Product Description

The EC500-IIIS/4210-PET is a high-performance electric melt injection molding machine specifically engineered for the production of high-quality PET preforms used in bottle blowing lines. With a clamping force of 5,000 KN and a large platen size, this machine is designed for 64‑96 cavity molds, delivering exceptional output efficiency. Its specialized PET screw and barrel (38CrMoAlA) ensures uniform plasticization and melt quality, essential for producing consistent preforms with excellent clarity and dimensional stability.

This injection molding machine is the ideal upstream solution for large-scale bottled water and beverage plants, where a stable, high-volume supply of preforms is critical to keep downstream blow molders running at full capacity. The EC500-IIIS is available in several configurations to suit different preform weights and production targets. It also supports a wide range of preform neck types, including the 3025 standard neck commonly used in 5-gallon bottled water applications.

The EC500-IIIS leverages advanced electric melt technology to provide faster injection speeds, precise shot control, and superior energy efficiency over traditional hydraulic machines. It is equipped with premium brand components including YUKEN valves, FIRST motors, SCHNEIDER electrics, LEUZE sensors, GEFRAN pressure sensors, and MODROL servo drives.

Key Features

1. High Clamping Force (5,000 KN)
The large clamping unit provides stable, reliable clamping even for multi-cavity molds (64 to 96 cavities). This ensures consistent part quality, minimizes flash, and extends mold life.

2. Large Platen & Wide Tie Bar Distance (840×800mm)
The generous platen size accommodates large, complex molds, enabling higher cavity counts and lower per-unit cycle times.

3. Specialized PET Screw & Barrel
Constructed from 38CrMoAlA with high wear resistance, the PET-dedicated screw and barrel ensure excellent plasticization, consistent melt quality, and long service life, even for recycled PET materials.

4. High Injection Speed & Pressure
With an injection rate of 1,109 g/s and a maximum injection pressure of 151 MPa, the EC500-IIIS ensures fast fill times, high output, and consistent preform quality across all cavities.

5. Advanced Electric Melt Technology
The electric melt system offers precise temperature control and energy savings compared to conventional hydraulic systems. The servo-driven design reduces power consumption, improves repeatability, and enhances overall machine stability.

6. Premium Components & Reliability
All key components are sourced from world-class brands:

Hydraulic valves: YUKEN (Japan)

Servo motor & drive: MODROL (China)

Oil pump motor: FIRST (China)

PLC/HMI: EST (China)

Electrics: SCHNEIDER (France)

Sensors: LEUZE (Germany), GEFRAN (Italy)

Seals: HALLITE (England)

High-pressure hoses: AEROQUIP / Eaton (USA)

This ensures long machine life, low downtime, and excellent after-sales support.

7. Flexible Preform Weight & Cavity Configurations
The EC500-IIIS supports a range of preform weights (14g, 20g, 28g, 38g) with optimized cavity counts for each weight, allowing manufacturers to select the ideal configuration for their production needs.

Company Profile

Shine Dew Technology focuses on water, beverage, and packaging equipment projects, covering standalone machines, complete lines, engineering planning, and after-sales coordination. For products such as 5 Gallon ISB molding machines, our team supports solution matching from equipment selection to project delivery, helping customers reduce communication cost across procurement, installation, and production start-up.

We work with customers on equipment selection, line matching, technical communication, and follow-up service, so upstream bottle manufacturing can connect more smoothly with downstream washing, filling, capping, and packaging systems.
