Common problems in injection molding

Release time:2022-01-10

Is there any special structure and special requirements for mold manufacturing? For example, the mold needs a manipulator to assemble and disassemble. If this problem is not considered in the mold acceptance process, it will certainly affect the installation and service life. This also shows that it is not enough to only focus on the mold, and the whole mold system must be considered comprehensively. For example: cavity pressure sensor, core pulling device, special mold heating and cooling method, environmental cleanliness, vertical mold, multi-point injection mold, manipulator and pickup device, part processing method, etc.


Are the raw materials general plastics or engineering plastics? in general. The process of processing engineering plastics is relatively complex, especially for inexperienced injection molding manufacturers. Special attention should be paid to that some parts processed with glass fiber or intensifier nylon may need oil to heat the mold, so as to avoid damage to the mold cavity or core caused by the migration of the surface of the parts caused by glass fiber. Next, we need to consider that the wear resistance and tear resistance of drying equipment, screws, barrels, check rings and other parts need to be improved.


How to determine the maintenance quality and service life of the mold? In terms of time, the service life of the mold is not a very important factor in the actual use of the mold, because in the use of the mold, we need to pay more attention to various design modes, manufacturing methods, various maintenance conditions and other factors of the mold. A set of new molds with low standards are usually made of low-quality steel, and the location of parting line scoring and ejection guide rail are not marked at the same time, so the designed molds are difficult to be used for injection molding for production and maintenance.
