PVC UPVC Colorful Windows Profile Seamless Welding Machines with 4 Heads is premium welding equipment tailored for colorful, co extruded and sprayed PVC/UPVC door & window profiles. Unlike conventional welders, it eliminates traditional welding burrs via integrated seamless welding and automatic cleaning. It effectively avoids profile discoloration, glue overflow and visible seams, upgrading finished windows’ aesthetics and sealing performance. Equipped with reliable pneumatic and PLC control systems, it enables multi station simultaneous operation, serving as ideal core machinery for high volume, high quality PVC door and window manufacturing.

The CNC Glass Window Sealant Spreading Machinery is dual-station cantilever automatic gluing gear for doors, windows, curtain walls and signboards. It auto detects glass height and frame size to complete full-automatic gluing without skilled workers. Layered gluing, cyclic stations and anti-curing structure ensure even, tight and neat seal lines. Working with bulk single-component silicone glue, it cuts glue cost with steady high output. Supplied with full wearing parts and one-year warranty, this machine is a top pick for overseas importers running standardized window production lines.

If you are sourcing high-efficiency, fully automatic glass processing equipment for insulated and tempered glass mass production, our Lebulang 2000 Vertical CNC Washing Drying Press Line for Insulated and Tempered Glass Machine is the perfect industrial solution for your glass deep processing factory. This all-in-one vertical production line integrates automatic washing, constant-temperature drying and precision pressing functions, eliminating the need for separate standalone machines. Ideal for bulk order production, commercial glass manufacturing and factory upgrading, it helps buyers reduce labor input, save workshop space, stabilize finished glass quality and greatly improve overall production efficiency, serving as a cost-effective core equipment for medium and large glass processing enterprises.

Multi-Angle 3+2 Axis CNC End Miller is engineered for complex, non-standard aluminum mullions, transoms, and frame profiles—especially thermal break, system window, and curtain wall aluminum sections. Combining 3 linear servo axes (X/Y/Z) + 2 rotary axes (spindle tilt + flip), Multi-Angle 3+2 End Miller for Special Shape Aluminum Mullion delivers true multi-angle ( 45° to +45°), one-setup milling for special shapes that standard 3+1 machines cannot handle. Lebulang Lebulang brand is one china machine manufacturer in china . Dual Cut 4+2 Axis End Miller Thermal Break Aluminium Production Line

Innovation meets versatility in the Lebulang PVC End Milling Machine for Window Profiles. Designed for semi-automatic end-face milling of PVC and aluminum-plastic window profiles, it supports a wide range of structures using different tools – from step surfaces and rectangular grooves to tenons. The worktable positioning plate can be adjusted from -55° to +55°, enabling precise bevel cutting at various angles. Thanks to a linear bearing motion pair for tool feed, the machine delivers stable performance with an end-face surface roughness of Ra12.5μm. A reliable asset for medium-to-large-scale manufacturing.

Purpose-built for architectural aluminum and façade manufacturers, this advanced 3+2 axis CNC end miller solves the industry’s toughest challenge: machining complex, irregular mullion profiles with absolute precision. By combining three linear CNC axes with a tilting spindle, it performs multi-angle end milling, step-face machining, and chamfering in a single setup—eliminating cumulative errors and ensuring seamless, gap-free assembly in system windows and curtain walls. With servo-driven accuracy (±0.1mm), automatic tool setting, and multi-profile program storage, it reduces labor dependency, minimizes scrap, and accelerates changeovers, making it the definitive solution for both high-mix custom projects and high-volume production.
