Standard Corner Cleaning Machine QJ03-120

Product Overview

The standard corner cleaning machine (model QJ03-120) is an indispensable specialized processing equipment in the production process of PVC-U windows and doors. Its core function is to remove weld beads and weld seams generated after welding. By precisely treating the corners of windows and doors, this equipment ensures that the corners are smooth and aesthetically pleasing, while also providing a solid foundation for subsequent glass installation and sealing strip application. It is one of the key devices for guaranteeing the quality of finished PVC-U window and door products. The machine features dedicated processing structures designed for the upper and lower surfaces of the corner joints as well as the outer corner faces, enabling precise removal of protrusions at weld seams on the profile surface and fine adjustment of weld seams on the outer corners of the frame, thereby comprehensively optimizing the machining accuracy of the window and door corners.

Core Functions and Processing Scope

1. Upper and Lower Surface Treatment of Corner Joints: Precisely removes protruding parts at weld seams on the surface of PVC-U window and door profiles, restoring the surface to smoothness and preventing protrusions from affecting the fit between glass and sealing strips, thus ensuring both the sealing performance and aesthetic appeal of the windows and doors.
2. Outer Corner Face Finishing: Provides meticulous finishing of weld seams on the outer corners of the frame, eliminating irregular welds left after welding, resulting in smooth, well-defined outer corner lines that enhance the overall visual texture of the windows and doors, meeting the appearance standards of high-quality products.
