It supports mass production of insulated glass for doors & windows, Low-E insulated glass for curtain walls, and energy-saving passive building glass.
This article sorts out a 100% complete equipment list for new plants, covering all core machines we supply: automatic glass loading table, vertical insulated glass production line, spacer bending machine, molecular sieve filling machine, butyl extruder, automatic sealing robot, vertical film removing machine, vertical laminator, glass lifting crane, automatic unloading system.
I. Complete Standard Equipment List
The full solution follows the standard double-sealing process for insulated glass: spacer forming → molecular sieve filling → glass loading & cleaning → combining & pressing → secondary robot sealing → finished glass unloading. All machines can be seamlessly linked to the vertical production line.
1. Glass Loading & Unloading System
Core equipment: Automatic Loading Table + Automatic Unloading Table
Serving as the start and end of the whole line, the automatic loading table adopts air flotation conveying and intelligent positioning sensors. It can automatically identify glass dimensions, lift sheets and convey in alignment, replacing manual handling to prevent glass scratches and edge chipping. It fits 3–18mm tempered glass, Low-E coated glass, laminated glass and other raw glass types. Matched with a dedicated automatic unloading table, finished glass can be discharged and buffered automatically without manual operation, perfectly matching the high-speed rhythm of vertical lines and greatly improving overall automation.
Optional auxiliary machine: Glass lifting crane. For oversized, heavy curtain wall glass, it assists precise feeding, eliminates breakage risks and improves safety when processing large-size glass.
2. Core Main Equipment: Vertical Fully Automatic Insulated Glass Production Line
The central hub of the whole factory setup, integrating automatic washing, hot air drying, automatic sheet combining, plate pressing and conveying functions. Compared with traditional horizontal lines, vertical design occupies less floor space and processes standard clear glass, Low-E coated glass and extra-large curtain wall glass.
Equipped with high-pressure soft brush washing system and constant-temperature hot air drying unit, it thoroughly removes dust, stains and watermarks from glass surfaces to eliminate fogging and air leakage risks of insulated glass. Servo variable speed control ensures high-precision and even pressing force during sheet combining, guaranteeing air tightness and flatness of finished units — the key equipment to stabilize product quality.
3. Full Set of Aluminum Spacer Processing Equipment
Mandatory supporting machines for primary sealing of insulated glass, determining spacer forming precision and initial sealing performance. Two indispensable machines are required.
(1) CNC Automatic Spacer Bending Machine
Numerically controlled fully automatic unit for one-time bending of square, rectangular and special-shaped aluminum spacers, without secondary manual cutting and splicing. Ultra-small bending tolerance avoids air leakage caused by excessive gaps between spacer joints. Compatible with various standard-width aluminum spacers and warm-edge spacers, featuring fast forming speed and low material loss, suitable for mass production in small, medium and large factories.
(2) Automatic Molecular Sieve Filling Machine
Specially designed to fill desiccant into pre-bent spacers with automatic quantitative filling and hole sealing in fully enclosed operation. It prevents molecular sieve from absorbing moisture and losing efficacy due to air exposure. Solves common manual filling defects such as uneven dosage and loose hole sealing. Effectively maintains dehumidification performance of insulated glass, prevents condensation and fogging, and extends service life drastically.
4. Core Sealing Process Equipment
Air tightness, water tightness and service life of insulated glass fully rely on double-sealing technology. Two core machines work together to realize standardized sealing procedures.
(1) Butyl Extruder – Primary Sealing
Core equipment for basic edge sealing, evenly coating butyl adhesive on both sides of aluminum spacers. Built-in precision temperature control system adjusts glue output temperature according to ambient conditions to avoid stringing at high temperature, glue breakage at low temperature and uneven coating. Continuous, flawless glue layer blocks water vapor penetration, serving as the fundamental anti-leakage and anti-mold barrier for insulated glass, compatible with both standard aluminum spacers and warm-edge spacers.
(2) Vertical Two-component Automatic Sealing Robot – Secondary Structural Sealing
Standard configuration for high-end insulated glass factories to replace manual gluing. Built-in intelligent path recognition system automatically adapts to all sizes and special-shaped insulated glass panels, completing uniform four-side gluing with smooth arc transitions. The glue layer is full, bubble-free and continuous. Compared with manual work, it reduces defective rate by 90% and cuts labor costs significantly. Fully cured structural adhesive features high toughness and strong adhesion, meeting strict supply standards for high-rise buildings and curtain wall projects.
5. Finished Product Finishing & Protection Equipment
(1) Vertical Automatic Film Removing Machine
Customized for Low-E coated insulated glass. Automatically removes edge coating layers to prevent coating oxidation, poor adhesion of sealant, later glue peeling, air leakage and delamination. Vertical fully automatic operation leaves no scratches on glass substrates and supports linkage with high-speed production lines — a must-have machine for Low-E glass processing.
(2) Vertical Automatic Laminator
End-of-line protection equipment for fully sealed insulated glass. It attaches protective film smoothly without bubbles, effectively preventing scratches, abrasion and stains during handling, stacking, transportation and installation. Greatly reduces breakage complaints after delivery and improves finished appearance to boost customer satisfaction.
II. Standard Production Workflow (Linked Sequence of All Full-set Machines)
- Raw glass feeding: Automatic loading table conveys raw glass
- Spacer pre-processing: Aluminum spacer bending → automatic molecular sieve filling & hole sealing → butyl coating to finish primary sealing
- Glass finishing: Vertical line washing & drying → automatic coating removal for Low-E glass
- Sheet combining: Precise alignment, spacer installation and plate pressing forming
- Structural sealing: Automatic four-side gluing by sealing robot for secondary structural sealing
- Finished protection: Automatic film lamination → automatic unloading, stacking and storage
III. Basic Factory Setup Requirements (For New Beginners)
- Environment: Closed, dry and dust-free workshop. Humid surroundings will cause molecular sieve moisture absorption, butyl adhesive failure and glass fogging.
- Power Supply: Stable industrial power supply to support continuous mass production.
- Labor Arrangement: Only 2–3 operators needed for full-automatic complete line, no large team of skilled workers required to cut labor expenditure.
IV. Key Purchase Tips to Avoid Pitfalls
- Closed workflow is mandatory: Never rely on manual labor to compensate missing machines. Lack of film remover, laminator or automatic filling equipment will directly lead to high defective rates and inability to accept high-end orders.
- Linked & compatible equipment recommended: Prioritize matched vertical complete sets from the same brand to avoid mismatched parameters, line jams and poor connection between different brands.
- Distinguish essential standard & optional upgraded configurations: Factories focusing on engineering mass orders must equip sealing robots and automatic molecular sieve fillers. Start-up small plants can prioritize core sealing machines and purchase auxiliary units as needed.
- Match equipment to product positioning: Factories producing Low-E and curtain wall glass must install vertical film removing machines. Export-oriented production requires CE-standard configurations to meet compliance standards for overseas orders.
