About Us
Company
Founded in 1996, Shandong Lebulang Precision Machinery Co., Ltd. is a professional high-tech enterprise integrating R&D, production, sales and after-sales service. With nearly 30 years of deep cultivation in the door and window processing machinery industry, we focus on the research and manufacturing of high-precision aluminum alloy, industrial aluminum, curtain wall and insulated glass processing equipment, as well as full-series UPVC plastic steel window machinery. After decades of steady development, we have grown into a well-known industry and trade integrated manufacturer, continuously optimizing core equipment technologies such as thermal break knurling & inserting machines, CNC profile cutting and milling machines, and insulated glass production lines to meet the diverse and high-precision production needs of global customers. Adhering to the development philosophy of "Technological Innovation, Worry-free Service", we keep upgrading product performance and technical parameters to adapt to overseas market standards.
The LBL Butyl Sealant Coating Machine for Insulating Glass is a specialized automated equipment designed for the primary sealing process in insulated glass (IG) manufacturing. It precisely extrudes and applies hot butyl sealant onto aluminum spacers to form the inner seal of double or triple glazing units. This automated equipment produces continuous, uniform butyl beads to sustain IGU structural integrity and moisture resistance. Standout purchaser merits: adjustable output capacity, minimal material consumption, worldwide technical guidance, flexible machine layout and full factory pre-test before shipment.
As a professional insulated glass machinery manufacturer, LBL 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.
Shandong Lebolang Precision Machinery Co., Ltd. presents the 1600 Insulating Glass Hot Press Machine — essential for double/triple insulating glass lines. With a 1600mm max width and intelligent constant temperature control, it integrates heating, air exhausting and laminating for bubble-free, uniform bonding. Stable, energy-saving and CE/ISO compliant, it serves global small and medium-sized glass processors for both mass and custom projects. Distinctive acquirer advantages: expedited factory trial run reservation, cross-region installation crew dispatch and modular structure for later capacity expansion.
Maximize floor space with the 2500 Vertical Insulated Glass Washing and Drying Machine by Shandong Lebulang Precision Machinery Co., Ltd. Designed for large-format glass up to 2500mm, this robust unit features 304 stainless steel construction, Low-E safe brushes, and rapid hot air drying. It guarantees spotless, dry surfaces for perfect sealing. Built for high efficiency, easy maintenance, and fast ROI, it is the ultimate washing solution for modern glass processors.
Our Industrial Aluminum Sawing Machine is a heavy-duty, fully servo CNC automatic cutting solution engineered exclusively for mass processing all types of industrial aluminum extrusions. Integrating servo fixed-length feeding, hydro-pneumatic stable saw cutting, multi-angle mitre machining and intelligent automatic clamping, this all-in-one sawing equipment eliminates manual measuring, repeated clamping and secondary deburring procedures for curtain wall, window door, solar bracket and general industrial aluminum profile manufacturers. With ±0.05mm ultra-high positioning precision and burr-free cutting performance, it supports 24-hour uninterrupted heavy-load production, drastically lifting workshop throughput while lowering aluminum raw material waste and labor expenditure. Our LBL brand high quality hot sale machine models hold CE & ISO9001 certifications to meet import standards for European, Middle Eastern, Southeast Asian, Australian and American industrial buyers.
LBL brand CNC Arbitrary Angle Mitre Saw for Aluminum Profile Cutting is a high-precision, servo-driven industrial cutting machine designed for unlimited angle cutting of aluminum, PVC, and non-ferrous profiles. Ideal for window, door, curtain wall, and architectural aluminum fabrication, it features 22.5° to 157.5° continuous auto-angle adjustment (far beyond standard 45°/90° saws) and delivers burr-free, ±0.1mm repeat accuracy cuts.we are one manufacture for good price.
