Blow Molding Machine

Sipa SFR 16

Used Blow Molding Machine Sipa SFR 16


Assessment of Heating System and Preform Feeding


Firstly, a comprehensive evaluation of the entire oven system is imperative, encompassing turning-over ramps and tension wheel guides, to ensure an efficient and seamless bottle forming process.


Evaluation of Transfer Arms and Cams of the Sipa blower




An indispensable aspect pertains to the scrutiny of transfer arms and cams. These components play a pivotal role in maintaining a continuous and uninterrupted production flow. Furthermore, meticulous inspection of their functionality is essential to uphold the quality and precision of the blow molding process.


Condition of Molds and Stretching Mechanism


Equal emphasis is placed on assessing the condition of molds and the stretching mechanism. The accuracy and integrity of the molds are pivotal in producing flawless, high-quality bottles. Consequently, conducting a thorough assessment of these components is essential to ensure optimal machinery operation.
