Description

The injection stretch blow molding machine adopts injection stretch blow molding technology. It can produce high grade bottle whose bottleneck has high precision. The structure of the machine provided by Liuzhou Jingye Machine Co.,Ltd. is double-station, which include preform injection and stretch blow molding ejection. Our injection stretch blow molding machine take one-step method forming process that means the injection, stretch, blow molding process and other processes are finished one by one in this machine. This kind of product shows that it is of highly automatic with beautiful appearance of the product, accurate size and labour saving.

Applicable Materials:PP, PET and other thermoplasticity resin raw materials.
Note:We can provide customized machine and mould according to client’s requirement to meet the special need of your product

Types

1. Machine for PET Container.
WISB-35 Full-automatic Injection Stretch Blow Molding Machine
2. Machine for PP Container.
WISB-40 Full-automatic Injection Stretch Blow Molding Machine

Applications

The machine is applied widely in the areas of pharmaceutical packing, daily-use packing and cosmetic packing.

Injection Stretch blow molding process

1. This kind of machine has two mainly different methods, one is single stage process and another is two stage process. The plastic material is first molded into preforms by using the injection molding process. These preforms are produced with the bottle neck and threads (the finish) on the end. Then these preforms are packaged and fed later (after cooling) into a reheat stretch blow molding machine. In the injection stretch blow process, these preforms are heated (often use infrared heaters) above their glass transition temperature, then they will be blown into the high pressure air with metal blow molds. The preforms are always stretched with a core rod in the process.
2. In the single-stage process both preform manufacture and bottle blowing are performed in the same injection stretch blow molding machine.
The process explained: Imagine the molecules are small round balls, when put them together, they have large air gaps and small surface contact. Firstly, stretching the molecules vertically and then blowing to stretch horizontally. The biaxial stretching makes the molecules a cross shape. These "crosses" fit together and leave little space as more surface are is contacted and thus make the material less porous and increase barrier strength against permeation. This process also increases the strength to be ideal for filling with carbonated drinks.

Product Advantages

1. The injection, stretch and blowing of the machine form in one step and don’t need secondary operation by worker. The products produced by the machine have the superiority in beautiful appearance, accurate size, good sealing property and compliance with GMP requirement.
2. This kind of injection stretch blow molding machine takes full automatic one step method to save the labor and reduce labor intensity.
3. It adopts the vertical work way to reduce projection area of the mold and use lower clamping force to finish the work, so as to achieve the effect of reducing energy consumption.
4. The machine adopts the servo motor system, the energy-saving effect is more obvious and thus make the machine work steady, accuracy and reliable.
5. The mould of the machine adopts the insert structure of overall injection mould that ensure the final products only have two parting lines.
6. Our company has rich professional technology experience to exploit new kind of machine. We can provide customized machine and mould according to client’s requirement to meet the special need of your product.
7. Highly suitable for low volumes and short runs production. As the preform is not released during the entire process the preform wall thickness can be shaped to allow even wall thickness.

Service Advantages

Our company has a group of professional and technical personnel whom are long time concerned with the work of technological development in this area. We have thousands of exploitation experiences and strength of hollow container due to that there are experienced specialists who enjoy the particular subsidy of the State Council and youth backbone who has a wide range of specialized knowledge and rich practical experience. Just tell us what plastic product you want to produce and we will help you to choose the best injection stretch blow molding machine for your needs. We believe that our reasonable prices, high quality and excellent service will bring us both benefits. Choose us-choose the best!
