Understanding the Different Types of Veneer Presses

Introduction

Veneer presses are essential machines in woodworking, but not all presses are built the same. Depending on your production needs, one type of veneer press may be more suitable than another. From traditional hydraulic presses to modern vacuum systems, understanding the different categories will help you choose the right equipment for your workshop. In this guide, we break down the types of veneer presses available and explain how each works, along with their typical applications.

Hydraulic Veneer Presses

Hydraulic presses are the workhorses of veneer pressing. They use hydraulic cylinders to exert significant force on large flat platens, pressing veneer sheets onto substrates with high pressure. Hydraulic veneer presses are ideal for flat panels such as tabletops, cabinet boards, and doors:

• High Pressure and Rigid Construction: A hydraulic system can apply several tons of force, ensuring a very strong bond even with thick or dense veneer materials. They feature solid steel frames and platens to maintain even pressure on large sheets (e.g. 8 ft x 4 ft panels). The result is a flat, bubble-free veneered panel.

• Heated or Unheated Platens: Many hydraulic presses, including the Kocayusuf models offered by J&C O'Meara, come with the option of heated platens (hot plates). Heated platens are useful when using glues that cure with heat, as they can significantly speed up the veneering process and improve adhesive bond strength. Cold (unheated) presses rely on standard wood glues with longer curing times.

Hydraulic presses are a top choice if you need to press large, flat panels and you value maximum bonding strength. J&C O’Meara offers single-opening hydraulic presses for general use, as well as custom designs for specific products.

Vacuum Veneer Presses

Vacuum veneer presses take a different approach by using atmospheric pressure. Instead of rams pushing a platen, a vacuum pump removes air to create pressure that presses the veneer onto the substrate. These presses usually consist of a vacuum pump and a flexible membrane or bag:

• Uniform Pressure on Any Shape: A vacuum press applies even pressure (approximately 0.8 bar, or about 12 PSI) across the entire surface of the workpiece, regardless of shape. This makes it excellent for irregular or curved pieces that a flat press can’t fully contact. The flexible membrane conforms to contours, ensuring even bonding. (Our Kocayusuf MP3 membrane press even features an automatic pin system to simplify setup for smaller pieces.)

• Easy Operation: Vacuum presses are relatively straightforward to operate. You place your glued veneer and substrate inside the vacuum bag or under the membrane, seal it, and the pump does the rest. Setup is quick without adjusting heavy platens or numerous clamps, and maintenance is minimal (mainly keeping the pump and seals in good condition).

Vacuum presses don’t exert the extreme pressure of hydraulic presses, but they provide more than enough for standard veneer work and have the unique benefit of handling shapes a platen press cannot. They are a go-to solution for custom shops or any application involving curved or intricate components.

Multi-Daylight Presses

“Daylight” refers to the gap between platens in a press. A multi-daylight veneer press is essentially a hydraulic press with multiple press levels stacked above each other. Instead of pressing one panel at a time, you can press several in one cycle (one per level):

• Higher Throughput: If you need to produce veneered panels in volume, multi-daylight presses greatly increase efficiency. For instance, a press with 3 daylights can press three panels at once, tripling the output per press cycle.

• Even Heating: These presses often include heating elements on each level, so all veneers cure uniformly. This is important in industrial settings where consistent quality across all pieces is required.

Multi-daylight presses, such as the Kocayusuf models available through J&C O’Meara, are well-suited for factories making large batches of veneered boards or panels each day. By pressing multiple pieces simultaneously with equal pressure and temperature, they ensure uniform quality at a high production rate.

Specialised Veneer Presses

Beyond the main categories above, there are also specialised machines for particular tasks. For example, a membrane press extends vacuum pressing into 3D lamination (useful for wrapping vinyl or complex shapes), and an automated door press streamlines the veneering of doors or large panels by integrating feeding and pressing in one system. Such niche presses are invaluable for manufacturers with specific needs.

Conclusion

From powerful hydraulic presses to flexible vacuum systems, the world of veneer presses offers a solution for every veneering challenge. Understanding these types of presses will help you determine which machine aligns best with your products – whether you need high-pressure flat pressing, the ability to veneer curves, or high-throughput production.
