What are the key factors to consider when selecting a 12-cavity PET preform mold for high-volume production?

PET preform molds are essential tools for producing high-quality PET bottles, and selecting the right mold is crucial for achieving high productivity, quality, and efficiency. Here are some of the key factors to consider when selecting a 12-cavity PET preform mold for high-volume production:

Material and Hardness: The core and cavity material and hardness are critical to the mold's durability, resistance to wear and tear, and ability to produce consistent preforms. Materials such as S136 and ASSAB S136 are commonly used in high-volume production due to their superior hardness, toughness, and corrosion resistance.

Injection and Ejection System: The injection and ejection system is critical to the mold's efficiency and consistency. Short-tail, long-tail, and pin valve gates are commonly used to achieve consistent melt flow and reduce cycle time. Additionally, stripper plates or other ejection systems should be employed to ensure quick and reliable ejection of preforms.

Cavity Number: The number of cavities in a PET perform mold will affect the production capacity of the machine. A 12-cavity mold is ideal for high-volume production, as it can produce a large number of preforms per cycle, reducing production time and cost.

Delivery Time and Mould Lifetime: The delivery time for a PET preform mold is an important consideration for manufacturers who need to minimize downtime and maximize production. Additionally, the mold's lifetime is a critical factor, as a mold that is prone to wear and tear will lead to lower production capacity, increased costs, and reduced quality.

Warranty: The warranty period is an important factor when selecting a PET preform mold. A longer warranty period can offer peace of mind to manufacturers who are looking for a reliable, high-quality mold that will last for many production cycles.

In conclusion, selecting the right 12-cavity PET preform mold for high-volume production requires careful consideration of the material and hardness, injection and ejection system, cavity number, delivery time and mold lifetime, and warranty period. By considering these factors, manufacturers can find a mold that meets their production needs and delivers consistent, high-quality preforms.

12cavity PET Preform mould
The cavity No.: 12cavity and in general, it is for the production capacity is not so big. Because in general, the smallest cavity for lightweight PET preform mould we choose is: 8cavity. In this way, 12cavity PET preform mould is not so big and it can use the same size injection machine compared to the 8cavity. The arrangement for 12cavity plastic PET preform mold is: 6*2 and the width is the same as 8cavity PET preform mold but the capacity could be higher. So I advise you to choose 12cavity compared to the 8cavity PET preform mould. Also for preform mould, we also have PP preform mould, PC preform mould, Tritan preform mould. The 12 cavity PET preform injection mould can produce a mold with high efficiency, as it can drop preforms automatically. Thank you for your kind reading and new technology is updating.
