Glass toughening machine

Types of Glass Toughening Machines

A glass toughening machine refers to a machine that is used to strengthen glass through the application of heat. The glass is heated to approximately 620-670 degrees Celsius and then rapidly cooled (tempered). This process changes the molecular structure of the glass so that it is stronger and more durable. Glass toughening machines are primarily found in the building and construction industry and are used to make materials like glass doors, shower screens, glass floors, etc.

Depending on the type and application of the glass, there are a few different types of glass toughening machines.

• Horizontal Glass Toughening Machine:

This machine is mainly used to process flat glass. It can be used for the edges of the flat glass. As suggested by its name, it applies to the horizontal surface areas of the glass object. Once the glass is heated, it is rapidly cooled by air or water. This ensures that the glass material is both heat resistant as well as able to withstand temperature changes quickly.

• Vertical Glass Toughening Machine:

  This glass machine is often used for architectural glass items. These include items that typically have a vertical orientation, like windows and facades. The vertical machine has an oven that is split multiple times so that the glass can be heated evenly and properly.

  Double/Triple/Quadruple String Furnace machines: These types of glass tempering machines can run multiple glasses simultaneously as they are split furnace / multiple-string options. It helps improve efficiency and increase output. The machines are suitable for commercial volume production.

• Glass Laminating Machine:

  A glass laminating machine is used to laminate glass. It typically operates under vacuum and/or heat to bond the layers of the laminate together seamlessly. The interlayer is made from PVB, EVA or SGP. The glass laminating machine can be used for bleamed glass, laminated safety glass, etc.

Specifications and maintenance of glass toughening machines

Specifications

The specifications of glass tempering machines will vary depending on the type. Here are some key specifications buyers should know.

• Maximum Thickness: This is the maximum thickness of glass the machine can toughen. It varies with different machines. For instance, vertical tempering machines can toughen up to 19mm thick glass. Horizontal glass toughening machines can toughen glasses with a thickness of 4-12mm.
• Mesh Width: This is the width of the glass sheets a machine can process. The mesh width depends on the manufacturer. The vertical glass tempering machine can process glass sheets up to 2200mm wide. Horizontal machines, on the other hand, can only process up to 3200mm.
• Length: Glass toughening machines are long. For instance, the vertical type has an average length of 4500mm. Some machines even reach up to 8500mm. The longer the machine, the more the production efficiency.
• Compressor Power: The compressor powering the glass tempering machine must be powerful enough to handle the toughening demands of the glass. That means it should have sufficient flow and pressure capacity. For many machines, the compressor power is 37kw-45kw.
• Control System: Most glass toughening machines feature a computer control system that monitors and controls the entire tempering process. For instance, the L&L glass tempering machine has an advanced computer control system that lets the operator control various parameters. These may include temperature, time, and pressure. The control system also has safety features that prevent overheating, overpressure, and other dangers.

Maintenance

To maintain glass toughening machines, manufacturers recommend regularly scheduled preventive maintenance. Regular maintenance helps the machines achieve optimal performance. It also enhances their longevity. Here are some maintenance tips for toughening machines.

• Regularly wash and clean the machine. This will prevent the buildup of dirt, debris, and dust, which can affect performance.
• Inspect the machine components- the belts, gears, and bearings. Look for signs of major or minor damage. Repair or replace any worn or damaged parts.
• Lubricate all moving parts to reduce wear and tear. Lubrication also minimizes friction and ensures smooth operation.
• Check the air filters. Clean or replace them if they are clogged or dirty to ensure proper airflow and cooling.
• Check all electrical connections and wires. Ensure they are tight and free from corrosion. Electrical connections that are loose can affect the performance of the machine.
• Maintain a comprehensive record of repairs and services. This will help operators track the history of the machine. It also makes scheduling routine maintenance easier.
