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.
Main mould components (die core, die cavity, screw neck) are made by injection process, and the material of which originates from Sweden high-quality mould steel (HRC 45).In this way, it is no doubt that the mould can be used for 2 million shots without any maintenance, meanwhile, the wall thickness between max. part and min. part is not more than 0.10mm; 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 144 cavities in one mould.
Main feature: 1.Mold cavity from 1 up to 144. 2.Electric control system with simulating stretch testing improve yield rate. 3.Adopt world advanced dipole taper localization technique, each cavity self-clamp independently, ensure mould concentricity. 4.The material of mould die core and die cavity are made of Sweden special mould steel. 5.International standard screw neck, imported nitrided steel with high hardness is of long usage. 6.Advanced hot runner design and even heating temperature make sure the high quality of plastic products. 7.Valve gated type without tail reduces labor force. 8.At least 2 million guarantee.

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).

Main feature: 1.Mold cavity from 1 up to 96. 2.Electric control system with simulating stretch testing improve yield rate. 3.Adopt world advanced dipole taper localization technique, each cavity self-clamp independently, ensure mould concentricity. 4.The material of mould die core and die cavity are made of Sweden special mould steel. 5.International standard screw neck, imported nitrided steel with high hardness is of long usage. 6.Advanced hot runner design and even heating temperature make sure the high quality of plastic products. 7.Valve gated type without tail reduces labor force. 8.At least 2 million guarantee.
Preform Molds Preform molds are produced at dedicated facilities in China. Preform molds range up to 144 cavities and offer:
Productivity
1. Fast cycling due to specially designed cooling circuits 2. Part ejection sensors that monitor preform transfer to the take-off plate, improving cycle time 3. Standard interchangeable mold components; replacement parts available within 24 hours
Reliability
1. Rugged design for long life 2. Auxiliary tapers that reduce mold wear by pre-aligning the mold halves prior to the engagement of the neck ring tapers 3. Roller cams that actuate both the opening and closing actions on the thread splits
Part Quality
1. Lowest cavity-to-cavity weight and dimensional variation as a result of best-in-class manufacturing machines and processes 2. Water hoses that are manifolded at the bottom of the mold, eliminating potential for water marks on preforms
We can design and produce all kinds of cap moulds according to customers’ requirements.
After many years’ development and innovation, hot runner arts and crafts which is the most ideal in the line of the injection, is applied in making cap moulds. It reduces the product cost, raises the product quality, so it can produce automatically.
Hot Runner Cap Mould has following strongpoints: 1. With pneumtic valve gate system. 2. Optimal cooling design and all the cooling system are Nickel plated. 3. All the components can be interchangeable. 4. Mirror hand polidhing for the core and cavity. 5. Adopted temperature controller. Temperature of the cap is controlled point by point. 6. The material of corn and cavity are made of #2316 stainless steel. Other parts are made of #P20 steel.
