aluminum profile cutting machine

Model LZJ-100/3500 is a robust hydraulic corner crimper designed for aluminum profile processing. It supports a maximum crimping height of 100mm​ and accommodates frames up to 3500×3500mm. With its pneumatic clamping and hydraulic synchronization system, this machine guarantees consistent crimping quality and structural integrity, making it an ideal choice for manufacturers handling oversized or thick-walled aluminum profiles.

Our Lebulang brand Semi-automatic Double Head Mitre Saw Aluminum Profile Cutting Machine is a cost-effective, high-efficiency solution for cutting aluminum profiles in window, door, and curtain wall manufacturing. Designed for 45° and 90° angle cuts, it features two synchronized cutting heads, pneumatic clamping, and digital length display—delivering precision and stability for small-to-medium batch production.we are one China manufacturer for or so 19 years.

This dual-head seamless welding machine is a core fabrication unit for high-end uPVC, PVC, and vinyl window and door production. Two synchronized welding heads (left fixed, right movable with pneumatic brake) complete 90° and V-shaped corner joints in one cycle, delivering a 0.2 mm invisible seam without upper/lower welding beads—eliminating most manual corner cleaning for both white and color-foil / co-extruded profiles.

This combined uPVC window fabrication set pairs a three-head 45°/90° precision cutting saw with a three-head seamless welding machine, delivering a streamlined workflow from profile cutting to invisible corner joining. The saw unit performs synchronized miter and straight cuts on uPVC/PVC and aluminum profiles; the welder executes 0.2 mm bead-free seams on white, color-laminated, co-extruded, and spray-finished profiles, cleaning top and bottom flash in one cycle.

Designed for demanding industrial environments, this CNC circular saw delivers robust, high-accuracy cutting for large aluminum profiles and extrusions. Its heavy-duty frame, advanced CNC control, and optimized cooling system ensure long-term reliability and superior cut quality for high-volume production.
