ISBM Blow Molding Machine

SIV blow molding machine is great equipment for producing BOPP IV bottle.

The main production flow of this equipment is as below:

(1)sending pre-cool preform onto carriers by conveying system

(2) heating preform with heater

(3) sending preform into molding cavity by mechanical clamp

(4)two-step stretching and blow molding preform inside mold

(5)taking out finished bottle

(6) automatic connection device to filling machine .Adopted smart high-accurate auto voltage control system the equipment can accurately control preform temperature and greatly save manpower, raw material and energy.

Preform molding uses servo preform loading system, pneumatic mold clamp system, unique rotary convey system, preform loading system and two-step servo stretch molding system which can accurately control stroke and guarantee even bottle thickness. Besides, the equipment uses user friendly interface and has tele-diagnosis system to ensure safer and more reliable running.

This part mainly concludes air supply, pneumatic passage, control unit and executive unit. Pneumatic passage divides into two parts high-pressure and low-pressure. Low-pressure pneumatic passage with a pressure of 0.6-0.8Mpa belongs to operating system.

It controls executive unit’s (cylinder etc) movement by cooperating with electrics and through control unit (for example: solenoid valve). High-pressure pneumatic passage with a pressure of 1.5-2.5Mpa is used to blow bottle and clamp mold.

Electrics are made of PLC, touchable screen, heater and control unit. PLC microcomputer control system adopts touchable screen user friendly interface.

Cooling system is made of two parts chilled water and cooling water, which construct of cooling pipe, pump, water chiller, valve and pipes：

(1) Chilled water is mainly used for change of blow mold heat.

(2) Cooling water is mainly used to cool the plate and bearing under the heater to prevent them from deforming.

Air exhausted system has two parts: cooling fan and air exhauster. Its function is to modify the environment temperature of preform heating zones.
