Key Selling Points / Features
1.Jumbo Size Capacity (2500×4000mm): Built for large architectural glass and commercial double glazing projects, supporting glass thickness from 3mm to 15mm and total IG thickness up to 75mm.
2.Inline Argon Gas Filling (Over 85%+ Efficiency): Integrated pressing and gas-filling section ensures uniform gas distribution, reducing thermal conductivity and meeting international energy-saving standards.
3.Low-E Glass Coating Detection: Equipped with high-precision sensors that automatically identify Soft/Hard coated Low-E glass to prevent surface damage during washing and pressing.
4.Heavy-Duty Structural Frame: Constructed with 5mm thick, 100x100mm and 80x80mm high-strength steel tubes to eliminate vibration and ensure long-term mechanical stability.
5.High-Cleanliness Washing System: Features 4 pairs of high-density soft brushes and 2 pairs of stainless-steel air knives powered by a high-pressure blower for streak-free drying.
6.Siemens Industrial Control System: Uses premium SIEMENS PLC and touchscreen interface with multi-language support for precise transmission speed (0–50 m/min) and fault diagnosis.

Workstation Process & Workflow
Section 1: Glass Loading & Soft-Coated Low-E Detection01
Smooth glass feeding with automatic detection for Soft/Hard Low-E coated glass to ensure correct processing orientation.
Section 2: High-Pressure Washing & Drying02
4 pairs of soft brushes combined with warm water washing. 2 pairs of air knives with a soundproof blower ensure 100% clean and dry glass surfaces before assembly.
Section 3: High-Brightness LED Inspection Section03
Built-in LED light box allows operators to easily inspect glass for dust, scratches, or imperfections before spacer frame placement.
Section 4: Aluminum Spacer Frame Positioning04
Precise positioning system enables fast and accurate manual or automatic alignment of aluminum spacer bars with butyl sealant.
Section 5: Automated Pressing & Inline Argon Gas Filling05
Servomotor-driven press plate ensures accurate press pressure without glass breakage. Argon gas is filled synchronously inside the chamber during pressing.
Section 6: Output & Tilting Discharge Conveyor06
Smooth glass transport section equipped with motor drives, ready for automatic or manual secondary sealant application (silicone or polysulfide).

Heavy‑Duty Welded Machine Frame
Built with 5 mm thick steel tubes of 100×100 mm and 80×80 mm specifications. High structural rigidity to guarantee long‑term stable operation under heavy‑load large‑size glass productioncaremachin....

Durable Conveying System
Reinforced conveyor wheels and bearings ensure smooth glass transportation, reduce wear and lower failure rate for long‑time continuous running.

High‑Efficiency Washing & Drying Unit
Equipped with 4 pairs of washing brushes and 2 pairs of air knives. Realize thorough glass surface cleaning and spot‑free drying, well‑suited for clear glass and Low‑E glass substrates.

Industrial Aluminum Profile Modular Sections
The 3rd, 4th and 5th working sections adopt premium industrial aluminum profiles. Modular structure benefits assembly, alignment and daily maintenance.
