A customer in New Zealand has received a customized LeFu LF1740-B4 Flatbed Applicator, a large-format laminating solution developed for signage, digital printing, graphic production, and other applications that require accurate film application on oversized substrates.
The LF1740-B4 combines a 1.6*4.0 m working area with adjustable warm and cold lamination and pneumatic roller control. This customized configuration gives print and sign businesses more working space for large panels while helping operators achieve a smooth, consistent finish.
A customized flatbed applicator for large-format work
Large-format graphics and rigid panels can be difficult to laminate with a conventional table. Limited working space may require repositioning the material, which can increase handling time and create alignment or bubble-related risks.
The 1.6*4.0 m format is suitable for handling long signage panels, printed boards, posters, PVC sheets, foam boards, and other flat materials within the machine’s working range.
Warm and cold lamination in one machine
The LF1740-B4 supports both cold and warm lamination. Cold lamination is useful for heat-sensitive materials such as printed vinyl and self-adhesive graphics. Warm lamination, with temperature adjustment up to 60°C, can support applications that benefit from controlled heat during film or adhesive application.
This flexibility allows users to select a suitable process according to the material, adhesive, and desired finish. Operators can adjust the working temperature instead of relying on a single fixed lamination method.
Pneumatic roller control for consistent pressure
The LF1740-B4 uses pneumatic control to raise and lower the laminating roller. A pneumatic roller system helps the operator apply pressure evenly across the working area and adjust the roller position according to the material thickness.
For a flatbed applicator, consistent pressure is important. Uneven pressure can contribute to wrinkles, bubbles, or inconsistent adhesion. By combining pneumatic roller control with a large, level working table, the LF1740-B4 is designed to support a more controlled lamination workflow.
The pneumatic system requires a suitable compressed-air supply. LeFu product information specifies an operating air-pressure range of approximately 6–8 bar for the pneumatic roller system.
Designed for signage and graphic production
The customized LF1740-B4 can support a range of flat application and lamination tasks, including:
●Applying protective film to printed signage
●Mounting graphics onto PVC, foam board, and other rigid panels
●Laminating posters and large-format digital prints
●Applying self-adhesive vinyl and reflective materials
●Working with flat panels up to the machine’s specified thickness and size
●Supporting warm lamination for selected adhesive and film applications
The machine is especially relevant to sign manufacturers, digital print service providers, display producers, and graphic workshops that need a larger working format than a standard flatbed applicator can provide.
A practical workflow for operators
The LF1740-B4 is designed to make large-format application more manageable for daily production. A typical workflow includes:
Prepare the material.
1. Clean the substrate and confirm that the printed graphic, film, and panel are suitable for the selected process.
Position the substrate.
2. Place the material on the flatbed and align it before starting the application.
Select the working temperature.
3. Use cold lamination or set a suitable warm-lamination temperature between 0°C and 60°C, depending on the material and adhesive.
Adjust the roller.
4. Use the pneumatic lifting controls to set the roller position and pressure for the material thickness.
Apply the film or graphic.
5. Operate the roller across the surface at a controlled speed to help reduce bubbles and wrinkles.
Inspect and trim.
6. Check the finished surface, then trim excess film where necessary.
Operators should always follow the supplied operating instructions and test the process on the selected materials before full production.
Why a larger working area matters
A 4.0 m-long working area can reduce the need to reposition long materials during lamination. Fewer repositioning steps may help improve handling efficiency and reduce the risk of alignment errors, particularly when working with long printed graphics or rigid panels.
The maximum material thickness of 50 mm also gives the LF1740-B4 additional flexibility for flat substrates that are thicker than ordinary posters or films. The exact result depends on the material, adhesive, surface condition, and operating settings.
LeFu support for customized equipment
Customization is important when a customer’s available space, substrate format, production method, or application requirements differ from a standard machine configuration. LeFu can discuss working dimensions, temperature requirements, roller functions, and other configuration details before production.
For equipment installation and operation, LeFu provides operating documentation and technical guidance. Customers should confirm the required power supply, compressed-air conditions, installation space, and material specifications before delivery.
A new step for the New Zealand customer’s production workflow
The delivery of the customized LF1740-B4 to New Zealand demonstrates how LeFu adapts flatbed laminating equipment to meet international customers’ large-format requirements. With its extended 1.6 × 4.0 m work area, 0–60°C warm-and-cold function, pneumatic roller control, and support for materials up to 50 mm thick, the LF1740-B4 provides a practical platform for signage and graphic-industry applications.
LeFu Laminator continues to develop flatbed applicators, flatbed laminators, cold laminators, hot laminators, and automatic laminating equipment for customers in different markets. If you need a customized flatbed applicator for large-format graphics or rigid-panel lamination, contact LeFu to discuss your required size and application.
