Maintenance and care of silicone casting machine after shutdown

Maintenance and care of silicone casting machine after shutdown
1. Equipment cleaning
Material residue treatment:
If single-component silicone is used, flush the pipes and nozzles with alcohol or special cleaning agent after shutdown (10-15 minutes) to ensure that there is no material residue;
Two-component silicone needs to discharge the remaining materials in the A and B barrels first, and then clean them with corresponding solvents (such as acetone for curing agent components).
Parts disassembly and cleaning: Regularly (weekly) disassemble the nozzle and filter, and clean them with an ultrasonic cleaner (water temperature 40-50℃, time 15 minutes) to remove curing residues.
2. Status inspection and record
Check whether the piston pump and sealing ring are worn (if leakage occurs, they need to be replaced in time), and whether the gap between the screw and the pump body of the screw pump is within the standard range (usually 0.1-0.3mm).
Fill in the operation record (including start-up time, material consumption, parameter settings, abnormal conditions and treatment measures) for subsequent traceability and maintenance.
