Hollow profile, Multiwall sheet
The structure of Multiwall sheet is formed a construction of male set in a die for the production of Hollow profile.
On one extrusion die it is possible to set one size of male, as a result - for the production of various amount of structures of Multiwall sheet, the different amount of extrude dies is needed, but it in same queue not cheap. One extrusion die in Europe costs an about 200000 euro, in China 30000 dollars. Here such here difference.
Also on one extrusion die with one construction of male, it is possible to make a few size, thicknesses, Hollow (Multiwall) sheet with the identical design of structure.
