In the production of Sheng-An precision extrusion series, the common appearance adjustment of medical PVC hose products is generally divided into two kinds: fog surface and high permeability. The desired effect can be achieved by adjusting the extruder.

1. If the appearance needs the fog surface effect, you can make the following adjustments:

A. Reduce the extrusion temperature with no problem of plasticizing;

B. Add an air blowing device at the entrance of the water tank;

C. reduce the screw speed.

2. If the appearance needs high permeability effect, the following adjustments can be made:

A. Increase the extrusion temperature;

B. Increase screw speed.
