Purpose:

This unit is suitable for blowing high-density polyethylene (HDPE), low-density polyethylene (LDPE), and linear low-density polyethylene (LLDPE) plastic films, which are widely used for packaging household and industrial products such as food, clothing, textiles, and daily necessities.

Features:

1. The screw and barrel are both made of 38CRMOALA alloy steel, which has undergone nitriding treatment and precision machining. It has high hardness, strong corrosion resistance, and durability;

2. The die head is plated with hard chromium, and its structure is spiral core shaft type. The extruded molten material is uniform, and the blown film has good smoothness;

3. The winding device adopts pressure controlled winding or center winding, and is adjusted by a torque motor. The winding is smooth and easy to change.

Usage:

1. Check that the temperature self-control is intact, the heating appliances are intact, and pay attention to timely adjusting the heating temperature at each point within the specified range.

2. Check the traction speed and control the film thickness.

Observe and adjust the uniformity of the film thickness, and ensure that the bending diameter meets the standard.

4. Check the pressure of the air storage cylinder, it should not be too high, but there should be a backup pressure.

5. Check and control the proportion of raw materials and mix them evenly.

⒍ Check for impurities in the raw materials, especially by promptly using a magnet to check for any iron mixed in.

7. Check the lubrication condition of the gearbox position and air compressor cylinder lubricating oil.

Regularly check the temperature rise and mechanical transmission of each operating motor.
