Automatic Plastic Bottle Blow Moulding Machine

automatic blow molding machine

Brand : KHX-MACHINE

Main Features
1. After preform injection, the heat is used for bottle blowing, no need of preform packaging, storage, reheating and other working procedures.
2. Less land occupation, simple management, high degree of automation, less labor intensify (1 person can control more than 3 machines).
3. With a temperature adjustable station, suitable for complicated shape, difficult forming products (such as PP IV-solution bottles).
4.The compact structure greatly shortens the production cycle and enhances productivity.
5.Adopt variable pump and Servo Driver Motor, maximally reduce energy consumption.
6.The replacement of the mold cost is far lower than similar foreign equipment.
