Operating Cost Advantages

Compared with traditional injection molding machines, the Eone series offers several cost-saving benefits:

1. The fully automated system is highly intelligent. One machine delivers the output of two conventional machines, cutting labor costs by half.
2. Low energy consumption during production, saving over 35% compared to standard servo machines and more than 50% compared to non-servo traditional machines. Only 0.4 KWH per kilogram of preform.
3. High finished product rate. Ordinary machines have a rejection rate of 1.5%, but the Eone preform system boasts a pass rate of 99.7%.
4. Exceptional plasticizing effect and superior color mixing performance, ideal for producing high-quality preforms.

The production cost of each preform produced by the Eone series is significantly lower than that of traditional machines. For instance, in producing 15-gram water bottles with 48 cavities, the Eone (48/72) cavity preform system can save 0.009 yuan per preform. Over a year, based on 320 operational days and producing 143 million preforms, this can result in at least 1.28 million yuan of additional income for customers.
