Injection Stretch Blow Molding Machine K28

Patented Single Stage PET processing System

The CYPET K28 is a fully automatic single stage injection stretch blow molding machine, capable of producing finished containers directly from PET resin. The system utilizes CYPET’s patented technology that uses only two stations, one for injection molding the PET preforms, and the second to stretch blow mold the PET containers. Its 280 ton clamping force allows unparalleled flexibility in production of containers up to 50Ltr in size, with up to 200 mm neck diameter.

Highly optimized, energy-saving servo-hydraulic technology as well as the use of an air recovery system as standard, reduces energy consumption by up to 40% (0.31kWh/kg of finished bottles). The machine’s generous clamping force and platen size, allows molds with higher cavities achieving higher output with less investment compared to conventional technologies. The molds’ hot runner is naturally balanced, enabling consistent mold filling for any preform weight and valve gated to eliminate stringing. Bottle ejection occurs via free drop as standard, or optionally via an automatic take out system onto a conveyor for downstream processing.

Production Capabilities

The machine can mold different types of PET containers, such as  water bottles, edible oil stackable jerrycans, wide mouth jars, personal care containers, drums and more. Medium sized containers (5ltr or larger), can be molded with a handle on the neck as one piece – saving the trouble of assembling an external handle.

The CYPET K28 can also be used as a standard injection molding machine for a wide range of plastic resins, further de-risking the investment in the machine and maximizing its utility.

All Electric Version

The all electric version is the CYPET K30E, with the same capabilities as the K28 and in addition being suitable for clean room applications.
