Short Cycle Melamine Hot Press Machine for The Plywood Film Face Veneer

Product Overview

Featuring a 4X8 feet working table (1220mm×2440mm), this machine accommodates panels up to 30 mm thick with a remarkable ±0.3 mm flatness tolerance after pressing—critical for ensuring uniform adhesion across large surfaces. Its PLC-controlled multi-zone heating system divides the platen into 6 independent heating zones, each maintaining temperature accuracy within ±2°C, ensuring consistent heat distribution even for panels with varying density profiles.

A rapid cooling cycle follows the heating phase, utilizing water-cooled platens to reduce panel temperature from 200°C to 50°C in under 60 seconds, minimizing post-press warping by 70% compared to air-cooled systems. The intuitive touchscreen HMI interface allows operators to program custom pressure profiles, such as gradual pressure ramping for air-sensitive adhesives, ensuring void-free bonds for even the most delicate materials.

Product Advantage

1. Advanced Hydraulic System for Precision Bonding

The press’s performance is driven by double-acting hydraulic cylinders with a combined thrust of 500kN, delivering ±2% pressure accuracy across the entire platen surface. This precision prevents common issues like over-compression (which thins panels beyond specification) or under-bonding (which leads to delamination). A closed-loop pressure sensor with 0.1 PSI resolution continuously monitors force during the pressing cycle, making real-time adjustments to compensate for variations in substrate thickness or density.

2. Short Cycle Technology for High Throughput

Designed for maximum productivity, the machine’s preheated platens (with a temperature rise rate of 5°C per minute) eliminate the need for lengthy heat-up phases between cycles. Its rapid approach speed (100 mm/second) minimizes non-productive time, reducing total cycle time by 40% compared to conventional presses. This efficiency enables production rates of 120–180 panels per hour for standard 4X8 feet panels—equivalent to 1,000+ panels per 8-hour shift.

An integrated vacuum system with -0.08MPa suction removes trapped air between layers before pressure application, achieving 99.9% void-free bonds—a requirement for high-visibility applications like furniture surfaces and architectural panels. The vacuum chamber covers the entire platen area, ensuring uniform air extraction even for panels with complex edge profiles or cutouts.

3. Safety and Durability

Safety is embedded in the machine’s design, featuring dual emergency stop buttons (front and rear), interlocked safety guards that halt operation if opened, and a pressure relief valve that prevents over-pressurization beyond 1500 PSI. These features ensure compliance with international standards including CE, OSHA, and ISO 13849-1.

The press’s 304-grade stainless steel platen surface resists corrosion from phenolic resins and melamine adhesives, maintaining consistent performance over 100,000+ cycles. A forced air cooling system circulates 500m³/h of air through the hydraulic oil reservoir, reducing oil temperature by 20°C during continuous operation and extending seal and pump lifespan by 30%.
