Cost-Efficient EVA Glass Laminating Machine for Flexible Batch Production
The SG-3000-2SD provides glass processors with a practical way to produce professional EVA laminated glass while maintaining a controlled equipment and facility investment.
Its streamlined single-chamber design accommodates two silicone vacuum bags, enabling manufacturers to process one or two loads according to order volume. Medium-wave infrared heating, Siemens PLC process control and a dedicated vacuum system provide the essential functions required for stable EVA glass lamination.
The furnace is available in two standard processing sizes:
- 2200 × 3300 mm
- 2500 × 4000 mm
With a maximum laminated glass thickness of 50 mm, the SG-3000-2SD can produce a broad range of safety, decorative and functional glass products for architectural and interior applications.
One EVA Laminating Machine, Multiple Product Opportunities
EVA Safety Laminated Glass
The furnace can produce EVA safety laminated glass for doors, partitions, shower enclosures, wall panels, furniture and other architectural or interior applications.
EVA film bonds the glass layers and helps retain glass fragments following breakage. The finished glass construction should be verified according to the selected EVA film, applicable standards and project requirements.
Decorative Laminated Glass
Compatible decorative materials can be incorporated between glass sheets with suitable EVA film, including:
- Silk and fabric
- Paper and printed designs
- Colored EVA film
- Decorative plastic films
- Metal mesh
- Fibers
- Other heat-compatible inserts
This allows glass manufacturers to offer customized decorative glass for hotels, retail interiors, offices, residential projects, partitions, doors and furniture.
PDLC Smart and Privacy Glass
With suitable EVA and PDLC films, the SG-3000-2SD can produce smart glass, privacy glass and electrically switchable glass.
These products are widely used for office partitions, meeting rooms, hotel bathrooms, medical spaces, residential privacy systems and commercial interiors.
Why Choose the SG-3000-2SD?
Controlled Initial Investment
The SG-3000-2SD uses a streamlined single-chamber structure developed for manufacturers with moderate production requirements.
It provides the essential vacuum, heating and process-control functions required for professional EVA laminated glass production without the investment associated with a larger multi-chamber furnace.
One Chamber with Two Vacuum-Bag Positions
The processing chamber accommodates two silicone vacuum bags.
Manufacturers can process:
- One load for individual or urgent orders
- Two loads simultaneously for increased batch output
- Different glass sizes within the available chamber capacity
- Custom and repeat orders according to production demand
This arrangement provides useful production flexibility without unnecessary equipment complexity.
Medium-Wave Infrared Heating
The SG-3000-2SD uses medium-wave infrared heating to transfer thermal energy directly to the laminated glass assembly.
The infrared heating system provides responsive temperature adjustment and efficient heating throughout the programmed lamination cycle. Combined with Siemens PLC control, it supports stable processing across different glass thicknesses, EVA films and loading quantities.
Compared with a larger forced-air circulation structure, the infrared design allows the furnace to maintain a more compact configuration and lower installed power.
Siemens PLC Process Control
Once the prepared trays have been placed inside the chamber, the Siemens PLC automatically controls the programmed lamination process.
The control system manages key parameters such as:
- Vacuum
- Heating
- Temperature
- Processing time
- Programmed process stages
PLC-based control reduces repeated manual adjustment and helps maintain consistent production conditions between different batches.
Stable Vacuum Performance
One vacuum pump provides the vacuum required for the two silicone vacuum-bag loading positions.
Stable vacuum extraction helps remove trapped air from the laminated construction and supports consistent bonding between the glass and EVA film.
The specified vacuum level reaches up to approximately −101 kPa, depending on operating and environmental conditions.
Lower Installed Power and Facility Requirements
The SG-3000-2SD has a reference installed power of approximately 40 kW.
Its compact single-chamber design and medium-wave infrared heating system make it suitable for factories seeking to introduce or expand EVA laminated glass production while controlling:
- Initial equipment investment
- Electrical capacity requirements
- Factory-space requirements
- Daily operating costs
- Equipment complexity
Autoclave-Free EVA Glass Lamination
The SG-3000-2SD uses silicone vacuum bags, controlled vacuum and infrared heating to produce EVA laminated glass without a high-pressure autoclave.
This avoids the investment, installation complexity and pressure-vessel requirements associated with an autoclave-based production system.
It is particularly suitable for glass processors whose production includes customized glass, mixed orders and small-to-medium production batches.
How the SG-3000-2SD Works
1. Prepare the Glass
The glass is cleaned and assembled with the selected EVA film. Decorative or functional materials can be incorporated according to the intended product.
2. Prepare the Vacuum Bags
The assembled glass is placed inside a silicone vacuum bag. The bag is sealed, connected to the vacuum system and positioned on the loading tray.
3. Load the Chamber
One or two prepared vacuum-bag loads are placed inside the single processing chamber.
4. Start the PLC-Controlled Cycle
The operator sets the required vacuum, temperature and processing time through the control system.
Once the cycle starts, the Siemens PLC automatically manages vacuum extraction, infrared heating, temperature and programmed processing time.
5. Cool and Unload the Glass
After the heating cycle, the trays are withdrawn and transferred to the designated cooling area. Once sufficiently cooled, the laminated glass is removed from the vacuum bags and inspected.
Depending on the glass size, thickness, loading quantity, EVA film and selected process settings, one production cycle normally takes approximately 40–150 minutes.
