Insulating Glass Production Line Planning & Project Support

SANKEN has been exporting glass-processing machinery since 2002. For insulating glass production projects, we can support customers with equipment configuration, production-line planning, factory layout, equipment manufacturing, pre-shipment inspection, installation, commissioning, operator training and after-sales technical support.

To configure a suitable insulating glass production line, customers can provide the required glass dimensions, glass thickness, IGU structure, spacer type, target production capacity, Low-E processing requirements, factory dimensions and preferred automation level.

At the test site, the technicians started the joint production line. After the original glass was processed by the high-precision edge grinding machine, it was seamlessly connected to the high-pressure air cleaning machine through the intelligent conveyor belt, without any manual intervention.



1.Pioneered positioning mode: Non touch glass after positioning probe switch. Longer life, more convenient operation and maintenance;

2.Patent structure, processing glass thickness 3~12mm;

3.All imported servo electronic, to make the equipment more stable and reliable;

4.Transmission using a toothed chain transmission, more stable, more static;

5.Opening & Closing using rack drive, speed up to 40 meters per minute, more accurate, more durable;

6.Hemline grinding function.



Glass Automatic Four Sides Edger is designed for glass chamfering with features of economy, efficiency and automatic identification of glass size and thickness. This machine is suitable for processing the construction glass, insulating glass of window and door and other different size flat glass with a large quantity. Being connected with other machines, the production efficiency can be improved deeply.



1.Adopt the servo-driven, annular timing belt and rubber roller for conveying and polyurethane wheel for press which ensures the stable glass transmission, accurate positioning and excellent grinding performance.

2.The automatic opening and closing mechanism of grinding motor and lateral pressing wheel are adopted the gear reducer and servo driver. Assembling with the ball screw rod, liner guide rail, pinion and rack, the mechanism can be accuracy.

3.The motor rotation system adopts the gear reducer and servo driver that make it position precisely.

4.Adopt limit switch probe positioning instead of touch glass that avoid the distress of parameters resetting due to the replacement of probe. This novel design greatly improves the life of the limit switch probe and makes the operation and maintenance more convenient.

5.Adopt human interface and PLC control system, easy operate.



Highly intelligent high-speed four-side grinding is widely used in the fine edge grinding of door and window glass. For developed countries, they need it very much, and for developing countries, which do not have high requirements for edge grinding quality, it will also be completely suitable for them. Use seaming machine to grind the edge to achieve the requirements of tempered edge grinding.

The key role and technical advantages of autoclaves in laminated glass production**

Laminated glass (also known as laminated glass) is a safety material widely used in construction, automobiles, photovoltaics and other fields. Its core production process cannot be separated from the key support of autoclaves. Through high temperature and high pressure environment, the autoclave can achieve efficient bonding between glass and interlayers (such as PVB, EVA, SGP, etc.), ensuring that the product has impact resistance, explosion-proof, sound insulation and other characteristics. The following are the specific applications and technical highlights of autoclaves in laminated glass production:

I. The core process of autoclaves in laminated glass production

1. Pre-pressing and exhausting stage

- After the glass and the interlayer are initially overlapped, the air needs to be exhausted through the pre-pressing equipment to prevent bubbles from being generated during the high pressure process.
2. High temperature and high pressure bonding

- The pre-pressed glass is sent into the autoclave, and continuously heated and pressurized for 2-4 hours under **120-150℃, 1.1-1.5MPa** environment to completely melt the interlayer and tightly bond it to the glass.
3. Gradient cooling and shaping

- Slowly cool down through the precise temperature control system to avoid deformation or debonding of the glass due to temperature difference stress.

As the core equipment of the laminated glass industry chain, the technological innovation of the autoclave has directly promoted the breakthrough of downstream product performance and application scenarios. SANKEN will continue to deepen its high-pressure forming field, and enable customers to upgrade their competitiveness in the fields of safety glass, new energy, and smart buildings with more precise pressure control technology, more efficient energy utilization, and more intelligent operation and maintenance system.
