Four Head Welding Machine - PVC Window Angle Frame Welding Equipment is a high-precision professional device for UPVC, PVC and plastic steel door and window frame processing. Four Head Welding Machine PVC Window Frame Welding Equipment supports dual working modes of independent single-head operation and four-head linkage synchronous work, realizing one-step forming for standard rectangular frames and various special-shaped window frames to meet diverse production needs. Equipped with advanced seamless welding technology, accurate pneumatic clamping and stable PLC intelligent control system, the machine fits ordinary PVC profiles, co-extruded colored profiles and film-coated profiles perfectly. With flexible batch customization, pre-job machine debugging service and stable operational performance, it lowers production thresholds and brings reliable long-term returns for profile processing manufacturers.

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

Heavy Duty Curtain Wall Notching Saw is a professional heavy-duty cutting machine engineered exclusively for aluminum curtain wall, skylight, and facade profile end notching, angle cutting, and joint processing. It adopts a dual-saw-blade synchronous cutting design, integrating ±45° arbitrary angle cutting, end notching, and groove milling in one machine. With a heavy-duty cast iron body and high-precision linear guide motion system, it delivers stable performance and high efficiency for mass production of mullions, transoms, and connection brackets in unitized and stick curtain walls.Our Lebulang Brand is China Manufacturer.

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.

This 4000 CNC drilling & milling machine is specially designed for processing thermal break aluminum and UPVC window & door profiles. It handles lock slots, water drain holes, hardware holes, and end milling with high precision. With a 4000 mm working length, it also suits general industrial aluminum extrusion and curtain wall profile machining. Available in single-spindle​ and double-head dual-motor​ configurations to match different production volumes
