Description

GUTEWEI MOULD

24-Cavity PET Preform Mold for CSD Bottles

High-Precision, Heavy-Duty Injection Solutions for Carbonated Soft Drink Packaging

The 24-Cavity PET Preform Mold for CSD (Carbonated Soft Drink) Bottles by GUTEWEI MOULD is engineered to withstand the rigorous demands of high-pressure beverage packaging. Carbonated beverages mandate exceptional base-structure uniformity and tight dimensional tolerances to accommodate post-blowing gas pressures. Our specialized 24-cavity tooling offers the ideal equilibrium between manufacturing agility, optimal cooling metrics, and long-term capital investment return.

Core Engineering & Performance Features

1. Optimized For High Internal Pressure (CSD Performance)

CSD preforms require strategic material distribution, particularly around the gate area and bottom radius, to prevent stress cracking or deformation under carbonation pressure. GUTEWEI utilizes advanced CAD/CAE simulation software to refine preform wall thicknesses, ensuring excellent stress distribution during downstream stretch blow molding.

2. Advanced Pneumatic Valve Gate Hot Runner

Our balanced hot runner layout guarantees identical thermal conditions and melt delivery speed to all 24 cavities. The pneumatic valve gate pins provide positive mechanical shutoff, entirely eliminating problematic tailing, stringing, and crystalline gate defects that weaken bottle bases.

Technological Advantage: Zero Dead-Leg Channel Design

The hot runner manifold features smooth, radial sweeping paths with zero stagnant zones. This effectively suppresses thermal degradation, keeping Acetaldehyde (AA) generation to an absolute minimum to retain beverage flavor purity.

3. Double-Axial Independent Cooling Channels

To achieve high efficiency and rapid cycle times, the mold utilizes a multi-circuit cooling matrix. Each core insert features an internal cooling spiral tube, while cavities are wrapped in independent cooling sleeves. This maximizes heat transfer, shortens solidification times, and prevents core bending or preform ovality.

4. Inter-Changeable Interlocking Core-Cavity Architecture

Taper Alignment Positioning: Double-taper locking mechanisms ensure precise concentricity alignment, preventing uneven wall thickness defects.
Modular Component Design: Core and cavity inserts can be replaced easily in the field without modifying the main mold plate, drastically reducing downtime during weight conversions.
Corrosion-Resistant Base: Stainless steel mold base construction resists ambient humidity and condensation from chilled water systems.

Downstream Automation Integration

The GUTEWEI 24-cavity tooling is fully compatible with standard international injection molding machinery and automated take-out robots. The stripper plates and ejector pins are calibrated for smooth mechanical release, ensuring clean hand-offs to EOAT (End-of-Arm Tooling) cooling plates for rapid part cycling.

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.
