How to maintain the injection mold effectively

How to maintain the injection mold effectively? Generally speaking, the mold cannot be rusted. If rust is found, use a grinder for grinding and polishing. If there is water and dirt in the cooling channel, the channel needs to be cleaned. If the dirt is difficult to remove, please use copper rod, copper wire and professional mold cleaning agent to remove the dirt in the mold, or residual injection molding and other residues. Maintenance is not something that happens overnight, it is something that must be standardized and implemented.





First of all, the company should equip each mold with a resume card to record and count its use, care and damage in detail. Based on these data, we can find out which parts and components are damaged and the degree of wear, so as to provide information for finding and solving problems, as well as the molding process parameters of the mold and the materials used in the product, so as to shorten the trial run time of the mold and improve production efficiency.


Generally speaking, as the production time continues, the cooling channel is prone to deposit scale, rust, silt and algae, etc., which makes the cross section of the cooling channel smaller and the cooling channel narrower, greatly reducing the heat exchange rate between the cooling liquid and the mold, and further increasing The production cost of the enterprise, so the cleaning of the runner should be paid attention to. This is especially important for enterprises. For hot runner molds, the maintenance of the heating and control system is especially important to prevent production failures.


In this way, band heaters, rod heaters, heating probes, thermocouples, etc. on the mold should be measured with an ohmmeter after each production cycle. If there is any damage found in the inspection, it should be replaced in time, and compared with the mold resume, and a record should be made so that problems can be found in time and countermeasures can be taken. It would be best if no problems were found.


Injection molding is a delicate matter. So the maintenance work is more delicate. The above also explains how to solve problems such as mold rust. How to avoid the accumulation of dirt, causing narrowing of the cooling channels. Maintenance of the heater after production. Injection molds can only prolong their service life if they are effectively maintained.
