High frequency curved plywood bending foam press machine

Product Overview

Using high-frequency (HF) heating and 3D hydraulic pressing, it achieves 99% glue curing efficiency in 3–5 minutes—a fraction of the time required by steam bending (30–60 minutes). This machine is indispensable for manufacturers producing curved plywood components for furniture, automotive, and marine industries, where design flexibility and production speed are critical.

Product Advantage

1. Advanced Heating Technology

Internal Curing: HF energy penetrates the glue layer directly, generating heat within the adhesive via molecular friction. This eliminates hotspots and ensures uniform bond strength (≥8 MPa shear strength) even for thick laminates (10–30 mm), with glue curing depth controlled to ±0.5 mm.

Rapid Cycle Times: Compared to traditional steam presses (30–60 minutes per cycle), the HF machine reduces processing time by 80%, enabling mass production of curved components (e.g., 500+ chair frames per day) without compromising quality.

2. 3D Shaping Capability

Multi-Axis Hydraulics: The press features vertical and horizontal pressure units with servo-controlled cylinders, allowing simultaneous shaping of complex geometries like chair arms, sofa frames, and boat hulls with radius as small as 50 mm. Custom molds (made from plywood or MDF) can be quickly swapped (within 15 minutes) to accommodate design changes.

Precision Control: A 15-inch touchscreen interface lets users input pressure (75–135 tons), temperature (120–180°C), and cycle time, with 100+ programmable presets for consistent results across batches. Pressure is distributed uniformly (±2% variation) across the mold surface to prevent deformation.

3. Eco-Friendly and Cost-Effective

Energy Savings: HF heating targets only the glue layer, consuming 50% less energy than conventional steam presses (0.8 kWh per kg of plywood processed). The machine also eliminates the need for boilers or hot oil systems, reducing infrastructure costs by 40% and lowering carbon emissions by 30%.

Low Maintenance: The stainless steel mold platens (304 grade) resist corrosion and wear, requiring minimal upkeep (annual inspection only). Mold replacement is simplified due to the machine’s quick-release mechanism, cutting downtime by 30% compared to bolted systems.

Applications

Furniture Design: Creates curved plywood for ergonomic chairs, coffee tables, and shelving units. The machine’s 3D pressing allows for seamless integration of structural supports and decorative elements, with curved components achieving a surface finish (Ra ≤3.2 μm) suitable for direct painting or varnishing.

Automotive and Aerospace: Produces lightweight, impact-resistant components like car dashboards, aircraft interior panels, and train seat frames. The high-strength bonds withstand extreme vibrations (10–2000 Hz) and temperature fluctuations (-40°C to 80°C) encountered in transportation.

Marine Industry: Forms waterproof curved plywood for boat decks, hulls, and cabins, with the HF curing process ensuring long-term resistance to moisture and delamination. Plywood components meet IPX7 waterproof standards, making them suitable for constant exposure to water.

Architectural Installations: Used in curved wall panels, spiral staircases, and dome ceilings for commercial spaces (hotels, museums, airports), where both aesthetics and structural integrity are critical. The machine’s ability to shape large panels (up to 3000 x 1500 mm) enables bold architectural designs.
