A multi-cavity PET preform mould is a versatile tool used in the production of plastic bottles. It is made of stainless steel and is available in one to eight cavities. It can also be found in 16-cavity and 24-cavity versions. The plate is made of S136 stainless steel, which is anticorrosive and strong. The two halves of the PET preform mold are assembled with guide pins. The two halves of the mould form the entire tool.
A multi-cavity PET preform mould is generally made of hard steel and is multi-cavity in shape. It uses the hot runner system to create the plastic preform. Its design determines the quality of the mould, and the hot runner system is important in ensuring the quality of the finished product. This type of thermocouple ensures that the temperature of each cavity is controlled independently. A valve-gated design also avoids the white drawbench at the bottom of the mold, which increases labor productivity.
Another characteristic of a PET preform mould is that it is highly durable. The material used to build these devices is generally hard steel or aluminum. A multi-cavity PET preform mould is designed to last for several decades. The quality is guaranteed by the material used in the mold. The materials for a multi-cavity mould include aluminum, copper, and stainless steel. A high-quality polymer is needed for a high-quality product.
The design of a multi-cavity PET preform mould is crucial for a successful production. A properly designed plastics PET preform mould will have features such as means to eject the finished casting and temperature control. It will also need to be equipped with finishing tools, such as a drill jig, buffing attachments, holding fixtures, and gages. Using a single-cavity PET preform mould is ideal for production of plastic bottles, but it may be difficult to use if you want a different design.
A multi-cavity PET preform mould will have 72 cavities. It is constructed from Sweden special mold steel. The mold's cavity and core are made from imported nitrided steel, which is resistant to chemical and mechanical wear. The valve gated type will reduce labor force. Finally, a well-made PET preform mould will be polished to give a good finish and allow the casting to be easily ejected.
A multi-cavity PET preform mould uses a hot runner system to produce PET plastic. This system has a hot runner and a cold runner system. Each cavity will have a different temperature, which is important for the production process. This way, the mold is more reliable and durable, while avoiding the need for additional equipment. The cold runner system is essential for the production of mirror products.
