How to Design a PET Preform Mould

If you want to know how to design a PET preform mould, then read this article. In this article, we will discuss the Valve gate system, Temperature control, and Design of a PET preform mould. By the end of this article, you should be able to create your own mould in no time. This is the first step in designing a PET preform mould. Here are some tips:

A PET preform mould has several important features. Its functional strength and sales appeal are critical to its success. Its price and processability are also critical to its success. The best materials for a PET preform mould are high-grade steels and specially processed water channels. The mould's overall cycle time is greatly reduced and it minimizes the chances of jamming.

Indian PETform has developed advanced preform moulds with hot-runner systems up to 144 cavities. At K2019, the company demonstrated a new hot-runner development for preform moulds. The new mould's improved insulation makes it possible to reduce energy consumption by as much as 15-20%. Advanced insulation materials, such as titanium or ceramics, also decrease the amount of NG generated. Ceramics and titanium, on the other hand, have very low thermal conductivity and can be used in PET preform moulds.

In general, a PET preform mould is installed using a hot-runner system. To be efficient, a PET preform mould should feature insulating plates that are at least 12 mm thick and able to handle a high pressure. It should also be equipped with enough air venting to prevent overheating in certain parts of the mould. The slot depth should not exceed 0.03mm, as too thin a depth will invite flash.

An integrated valve gate system ensures the best forming of PET preforms and also keeps the operating window as wide as possible. It also provides the least amount of stress to the PET preform. The valve gate system requires a larger mould and a hot runner to offset the operating mechanism. However, it can usually fit within the mould without significantly increasing its footprint. A valve gate is ideal for high-volume production, as it reduces labor and material costs.

Depending on the mold design, there are many types of valve gates. Some are mechanical, while others are pneumatic. For single and multi-cavity molding, the SV series includes a valve gate with a temperature controller and an air source in the factory. A tip heater is also available for reinforced resins. The valves are designed to accommodate a variety of molding processes and can be made with a large range of gate sizes, including small pitch 25mm.
