There are lots of plastic parts in our daily life manufactured by One Step Injection Blow Molding (IBM). Especially blow molded bottles and containers that are some of the most common plastic parts. In the world of manufacturing, One Step Injection Blow Molding Machine is the main key to achieve the perfect injection blow molding parts.




One Step Injection Blow Molding Machine

One Step Injection Blow Molding Machine (IBM) is used for mass production of small medical and single serve bottles. There are three stations of the Injection Blow Molding process : injection, blowing and ejection. One Step Blow Injection consists of an extruder barrel and screw assembly which melt the polymer. The molten polymer is fed into a hot runner manifold where it is injected through nozzles into a heated cavity and core pin. The cavity mold forms the external shape and is clamped around a core rod which forms the internal shape of the preform. The preform consist of a fully formed bottle/jar neck with a thick tube of polymer attached, which will form the body. The preform mold opens and the core rod is rotated and clamped into the hollow, chilled blow mold. The end of the core rod opens and allows compressed air into the preform, which inflates it into the finished shape. After a cooling period, the blow mold opens and the core rod is rotated to the ejection position. The finished part is stripped off the core rod and as an option can be leak-tested prior to packing. The preform and blow mold typically have three to sixteen cavities depending on the part size and the required output. In the whole process, there are three sets of core rods which allow concurrent preform injection, blow molding and ejection.


Advantages of One Step Injection Blow Molding Machine

Efficient Production

As above mentioned, the product is made in one cycle (From Injecting Preforms to Blowing Bottles). It is ideal for mass production of injection blow molded parts especially bottles and containers.


User-Friendly Controller

One Stage Injection Blow Molding Machine is equipped with fully computerized touch screen which is easy to operate.The self-diagnostics system in the touch screen displays instant erroneous messages, which help the engineers to figure out the problem immediately.


Environmentally Friendly and Energy Saving

While producing the product, there is zero contamination and no need for an extra heater to be implemented in the machine. The In-Mold heating preconditioning feature and zero contamination will improve your branding image.



The cost-saving can be divided into two parts. Labor Cost: The machine has fully automatic operation, and together with the user-friendly touch screen, so less manpower is needed. Material Cost: While operating, there are basically zero burrs and flash. So the material usage is maximized.


Easy Availability of Replacement Parts

Replacement parts, such as the Pneumatic and Hydraulic components of the Injection Blow Molding machines, can be easily acquired in local markets.


Product Diversity and Increasing Value

One Stage Injection Blow Molding Machines are suitable for making all types of nice looking, small volume bottles for different industries like pharmaceutical, cosmetics, and households industries.
