How to clean the dirt in the water channel of the preform mold?
1. Mechanical cleaning method
Checking the cooled-water channel: First, inspect the cooled-water channel and inlet and outlet nozzle to remove obstructions and scale etc. If necessary, use diluted hydrochloric acid to etch the water channel, then use an air compressor to blow away impurities, and perform a water pressure test to ensure that the water channel is unobstructed and leak-free.
2. Mold water channel cleaning machine
High-efficiency cleaning: Use the mold water channel cleaning machine to mix high-compressed air into high-speed water flow, and the bubbled compressed air and high-speed water flow act together on the mold cooled water channel to effectively remove attachments and corrosive substances, achieving fast and thorough cleaning.
Cleaning features:
Powerful cleaning: Powerfully clean the inside of the mold piping to prevent problems caused by rust, scale, etc.
Flexible use: It can be connected when the mold is replaced, or it can be cleaned separately when the mold is not in use.
Stable quality: After cleaning, the thermal conductivity is stable, which helps mold temperature management, improves production efficiency, shortens the molding cycle, and saves energy.
Extended life: The inner wall of the piping is solidified to prevent corrosion, thereby extending the service life of the mold.
3. Precautions
During the cleaning process, ensure that the cleaning agent does not corrode the waterway to avoid mold and machine damage.
The wastewater after cleaning should be properly handled to ensure compliance with environmental protection requirements and reduce the cost of treating the wastes.
Cleaning operations should be performed regularly to keep the mold waterway clean and unobstructed to ensure product quality and production efficiency.
The above method can effectively clean the dirt in the preform mold waterway to ensure the normal operation of the mold and the good quality of the product.
