Product Overview

The CNC Glass Window Sealant Spreading Machinery is engineered for the automated sealing of UPVC and aluminum doors, windows, and curtain walls. Designed to replace manual gluing processes, this equipment utilizes an industrial-grade 10-axis independent control system and a high-end PLC to ensure precise glue output and movement.

Core Product Features

Smart Automatic Operation

Automatically detects glass size and height; no professional technician required -- ordinary workers can operate with ease.

High-efficiency Dual-station Circulation

Supports multi-station cyclic gluing for continuous production; finished products can be moved in whole batches after gluing, preventing profile deformation caused by secondary handling with uncured glue.

Superior Sealing & Zero Stringing

Ensures uniform glue output with neat 45° corner transitions; proprietary program precisely controls speed and glue output to achieve zero stringing at closing positions.

Anti-solidification Design & Cost Savings

Fully sealed pipeline and special sealing cap prevent sealant curing during long-term shutdown; uses 20L/25L bulk silicone, saving over 30% on glue costs.

Intelligent CNC System

Stores 100 gluing formulas, supports remote upgrade and lifelong free program optimization.

Safe, Stable & Versatile

The CNC Glass Window Sealant Spreading Machinery is equipped with self-inspection protection and glue head anti-collision to reduce failures; it supports three-side gluing for louver windows and alternate gluing for sliding windows, adaptable to various window types.

Technical Parameters

Support & Service

Lebulang provides a 2-year professional warranty on the control system, along with lifelong free program optimization and remote upgrade capabilities. The equipment is designed for integration into fully automatic production lines, backed by the manufacturer's established global after-sales service network.

Product Details

Advanced Intelligent Control

Industrial-grade 10-axis independent control system with high-end PLC, offering strong scalability and stable operation. Comes with 2-year professional warranty, supports customized program development and automatic line integration.

Effective Anti-stringing Performance

Self-developed algorithm precisely adjusts speed, glue output and stop-glue distance to thoroughly eliminate glue stringing, ensuring smooth and neat glue lines.

Long-term Anti-solidification Design

Fully sealed glue delivery pipeline keeps single-component silicone glue from solidifying for 5--7 months; glue head equipped with sealing cap and special silicone oil for dual protection.

High-efficiency Production Capacity

Standard gluing speed reaches 7--12 m/min, idle speed up to 30 m/min, and glue replacement takes less than 120 seconds for uninterrupted batch production.

Wide Application Range

Suitable for doors, windows, curtain walls and advertising boards. Max processing size: 3750mm×1250mm (1600mm widened version optional); fits profiles with thickness ≥3mm and assembly gap ≤5mm.

Superior Cost-saving Advantage

Uses 20L/25L bulk single-component neutral silicone sealant, saving over 30% glue usage compared to manual gluing, with bulk glue about 5% cheaper than tubular glue, effectively reducing long-term production costs.

FAQ

Q1: What kind of products is this CNC Glass Window Sealant Spreading Machinery suitable for?

A1: It is specially used for automatic sealant spreading and sealing of UPVC/aluminum doors, windows, curtain walls and advertising boards. It supports three-side gluing for louver window sashes and alternate gluing for sliding windows.

Q2: Does the equipment need professional glue workers to operate?

A2: No. The machine realizes automatic glass size and height induction. Ordinary workers can complete standard gluing work after simple training, effectively saving skilled labor cost.

Q3: How to solve the problem of glue stringing during gluing?

A3: Adopting independently developed program algorithm, the machine precisely controls walking speed, glue output and stop distance at the end of gluing, completely eliminating glue stringing and ensuring smooth and neat glue lines.

Q4: Will the sealant solidify if the machine stops for a long time?

A4: The fully sealed glue delivery pipeline can prevent sealant solidification for 5-7 months. The glue head is equipped with a special sealing cap and silicone oil protection, which effectively avoids glue solidification during holiday shutdown.

Q5: What are the advantages of the CNC control system?

A5: Equipped with a 10-axis independent control system, it can store 100 sets of gluing formulas for quick recall. It supports remote upgrade and lifelong free program optimization, with strong stability and scalability.

Q6: What is the cost advantage of this automatic gluing machine?

A6: It adopts bulk 20L/25L silicone sealant, saving more than 30% glue consumption. Bulk glue is about 5% lower in cost than traditional tubular glue, greatly reducing long-term production costs.

Q7: Can this machine be connected to an automatic production line?

A7: Yes. The CNC Glass Window Sealant Spreading Machinery supports customized docking structure, which can be combined with other window processing machines to form a fully automatic production line.
