China Double Head Seamless Welder Manufacturer, Supplier, Factory

As a professional insulated glass machinery manufacturer, Lebulang supports global buyers to inquire, wholesale and customize the 2000 Horizontal Insulated Glass Line with Washing Drying Assembly. This full-automatic horizontal integrated production line integrates glass washing, drying, conveying, spacer assembly and laminating procedures. Adopting low-noise horizontal transmission structure, it features stable operation, uniform cleaning effect and low operational failure rate. Ideal for small and medium-sized glass processing factories for standard insulated glass mass production. We provide complete certification documents, factory inspection service and one-stop after-sales guarantee for all overseas clients.

Purpose-engineered for high-volume architectural aluminum fabrication, this 4-meter CNC machining center redefines efficiency in long-profile processing. Unlike conventional short-bed machines that rely on repeated repositioning, it executes full-length drilling, tapping, milling, and slotting in a single cycle—eliminating cumulative errors and guaranteeing flawless linear accuracy across every meter. Powered by a high-speed electrospindle, a seamless automatic tool changer (ATC), and servo-driven clamping, it delivers ±0.1mm precision with industrial-grade repeatability. Designed for manufacturers who refuse to compromise between throughput and quality, it slashes labor dependency, minimizes material handling, and provides the ultimate scalable solution for system windows, premium façades, and curtain wall systems.

Unlike single-motor systems, this dual-motor thermal break machine gives you independent control over knurling and strip insertion heads. Each motor drives its own process—precision tooth-rolling on the profile groove, followed by accurate PA66 strip feeding—ensuring perfect synchronization without compromise. CNC-adjustable head positions, pneumatic clamping, and heavy-duty construction make it the go-to solution for high-volume thermal break aluminum production lines.

The Arbitrary Angle Welding Machine for PVC Windows is a professional semi-automatic welding equipment specially developed for PVC and UPVC door and window profile processing. Adopting mature mechanical control technology without CNC setting, this machine supports flexible arbitrary angle welding from 30° to 180°, perfectly solving the processing difficulty of special-shaped and arc window frames that conventional 90° welding machines cannot handle. With a 160mm maximum welded profile width and stable 380V operation, it features simple structure, convenient angle adjustment and reliable welding quality. We supply matching auxiliary accessories and accept customized machine layouts, which brings great procurement convenience for local wholesalers.

Shandong Lebulang Precision Machinery Co., Ltd. developed the 1200 Horizontal Insulated Glass Washing and Drying Machine, a compact high-precision device dedicated to modern insulated glass production. Adopting a humanized horizontal feeding structure, it avoids glass breakage and operator fatigue caused by vertical lifting. Equipped with multi-stage cleaning, circulating hot air and high-pressure air knife drying systems, it delivers 100% spot-free, static-free glass surfaces. With optional soft brushes for Low-E coated glass, it is ideal equipment for high-standard IG manufacturing.

This 550 CNC outward swing precision cutting saw is designed for high-accuracy 45° mitre and 90° square cutting of aluminum profiles, thermal break aluminum windows, and UPVC/PVC profiles. The saw head swings outward for safe, easy operation and material loading. Equipped with a Ø550 mm carbide blade, CNC control, and pneumatic clamping, it delivers clean, burr-free cuts with excellent repeatability. Available in single-head and double-head configurations.
