PVC WINDOW CORNER CLEANING MACHINE

PVC Window Corner Cleaning Machine – The Key to Perfect Quality in Window Manufacturing

Introduction

In PVC window manufacturing, welding is crucial for stability and sealing. However, after welding, weld seams and excess material remain on the corners, which can affect both the appearance and functionality of the window. This is where the PVC window corner cleaning machine comes into play.

It ensures smooth, clean, and precise corners, improves overall product quality, and significantly reduces manual labor. For any modern production line, it is an essential element.

What Is a PVC Window Corner Cleaning Machine?

A corner cleaning machine is a specialized CNC or semi-automatic system designed to remove weld seams from PVC and uPVC window profiles after welding.

Key Functions:

• Automatic removal of weld excess from frames and sashes

• CNC-controlled tools for precision machining

• Customizable programs for different profile designs

• Smooth surfaces without manual finishing

• Can be integrated with welding machines in production lines

Workflow with a Corner Cleaning Machine

1. Clamping
   The welded window profile is fixed securely in the machine.

2. Scanning and Detection
   Sensors or CNC software identify the position of the weld seam.

3. Corner Cleaning
   Milling cutters, blades, and grinders remove excess PVC material.

4. Fine Finishing
   Corners and edges are polished until they are perfectly smooth.

5. Completion
   The profile exits the machine with visually flawless and functional corners.
