Description

Gutewei is a professional manufacturer dedicated to producing high-performance PET preform molds for the global bottling industry. Our 48 Cavity PET Preform Mold is designed to deliver reliable, repeatable results for medium-volume production runs, helping you maintain competitive advantage in today's packaging market.

This mold represents the ideal solution for businesses seeking to optimize their production floor with equipment that balances efficiency, durability, and ease of operation.

Technical Excellence:

Precision Cavity Machining
Each cavity is precision-machined using advanced CNC equipment, ensuring exact dimensional accuracy and perfect preform geometry. This attention to detail results in consistent wall thickness distribution and flawless neck finishes across all 48 cavities.

Superior Material Selection
We utilize only premium steel grades including S136, 2738, and 2311, with comprehensive heat treatment processes that achieve optimal hardness and wear resistance. This material strategy ensures your mold maintains its precision through extended production campaigns.

Engineered Cooling Performance
Our cooling system design incorporates computational fluid dynamics analysis to create optimal flow paths around each cavity. The result is uniform heat extraction that minimizes cycle times while preventing common quality issues such as haze, crystallization, or dimensional variation.

Practical Maintenance Features
Quick-change cavity and core inserts allow your maintenance team to perform replacements or cleaning procedures with minimal effort. This design philosophy reduces downtime and keeps your production schedule on track.

We exclusively use premium corrosion-resistant stainless steels such as Assab S136 (Sweden) and Groditz M340 (Germany). Combined with deep vacuum nitriding, surface hardness exceeds HV1000°, with mirror polishing up to Ra≤0.015μm. We guarantee a mold life of over 3 million shots.
Standardized with our in-house developed pneumatic valve gate hot runner system. Multi-zone independent temperature control keeps fluctuation ≤±1℃, preventing material degradation. The gate is automatically sealed after injection, creating a "gate-cut-free" preform that requires no manual trimming — achieving true zero-waste production.
Our 3D conformal cooling channels, designed based on ANSYS simulation, eliminate hot spots and increase cooling efficiency by over 30%. By optimizing the mold structure and injection process, we achieve an injection cycle time of under 10 seconds, significantly boosting your production capacity.
Perfectly compatible with major global injection molding machine brands: HUSKY, NETSTAL, SACMI, KRONES, DEMAG, and all major Chinese manufacturers. Standard interface design for plug-and-play operation.
