Compounding Equipment

Check Machine And Lubricate
Before starting the compounding extruder, check whether there is any foreign matter in the barrel, up and down the hopper, and inside, check whether the fastening bolts of each part are loose, whether the safety cover is firm, whether the position of each button switch is correct, and then lubricate each part. Add enough lubricating oil and do a good job of cleaning and sanitizing the equipment.

Temperature Control Testing
Before starting the machine, check whether the temperature control is sensitive, whether the instrument is out of order, and whether the cooling water circuit is smooth. Usually, methods such as thermometers and cooling water are used for detection.

Heating Step
Follow the compounding extruder operating procedures to heat the screw, barrel, and die head. Once reaching the set temperature, maintain warmth for about 10 minutes before starting the machine to ensure temperature stability in all parts.

Notify Staff Before Starting
Alert nearby staff when preparing to start the machine. Before starting, ensure all connecting screws and bolts of the die are tightened while it’s hot. Operators must avoid standing in front of the die before material extrusion to prevent injury from potential bolt or screw breakage.

Low-Speed Starting Motor
Start the motor for driving the screw rotation at low speed, and check whether the pointer of the working ammeter of the main motor swings normally.

Trial Run
The test run of the screw should not exceed 30 minutes. Once everything is normal, connect the die head and pelletizing equipment. Install the die head bolts and apply molybdenum disulfide or silicone oil to facilitate disassembly.

Initial Input
In the initial stage of feeding production, the screw should use the lowest working speed, and the feeding should be less and uniform. Check whether the pointer of the working ammeter of the motor used to drive the screw rotation changes at any time.

Temperature Checks During Production
During regular production, monitor bearing temperatures on the extruder. Use the back of your finger to touch motor and bearing parts for temperature checks gently. Avoid touching rotating parts during equipment operation.

Precautions For Disassembly And Assembly
When dismantling and installing the screw and mold, do not directly hit the parts with a heavy hammer, if necessary, pad hardwood and then tap to disassemble or install.

Clean Up Residue
Clean residual material from the screw, barrel, and mold with bamboo or copper knives, brushes, or specialized water and air washing equipment. Avoid using steel knives or fire. Alternatively, use special screw cleaning materials for cleaning without disassembly.
