Preform Injection Molding Machine Jndwater
2 and 4 cavity PET preform injection molding systems for 5 gallon bottles. 750 g preforms, 50 or 90 pieces per hour, mold and auxiliaries included.
Preform Injection Molding Machine Jndwater Detailed Description
JNDWATER supplies the 5 gallon preform injection molding system in two configurations: 398PET with a 2-cavity mold running at 50 preforms per hour, and 628PET with a 4-cavity mold at 90 preforms per hour. Both are servo-driven, and both arrive as a complete package with mold, dryer, loader, chiller and compressor.
Advantage:
1.Engry-saving –Response to energy saving of high oil circuit patent 20%-50%
2.Fast-Rate of fire increased by a short cycle time
3.Precision- Using semi-closed or fully loop,forming a more sophisticated control
4.Stable-Optimal design of machinery,asphalt,electrical control,close co-works withefficient cooler,forming more stable
5.Modularity-Agencies,circuit,wiring modular,can be combined with multiple injection system,the demand of different production technology
6.Durable-High-rigidity clamping structure,die without distortion
