China Pneumatic clamping system Manufacturer, Supplier, Factory

This heavy-duty single head corner combining machine is engineered for high-precision aluminum window and door fabrication. Featuring a 100mm crimping stroke and a 3500mm maximum frame capacity, it utilizes synchronized hydraulic feeding and pneumatic clamping to ensure seamless joints with accuracy within 0.15mm. Designed for durability and efficiency, it is the ideal solution for mass production of aluminum profiles.

CNC Aluminum PVC Profile Bending Machine is a 3-axis servo/hydraulic driven rolling bender designed for cold bending aluminum, PVC, UPVC, and thermal break profiles. It delivers high precision, consistent repeatability, and one-pass forming for complex arcs and shapes—widely used in window, door, curtain wall amd so on, and architectural metalwork production lines.Lebulang brand is window and door machine facotry

Shandong Lebulang Precision Machinery Co., Ltd. presents the 1600mm Stainless Steel Insulated Glass Washing and Drying Machine – a high-performance industrial glass cleaning solution engineered for insulating glass production lines. Built with anti‑rust 304 stainless steel, it integrates 4 brush rollers, 3 sponge rollers, and a powerful air knife drying system to deliver spotless, streak‑free glass surfaces. Ideal for architectural glass, float glass, and insulated glass processing. Key purchasing advantages: robust durability, energy‑efficient operation, low maintenance, customizable voltage, fast delivery, and reliable after‑sales support.

Designed for precision and reliability, this 2-meter vertical IG washer dryer delivers crystal-clear glass cleaning for insulating glass production. The machine combines three pairs of soft brushes, a stainless steel washing chamber, and an intelligent temperature-controlled drying system. Compatible with Low-E and tempered glass, it integrates seamlessly into any automatic insulating glass line.

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.

Engineered for high-throughput architectural aluminum fabrication, this 4-meter CNC machining center is built to handle long-span profiles with uncompromising precision. Unlike standard short-bed machines, it processes full-length window, door, and curtain wall profiles in a single cycle—eliminating mid-profile repositioning and ensuring perfect linear accuracy. Equipped with a high-speed electrospindle, automatic tool changer (ATC), and servo-driven clamping system, it seamlessly executes drilling, tapping, milling, and slotting operations with ±0.1mm accuracy. Designed for manufacturers who demand both volume and versatility, it drastically reduces labor costs, minimizes material handling, and guarantees consistent quality across every meter of the profile
