Customized PET Preform Molds: Precision Solutions for Every Production Scale

APEX Machinery proudly presents our comprehensive range of Customized PET Preform Molds—precision-engineered tooling solutions designed to meet the diverse needs of preform manufacturers at every production scale. From small-scale specialty production to high-volume mass manufacturing, our molds deliver exceptional quality, consistency, and longevity. With cavity configurations ranging from 1 to 72 cavities and beyond, we provide tailored solutions that optimize your production efficiency and product quality.

Complete Cavity Range for Every Production Requirement

APEX Machinery offers PET preform molds in a wide spectrum of cavity configurations to match your specific production needs :

Each cavity configuration is engineered to deliver optimal performance for its intended production volume, ensuring that you never over-invest in capacity you don't need or under-size for your market demands.

Advanced Mold Technology for Superior Preform Quality

Our customized PET preform molds incorporate cutting-edge technologies that ensure exceptional preform quality:

1. Precision Valve Gate Hot Runner Systems
Our molds feature advanced pneumatic needle valve gate hot runner systems with individual temperature control for each nozzle . This ensures balanced filling across all cavities, eliminates common defects such as bottom whitening or drawdown, and maintains consistent preform quality throughout production runs. The valve gate technology provides clean gate vestige and reduces material waste .

2. Optimized Cooling System Design
Efficient cooling is critical for reducing cycle times and maintaining preform dimensional stability. APEX molds incorporate:

• Spiral cooling channels in cavity inserts for rapid, uniform heat extraction 

• Fountain flow or spiral cooling in core inserts ensuring consistent cooling of the preform interior 

• Dedicated cooling circuits for neck rings, recognizing that the neck finish area contains the thickest material section 

• Cross-drilled cooling channels in neck rings for optimal temperature control 

This advanced cooling architecture enables faster cycle times while maintaining excellent preform quality and dimensional stability.

3. High-Quality Materials for Extended Mold Life
APEX molds are constructed from premium materials selected for durability and performance :

• Mold plates: P20 or 4Cr13 pre-hardened steel for structural integrity

• Core and cavity inserts: S136, FS136, or Swedish pre-hardened mold steel with superior corrosion resistance and wear characteristics

• Neck rings: Nitrided steel for exceptional wear resistance in the critical thread-forming area

• Hot runner components: H13 tool steel with heating elements from global leaders like Rotfil (Italy) and Hotset (Germany) 

With proper operation and maintenance, our molds deliver over 2 million injection cycles with consistent performance .

Comprehensive Neck Finish Options

Our customized PET preform molds accommodate a wide range of industry-standard neck finishes to ensure compatibility with your closure requirements :

• PCO finishes: PCO 1810, PCO 1881 for carbonated soft drinks and water bottles

• BPF finishes: 30/25, 29/25, 26/22 for European and international applications

• ROPP and ALASKA finishes: For roll-on pilfer-proof closures

• Wide mouth finishes: 38mm, 48mm, and up to 150mm for jars and wide-mouth containers 

• Custom neck designs: Tailored solutions for specific closure requirements

Precision Engineering for Consistent Quality

APEX molds are manufactured with precision that ensures exceptional preform quality:

• Weight variation between cavities: Maintained below 0.3 grams, ensuring consistent preform quality for downstream blow molding 

• Excellent concentricity: Between core and cavity minimizes wall thickness variation, ensuring uniform material distribution in final blown bottles 

• Low acetaldehyde (AA) content: Optimized hot runner design minimizes material degradation and AA generation 

• Superior surface finish: Eliminates weld lines and ensures preform clarity 

Compatibility with Leading Injection Molding Machines

Our customized PET preform molds are designed for compatibility with all major injection molding machine brands :

• Global leaders: Husky, Netstal, KATA

• European manufacturers: SIDEL, KRONES, SIPA, SIG, ASB

• General PET injection machines: Compatible with standard machine interfaces

We provide molds configured specifically for your existing equipment, ensuring seamless integration into your production line.

1-16 Cavity Molds: Flexibility for Specialty Production

Our smaller cavity molds (1-16 cavities) are ideal for :

• Prototype development: Testing new preform designs before committing to high-cavitation production

• Specialty preforms: Low-volume runs for niche products or seasonal packaging

• Market entry: Companies establishing their presence with limited initial volume

• Wide-mouth containers: Larger preforms requiring fewer cavities due to size 

The 16-cavity configuration, in particular, offers an excellent balance of efficiency and flexibility for growing operations .

24 and 26 Cavity Molds: Balanced Mid-Volume Production

Our 24 and 26 cavity molds serve manufacturers with established market presence requiring consistent, reliable output . These configurations offer:

• Efficient production rates suitable for regional distribution

• Flexibility to handle multiple preform specifications

• Lower initial investment compared to higher cavitation systems

• Simplified maintenance and faster changeovers

32 Cavity Molds: The Versatile Workhorse

The 32-cavity configuration represents one of the most popular choices in the industry, offering :

• Excellent production efficiency for mid-to-high volume requirements

• Proven reliability with decades of industry acceptance

• Balanced tooling costs and per-part economics

• Compatibility with a wide range of injection molding machine sizes

48 Cavity Molds: High-Volume Production Excellence

Our 48-cavity molds are engineered for manufacturers requiring substantial daily output :

• Typical layout: 4 × 12 cavity arrangement with two-stage double taper positioning 

• Each cavity independently self-locking ensuring concentricity and consistent quality 

• Production rates of 17,000 to 25,000 preforms per hour depending on preform weight
