Compound co-extruding die mold

Compound co-extruding die in the die is melt into the mold all have their own port, and then gathered together in mouth anxious mode shape section extrusion. This type of co-extrusion die is under the pressure of compound in the mold, peel strength between the layers is larger, through the adjustment of the melt and die lip clearance adjustment, can control complex whole thickness distribution and the thickness of the melt layer.
mould compound co-extruding die melt manifolds shall be short as possible. Because of several kinds of melt flow in the same mould, not conducive to different temperature and viscosity of the melt flow of co-extrusion compound, in order to improve the melt rheological behavior of the different processing conditions, usually adding insulation device between the flow channel, but therefore the cause of the mould structure complicated, can not completely solve the problem. The mould is suitable for double color, soft and hard compound extrusion profiles, tubes.
