Equipment used

• One “1+1” double-layer laminator for steel Panel
• One set of PU foaming machine

Operating principle

The sandwich panel consists of double layer CORRUGATED panel,the foam will be between these panels.The double-layered laminator is consisted of the press and the rail stands.Initially, put the top and the bottom facing sheets inside of mould frames and then do the necessary sealing work. After that, feed the worktables into the press. When worktables inside the press moves out orderly, the other two feed in at the same time. Upon the finish of feeding, the press will close and slant at a angle, waiting for the injection PU raw materials from the PU mixing head into different panels. Meanwhile materials start foaming and curing. At this time, mould frames on worktables moved out can be opened and the finished products can be unloaded to get ready for next production cycle.

Constituents of equipment

a. One “1+1” double-layer laminator for corrugated pane.

The laminator is used to make sandwich panels with the max. lenth of 6m, max. width of 1.0m and the thickness 30mm.

1. Main technical parameters

• Thickness of a sandwich panel: 30mm
• Max bearing force: 0.2Mpa/cm2
• Moving speed of worktable: 15-20m/min
• Pressing speed: 10-30mm/s
• Working temperature of worktable: 0-50℃

2. Main machine
To be made up of the frame, chassis, slanting mechanism, rails and beam.

• Worktable

Worktables are made of extruded aluminum alloy.
Worktable (is fixed),manual-feeding ,and mould locators are provided.

• Worktable heating system

It is made up of the medium heating installation, pump units, pipes and suitable temperature control. (Two sets, one on the right, the other on the left)

• Electric control system

Adopting central control by a panel, the system is equipped with fitting press buttons, relays, temperature control instrument, etc..

b.Hi-pressure PU foaming machine

Tank assembly

• Producing tank: Two 300L , maximum allowable pressure 0.4MPa. Each tank is with a 0.75kw agitator assembly and the safety valve, pressure-reducing valve, pressure gauge, three-position liquid-level control switch and fitting valves and pipes.
• Automatic material-supplementing installation: two material-loading tanks included; material loading done either in an automatic or a manual way.
• Material filtration part includes two wire-type filters.

Electrical control
One control cabinet, on which pressure, temperature, flowrate, alarm and digital display are given.
