Phenolic Foam automatic sandwich making machine

Phenolic foam automatic sandwich making machine: Thickness:20-100mm Pouring rate:2-10kg/min Aluminumchainplate: thickness 8mm

Remarks: the height of the sandwich panel that phenolic foam composed is from 20mm to 100mm, the flow rate that injector pours is from 2kg/min to10kg/min, and the thickness of the aluminum chain plate is 8mm. 

1. Equipment requirements:

1.1 Description of the production line

This continuous production line is specially used for manufacturing of phenolic foam sandwich panel, the facing sheet can be foil-sided sheet, single facing of color-steel, single facing of foil sided, and other soft facing sheet. The finished goods (panels) can be used for central air-conditioning duct and wall-cladding insulation materials.The panel thickness coming out is varies form 20 mm to 100mm, the width is 1200mm and the length determined by customers.

1.2 Woring principle 

The raw materials of phenolic resin liquid are delivered into the mixing head in a given ratio through the metering pump on the injector after the raw materils of phenolic resin liquid premixed, then injected onto the sandwich of top facing sheet and bottom facing sheet and along with the heating laminator, formed the sandwich panel and get the finished products after go through on line trimmer and cutting machine.
