In the process of processing plastic molds, relevant manufacturers will design in advance, try to think of the problems they will encounter, and think of countermeasures in advance. However, there are some inconsistencies between the specific operation conditions and the design, and it is inevitable to encounter large and small problems. When making molds, it doesn't matter if you encounter difficulties. Find a solution immediately to recover the loss.

I do n’t know if the processing plastic mold manufacturers have encountered cooling water leakage? When such a problem occurs, you should find the cause and then look for a solution.


There may be a problem at the cooling water pipe joint. Such a problem is most likely to occur in this part. It is recommended that manufacturers of processed plastic molds check it. If you find that the cooling water is leaking, you can use a sealing tape at the joint and tighten it again, which should solve this problem.


The waterproof ring may be damaged. When processing plastic molds during molding, there may be problems with the waterproof ring due to the fixed molding conditions. Once the waterproof ring hardens or cracks slowly, it will naturally leak. In addition, if the improper installation method of the waterproof ring may lead to a poor sealing effect. This requires manufacturers to regularly check to see if the waterproof ring is damaged, do you need to seal again?

There may be a problem with the wall of the cooling water hole. This situation will be encountered when trying out new molds. Once the design of the plastic mold is processed, there is an error in the wall thickness, which may cause water leakage. This requires manufacturers to operate in strict accordance with requirements to minimize errors.


There may be a problem with the cooling water holes. Scale will appear in the cooling water hole during long-term use, which is not conducive to the transfer of heat and may even cause blockage. How to do? The most direct way is to regularly check and repair the scale and rust, and do not delay the normal use of water holes. If it is a hidden cooling water pipe, the mold should be disassembled, and then the rust should be cleaned up.


After completing the overhaul, try again and it will not leak. Professionals who process plastic molds know how to pass tests to test, and they will also get more professional results. If there is still water leakage, you can use elastic material to block.


There may be a problem with the heating tube or the pressure reducing pump. In the process of manufacturing plastic molds, the function of the heating tube is to transfer heat, which can quickly cool the core. For the place where the cooling water passes, it can be properly heated to reduce the chance of water leakage. In addition, the pressure-reducing pump can absorb the cooling water, and this little technique is worth adopting.


Don't underestimate some minor problems in the process of processing plastic molds. Once the cooling water leaks continuously, it will not be handled correctly, which will cause a lot of trouble. For a mold, if it can't be cooled in time, it can't complete the demoulding, and naturally it can't produce the mold with good quality and quantity.


The above-mentioned factors may be the main reason for the leakage of cooling water, and more attention can be paid during the processing of plastic molds. Once it is found that the cooling water has leaked, you can find the reason from the above aspects. Of course, experienced manufacturers will not affect their work because of cooling water leakage, and will carry out repairs and maintenance in advance to minimize the chance of failure. Regular inspections will not delay work efficiency.
