The main components on the machine are of international famous brand. The machine owns the advantage of high level automation, reliable and stable operation and low power consumption. It is the high efficient equipment for large scale production in modern scale large enterprise.

• The ventilation cooling system is equipped on the infrared light in the heating furnace to increase the service life of the light tube and enhance the heat effi ciency of the heating furnace.
• The air flow in the heating furnace and bottle neck protection device are well designed to prevent the bottle neck from warm up influence and guarantee the ideal temperature curve on the preform.
• The preform heating adopts thyristor controlled infrared warm up technology. The temperature of every layer of the infrared light tube can be controlled independently. Alarm device is equipped for the disconnection of the tube line.
• Together with simple but fi rm structure design, the opening and closing of the die carrier is accurately controlled by the new type cam mechanism to make the replacement of the mold faster and more convenient.
• The special structure of the blowing nozzle guarantees the reliability of the mouth closing under various air blowing pressure. Unique blowing control mode enhances the quality pass rate of the plastic bottle being blown.
• The electronic checking system is capable to automatically eliminate the unformed preform or insufficient formed bottle accurately, therefore guarantees the quality of the final bottle product.
• Fully closed in structure and equipped with reliable safety door mechanism, the machine guarantees the safety of the operator to utmost extent. The machine is also equipped with several safety protection devices such as mold clamping protection device, mold locking protection device, bottom mold protection device and mold opening protection device etc. to guarantee the safety operation of all actions.

There are four distinct blow molding processes that use heated liquid plastic to create hollow objects, like bottles or other packaging. Pressure forces the material into a mold cavity, which gives the object its hollow shape. At Drug Plastics, we use all four distinct blow molding processes to manufacture our products: Extrusion Blow Molding (EBM), Compression Blow Molding (CBM), Injection Blow Molding (IBM), and Injection Stretch Blow Molding (ISBM).

In general, the size and geometry of the bottle and the type of plastic resin being used determine the best manufacturing process. We leverage our knowledge acquired from over 60 years of bottle making to choose the optimal blow molding process for every product we produce. Drug Plastics commits to deliver perfect bottles each and every time.

We believe it's important for our customers to understand the primary differences between molding processes. Why? Because understanding how we manufacture our products will help you make more informed decisions about your plastic packaging. Let's review the differences between the four distinct blow molding processes. Read further or watch our video to learn more. Each process starts the same way ' with pellets of plastic resin.

Extrusion Blow Molding

In the EBM process, we extrude the heated resin to form a parison. The parison is a vertical tube-like piece of plastic through which compressed air can pass. A two-part mold closes on the parison from both sides. A blow pin is inserted into the neck area of the bottle that blows air into it when sealing the mold. The air pressure makes the parison conform to the shape of the mold, including the threads in the neck portion of the mold.

The mold is cooled, and the bottom of the parison is trimmed. The mold opens and the bottle is placed on a conveyor belt, the top (typically dome-shaped) is trimmed, leaving the finished bottle. The EBM process is used to manufacture large-size, High Density Polyethylene (HDPE), Low Density Polyethylene (LDPE), and Polypropylene (PP) bottles with large necks.

Compression Blow Molding

CBM is a specialized form of extrusion molding. In CBM, the blow pin not only blows air into the parison so the plastic conforms to the shape of the bottle, but it also uses physical pressure to force the plastic into the neck area of the mold. This results in increased thread definition and precise bore tolerance.

Bottles with medium to large blow-up ratios are produced using CBM. The blow-up ratio is the comparison between the diameter of the neck of the bottle and the diameter of the body of the bottle. Bottles with large blowup ratios typically have large bodies and relatively small necks. The CBM process can be used to manufacture bottles that are made with HDPE, LDPE, and PP resin, and can achieve very tight critical neck dimensions.

The EBM and CBM processes also allow the weight of the bottle to be adjusted. This is done by controlling the amount of plastic in the parison. This is ideal when the contents of the filled bottle require a thicker wall, or as a conscious effort to conserve raw materials by reducing the amount of plastic. The EBM and CBM processes are also used when a bottle has multiple plastic layers (outside and inside); and when a transparent window stripe is needed to allow for determining the amount of product remaining in the bottle.

Injection Blow Molding

During the IBM process, the heated resin is injected into the mold using a long screw. This injected plastic is molded into a preform, then air is used to blow the preform into the shape of the mold. The mold is cooled and the bottle is placed on a conveyor belt after being ejected from the mold.

This process is ideal for the production of HDPE, LDPE, and PP bottles with a small to medium blowup ratio. Bottles with small blow-up ratios typically have small bodies and relatively small necks. IBM is used when manufacturing bottles with very tight neck tolerances.

Injection Stretch Blow Molding

During the ISBM process, the heated resin is injected into the machine using a long screw. This injected plastic is then molded into a preform.

Next, the preform is conditioned and prepared for stretching. The preform is stretched as air is used to blow it into the shape of the mold. The stretching of the preform increases the barrier properties of the PET bottle. The mold is cooled and the bottle is placed on a conveyor belt after being ejected from the mold. ISBM is typically used for bottles with small to medium blow-up ratios. We use ISBM to manufacture all of our Polyethylene Terephthalate (PET) bottles.
