What should be paid attention to when using a single screw barrel?

A single screw barrel is a screw groove with a fixed groove depth. In addition to the main functions of mixing, melt output transmission and measurement, it should also provide sufficient pressure to maintain uniform melt temperature and stabilize the flow of melt plastic. Measure the length of the line segment and the mixing effect is very good. If the metering segment is too long, the melt stays for too long, which is prone to pyrolysis. If it is too short, it is easy to make the temperature uneven.

Precautions for using a single screw barrel:

1. Make sure that the unit installation work is installed as required, and make sure that each bolt is tightened.

2. Check the lubricating oil in the deceleration and pneumatic, and check the lubrication of each mechanical transmission component.

3. When checking the power supply device and the biography component, each component must be safely grounded.

4. The barrel is full of plastic, plastic, and the temperature does not meet the requirements, and it is forbidden to start.

5. There must be no foreign matter in the substrate, and iron or other unnecessary materials are mixed into the raw materials.

6. The material must be dry, otherwise it must be pre-dried.

7. Check whether the unit heating system and temperature measurement system are intact.
