High-Efficiency 48 Cavity PET Preform Mould Features

High-Precision Mold Manufacturing Process, Laying a Solid Foundation for Product Quality

Adopting industry-leading high-precision mold manufacturing processes, we integrate core technologies such as CNC precision milling, EDM, and WEDM. Combined with high-precision testing equipment including Coordinate Measuring Machines and laser interferometers, we achieve micron-level machining precision control for mold cavities, cores, and other key components. Precise mold processing not only ensures that key indicators of PET preforms—such as mouth size, wall thickness uniformity, and weight deviation—meet the top industry standards, but also guarantees the dimensional consistency of each preform during mass production. It fundamentally avoids quality issues such as mouth deformation and uneven bottle wall thickness in the subsequent blow molding process, fully meeting the high-quality and high-consistency production requirements of PET preforms in fields such as food, beverage, and pharmaceutical packaging.

High-Efficiency 48 Cavity PET Preform Mould Features

Wear-Resistant Premium Base Material, Extended Mold Service Life

Key mold components adopt internationally sourced high-grade mold steel. After precision heat treatments including vacuum quenching, cryogenic treatment and nitriding, the surface hardness reaches HRC52–58. Combined with premium Oerlikon Balzers coating, the mold delivers greatly enhanced wear resistance, corrosion resistance and demolding performance.
It withstands long-term high-speed continuous production, effectively resisting melt erosion and thermal shock. The mold is resistant to abrasion, galling and oxidation, maintaining stable durability under high-output working conditions and significantly reducing the full-lifecycle maintenance cost.

FAQ

 

 

Q: What kind of production needs is the 48-cavity PET preform mold suitable for?

A: The 48-cavity mold is mainly suitable for preform production scenarios with medium to high capacity requirements. It can significantly improve the output per unit time while ensuring stability, making it ideal for customers in beverage, food, and daily chemical packaging industries that have demands for mass production. Compared with low-cavity molds, it achieves a good balance between production capacity and investment cost.

Q: How to ensure the dimensional consistency and product stability of the 48-cavity mold?

A: We ensure the consistency of each cavity through high-precision CNC machining and strict assembly tolerance control. At the same time, we optimize the design of the hot runner system and cooling system to achieve uniform melt distribution, avoiding flow deflection or local overheating, thus ensuring the high consistency of preform weight, wall thickness and caliber.

Q: What are the advantages of the hot runner system of the 48-cavity mold?

A: The adoption of an efficient hot runner system can realize cold-free production, reduce raw material waste, and improve the stability of the molding cycle. At the same time, the precise temperature control system can ensure uniform feeding of each cavity, reducing product defect rate from the source and improving overall production efficiency.

Q: What is the general service life of the mold? How to extend its service life?

A: Under normal maintenance and standard operation conditions, the 48-cavity mold can achieve millions of injection molding cycles. The service life of the mold can be effectively extended and the maintenance cost can be reduced by selecting high-hardness wear-resistant steel, optimizing the cooling design, and conducting regular maintenance (such as cleaning, lubrication and inspection of key components).

Q: Does SZ-MOLDTECH support the customized design of 48-cavity molds?

A: We can provide customized mold design solutions according to the customer's bottle structure, bottle mouth standard, injection molding machine parameters and production capacity requirements, including cavity layout optimization, hot runner brand selection and cooling system design, to ensure that the mold is highly matched with the production line.

Q: What are the requirements for the injection molding machine for the 48-cavity mold?

A: The 48-cavity mold usually needs to be matched with a medium to high-tonnage injection molding machine, and has certain requirements for injection pressure, clamping force and plasticizing capacity. We will evaluate according to the customer's existing equipment parameters and provide matching suggestions to ensure that the mold can operate stably and exert its best performance.
