Product Description

Taizhou Huangyan Xiong Shi Plastic Mould is located in Taizhou,China since 2009. We focus on injection mould of plastic packages,including PET preform moulds and various plastic cap moulds.After decade years effort, It has steadily developed into a modern enterprise specialized in manufacturing various specification of PET Preform mold and cap mould. With reasonable price, reliable quality and excellent service, we highly praised at home and abroad customers. Products are exported to Russia,Australia,Egypt,Ethiopia,Bangladesh, India, Malaysia,Cambodia and other countries and regions. Its widely used in the water,beverage,edible oil, food, cosmetics,washing supplies and other packaging industry, etc. The company inherits the responsibility throughout all the time, the quality originates from the responsibility idea to create the valve for the customer, everything starts from the production details.
 

§ Hot runner system for PET Preform Mould

There are two different types hot runner widely used for preform moulds - valve gated hot runner and thermally gated hot runner. 
Thermally gated hot runner use rod heaters and rod heaters were pluged into mold from one side to another side. In order to easily assemble and maintain heaters, often there is no cover on the mold heaters insert side. So we can see the heaters and wires from preform mold one side. Thermally gated hot runner temperature controller one zone control one rod heater. With this reason thermally gated hot runner temperature controller have less controller zones compare with valved gated hot runner temperature controller.Valved gated hot runner use ring heaters and contain one manifold plate.  We only can see the hot runner socket on the mold. Valved gated hot runner preform every heater need to be controlled by sperated temperature controller zone. Compare with thermally gated hot runner temperature controller, valved gated hot runner temperature controller have more controller zones.

§ Type of gate vestige

There are total three types of gate vestige for different hot runner gate preforms - long length vestige, short length vestige and flat little length vestige.The vestige difference is caused by the different hot runner nozzle design. Long length vestige preform hot runner nozzel without heater or very little length heater.  So the gestige length is very long. Need to use preform gestige cutting machine to trim the preform, then can go on the strech blow molding with these preforms.

There are two ways to separate the hot melt coming through the hot run-ner from the cooled preform: thermal and mechanical. Thermally gated hot runners are most prevalent in one-stage while it is the other way around in two-stage injection molding.In a thermally gated hot runner the break point between the hot and cold melts is controlled by temperature alone. As seen in above picture the tempera-ture difference between the cold cavity and the hot melt is substantial at around 255°C (491°F). A suitable insulation made from stainless steel or other material with insulating properties separates the two sections. When the machine ejects the preforms the melt breaks at the point where thecold gate vestige connects with the hotter material inside the nozzle. This material is already partly cooled down and so has a higher than melt vis-cosity. This prevents it from seeping into the cavity or lead to "stringing,"a common defect where small strands of PET from the melt stream are pulled out with the preform during ejection. An air gap may also assist in the separation process.

From the peform sample, we can see clearly the difference between hot runner valve gate and thermally gate. Left one with short tail, the preform mold is with thermally gate, the right one with flat/shut off tail, the preform mold is with valve gate.
