1. Descripción general del producto
Industrias aplicables: Juices, RTD teas, sports drinks, and any preservative-free hot-fill beverage manufacturing.
Resumen de las principales ventajas: Hot-fill liquids (85°C to 90°C) cause standard PET bottles to shrink and catastrophically deform. EVER POWER, originating from the Netherlands, architects highly specialized two-stage reheat stretch blow molding machines. Utilizing thermal crystallization technology and custom ribbed molds, we ensure your PET bottles possess absolute thermal stability to withstand hot-filling and the subsequent cooling vacuums.
2. Technical Parameters: Hot-Fill Series
| Parámetro | Rango de especificaciones |
|---|---|
| Filling Tolerance | Up to 90°C without deformation |
| Machine Output | Scalable from 1800 to 9200 BPH |
| Cavity Configuration | 2 to 8 Molds depending on model |
| Heating Elements | Extended Infrared Crystallization Ovens |
3. Working Principle & Crystallization
Creating a hot-fill bottle alters the standard two-stage process. Preforms undergo an extended thermal soak in the infrared oven, increasing the crystallinity of the PET polymer chains. Once inside the blow mold, hot oil or specialized heating mediums circulate through the mold walls (rather than chilled water). This process “heat-sets” the plastic, erasing thermal memory. The biaxially stretched bottle is now physically immune to shrinking when 90°C liquid is poured into it.
4. Ventajas principales
🔥 Extreme Heat Tolerance
Biaxial crystallization ensures bottles maintain complete structural integrity up to 90°C.
🌪️ Vacuum Resistance
Custom aluminum molds impart specialized ribbing to absorb the vacuum generated when the hot liquid cools.
⏱️ High-Speed Output
Despite the complex heat-setting, our robust mechanics ensure up to 9200 BPH for mass commercial production.
♻️ Air Recovery Standard
Captures high-pressure exhaust to feed mechanical cylinders, offsetting the energy costs of hot-filling.
🤖 Simple Integration
Designed to sit directly upstream of hot-fill liquid carousels for seamless turnkey operations.
5. Estructura y tecnología de materiales
EVER POWER hot-fill machines are heavily fortified. The chassis is welded from thermal-resistant alloy steel to handle elevated radiant heat. Most crucially, our CNC aluminum blow molds are engineered with highly sophisticated fluid channels. These channels circulate hot thermal oil to achieve the vital “heat-set” crystallization phase before ejection.
6. Aplicaciones típicas
Preservative-Free Juices
Requiring pasteurization temperatures during filling to ensure long shelf life without chemicals.
RTD Teas & Sports Drinks
Hot-filled to maintain absolute sterility, requiring specialized vacuum-absorbing bottle paneling.
7. Guía de selección
Hot-fill requires more than just a machine; it requires a specialized preform and mold design. Ensure you consult our engineers about your exact liquid temperature. You will also need to size your auxiliary equipment properly—hot-fill requires thermal oil heaters alongside standard high-pressure air compressors.

11. Preguntas frecuentes
Do I need a special preform for hot-filling?
Yes, you typically need a higher-weight preform with a crystallized neck finish to prevent the threads from deforming during hot capping.
