One side loading and unloading HPL  production line mainly consists of vacuum sucker, paper batching unit,  conveyors, lifting in-feed/out-feed device, movable loading/unloading device,  pusher-puller, hot press etc.

Step 1: Vacuum sucker set the paper stacks  on paper batching unit
Step 2: Lifting in-feed device push each  stack into movable loading device
Step 3: After all layers are full, movable  loading device moves to front of hot press
Step 4: Pusher-puller push all layers into  hot press one time.
Step 5: Hot press starts to press with  heating and cooling simultaneously
Step 6: After finished, pusher-puller will  pull out all layers into movable unloading device
Step 7: Unload finish panels one by one  though lifting out-feed device and vacuum sucker.

Hot  Press
1. Hot press can heat/cool at the same  time, to meet technical requirement of production for high quality finished  laminates.
2. Heating/cooling system: steam heating  and water cooling or Overheating water heating and water cooling.
3. Size of finished laminates: 4'×8',  5'×8', 5'×10', 5'×12', 7'×9', 7'×14'.
4. Specific pressure: 80-120kg/cm²
Hydraulic  System
1. Low pressure and big flow hydraulic pump  group is used in hydraulic system to increase the production capacity by  reducing press closing time. High pressure big/small flow hydraulic pump are  adopted for energy saving.
2. Mechanical cycle includes loading, press  closing, pressure building up and releasing, press opening.
Electrical  Control System
1. HPL hot press is controlled and  monitored by PLC and visualization system to fulfill its function
2. PLC are from Siemens, Omron or any other  brands per customer's individual requirement.
3. Operating console near the equipment  makes the operation more convenient and faster.

One  Side Loading And Unloading HPL Production Line Characteristics
1. The hot press is with frame body, with  good strength and high rigidity.
2. Oil cylinder adopt new design sealing  kits, more wear-resistant, can keep the operating pressure.
3. The steam and cold water by turns can  heat and cool the hot platens.
4. The hot platen is filled with flexible  metal hoses with reasonable layout, can quickly heat the hot platen.
5. Synchronization mechanism adopts  gear-rack drive, can steadily lift the movable beam.
6. With Automatic thermo-measuring  instrument, hydraulic system adopts large over-flowing, low-noise vane pump and  high pressure plunger pump, can meet the technological requirements(closing  time and working speed).
7. Hot platen is made of superior carbon  structure steel, with fine grinding surface. Flatness≤0.06mm,  smoothness 1.6. High precision, high strength, more durable.
8. Heating system: step-by-step design, low  energy-consumption, uniform thermal conductivity, temperature adjustable;  uniform temperature-keeping, temperature tolerance ±3℃
9. Hydraulic system: mainly adopt imported  hydraulic components, pressure is adjustable.
10. Automatic control, only need to press  the button: the hot press can finish the whole working process, including hot  platens go up, closing, adding pressure, keeping pressure, timing, going down.

HPL  Press Applications
With beautiful appearance, fire-proof and  durable application, HPL laminates have been widely used in many fields, e.g.  high-class kitchen cabinets, office furniture, industrial decoration, interior  decoration of ship and exhibition material.
