High-Performance Construction Processing Machinery For Aluminum Profile And Building Material Fabrication

A 1600mm horizontal heated roller press​ designed for the final sealing and curing of flexible spacer (Super Spacer / rubber strip) insulating glass units. After spacer application, glass passes through quartz heating zones (0–300°C) to soften the spacer, then through synchronized upper and lower rubber rollers that apply uniform pressure for a permanent, airtight bond — no bubbles, no gaps, no rework.

The Automatic Glass Cutting Machine is a high-precision CNC cutting system engineered for flat glass processing. Equipped with a servo-driven gantry, automatic loading table, and intelligent nesting software, it delivers fast, accurate cutting for float glass, tempered glass (pre-cut), laminated glass, and mirror. The machine supports cutting lengths up to 6000mm and widths up to 3300mm, with cutting accuracy of ±0.15mm and repeatability of ±0.10mm. Features include automatic air-float positioning, oil-free linear guides, and a user-friendly touchscreen interface compatible with DXF, NC, and CNC file formats. Ideal for architectural glass, furniture glass, automotive glass, and solar panel production lines. CE certification and OEM customization available.

This premium PVC corner cleaning machine is engineered for precision removal of welding seams and flash from UPVC window corners. Built with high-rigidity steel construction and CNC-controlled positioning, it delivers consistent, burr-free cleaning on all four sides of the profile corner in a single cycle. Designed for window and door manufacturers who demand clean aesthetics and high throughput, the machine accommodates various profile geometries and supports both automatic and semi-automatic operation modes. With its user-friendly interface, quick-change cutter system, and minimal maintenance requirements, it's a reliable upgrade for any PVC window production line.

The 450mm CNC Double Head Internal Swing Precision Cutting Saw (45°/90°) is a high-end profile cutting machine designed for aluminum, thermal-break aluminum, and UPVC/PVC window and door production. Equipped with two synchronized Ø450mm TCT carbide blades and CNC-controlled inward-swing saw heads, it performs simultaneous two-end mitre cutting at 45° and 90° with repeat accuracy up to ±0.1mm. The machine features pneumatic auto-feed with adjustable damping, horizontal and vertical pneumatic clamping, and CNC digital positioning for cutting lengths up to 3700mm. The internal swing head design saves floor space while ensuring stable, vibration-free operation. Built for batch production, it delivers burr-free, square ends ready for assembly. CE certification and voltage customization (220V/380V/415V) available for global markets.

The 400mm Double Head Cutting Saw is a professional profile cutting machine engineered for PVC, UPVC, and vinyl window and door production. Equipped with two synchronized carbide-tipped saw blades (Ø400mm), it performs simultaneous two-end cutting at 45° and 90°, delivering burr-free, melt-free ends with repeat accuracy up to ±0.3mm. The machine features pneumatic auto-feed with adjustable damping, horizontal and vertical pneumatic clamping, and a movable head with digital length positioning (450–3500mm range). Designed for batch processing, it cuts window frames, sashes, mullions, and transoms in a single pass, significantly improving production efficiency. Built with a welded steel frame and precision linear guides, it offers low-vibration, long-service operation. CE certification and voltage customization (220V/380V/415V) are available for global markets.

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.
