1.Short cycle lamination line Key pump,valve,sealing from european brand., 2.Press frame upper down ratio bigger, 3. temperature - details see: https://www.machineto.com/short-cycle-lamination-line-10344221

SHORT CYCLE LAMINATION LINE

1) The design idea of press is same as european product. The frame of press has high parallelism and surface flatness and high precision for long time. Even after many years usage in case of change of precision of press frame, it can be re-adjusted to refresh precision. While press frame of other suppliers adopt whole body welded structure so that in case of change of precision, it can not be refreshed. This point is especially key for shorten hot pressing time, improve capacity and guarantee quality.

2) Press frame is improved so that running is more stable and whole rigidity of press frame is stronger. Upper and down beam ratio of press frame is much bigger that other suppliers so that safety coefficient is bigger and it can satisfy long time uasage of end user.

3. )There is one high molecule insulation block (it can use for long time and it can bear high temperature and high pressure) between main cylinder piston and hot pressing plates. While other suppliers only use common insulation pad. There are on pc steel bracket on upper side of insulation block so that rising temperature of cylinder is small and sealing usage time is extended.

4.) Temperature control system can make temperature precision of hot pressing plate as +- 1.5 centigrade. It is essential for quailty of laminated board . While none other chinese suppliers can reach.

5.) Auxiliary time of press is less than that of other suppliers. One Pakistan customer can reach 2 pcs in one minute in actual production. Also the press can work for long time with such high frequency. None other chinese suppliers can reach above .

6.) Electrica magnetic changing direction valve and pressure control valve adopt BOSCH / REXROTH brand.Other suppliers adopt chinese brand .

7.) separate cooling filter circulation pump system so that oil liquid in oil tank will always be clean and cooling status. Other suppliers do not have such separate cooling filter circulation pump system .

8.) The following imported brand are used for electrical elements.

Programmable logic control unit Mitsubishi

I/O Mitsubishi

main switches Schneider
protective motor switches Schneider

Power contactors Schneider
Contactor relays Telemecanique/ Weidmüller

Push buttons and switches Schneider

Signal lamps Schneider

Terminals Weidmüller

Frequency inverter YASKAWA

While other suppliers may only use plc as imported brand.

9. )Main cylinder sealing adopt european brand. While other suppliers adopt chinese brand so that oil leakage and usage life of sealing is short and change frequently and maintenance cost is higher and breakdown rate is higher.

10.) Tie-in type Pressure gauge of main cylinder is changed to electrical type pressure relay. While most other suppliers only adopt Tie-in type Pressure gauge with low reliability.

NEW IMPROVEMENTS

1) Press frame thickness change to 50 mm instead of 45 mm.

2) Connecting type of press frame had been improved with better stability.

3) Installation of insulation block between down hot pressing plate and press frame is more reliable and will not have displacements.

4) Previous dia of synchronizing shaft is @60 and now it is @75. Previous middle part of synchronizing shaft does not have supports and now middle part of synchronizing shaft has supports. Previous two ends of synchronizing shaft adopt self-aligning ball bearing and now it adopts self-aligning roller bearing with better stability and longer usage life.

5) Main cylinder body now adopts whole body casting and previously main cylinder body is welding type. The type of Oil receiving tray under main cylinder is also improved with better reliability.Sealing of main cylinder is more reasonable than previously and guiding distance extended and sealing quantity more and also materials of sealing ring better and usage life extended.

6) SS upper caul plate tension adopts tension hook with more reliability which will not make caul plate hang down . Previously it adopts spring tension.

7) Hydraulic station will be put on the ground and it will be easy for maintenance and will not be influenced by heat radiation. Also hydraulic station has water cooling .

8) Hydraulic pump adopts Rexroth technology pump with longer usage lifetime.

9) Connection of prefill valve of oil tank change to steel pipe plus reelability connection with better reliability and previously it is soft pipe connection.

10)Valves of temperature control system now adopt top Chinese brand.
