How to Achieve High-Quality, Stable Pressing of CCL? An In-Depth Look at our 2500T Vacuum Press Solution

How to Achieve High-Quality, Stable Pressing of CCL? An In-Depth Look at our 2500T Vacuum Press Solution

In industries like composite materials, advanced CCL, and PCBs, do you face these challenges?

Bubbles or layers forming during pressing?
Inconsistent results between batches due to uneven temperature?
Slow heating, high energy use, and low efficiency with traditional presses?
Too many manual steps causing safety risks?
Difficulty tracking process data when quality issues arise?

These problems affect both product quality and your bottom line.

To solve these challenges systematically, a modern automatic vacuum press system is no longer optional—it’s essential. Let’s explore how the2500T Two-Hot-One-Cold Vacuum Presstackles these issues through smart engineering and reliable automation.

Challenge 1: How to Ensure Extreme Stability and Long Life Under High Pressure?

Large traditional presses often suffer from high hydraulic pressure, frame stress, and frequent maintenance.

Our solution:

Large Cylinders, Lower Pressure
- Two 800mm diameter cylinders
- Deliver 2500 tons of force at only25 MPa
- Result: longer component life, less leakage, smoother operation
Dual Hydraulic Systems
- Two independent pump sets—one acts as a backup
- Switch seamlessly if one fails
- Value: uninterrupted 24/7 operation
Strong Full-Frame Construction
- Welded steel frame, reinforced with high-strength bolts
- Easy-access maintenance doors on the rear

Challenge 2: How to Control Temperature Evenly and Respond Quickly?

Temperature consistency is critical—even small variations can change product properties.

Our approach:

Optimized Heating Channels
- Designed for even heat flow across the plates
- Maintains temperature within ±2.5°C
- Heats up 25% faster than conventional systems
Smart Multi-Stage Control
- 16 programmable temperature stages
- Fast-response RTK pneumatic valves adjust in under 1 second
- Fits various materials: resin-based, ceramic, and more
Efficient Cooling
- Combined shell-and-tube + plate heat exchangers
- Cold press uses dual-in/dual-out design—35% more efficient
- Metal hoses between layers prevent stress damage

Challenge 3: How to Automate Material Handling Completely and Safely?

Manual handling is slow, risky, and hurts consistency.

We automate it:

“Floating” Plate Loading System
- SKF high-temperature bearings guide each plate smoothly
- Loads 15 layers at once, positions within ±0.5mm
- No jamming or scratching
Intelligent Transfer System
- Gear-and-rack drive with heavy-duty linear guides
- Smooth starts and stops using frequency control
- Coupling mechanism locks the frame during transfer—prevents tilting
Complete Safety Interlocks
- Mechanical + sensor-based position checks
- 28 safety rules: cart can’t move while pushing plates, rack can’t lift while loading, etc.
- Safe access platforms with railings included

Challenge 4: How to Create and Control Vacuum Precisely?

Vacuum quality directly affects product density and integrity.

Our vacuum system:

High-Efficiency Pump Setup
- 2 NASH liquid ring pumps (stainless steel internals)
- 2 Shanghai Diwei roots pumps for boosting
- Reaches working vacuum in under 3 minutes
Smart Vacuum Management
- Set upper/lower limits and hysteresis on the touchscreen
- Delay start function (0–99 minutes)
- Energy-saving mode: pumps idle once vacuum is reached—cuts power use by 40%

Challenge 5: How to Track Every Process and Ensure Traceability?

In Industry 4.0, data is your most valuable asset.

Our digital platform delivers:

Real-Time Monitoring
- Live curves show temperature, pressure, and vacuum for up to 3 hot presses
- 9 material temp points (hot press) + 3 points (cold press)
- Alerts if any plate deviates ±5°C from average
Easy Recipe Management
- Store 100+ process recipes
- Sync recipes to multiple presses with one click
- Enter board size—system auto-calculates required pressure
Full Data Logging
- Records temperature, pressure, vacuum, and time for every batch
- Keeps data for 2+ years locally
- Export to Excel via USB—ready for your MES system
Uninterrupted Operation
- 2-hour UPS keeps computer and controls running during outages
- Auto-resume from where it stopped—no batch loss
