SINOPK has solved most of the components can be changed on the molding machine, in this way, we avoid preform molding production time losing and keep the maintenance become very convenient. This will cost a lot of time and also very complex and dangerous. ![]() In the old design, the preform molding has to be stopped and we have to release the preform mold from the molding machine to disassemble it for components changing. When preform molding process, sometime, if there is any cavities, cores or preform mold other components was damaged. In order to use smaller tonnage of the preform molding machine to approach biggest economical production, SINOPK made the cavities distance as small as possible, this is not only reduced the preform molding machine size, also reduce the PET material heating and melting time to improve the preform molding quality, this improved the bottle blowing quality.
