72 cavity hot runner plastic pet preform mold
Usually, Multi-cavity pet preform mould does use the hot runner system rather than cold runner system, so the design of hot runner system plays an important role in mould quality guarantee. Based on foreign advanced techniques and combined with domestic clients’ demand, we adopt the valve gated design, in which each cavity has its own heating zone and temperature is measured by independent thermocouple.(advantages: easily avoid some problems such as white or drawbench on bottom). Here, Mould is produced automatically to reduce labor force.
The main components of moulds ( die core, die cavity and screw neck) are made by injection process, which are made of special mold steel ( Germany steel 2316) after preheating treatment in the original factory in Germany. In this way, the mould with long life service and high quality can be used for 2 million shots without any maintenance, meanwhile, the wall thickness between max. parts and min. part is not more than 0.10mm. We adopt mould base of 50# steel and sliding block of 718# steel. And the moulds equipped with imported components including high-qualitied lubricating copper plate, Germany heaters HOTSET, Germany standard PID temperature controller. Moreover, turning center processes make sure that every parts can match well; proper distribution of cooling water way improve productivity effect and molding cycle only takes 15 seconds( need proper water chiller, bottle design and injection machine).
Our mould, designed and developed by our engineers, is of high precision and long life span without traditional problems. In a word, Preform wall thickness is on error of 0.10mm; weight difference is less than 0.3g; 2-5 moulds per minute; 2 million guarantee; utmost 96 cavities in one mould.
-Customized material 632:Better than FS136, with higher nickel and chromium contents.
-Toughness, rust resistance, brightness effects are increased significantly.
-Mould base is made of stainless steel or P20（Preharden）with HRC 38~40.
