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. Preform mold cavities distance reduction.
This can reduce the preform molding cycle time by 10 seconds. In order to reduce the PET preform molding cycle time, SINOPK optimized the cooling system of the preform mold and in the same time, we designed one special vice cavities which can make the preform cooling in outside of the mould.
Preform molding researching for reducing the cycle time.It is because we know how, and we do what should be done. By offering the top quality solutions of PET Preform molding and various plastic cap molding to the market, SINOPK has won high praise from the market. Constant technological improvement, technological innovation on preform molding makes SINOPK the industry leader in PET Preform Mold and cap closure mold manufacturing.
