1. Unreasonable setting of heating temperature leads to uneven thickness of Stretch Film, because temperature directly affects the melt in the mold head flow channel
Flow pattern, and related to the longitudinal thickness distribution of the product, should check whether the heating device and temperature control device is damaged, each heating
Zone temperature is reasonable to ensure the stability of heating temperature.
2. Some die gap is not uniform, some parts of the gap is larger, some parts of the gap is smaller, resulting in the amount of extrusion
Therefore, the thickness of the tensile film formed is not consistent, some parts are thin, some parts are thick, then we only
To adjust the clearance of the head die mouth, to ensure uniform everywhere;
3. The air supply volume around the cooling air ring is not consistent, resulting in uneven cooling effect, so that the thickness of the stretch film appears uneven
Uniform phenomenon, then we need to adjust the cooling device, to ensure that the air volume of the outlet is uniform; If the traction speed is not constant and no
The change of the break will also lead to the uneven thickness of the produced stretch film, then check the mechanical transmission device to make traction
The velocity remains constant.
