continuous screen changer for PET and PVB products

Special non-stop continuous screen changer for PET and PVB products is characterized by high transparency, high precision and relatively high forming temperature, such as BOPET, PET packaging tape, PET sheet, etc. The special network changer has the following characteristics:

(1) There are "special" exhaust mechanisms and runners. When changing the network, the gas in the new network can be discharged to keep the pressure balance of changing the network, so as to thoroughly solve the problem of "bubbles".

(2) The exhaust position is also the preheating position of the mesh block, which ensures that the temperature of the mesh to be replaced is the same as that of the mesh to be replaced, and avoids the crystallization of the melt due to the low temperature of the new mesh block, which leads to the worsening of the fluidity and even the appearance of crystalline points.
