LEADING TECHNOLOGY TO EXTRUDE FOAM WITH CO2 TURN-KEY solution concept XPS insulation boards begin as a solid granule. The granules are fed into an extruder where they are melted and critical additives are mixed with the viscous fluid that is formed. Then, a blowing agent is injected to make the mixture foamable. Under carefully controlled heat and pressure conditions, the foamable mixture is forced through a die, at which time forming and shaping occurs. The rigid foam is then trimmed to the final product dimensions. 

 

 Available specification of the foam board Thickness range - 20mm-120mm, variable with different formulation and also blowing agent.Width range - 600mm/1200mm, specified width could be required.Maxium capacity - up to 1000kg/hr. Blowing agent - optionally with CO2, HFC, butane etc.Base polymer - Polystyrene. Learn more about USEON's COMER  COMER series production line can produce better quality of final products is the result of the comprehensive understanding of single screw and twin screw extruders. COMER integrated the excellent mixing performance of twin screw extruder and cooling performance of single screw extruder. This provides the guarantee for higher capacity and better quality of final products. 

Raw material dealing solution  Automatic uploading units are configured to provide the fully automatic solution. Batch gravemetric feeding and premixing solution is also optional.USEON standard solution will equip the K-Tron loss-in-weight feeders for totally systematic solution.
Injection units for blowing agents  Precise metering and injection units for CO2, HFC or butane could be specificly confugered according to different requirement. Other liquid injection as added blowing agent could also be equipped.
Excellent twin screw extruders   All of the first plasticating extruders will be equipped with USEON's super powerful modular twin screw extruders with highest screw torque. Optimized screw profile permits all kinds of physical blowing agent injection condition. Best distributive and dispersion mixing condition are easily approached inside the speciallized extrusion units.
Patented cooling extruders   Modular structure of the cooling extruder allows the best cooling condition that could avoid the unbalanced cooling condition. Precise temperature control is easily assured through such design.
Melt homogeziation and die  All COMER systems equip the unique static mixer to get better temperature distribution and the further mixing.  USEON also develops the specialized die for CO2 extrusion system to meet the strict foam condition.
Post units  Post units include the calibrator, haul-off, edge trimmer, printer, stacker and autopacking units. These units are optional according to buyer's specific rquirements.
PCC interface   From relay to PCC (industrial computer control), we can customize the control system according to your specific requirements. We not only think about economical factors, more and more caring designs have been introduced to our control system, which makes the precise control easier.
