1.smaller figure and cheaper than continuous line, 2.suitable for building refrigerator house and other small constructions. - details see: https://www.machineto.com/discontinuous-pu-sandwich-panel-product-line-10079326

Brief introduction

The product line is consisted of the press and the rail stands. Two worktables are to move into the press and the other two stay on 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.

Advantages:

1.panels are produced faster than conventional ones: demoulding times are 30-35% shorter

the average distribution foam - at equal overall density - is better than in conventional panels

2. scrap parts - and all relevant disposal or repairing costs - are virtually eliminated nice and clean quality panels are supplied, with very high

mechanical properties and state-of-the-art insulation efficiency
