Products and Technologies
PET preform injection-molding machines
PET preform injection molding requires accurate control of melt temperature, injection speed, pressure, cooling, and mold filling. The resulting preform must maintain consistent weight, neck dimensions, wall distribution, and optical quality because defects introduced at this stage can remain visible or affect performance after stretch blowing.
BLOWPLAS lists injection-molding machines designed specifically for PET preforms. Such equipment typically operates with multi-cavity molds and requires high repeatability in:
- Injection pressure and velocity
- Screw plasticizing and metering
- Mold clamping and opening
- Preform cooling
- Cycle synchronization
- Regrind and material-handling control
The commercial value of preform machinery is strongly influenced by cavity count, cycle time, energy use, mold-change requirements, and the ability to process different preform weights and neck standards.
PET stretch-blow molding
PET stretch-blow molding transforms heated preforms into bottles by combining axial stretching with radial expansion. A stretch rod extends the preform longitudinally, while compressed air forms the material against the mold cavity. This biaxial orientation improves the mechanical and barrier-related performance of PET containers compared with an unoriented article of similar mass.
BLOWPLAS identifies PET stretch-blow molding machines among its principal products. The relevant process variables include:
- Infrared or equivalent preform-heating control
- Stretch-rod motion and timing
- Pre-blow and high-pressure blow stages
- Mold cooling
- Bottle-wall distribution
- Compressed-air consumption
- Mold and neck-finish compatibility
These capabilities are important in beverage packaging, where container producers seek lower material use without compromising top-load strength, pressure resistance, transparency, or dimensional stability.
One-stage injection-stretch-blow molding
The BT-2S series presented by BLOWPLAS is identified as a one-stage injection-stretch-blow molding machine. In a one-stage process, the preform is injected and then stretch-blown within the same broader production cycle, reducing the need to manufacture, store, and reheat preforms separately.
One-stage equipment can be advantageous for:
- Small and medium production runs
- Containers requiring specialized shapes
- Products with demanding visual or dimensional requirements
- Applications where intermediate preform logistics would add cost
- Integrated manufacturing facilities seeking a compact process route
The principal engineering challenge is the coordination of injection, thermal conditioning, transfer, stretching, and blowing. Precise temperature management is particularly important because the preform must reach the correct forming condition without excessive cooling or thermal degradation.
Injection-blow molding
Injection-blow molding is used to produce hollow articles with controlled neck finishes and relatively precise dimensions. It is commonly associated with smaller containers used for pharmaceutical, personal-care, household, and specialty packaging applications.
BLOWPLAS lists injection-blow molding machines as part of its equipment range. Compared with larger beverage-bottle systems, injection-blow machinery often emphasizes neck accuracy, surface appearance, container cleanliness, and the repeatability of small articles.
Plastic blow molding
Conventional blow molding forms hollow products from a thermoplastic parison. Depending on the machine configuration and material, the process can produce bottles, technical containers, ducts, tanks, and other hollow articles.
The company’s product listings include plastic blow-molding machines, indicating coverage beyond PET-specific applications. The wider blow-molding field may involve materials such as high-density polyethylene, polypropylene, and other thermoplastics, with equipment selected according to melt strength, container volume, layer structure, handle formation, and barrier requirements.
Molds and automated die-change systems
Molds determine the final geometry, surface finish, neck configuration, and cooling behavior of a container. BLOWPLAS lists plastic-processing molds among its products and has also presented an automated die-change system.
Automated mold or die-change technology can reduce setup time and improve operator safety by limiting manual handling of heavy tooling. It can also support shorter production campaigns, which are increasingly relevant as packaging producers manufacture a broader range of sizes, shapes, and product formats.
Applications and End Markets
BLOWPLAS equipment serves industries that use rigid hollow plastic packaging and molded technical articles. Relevant applications include:
- Bottled water and carbonated beverages
- Juices, functional drinks, and edible oils
