Modular Vacuum Membrane Presses are designed for a wide range of sandwich panel applications, using room-temperature curing adhesives to create strong, consistent bonds. Multiple vacuum modules can be bolted together to create a press that meets specific size and production requirements. LT Machines has designed and exported large industrial vacuum presses measuring over 18 metres in length.
Modular Large Vacuum Presses for Industrial Use
Modular large vacuum presses are ideal for manufacturers producing multiple sandwich panels, composite panels, and laminated components. Several stacks of panels can be pressed at the same time, making these machines suitable for both high-volume production and specialist manufacturing.
The flexible membrane system allows the vacuum press to laminate flat, curved, and shaped panels from a wide range of materials. Machines can be configured with unloading options including suction lifters or a built-in castor system, allowing cured panels to be easily removed from the press.
Our highly efficient vacuum pumps achieve pressures of up to 9.5 tonnes per square metre, providing reliable and consistent bonding performance. Automatic cycle timers and vacuum controls allow the system to operate efficiently and can enable the press to be left running automatically at the end of a shift.
Modular Presses for Larger Panels
For panels over 3 metres in length, or applications where panel sizes and shapes vary, modular large vacuum presses provide a flexible and cost-effective solution. The modular design allows additional sections to be added as production requirements change, avoiding the need to replace the complete machine when larger capacities are required.
The flexible membrane can accommodate different panel sizes and stack heights, while maintaining even pressure across the entire surface. Maximum bonding pressure is 15 PSI, with most applications typically operating between 6–12 PSI.
A major advantage of a modular vacuum press is its ability to adapt to changing customer requirements. Whether manufacturers need to increase capacity, produce larger panels, or respond to changes in industry standards, additional modules can be added quickly and efficiently.
Curved Vacuum Presses for Shaped Panels
LT Machines manufacture vacuum presses for bonding a wide variety of sandwich panels and composite materials used in industries including furniture, marine, automotive, and construction.
For contoured panels, complex shapes, and lower-volume production, an LT Clamshell Press provides an effective solution. These curved vacuum presses feature robust construction, powerful vacuum pumps, and self-sealing membranes with high stretch capability, allowing manufacturers to achieve accurate bonding results on challenging shapes.
A vacuum membrane press provides even pressure distribution across the panel surface, making it ideal for applications where traditional pressing methods may struggle. LT Machines has built over 2,500 Clamshell machines for customers worldwide.
Further Benefits
Vacuum presses provide several advantages compared with hydraulic and mechanical presses. They require less power, have lower floor loading requirements, and typically involve reduced maintenance, making them an economical choice for many manufacturing environments.
These machines can bond a wide range of curved and shaped panels, including decorative architectural panels, furniture components, marine panels, and specialist composite products. Support tooling is required for shaped panels, but this can usually be produced by a competent carpentry workshop.
With over 30 years’ experience in bonding contoured panels, LT Machines provides expert guidance on tooling design and press configuration. Our machines feature a robust chassis, flat laser-cut bed surface, and Roll Out Flexible Membrane system for fast, reliable operation.
Our energy-efficient, oil-lubricated vacuum pumps deliver consistent vacuum levels with minimal maintenance. For applications requiring controlled temperature as well as vacuum pressure, LT Machines can also advise on heated vacuum press solutions tailored to specific materials and adhesive requirements.
