Injection Blow Moulding
The two main methods of injection stretch blow molding (ISBM) are the single-stage and two-stage processes. The single-stage process can be further divided into 3-station and 4-station machines. In the two-stage ISBM process, plastic is initially molded into a “preform” using injection molding. These preforms are designed with the bottles' necks and threads on one end. After being produced, the preforms are packaged and allowed to cool before being fed into a reheat stretch blow molding machine. In the ISBM process, the preforms are heated, typically with infrared heaters, above their glass transition temperature. Subsequently, they are inflated into bottles using high-pressure air, resulting in the final product. This efficient methodology highlights the versatility and effectiveness of ISBM in producing high-quality plastic bottles.
All-Electric Injection Stretch Blow Moulding Machine
A major step forward compared to our oldest hydraulic Biaxial series. A load of customer-focused technology, which brings many benefits, ranging from energy savings to equipment savings; in addition to the linear movements of preforms and bottles we have also the blowing station in two different phases. Equipment savings will mean one more major plus; it’s very well known that the cost of the moulds has a significant impact on the cost of the machine and it’s payback in production. Our machine will rely on the new system, patented, complete with movable mould carrier to allow the cavities of the blowing mould to be reduced by 50%.
Let’s be clearer: to blow 6 preforms, traditional technology would require 6 blowing cavities, with a clamping force of approximately 30-35 ton. With our machine we have only 3 blowing cavities and the required clamping force is reduced by 40%. Specially designed for customers who need production in limited volumes, our machine will allow them to blow simultaneously two differently shaped bottles, with an apparently similar preform and different neck.
The machine can be equipped with in line or 90° injection station. This ground breaking project will allow the machines to be upgraded and many new details to be introduced.

Injection stretch blow moulding machine characteristics
Automatic production, no need to remove burrs, no need to transport preform, greatly save raw material and labour costs.
No need secondary heating preform, along with energy saving energy saving system, can save about 30% power.
Preform forming& bottle blowing are completed in one machine, to avoid preform in the process of transportation and pollution.
Bottle screw size of neck and bottle parting line are perfect, bottle is stronger.
Injection stretch blow moulding machine is compact, from the raw material to the finished product, it can reduce equipment investment cost greatly and save workshop space (machine and bottle preform storage space).
Stable mechanical operation and low noise.
PET molding machine with a built-in error detection and alarm system, and display in the manipulation of the screen.
Machine production capacity from 5ml to 5000ml, from PET, PETG, TRITAN/PCTG, PP, PC. Only one injection blow molding machine can meet the needs of all kinds of material.
Injection stretch blow molding machine advantages
