How To Use The Plastic Extrusion? A Comprehensive Guide

Let’s introduce how to use the plastic extrusion (From Wiki Article)? A comprehensive guide for you.

How To Use The Plastic Extrusion?

Check the temperature control, instrument panel and cooling water.

First, before starting the plastic extrusion, you should check the following conditions:
Are there any problems with the temperature control, instrument panel, or cooling water?
Inspection method: Detection with thermometer and cooling water.
Heat the extrusion screw, barrel and die according to the extruder operating procedures.
After the temperature rises to the set temperature, warm it up for a few minutes before turning it on.

Extrude the raw materials evenly.

Secondly, before starting the machine, tighten the connecting screws and bolts of each part of the die head. Before the extrusion extrudes raw materials, the operator should not stand in front of the mold to avoid injury.
When the extruder starts to extrude, the screw speed should be slow at first and then gradually speed up.
To avoid overloading during startup and damaging machine components.

Start the extrusion, add small amounts of material and maintain a balanced feed.
Pay close attention to various table values such as torque when feeding.
After the material is extruded from the mold, the traction device pulls it to gradually increase the amount of material until it is extruded normally.

Keep the distance between the shaping mold and the die head.

Finally, when pulling, there should be a certain distance between the shaping mold and the die head to facilitate pulling and open the waterway. Be careful not to pour water into the die head, otherwise it will cause abnormal material discharge from the die head, causing the material to break or block the mold.
The shape is complex. For multi-cavity profiles, open the shaping mold cover.
The extruded material is plasticized normally and placed on the tractor.

Shorten the distance between the shaping table and the mold head, close the lid, and start the vacuum pump.
When the extrusion and pulling speeds are basically balanced, observe the outline until normal extrusion, and then reduce the distance between the shaping table and the die head.
