawlessly aligned window corners.

Independent & Low-Maintenance Operation

Capable of completing the entire UPVC welding process independently, its optimized mechanical structure drastically reduces daily wear and tear. The oil-free design keeps the equipment clean and significantly lowers your factory’s routine maintenance costs.

Advantages &Features

01

The versatile processing range allows your factory to easily switch between standard casement windows and complex, custom-shaped UPVC frames without buying extra equipment.

02

By utilizing advanced CM oil-free bearings, the machine maintains long-term mechanical precision without requiring messy and time-consuming daily manual lubrication.

03

The robust pneumatic transmission system ensures stable profile clamping, completely preventing material shifting and delivering exceptionally flat, strong weld seams.

04

An intuitive PC control interface drastically lowers the operator learning curve, allowing standard factory workers to achieve perfect welds with minimal training.

05

High-grade linear motion ball bearings guarantee smooth machine head movement, completely eliminating the jerky motions that often cause misaligned or weak corners.

06

Its independent dual-head operation offers the perfect balance of high production capacity and cost-effective investment for growing window manufacturing facilities.

FAQ

Can this machine weld custom arch windows, or is it only for standard 90-degree corners?

It is highly versatile. One of the machine heads is specially designed with a variable angle function (typically 30° to 180°), allowing you to easily clamp and weld arch windows, bay windows, and other irregular architectural shapes.

What does the “CM oil-free lubricating bearing” mean for my daily maintenance?

It means the machine’s moving parts do not require constant manual oiling. This keeps the internal mechanics clean from dust buildup, prevents oil stains from ruining your white UPVC profiles, and saves your operators valuable maintenance time.

Can it process extra-long UPVC profiles for large patio doors?

Yes. The right welding head is easily movable along the high-precision linear guides, allowing the equipment to accommodate a wide range of profile lengths to easily fabricate oversized doors and commercial windows.

Is the PC control system complicated for entry-level workers to learn?

Not at all. The interface is designed for simplicity. Operators only need to input basic parameters like heating time and welding pressure based on the specific profile thickness, and the machine automatically executes the entire cycle flawlessly.

How does the equipment ensure the welded corners are strong enough?

The combination of exact temperature control via the PC and the highly stable pneumatic clamping ensures the UPVC material melts and fuses evenly. This creates a high-strength, weather-resistant bond that meets strict industry standards.

Will the machine head movement cause the profiles to misalign during the melting phase?

No. The moving carriage utilizes premium linear motion ball bearings that ensure absolute smooth and rigid travel. Once clamped pneumatically, the profiles are held in perfect alignment throughout the entire heating and joining process.
